European Settlement in the New World Essay Example

European Settlement in the New World Essay The displacement of Indians and the enslavement of Africans tarnished the early history of European settlement in the New World’. Illustrate this statement by discussing the African slave trade and relations between European settlers and the various Native American peoples. America was regarded as the continent of new opportunities, religion freedom, new ideas, innovation. In other words, it was claimed to be the New World. Many people headed to America hoping to give a new beginning to their lives. Up to this point, we expect to learn wonderfulthings about the foundation of the States. Nonetheless, the displacement of Indians and the enslavement of Africans tarnished the early history of European settlers in what it was supposed to be the New World. Besides this, there were two other developments that, together with the introduction of this system of chattel slavery, shaped life in the mainland colonies between 1640 and 1720. The English were amateurs when it came to slavery, though other Europeans were not. During the fifteenth century, the Spanish and Portuguese had already imported enslaved Africans as labourers into the islands of the Mediterranean Atlantic. The rising demand for sugar, coffee, cotton, and tobacco created a greater demand for slaves by other slave trading countries. Thus, Europeans needed bound labourers, that is, people who, by law or contract, could be forced to work. In the case of the English, the candidates for this workforce were young English men who were offered opportunities so as to work in the New World provided the accepted a seven year contract. Nevertheless, when the supply of English indentured servants began to become scarce in the 1660s, Chesapeake planters turned to Africans.

Due to this African population in Virginia started to grow. Spain, France, the Dutch, and English were in competition for the cheap labor needed to work their colonial plantation system producing those lucrative goods. The slave trade was so profitable that, by 1672, the Royal African Company chartered by Charles II of England superseded the other traders and became the richest shipper of human slaves to the mainland of the Americas. The slaves were so valuable to the open market they were eventually called Black Gold. By the end of the century, African slavery was established as the basis of the economy in the Chesapeake. The settlers went up to the west area of Africa for the selection of slaves for a great deal of reasons. That part of the country was one of the most fertile and densely inhabited regions of the continent so the trade in human beings did not depopulated the area. In Guinea, the chief consequences of the trade were political and economic. Coastal rulers served as middlemen, allowing the establishment of permanent slave-trading posts in their territories and supplying resident Europeans with slaves to fill ships that stopped regularly at the coastal forts. These rulers controlled both European traders’ access to slaves and inland peoples’ access to desirable European goods. Europeans were the main beneficiaries of this traffic of slaves. The expanding network of trade between Europe and its colonies was fuelled by the sale and transportation of slaves, the exchange of commodities produced by slave labour, and the need to feed and clothe so many bound labourers. The sugar planters of the Caribbean and Brazil purchased slaves from Africa, dispatched shiploads of valuable staple crops to Europe, and bought large quantities of cheap food. By the late seventeenth century, commerce in slaves and the products of slave labour constituted the basis of the European economic system. Europeans fought to control the slave trade. The Portuguese had at first dominated the trade, but they were supplanted by the Dutch in the 1630s. The Dutch lost out the English, who controlled the trade through the Royal African Company, a joint-stock company chartered by Charles II in 1672. By the end of the eighteenth century, independent traders were carrying most of the Africans imported into the colonies and earning huge profits. The slave codes robbed the Africans of their freedom and will power. Slaves did resist this treatment, therefore strict and cruel punishment was on hand for disobeying their masters. Slaves were forbidden from carrying guns, taking food, striking their masters, and running away. All slaves could be flogged or killed for resisting or breaking the slave codes. Some slave states required both slaves and free blacks to wear metal badges. Those badges were embossed with an ID number and occupation. Refusing to obey their masters demands created a duel crisis on the part of the resisting slaves and their demanding owners. The most common form of resistance used by the slaves was to run away. To live as a runaway required perfect escape routes and exact timing. Where to hide, finding food, leaving the family and children behind became primary issues for the escaping slaves. Later, the severe punishment had to be faced whenever a hunted slave was caught and returned to bondage. Many slaves ran off and lived in the woods or vast wilderness in the undeveloped American countryside. This group of slaves were called maroons, for they found remote areas in the thick forest and mainly lived off wild fruits and animals as food. Some of these maroons ran off, lived, and even married into segments of the Native American populations. They were later called Black Indians. Regarding relations between European settlers and Native American peoples, the latter ones enthusiastically welcomed European settlers to their shores up to the third decade of the seventeenth century. Many thought the armed Europeans would protect them from their more powerful native enemies. Natives generously shared with the settlers their belongings, supplies, food, and the skills necessary for survival in the New World. What the settlers gave them in exchange was destined to destroy them: disease, firearms, whiskey, a brutal religion totally at odds with nature, and a demand for material goods that would rob them of their independence. Within ten years of the arrival of Winthrop and his party, the natives welcome of the settlers had worn out. The settlers had appeared on the scene with two objectives in mind with regard to the Indians: secure their land and convert them to Christianity. The natives soon saw trade as the settlers means of exploitation. Sachems began to resent missionaries as interlopers interested only in preparing the way for land grabs. The English made their own laws on what for centuries had been native soil and held natives accountable to English rules. Moreover, any breach of English aw resulted in a natives being subjected to a public humiliation unknown in his or her own culture. Relations were scarcely improved by the Puritan attitude toward the natives. To the European mind, the natives were sub fiends in the service of the devil whose domain included any untamed land in the New World. Resentment naturally mounted. But it was the differing views of land and the English determination to acquire New World land that caused open warfare to erupt. It is within the context of the native view that land was to be held in common that one must understand the business arrangements between European settlers and the natives. Often the natives had no understanding of what it meant to sell land to the settlers. And according to Roger Williams, a Puritan minister in sympathy with the Indians, Europeans used the natives naivete in this regard to acquire huge tracts of land without fully explaining the exclusive rights they intended securing and without fair and proper payment. At first, the natives blithely sold tribal lands in small and large tracts, believing that ownership would not exclude them from using the land. They realized only later that what the Europeans were doing was rapidly acquiring exclusive private use of virtually all the tribal lands in New England and subjecting natives on these lands to the laws of the Massachusetts Bay Colony. One instance that reveals the conflict that arose because of the differing views of land ownership centered on the area of Dedham, Massachusetts, which European capitalists had acquired from the natives. The owners of the land actually lived hundreds of miles away-not on the land they owned in Dedham. Seeing no activity on the land, the natives believed they were free to hunt, trap, fish, build houses, and cultivate gardens there. This attitude was not removed from that of the philosopher John Locke, who so strongly influenced the thinking of the fathers of the American Revolution. He wrote that one could own the land only with which one mixed ones labourand could actually use. But the colonists were massing great estates on which they might eventually establish business enterprises, and they strongly objected to the presence of the natives on land that they now owned. Similar quarrels began to occur throughout the colonies, leading to armed hostilities. There were many conflicts between settlers and natives throughout the colonial period. One of the first major conflicts occurred in 1637. Word reached Boston in July that an English trader named John Oldham had been killed by Pequot Indians. The New England colonies raised a militia and waged war against the Pequot for a solid year. On June 5, 1637, a militia destroyed a large Pequot village at Stonington, Connecticut, and a little over a month later a military force made up of soldiers from three New England colonies tracked down the survivors of the Stonington village at a place near New Haven and slaughtered all they could find. Other Pequot men and boys who were eventually captured were sold into slavery in the West Indies. The women and girls became slaves to white settlers in New England. With their numbers decimated, their main villages burned, their stored food and supplies stolen, the few Survivors in this tribe left for the west. This was the end of the entire tribes presence in New England. Although for forty years after this incident, there was no open warfare between settlers and natives, relations between them were hardly cordial. Individuals from both camps were guilty of murders and thefts, and the English continued to gobble up land. Land disputes continued, the one at Dedham in 1668 and 1669 being one of the most prominent. There were also quarrels with the Narraganset in Rhode Island where Massachusetts Bay businessmen, under the Atherton Company, began commandeering immense amounts of Indian land. In this case, the European settlers of Rhode Island sided with the natives against the settlers of Massachusetts Bay and Connecticut. After the embittered Narragansett caused property damage near some Connecticut plantations, the New England Confederation demanded that the natives either pay a fine, which was too large for them to meet, or forfeit all their lands to the business corporation. Immediate disaster was averted when the king of England, Charles II, intervened at Rhode Islands request to side with the Narraganset and voided the claims of the Atherton Company. Still, the company tried to ignore the kings dictate and continued appropriating Narraganset land. Throughout the 1660s and 1670s, the General Courts of the Massachusetts Bay or Plymouth Colony made a habit of hauling tribal sachems before them to quiz them on rumors of conspiracies or allegiances with tribes or nationals that the bay considered unfriendly. Once these hearings were over, the court would present the defendant with a bill for court costs, as it did the Wampanoag chief, King Philip, in 1667. The reason for the disintegration of relations and the buildup of hostilities was simple: the colonists planned on and were determined to secure key Indian land as part of the expansion into the Connecticut Valley, and the Indians were determined that this would not happen. King Philip had historically been friendly with the settlers, but suspicions mounted, rumors raged on, and the English demanded that various tribes surrender their weapons. When the English suspected that the natives had not surrendered their weapons, they prepared for war in 1671, finally forcing the natives to pay ? 100 worth of goods to the colony, to recognize English law, and to accede to any colonies decisions regarding the disposal of Indian land. For four years, King Philip and other sachems inwardly seethed over the humiliation. Finally, in June 1675, after Plymouth Colonys execution of three of King Philips men for the murder of an informant, the Indian chief began his raids on settlements in a year-long war in which many native tribes sided with the settlers. Some fifty towns along the frontier were burned. By 1676, the English had lost about 2,000 people, and the natives had lost about 4,000 in battle. With the decisive defeat of King Philips forces in 1676 (King Philip himself was killed, drawn and quartered, and his head brought to Boston for display) came the virtual end of the native tribes in New England. There was no longer a question of negotiating for land or paying the usual ? 25 for an estate. All Indian land was now up for confiscation as the settlers ictated the terms for takeovers and appropriated Indian land as the spoils of war. Prisoners of war were executed by the scores, most without trial and many of whom had been friendly to the settlers. Immediately, however, New England businessmen realized the cash value of the prisoners, so many more were sold into slavery and shipped to the West Indies, Spain, and the Mediterranean. Those deemed less dangerous became bound servants in the colonies to alleviate the perpetual labou rshortage. Natives, who fifty years earlier had called the whole New England area their home, to be held in common with their brothers, were restricted to reservations. The more fortunate of them were allowed to be tenant farmers or to work as hired hands. In the 1620s, they had numbered around 75,000 people. Their people had lived in New England for thousands of years. By the 1680s, decimated by disease, alcohol, and wars with the settlers, their numbers had dropped to 20,000, only half the number of the new European settlers. One further notorious clash between Native Americans and settlers in the colonial period occurred on February 29, 1704, during a time when many tribes had sided with the French in the fight between French and English over the domination of northern New England. A company of 28 Frenchmen and 200 Native Americans launched an attack on Deer- field, Massachusetts, a town of three hundred residents, twenty miles south of what is now Vermont. Forty-eight Deerfield residents were killed, and 111 were taken hostage.

A Room with a View essays

A Room with a View essays A Room with a View by E. M. Forster is an excellent novel that depicts various significant historical aspects that concerns the 20th century. The author skillfully conveys his message through his characters by emphasizing on their constant desire to travel, contradicting the individuals of two social classes and illustrating the importance of the supreme power, i.e. the God and the Church. Forster clearly states that the fascinating world is getting smaller by traveling. Firstly, the novel itself is set in two different countries: England and Italy. The setting is established by British travelers at Bertolini, Italy, who make their way back-home to Surrey, England and finally, end up back in Italy. The Alan sisters amongst others have traveled to far off places across the world, including Greece, Rome, Athens, Delphi, Acropolis, Blue Sea, Parnassus, Constantinople, etc. Queen Victoria makes her journey to Ireland unwillingly, indicating that the Parliament has a higher power than the monarchy. Ms. Lavish on an account explains that due to a catastrophe in Venice, she fled to Venice in the past. She further adds that she travels around the world to get inspiration for her novels whereas other individuals opt for commercial studies for their love of tourism. Hence, Forster demonstrates through his amusing characters that it is an era of new ideas, questioning , deducing truth for themselves by exploring, freedom and personal satisfaction. The Victorian society is very rigid based on various social classes. Unrefined Emersons are most frequently victims of the snobbery due to the fact that they work hard for a living and are not socially acceptable. Upon arrival in Italy, Charlotte does not agree to exchange rooms with them because of the social pressure imagining what other people are going to think. She is also concerned about Lucy as she does not want her to feel obliged from a young, poor man, George t ...

Major Depressive Disorder Case Study Example | Topics and Well Written Essays - 1500 words

Major Depressive Disorder - Case Study Example She feels worse in the mornings, guilty and hopeless, with suicidal ideation and has developed increased psychomotor retardation. She thinks she is ruining her family, who would be better off without her. These signs and symptoms indicate that she has Major Depressive Disorder (MDD), as defined by criteria in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision (DSM-IV-TR) (American Psychiatric Association [APA], 2000). The criteria state that more than one important aspect of MDD, such as sustained depressed mood, anergia, anhedonia, disturbed appetite and sleep, psychomotor retardation, suicidal thought, negative thought, hopelessness, or poor concentration, should be present for no less than two weeks and not related to somatic effects, caused by substance abuse or adverse reactions to medication. Depression is the most widespread disorder in relation to mental health. According to World Health Organisation [WHO] (2001), people suffering from depression account for 5 to 10% of the population. The 'Bettering the Evaluation and Care of Health' survey (AIHW, 2007) reported that it accounted for 33.7% of mental health disorders managed by general practitioners in Australia in 2003-04. Most studies show that the development of MDD has a higher incidence in females than males in their life time, being found in females twice as much as in males (APA, 2000; Varcarolis, 2006, pp.326-327; WHO, 2001). Typically, MDD is more likely to occur in females aged between 20 and 40 years old (WHO, 2001). Causes assumed include responsibilities of multi-tasking, for instance, domestic and office work, wife and parenting roles, or the menses might contribute to the prominent prevalence of depression in females (APA, 2000; WHO, 2001). However, race, earnings, education or matrimony are not related to the frequency of MDD (APA, 2000; Varcarolis, 2002. p.454; WHO, 2001). 2. Pathophysiology of depression: Depression arises due to multifactorial causes, including biochemical, cognitive, hereditary and environmental factors, and sleep abnormalities (Varcarolis, 2002, pp.456-460; Varcarolis, 2006, pp.330-333). In Isabel's case, a reasonable assumption would be that the major pathophysiologic causes might be biochemical, cognitive factors, and sleep abnormality. There are many studies to indicate that biochemical imbalance can cause depressive disorders, in relation to certain neurotransmitters, mainly serotonin, noradrenaline and dopamine in the brain, which are known to play a role in the regulation of mood (Varcarolis, 2002, pp.456-460; Varcarolis, 2006, pp.330-333). The dysfunctional regulation of serotonin is related to decreased sex drive, appetite and sleep disturbance, as serotonin is particularly important in controlling sleep, appetite and sexual drive (Varcarolis, 2006, p.331; Zarate & Charney, 2003, pp.464-468). Reduction of noradrenaline can lead to loss of energy, interest, concentration, and decreased sexual drive (Varcarolis et al., 2006, pp.460-464; Zarate & Charney, 2003, p.464-468). The depletion of dopamine can be associated with loss of motivation and interest, because it contributes to the stimulation of the system of circuits of motivational behaviour in

Immunization and Antibody Production Assignment Example | Topics and Well Written Essays - 750 words

Immunization and Antibody Production - Assignment Example In encountering the antigen, the body can only do so through natural situations or artificial. In the natural situation, we consider attack by antigen of specific ailment such as small pox. The antigen will cause clinical symptoms and the body will react by producing antibodies against the small pox. In the artificial antibody production, not the virulent form of the antigen are used but those that are killed or attenuated and have no ability to caused clinical symptoms unless one is immune compromised (Goldsby 2005). Antibody Formation There is no difference whether antibodies are naturally produced or artificially produced, there will only be difference in the antigen part, this is because that antigen of the natural simulation are real and do cause clinical symptoms. Those of artificial stimulation are not able to cause clinical symptoms since they do nit have the virulent parts but structurally resembles the real antigen. Given the fact that antibodies are simply modified globuli n, their formation is closely relate to that which involves globulin formation (Goldsby 2005). The first step involves the antigen being held at the site where antibodies are being produced and synthesis of the antibody will be initiated around the site where antigen molecule is found.... In the contrary, if the forces between the ends of the chain and that to the antigen are weak, it will necessitate the release of one end of the antibody from the antigen since it will dissociate (Lydyard and Whelan 2011). The dissociation of one end of the chain from the antigen will make the centre of the chain to coil forming a more stable configuration that will results in to a complete antibody. The eventual process is the dissociation of the antibody from the antigen and floats away as a free antibody. Once the antibody has been formed, it is memorized into the body and in case of second attack with the same antigen; there will be numerous production of the antibody that always leads to faster clearance of the antigen hence faster recovery from the antigenic attack. 2. Evaluate the effects of mass immunization programmers Immunization is the introduction of attenuated or killed antigens into the body of healthy persons such that the body can be triggered to produce in response, antibodies that will combat live antigens of the same nature in future. Vaccines are very specific and when one is immunized a gains a certain disease; they only become protected against that disease and not any other. Immunization can be active or passive depending on the nature of the antigen that are used to make the body respond through antibody production (Plotkin 2006). Immunization is therefore scheduled when there s an outbreak of a disease in the offing. Mass immunization is therefore an immunization program that is intended for a large number of people within one or several places in relatively short time. Mass immunization is therefore able to provide control for contagious diseases that are envisaged

Prevention of Adductor Muscle Contraction During TURBt

Prevention of Adductor Muscle Contraction During TURBt Effectiveness of Spinal anesthesia combined with Obturator nerve block in the prevention of adductor muscle contraction during Trans-Urethral Resection of Bladder tumor (TURBt) in Razy University Hospital in Rasht (2012-2013) Cyrus Emir Alavi MD[1], Siavash Falahatkar MD2, Siamak Rimaz MD4, Mohammadreza Naghipour MD3, Mehdi Jafari MD5, Koshrang Hossein MD1, Alaeddin Asgari MD2Ç‚ Nadia Rastjou Herfeh B.S6 Assistant Professor, Anesthesiology Research Center, Guilan University of Medical Sciences Professor of Urology, Urology Research Center, Guilan University of Medical Sciences Associate Professor, Department of Community Medicine, Guilan University of Medical Sciences Anesthesiologist, Anesthesiology Research Center, Guilan University of Medical Sciences Anesthesiology Resident, Anesthesiology Research Center, Guilan University of Medical Sciences Urology Research Center, Guilan University of Medical Sciences Ç‚Co-responder Author Introduction (final) Bladder cancer is the fifth most common human malignancy and after prostate cancer. It is the second most frequent genitourinary tumor. (1) Spinal anesthesia is the technique of choice for Transurethral resection of bladder tumor (TURBT), since it enables early recognition of symptoms caused by over hydration, transurethral resection of prostate (TURP) syndrome, and bladder perforation. (2)Since the patients are diagnosed with bladder cancer, aged 65 and over, due to long-term smoking, these patients have underlying pulmonary disease, coronary artery disease and diabetes(3,4) ,so choosing General anesthesia for preventing complications such as Obturator nerve stimulation and bladder perforation is a significant risk factor for this mentioned group.Although spinal anesthesia provides optimal anesthesia, pelvic floor relaxation and perineal laxity, Jerking of Obturator nerve motor would not be prevented by spinal anesthesia(5).So for the urologic surgeries, Obturator nerve block (ONB) for suppressing the Obturator reflex during transurethral resection of lateral bladder wall has been prevalently used(6) .in the case of direct stimulation of resectors, there would be a sudden , tempestuous adductor muscle contraction.This is potentially risky, which can cause an increase in the risk of serious complications for example Bladder wall perforation, incomplete tumor resection, vessel laceration, and Obturator hematomas.(7,8,9) Although this procedure is not morbidity-free, the reports of potential complications are few. (10 ,11,12) While hemorrhage is common, bladder perforation is perhaps one of the scariest complications with an incidence of 0.9% to 5%. (12,13) the most important symptoms are disability in bladder distension, abdominal distension and tachycardia. (14) Significant bladder perforation during TURBT for various reasons should be concerned. First, if prior to completion of resection, the perforation would be discovered, retained cancer in the bladder would be the consequence of such imposed termination of surgery. Second, cancer cells can distribute by means of the opening in the detrusor, and the risk of pelvic or remote disease recurrence would be increased. And the last one, immediate intravesical chemotherapy after TURBT for lessening the risk of recurrence is recommended by the updated European Association of Urology and American Urological Association guidelines. (15) Since Obturator nerve (ON) stimulation during resection of tumors is located in the inferior portion of the bladder and lateral wall of the urinary bladder would Increase the risk of bladder rupture. (14) There are different strategic options for avoiding these complications during transurethral resection of bladder tumors (TURBT) such as adopting general anesthesia with muscle relaxants, lessening the intensity of the current of the resectoscope, using laser resistors, Obturator nerve blockade (ONB), etc. Selective ONB along with regional anesthesia may be efficient to avert adductor spasm (16,17) As few studies adopted Obturator nerve block in Preventing Adductor muscle Contraction, which confirmed this method was effective. (18,19) This double-blind, randomized study was undertaken to investigate further and provide more accurate results about Spinal anesthesia combined with Obturator nerve block in Preventing Adductor muscle Contraction and bladder perforation during TUR-BT. Material and method: After the approval of the Guilan university of medical science ethics committees and obtaining written informed consent, 30 patients aged between 60-85 years belonging to ASA physical status III –IV, having inferolateral tumors of the bladder who were scheduled for transurethral resection of bladder tumor were divided into spinal anesthesia (SP) and spinal anesthesia combined with Obturator nerve block (SOB). The exclusion criteria included, patient refusal, advanced cardiac disease, allergy to local anesthetics, pregnancy, patients on anticoagulants or anti-platelet drugs, neurological diseases affecting the central nervous system. In the first group of patients, Spinal anesthesia was performed at L4-L5 interspace with the patients in the sitting position using a 25- gauge needle and 2.5cc of 0.5% Marcaine was injected then the patients were placed in the Trendelenburg position at an angle of 15à ¢- ¦for 5 or 10 minutes. After being sure about the right amount of anesthesia, the patients were placed in a lithotomy position and Transurethral resection of the bladder tumor was carried out. In the second group after placing the patients under the same method of spinal anesthesia, Obturator nerve block was performed using the classical approach in the supine position by an experienced anesthesiologist. For Obturator nerve block, the initial insertion point was determined 1-2 cm caudal and 1-2 cm lateral to the pubic tubercle. A 22-gauge 10-cm nerve stimulator needle was inserted perpendicular from the puncture site in a slightly medial direction until the tip of the needle made contact with the inferior border of the superior pubic ramus and then the needle was redirected further lateral and caudal to be put in the Obturator-channel. The obturator nerve is located 2 to 3 cm of the initial point of contact with the pubic ramus. Nerve stimulation delivered a constant current with a frequency of 1 Hz and a current of 1mA which is maintained throughout the stimulation. After Twitching in the tight adductor muscles, amperage was reduced and the stimulation needle advanced towards the nerve until the first contraction in the adductor muscles with electrical stimulation of (0.3-0.4 mA) occurred. Then after aspiration (to confirm the needle is not in the vessel) 15cc 1% Lidocaine was injected and the patients were placed in the lithotomy position and Transurethral resection of the bladder tumor started. We monitored NIBP, pulse, Spo2, ECG intraoperatively and the patient was observed specially for adductor spasm, bladder perforation during TURBT in both groups. Findings: The subjects of the two groups were comparable with respect to age, sex ratio, location of tumor, ASA class. Since the patients were diagnosed with bladder cancer, aged 65 and over, due to long-term smoking, suffer underlying pulmonary diseases, coronary artery diseases and diabetes, so for preventing complications such as Obturator nerve stimulation and bladder perforation, General anesthesia could not be used. Fishers exact test demonstrated that, there is no significant correlation between sex, Patient Age Group, Location of bladder tumor, ASA class in the two mentioned groups of patients suffering from bladder tumor. (table1). However jerking and surgeon‘s satisfaction with patients’ status in two groups were statistically significant.(P=0. 006) (table1). The obturator nerve block was done in two patients of the spinal anesthesia (SA) group due to severe adductor muscle jerking and severe underlying diseases (asthma or a history of cardiovascular disease). Due to sev ere adductor muscle jerking and not having underlying diseases, general anesthesia was done in two other patients. In three patients in the spinal anesthesia group (SA) leg jerking was slight and during cauterization the problem was resolved by controlling the leg movement.Also, there was no significant correlation between using general anesthesia due to ineffectiveness of regional anesthesia in two groups (P=0.1). (Table 1) Discussion: The endpoints of the current study were to investigate the effectiveness of Obturator nerve block in preventing the Adductor spasms and also to investigate surgeon satisfaction. Spinal anesthesia combined with Obturator nerve block in the prevention of adductor contraction and its related complications during TUR-BT is effective. Spinal anesthesia (SA) combined with Obturator nerve block (SOB) would increase surgeon satisfaction during TURBT surgical procedures. In a study done by Patel et al., he reported that Adductor spasm caused bladder perforation in 2 TUR-BT patients, which spinal anesthesia was applied and one patient was in the need of emergency laparotomy. (19) Interestingly, in our study there was no bladder perforation, which is considered as a result of being very precise and careful about the patients’ Obturator spasm and in the case of observing any sign of spasms the patient ‘s position was changed to Supine and after blocking the Obturator nerve the patie nt would be placed to the previous Lithotomy position. The obturator nerve block can be performed using various methods and techniques. And in our study Obturator nerve block was carried out using the technique described by Labat because the proximal nerve would be blocked and blocking was more effective compared to the inguinal nerve blocking. It should be mentioned that in our study there was no bladder perforation, which can be considered as a result of cautious and meticulous monitoring during the surgery. In a study which TURBT was performed on 50 patients, the patients were divided into two groups, The first group of 25 patients underwent spinal anesthesia, and the second group of 25 patients underwent spinal anesthesia (SA) combined with Obturator nerve block (SOB). In the (SA) group, almost all the patients of group (SA) suffered contraction of the adductor muscles and disturbed the surgeon. But in the spinal anesthesia (SA) combined with Obturator nerve block (SOB) group contraction of the adductor muscles did not occur in most patients. Bladder perforation occurred in two patients in the spinal anesthesia (SA) which lead to Emergency laparoscopic surgery in one patient. The results of the study demonstrated that Obturator nerve blockage is an effective way to prevent adductor muscle spasms and its related complications in patients who are undergoing TUR-BT which is similar to our study.(19) In another study which bladder tumor resection was done on 60 patients aged 18_80 years old with ASA I III ,30 patients were randomized into the spinal anesthesia group (SA) and 30 patients were randomized into the spinal anesthesia (SA) combined with Obturator nerve block (SOB) group. The regional anesthesia was done with 5cc of Levobupivacaine and 5 cc of 0.5% Nacl When the level of sensory block reached T10, adductor muscle spasms were recorded during the surgery.The frequency of adductor muscle spasms and the surgeon satisfactory were assessed. Surgeon satisfaction in the spinal anesthesia (SA) combined with Obtur ator nerve block (SOB) group compared to the spinal anesthesia (SA) was significantly higher (P One of the limitations of our study was a relatively small sample size, caution needs to be applied concerning the generalizability of the research findings and further comprehensive work with larger sample size is suggested. The conclusion of this study showed that Obturator nerve blockage is effective in preventing adductor muscle contractions and its related complications during TURBT surgery and also using spinal anesthesia (SA) combined with Obturator nerve block (SOB) during TURBT surgical procedures would increase the surgeon satisfaction.

It is being submitted for the BTech Degree at Cape Peninsula University of Technology, Cape Town.It has not been submitted before for any degree or examination in any other University. _______________________________________________ (Signature) Signed in Cape Town this _____________ day of ______________________ 2011 Abstract The influx of migrants to cities is placing a huge burden to infrastructure delivery in the Western Cape. This burden leads to the need for shelter and that in turn means that land is invaded illegally. The population now creates informal settlements. The rise of informal settlements leads to the lack of basic infrastructure such as water and sanitation.The environmental impact increases like pollution and that increases human health and gives rise to air-bone disease. As a result people tend to use open fields to defecate, illegal dumping, discharge of untreated waste water into wrong streams. The full range of technical options for providing adequate basic sanitation is still not widely known nor are the characteristics of the different options well understood. In particular, there is little appreciation of the long-term financial, environmental and institutional implications of operating and maintaining the various sanitation systems.As a result, in many cases communities and local governments are choosing technical options that, in the long term, are unaffordable and/or unsustainable. C hallenges arise from the wide range of options available and the differing environments and conditions to which each is suited. On-site sanitation is the main form of excreta disposal in most sub-Saharan African cities and will remain the most appropriate level of service for the urban poor in the medium term. Despite heavy public investment in sewerage systems in most primary and some secondary cities, typically only 10-15% of the urban population benefit from access to the sewer network.About 80% of the urban population depends on on-site facilities such as septic tanks and pit latrines which, unlike sewers, are usually the responsibility of households.

Sanitation must respond to the demands of communities and should link to improved hygiene awareness. For people to benefit from sanitation improvements, everybody must understand the link between their own health, good hygiene and toilet facilities. 44 2. Communities must be fully involved in projects. DWAF is only the regulator. Citizens have rights but also responsibilities in taking charge of their own health. 4 3. Sanitation must be provided in conjunction with water supply and other municipal services. 44 4. Sanitation is more than just toilets; it must be accompanied by environmental and health education. 44 5. Access to basic sanitation is a huma n right. 44 6. Local government has the constitutional responsibility to provide access to sanitation services. 44 7. Scarce public funds must be prioritised to help those most at risk. 44 8. Limited national funds should be fairly distributed throughout the country. 44 9. Water has an economic value and must be protected through sanitation. 44 10.Polluters must pay to clean up the water and the environment they have polluted. 44 11. Sanitation must be financially sustainable. 44 12. The environment must be protected when sanitation systems are set up and run. 44 5. 7. 1What will the Basic Household Policy Achieve? 44 CHAPTER 6 Recommendation and Conclusion45 References47 Appendices48 Appendix A.

In order to be sustainable a sanitation system has to be not only economically viable, socially acceptable and technically and institutionally appropriate, but it should also protect the environment and the natural resources.When improving an existing and/or designing a new sanitation system, sustainability criteria related to the following aspects should be considered, health, includes the risk of exposure to pathogens and hazardous substances that could affect public health at all points of the sanitation system from the toilet via the collection and treatment system to the point of reuse or disposal. This literature review covers types of sanitation, characteristics of sanitation, sanitation provision policy, criteria for selection of sanitation, conclusion. Backgroun d and MotivationThe influx of migrants to cities is placing a huge burden to infrastructure delivery in the Western Cape. This burden leads to the need for shelter and that in turn means that land is invaded illegally. The population now creates informal settlements. The rise of informal settlements leads to the lack of basic infrastructure such as water and sanitation. The environmental impact increases like pollution and that increases human health and gives rise to air-bone disease. As a result people tend to use open fields to defecate, illegal dumping, discharge of untreated waste water into wrong streams.Informal settlements by their nature are quite densely populated and access through the settlement is quite hard. Basic services are larking due to the fact there are no structures that govern the raise of settlements and the need to deliver basic sanitation services increases. There is a huge need to analyse which technology functions within the limits experienced in informal settlements. Research problem The influx of migrants from rural area impoverished and densely populated areas in South Africa towards prosperous regions is creating immense pressures on the existing infrastructure.The conditions of life to informal settlements tend to be poor, with low mobility, and difficult access to health, education, recreation and sanitation. Informal settlements are created without planning and basic infrastructure. Due to the large number of sanitation technologies available and dynamic of these informal settlements, the choice of suitable and sustainable sanitation technology is of utmost importance. Currently, sanitation services provided are not accepted by settlers. Where it is supplied, it is vandalised or misused.This results in unnecessary pressure on decision makers to provide adequate sanitation and loss of investment. Research Question Which is the most practical low cost sanitation technology that can be provided for informal settlements in the We stern Cape? Objectives and outcomes The aim of this work is to investigate the existing sanitation technologies provided to informal settlements in the Western Cape. To investigate available sanitation technologies provided in informal settlement (Cape Flats) technology by outlying, (advantages & disadvantages) from operational, design, maintenance and cost perspective.To classify the types of sanitation according to the characteristics; (dry or wet sanitation; individual or communal). To select the most suitable sanitation options. Recommend the most suitable option. A questioner will be used to find view points of the community within informal settlements. Operational costs and Structural costs per unit Significance This study intends to provide a Better Understanding of sanitation facilities within the Western Cape within informal settlements and to compare the cost implications of such facilities. DelineationThis study will focus only on the sanitation facilities within informal settlements in the Western Cape. The research will compare sanitation facilities provided for highly serviced areas within the Western Cape and the design for formal settlements will be mentioned. Assumptions The expected results of the study are as follow: †¢An overview of sanitation technologies provided to informal settlements †¢Outline key criteria used for selecting the area for the technology †¢Provide a cost effective sanitation technology for informal settlements MethodologyThere will be three (3) informal settlements around the Western Cape that will be selected based on the type of sanitation provided. (Kuyasa, New Crossroad and Nyanga). Field visits will be conducted to look at each sanitation type provided for the people of that particular informal settlement. Visual assessment will used as a way of assessing the facilities at selected case study sites. The assessment will be done with the following: -Design -Operation -Maintenance operations & cost effec tiveness -Interview with a Water & Sanitation official -Views of usersOrganisation of dissertation Here you must describe briefly how the dissertation unfolds. Don’t just list the chapter headings – say a little about each one.

Simply state what is covered in each chapter and in what order, to reveal the logic and structure of the dissertation. Do not give any proofs, arguments or results here.Complete this section last to ensure it describes the dissertation accurately. Literature review and theory This chapter is about the comparison of low cost sanitation technologies provided to informal settlements Introduction The main objective of a sanitation system is to protect and promote human health by providing a clean environment and breaking the cycle of disease. In order to be sustainable a sanitation system has to be not only economically viable, socially acceptable and technically and institutionally appropriate, but it should also protect the natural resources and the environment.When improving an existing or designing a new sanitation system, sustainable aspects should be considered. Institutional appropriateness, sanitation technologies should be managed at the lowest appropriate level, such as municipalities. The household is a major factor in sustaining human health and the environment. Beneficiary communities from the provision of sanitation technologies, or from improvements to existing sanitation technologies, must be partners in the planning, implementation and, where appropriate, operation and maintenance of these technologies or improvements.Of course, sanitation planning cannot be done in a wholly decentralized way: there has to be a coherent city-wide approach to sanitation , but the planning process has to take into account the views of the intended beneficiaries and recognise that the sanitation solutions for very poor, poor and non-poor households are likely to be very different. Affordable sanitation technologies must be affordable for the households using them. In the Western Cape in particular consideration must be given to the affordability of sanitation technologies for poor and very poor households.Purpose of Sanitation Technologies Background The prime purpose of a sanitation system is to break the disease cycle caused by the bacteria in human excreta. To do so, the system has to combat exposure to infection through all the stages from the generation of excreta to their final disposal or reuse. It is important to emphasise again that human behaviour is crucial and fostering behavioural change is a key component of sanitation system planning. In this chapter, though, we are concerned with the functional elements of the system.While individual components will vary considerably with local circumstances and will differ from community to community, the division into elements creates flexibility and choice in developing appropriate solutions. Planning Principles for Sanitation Facilities There are a few principles that lead to beneficial changes for the community and the city as a whole. Below are the six (6) principles for affective strategic planning: 1. Respond on sound finance Service provision should respond to what the potential user wants and willing to pay for. 2. Focus on sound financesIntended users’ willingness to pay for sanitation systems will not be possible for expansion for facilities required. 3. Develop incentives for good practice Individuals and organisations act in a way that ensures the on-going availability of functioning sanitation services need to be incentives for good practice. 4. Involve stakeholders in appropriate ways Groups, individuals and organisation with an interest in some particular subject, in this case sanitation become stakeholders. All stakeholders need to be involved in developing policy context for sanitation acting as intermediaries between service user and service providers. . Take a wide view of sanitation Stakeholders should look beyond local solutions to narrowly defined problems and recognise the links between different sanitation services. Excreta disposal, solid waste management and drainage are interrelated and the impact of improvements in one will be reduced if they are carried out without regard to the others. 6. Take management steps towards intermediate objectives This principle is derived from the incremental approach to the development and implementation of strategies identified, when considering steps of improving set objectives.ELEMENTS TO BE CONSIRDED FOR SANITATION PURPOSES Five elements which need to be considered separately are as follows: †¢ The toilet – there is a wide range of latrines, water closets, urine-diversion toilets, etc. , that may be considered, depending on local circumstances. †¢ The collection system – septic tanks, pits, vaults, drums, may be appropriate in different environments. †¢ Transportation – large or small sewer systems, motorised, mechanical or manual haulage may need to be considered. Treatment – systems vary from sophisticated wastewater treatment plants and sludge digestion to simple composting systems and soil filtration. †¢ Use of sanitation products – urine, composted excreta and biogas are all important resources. If all five (5) elements for sanitation are adhered too then, Health, which is one of the aspects which include the risk of exposure to hazardous substances and pathogens that could affect public health at all points of the sanitation system from the toilet via the collection and treatment system to the point of reuse or disposal.Aspects such as hygiene, nutrition and improvement of livelihood achieved by the ap plication of a certain sanitation system, as well as downstream effects needs to be prioritized. Selection of Appropriate Sanitation Technologies The selection of appropriate sanitation technologies within informal settlements either locally (SA) or internationally, should be considered. . The physical environment and technical feasibility in which it can be installed (sanitation facility) for example; consideration has to be given for (altitude, ground slopes, soils, hydrogeology, housing density, liability to flooding and local climate.The selection must also be compatible both with local socio-cultural practices and preferences and with local socio-economic conditions, with the ability to pay for the sanitation arrangement selected and also willingness to pay for services rendered. Any selected low cost sanitation for any given community has to comply with the six (6) principles for sustainable sanitation. Low cost sanitation technology Sanitation is divided into two broad groups : on site and off site systems.The technologies are further divided into three (3) reuse categories: centralized reuse, intermittent reuse and decentralized reuse and these leads to different sets of sanitation solutions. Household or local community level is Decentralized reuse (a house block). Natural drainage basins within an urban area are Centralized reuse level (town, city), wastewater collection is required followed by wastewater treatment. Pit latrines, pour-flush toilets and septic tanks are all intermittent reuse which refers to on-site systems. Conventional sewerage is not covered as it is too expensive for informal settlements (IWA, 2004).Service delivery in a recent inventory indicates that most of the informal settlements are severely lagging behind in sanitation coverage. Government’s current approach is to aim to supply informal settlements with toilets to be shared within five (5) households. Most of the toilets are locked and their maintenance relies on the users. In the Western Cape especially in the Cape Flats area the types of toilets that are mostly used are chemical (Nyanga) and bucket system (New cross) as shared facilities while VIP and UDS are considered as individual facilities.The options mentioned are not always available or suitable for the informal settlements due to the nature of the settlements. These services are considered as emergency services but however remain with the communities for a long period of time (Mel’s et al, 2009). Institutional technologies for sanitation Institutional technologies for sanitation within South African government structures need to incorporate accountability. During the planning phase all sanitation technologies are prone to mismanagement (including sanitation selection).An assessment for the comparison of sanitation technology needs to include, who is responsible for what and the likelihood that these responsibilities can and will be effectively discharged over the appropriate tim eframes (short, medium and long term commitments). A non-prescriptive professional attitude and in depth local knowledge is required for assessment purposes (Mara et al, 2001). Comparison of the two arrangements is vital because they deal with people and government entities on how to handle sanitation. The CoCT plays a critical role in identifying the need for sanitation in each community. Mobile Communal Sanitation FacilitiesDue to the ever increasing need for free land and lack of space in our urban areas, alternative technologies in order to meet the sanitation demand and respond to the communities need to be made available. Temporary sanitation facilities such as the Mobile Communal Sanitation Facility (MCSF) have been introduced recently in areas where sanitation is to take place (Muanda, 2010). Types of Mobile Communal Sanitation Facilities Mobile Communal Sanitation Facility (MCSF) varies in terms of their design, operational and use requirements. MCSF can be classified accor ding to their operational requirements.In practice the common types that are found are either dry (not requiring water) and wet (requiring water). A system that uses both scenarios has been identified as an improvement solution dealing with various situations. Wet system This type of system requires water for its operation. There are several types of such systems that are being used throughout the world and in Africa such as the DMT (dignified mobile toilet). There are solar powered toilets, sewer connected mobile toilet. Mostly in South Africa the most commonly used system is the Kayaloo and Mobisan (Parkison et al, 2008). Dry systemThis type of sanitation system does not require water for its operation. There are a few in South Africa such as the Mobile Pit toilet. In the international arena the following system for dry systems technologies include the wheel toilet (Burkina Faso), composting mobile toilet (France), tricycle toilet (India and Sri Lanka) {Pickford, 1995}. Combined s ystem This type of system is a dual system that can be used as dry or wet sanitation; it can operate without the availability of water or sewer. In the international arena, the NMT (Nepal Mobile Toilet) is the commonly used system under this category (Parkison et al, 2008).South African perception of MCSF The perception of users of mobile sanitation facilities are context based. The most preferred type of sanitation in South Africa is the individual full waterborne flush toilet. Communities within informal settlements are demanding that this type of sanitation should be provided to them at any cost regardless of the type of topography, shelter or the status of the land occupied. MCSF are seen by communities that the level of service is closer to that off the full flush toilet despite the communal status of the facility and communities are comfortable using it.Communities believe that this type of sanitation provides dignity and privacy compared to other types of sanitation in the ar eas. The slow pace of delivery and the long waiting for the provision of the individual sanitation has changed people’s perception recently. Most of the communities feel that the type of technology brought for a temporary basis has turned up to be a permanent solution (Grootboom, 2010). Operational Requirements City of Cape Town (CoCT) for example most of the settlements (75%) are located on land that is owned by the municipality and a large share which is (22%) is located in private lands.Consent from the owner has to be obtained by the Water Services Department in order to deliver services on site. Permission by many owners is not given due the fact that communities will make their temporally settlement a permanent one. A major constraint for sanitation service provision is the high density of settlements. Dry system The operation of this system does not require water for its operation and this is how the dry system is defined. Dry mobile sanitation system requires a locati on where the facility needs to be installed and the disposal point or discharging excreta when the box is full at the bottom of the system for cleaning purposes (Scandura & Sobsey,1997). 2. 5. 2 Wet system The wet system for mobile sanitation requires water and sewer in order to make the system operational. A toilet bowl is connected under this sanitation system using a pipe linking to the sewer or septic tank. The system depends on water and cannot function if water is not available. In cases where there is no sewer line, the wastewater is pumped out and taken to a disposal site (Dorrigton, 2000). 2. 5. Combined system The combined system was designed to overcome the unavailability of water and the effects that can happen to the operation of such a system. It combines both systems and can be operated without water and with water (Parkison et al, 2008). Implementation Challenges in South Africa Communities in needy areas are waiting for the implementation of sanitation technology th at will provide dignified sanitation to them. The success for the implementation should be designed in such that all the parameters of the technology are not compromised.In the past the focus was mainly on the technology of the sanitation facility, and recently the attention has shifted to the implementation methods of sanitation technologies. Implementation means the process of introduction of sanitation in communities, not necessary the design, but the development process of sanitation. Introduction of the strategy and approach towards the community is vita (Classen, 2003). Professionals in this field feel that the implementation plan should have the environment as the first priority, then after the technical aspects to meet he human societal needs, and finally the economic requirements with these communities. It has become clear from, human societal needs are important and technology must help achieve this basic needs (Grootboom, 2010). Implementation Challenges at Provincial lev el The role of the provincial government needs to be clarified in the funding of urban infrastructure investments and the planning and the delivery of sanitation services is of utmost importance. A key challenge is the lack of capacity for sanitation promotion and progress monitoring.Evasion of funds that are exclusively allocated to sanitation is affecting service provision (Grootboom, 2010). Implementation Challenges at City level Key challenges at municipal levels are related to the following issues: The lack of mechanisms bearing in mind the range of organizations that have a stake in sanitation for inter-agency collaboration on planning and service delivery. Not all municipalities at present accept that there is a problem with excreta disposal. For the achievements of national sanitation goals there is a lack of incentives and accountability.There is a shortage of capacity within the municipality in infrastructure development, planning, service delivery and sanitation promotion . Poorly understood and complicated mechanisms for accessing and allocating capital funds. The private sectors service delivery and maintenance in the safe removal, treatment and disposal of septic tank is under-developed and unregulated. Existing infrastructure is poorly maintained and operated (Grootboom, 2010). Implementation challenges within the community and household level Communities need to play a role as the intended usurers in the implementation of sanitation facilities.The challenge occur at this level, when limited appreciation of the need for safe disposal of wastewater. In most cases those that occupy land illegally are excluded from municipal projects and planning processes thus posing threats to the provision or implementation of sanitation services (Classen, 2003). For any technology to be embraced by the community they have to be involved from the inception phase, design phase and during the construction phase so that they can embrace the services being rendered b y government institutions.CoCT and Local government face a huge back log of housing projects that can play a role in elevating sanitation stumbling blocks within informal settlements.

Types of Sanitation Facilities The type of sanitation facilities listed below can be found throughout the Western Cape.The type of technology used for a particular settlement depends on the following elements which determine the final product being utilised i. e. topography, population, water resource and availability of the facility. Improved sanitation facilities This are facilities which are not shared or public, for example; flush or pour flush, piped system, pit latrine, septic tank, ventilated improved pit latrine with slab and compositing toilet (Franceys et. al 1992). Unimproved sanitation facilitiesExcreta is flushed to the street, yard or plot, open sewer, a ditch, a drainage way or other location pit latrine without slab or open pit, bucket, hanging toilet or hanging latrine and no facilities or bush or field (Lemer, 1996). Unimproved sanitation (bucket system) Design and function In the South African context the bucket is always black, pvc and is about 38 cm in diameter at the top and 30 cm at the bottom and has adequate handles for lifting and carrying. The collection chamber is situated below the squatting seat.All the chambers are open at the rear of the latrine, into the service lane used for collection. The collection chamber must be fly and animal proof. The chamber needs to be ventilated by means of a pipe vent carried to roof level of the superstructure (Pickford, 1995). Collection and conveyance of buckets On a weekly basis collection are done and gets replaced with a disinfected bucket. Buckets that are emptied into a tank and are returned immediately the practice should be condemned unreservedly.The time of the collection should be done in partnership with the community affected. Buckets are emptied at the disposal sites, thoroughly washed, and disinfected with phenol or creosol type of disinfectant before being stores away and re-used (Pickford, 1995). Improved sanitation (Septic tank) Th e most satisfactory unit all water-carried systems and the most useful system of disposal of excreta and other liquid wastes from individual dwellings, small groups of houses, or institutions located in informal settlements out of reach of sewer systems.The septic tank consists of a covered settling tank into which the raw sewage is led by the building sewer. Inside the septic tank the processes constitute the primary treatment of raw sewage; and those which occur in the disposal field form the secondary treatment. All liquids wastes, including those from bathrooms and kitchens, may be sent to the septic tank without endangering its normal operation. Contrary to popular belief, recent research has shown that sullage waste can and should be discharged into septic tanks (Lemer, 1996).On-site sanitation As it was mentioned before that there are two types of sanitation systems in this instance the On-site sanitation systems is generally designed and must operate in such a way excreta is deposited into a man-made container, usually a subsurface excavation or tank. The common trend to all forms of on-site sanitation is that decomposition process and settlement is performed on-site. This is the most low-cost sanitation system as it has various types of pit latrines. They can be either wet or dry systems.Due to the shortage of space and availability of land in informal settlements this system operates the best under these conditions (Lemer, 1996). Off-site sanitation This type of sanitation system transports sewage through sewer pipes using water. An off-site sanitation system only transport faecal matter away from households and does not include on-site decomposition to a significant degree. This type of system depends largely on the topography of the area and the planning around the system. There must be enough land and space before such a system is created, which is difficult in informal settlements.The cost of such a system is quite high (Scandura and Sobsey, 1997 ). The availability of funds and the topography play an important role in the decision making on what type of technology communities should have within informal settlements. Sanitation Guidelines for End-user Greater user acceptance is achieved through user involvement and influence in selection, implementation and management including operation of the technology is borne out of understanding and experience that people best understand their own development situation, social, cultural and religious practices.If the communities are involved it leads to greater ownership and empowerment and would translate into greater acceptance of responsibility and hence the technology. It is within the human nature to be more receptive and supportive when asked about one’s opinion as opposed to being dictated or told to what’s is best for oneself (Mara, 1996). Note the following reasons why services fail: †¢Ineffective planning, monitoring, evaluation and interventions †¢Poo r technical capacity to implement †¢Hygiene and inappropriate use practises. †¢Low user acceptance and satisfaction †¢Inadequate community involvement Low priority and †¢Lack of responsibilities between municipal, community and household Finally- it is of great importance not to move too fast from temporary programmes to full-scale programmes, the community need to receive the programme so that it is not rejected. Planning and Design for Sanitation by Local Authorities Sanitation technology is adequately dependent on the appropriate design specification is borne out of the understanding that the correct design standards and locally appropriate materials would enhance the durability of the technology in a given local context.Planning plays a pivotal role as it is used as an important factor to determine whether appropriate and sustainable sanitation technologies are achieved. A planning model that integrates everyone is ideal (WSP, 2007) that takes place within th e Integrated Development Planning (IDP) process (DWAF, 2001). The various sanitation options are demonstrated through the IDP process. A top-down to bottom-up approach for a planning model should drive the demand and should be entirely people centred, best achieved through a collective model (Tilley, 2008). Implementation process during planningA methodology for the provision of sanitation is necessary to establish sanitation for low-income settlements and to support and equip personal responsible for provision of sanitation to low-income settlements (Muanda, 2010). In the planning process specific emphasis for adequate functioning of the technology is placed on the environmental aspect, that local environmental and geological condition are considered and that the technology does not adversely impact on the environment (DWAF, undated). The recurring points that need to be systemised are as follows; Human rights and socio-cultural needs should be considered †¢Affordability for t he user †¢Sanitation should be demand driven †¢Stakeholder participation †¢Support, regulation and implementation within the community participation framework should be considered. †¢Provision for construction should be to locals. †¢Community linkage at all levels During the implementation place it is important to include health and hygiene training as to ensure improved health and hygiene practice (Still et. al, 2009). What happens in the case where a local authority has provided such training?Over time many new comers arrive into the settlement (as is the case in many informal settlements)? The only solution to the question here is to train trainers in the community who will be responsible for constantly creating awareness in their community (DWAF, 2009). Sanitation Provision Policy South Africa despite being a democratic country for more than a decade, with a sound constitution and sound policies there is still high levels of poverty and inequalities and budgetary realignments designed to address the legacies of the past and steady economic growth (DWAF, undated).Some policies have been relatively successful but still South Africa has the second highest in equality in the world behind Brazil (UNICEF, 2000). The fact is that by 1996 not that much had been achieved by way of sanitation provision in any of the provinces (DBSA, 2009). Sanitation has become a high priority on the development agenda, and not just with the Water Supply and Sanitation (WSS) sector specialist. The opportunities for financial support are better than ever, the political commitment is there, so as to deliver sustainable sanitation services to more than two billion people by 2015.A further 1,089 million rural and 1,085 million urban dwellers will need to gain access in the coming 15 years if the 2015 target is to be achieved. The first democratic government since 1994 has put in place policies that address the apartheid health legacy of racial discrimination. Du ring this process, several key-pro equity policies were inherited in the public sector. In the South African context the policy not only influences the approach to the financing and management of projects but also their technical features (WHO, 1999). CostsSocio-cultural landscapes and local variations in the physical landscape necessitate local input into the selection process and any preconceived ideas should be put on hold. Discussions with the targeted community about local capital and operation and maintenance costs have to be determined in each case that will enable the community and local authorities to come to a decision based on affordability. It is important that agencies reporting comparative costs on a wholly transparent basis, so that only the â€Å"true† basic costs of sanitation arrangement are presented to the communities (DBSA, 2009).Cost on various levels There are five (5) principles for various levels. †¢All costs relating to the provision of sanitati on service should be included †¢A distinction should be made between capital and operating costs †¢A clear distinction has to be made between internal and bulk services †¢Costs services must be expressed as current replacement at capacity cost. †¢Costs to be reduced per area or site. Cost sanitation technologies can also be influenced through the natural features such as vegetation, terrain and water availability and climatic conditions generally within the settlements.Conclusion The sanitation approach includes the perception, feel and practices involved in satisfying the primal need to defecate and urinate. Societal sanitation approach determines the nature of sanitation which serves as the crucial link between an unhealthy and healthy living environment. The term sanitation includes the safe disposal of domestic waste. For the purposes of this research, the structure seeks to understand the appropriate sanitation and identify a sanitation structure that is cos t effective and will be sustainable in informal settlements.Sanitation facilities are used to improve human dignity regardless of the area and the circumstances of the people. In this study we have looked at the process that needs to be followed in order to have sanitation technologies that safe guard the people. In informal settlements due to the nature of their existence and the lack of formal services, the communities usually do not take ownership of these facilities. The onus is upon government to train people about the importance of sanitation. The study focussed mostly on technologies that are used internationally and locally.The comparison of this technologies will be based on cost, structural intact and the maintenance therefore of the technology.

Research methodology This chapter provides a comprehensive description of the comparison methods used to analyse sanitation technologies in informal settlements (IS). It outlines an overview of the research design, data collection, research equipment and research methodology used in order to meet the study objectives. Research design This section of the study is made up of the following: * Li terature review which compromises of literature, a body review, a framework, a body of knowledge with regards to sanitation technologies. Data collection which compromise methods used to collect required data * Data Analysis and Presentation in the light of the literature review to determine the trends used for sanitation technologies for IS. Research methodology This study intends to provide a better understanding of sanitation facilities within the Western Cape within informal settlements and to compare the cost implications of such facilities. Data The data required in order to archive the study objectives includes the type of sanitation technology for IS and the cost in relation to sanitation technology.Data acquired was based on the following: †¢Type of sanitation †¢Cost (Operational & Maintenance) †¢Cost (Infrastructure) †¢Advantages and Disadvantages of On-site sanitation †¢Advantages and Disadvantages of Off-site sanitation Data Collection In order t o collect data two methods are used (Two interviews & Site visits). * Site visits on selected IS in order to assess the type of sanitation technology being used. The site visits where done by conducting visual assessment in three informal settlements with the Metro. Data was collected by comparing the types of technology that is being used within each settlement.A questionnaire template was used to gather user’s views and opinions on the technologies offered by the municipality. * An interview with the Municipal Officer (MO) to confirm or validate data/technology on site and the cost of the technology. The interview was set out to ascertain the magnitude and the need of sanitation facilities within informal settlements which is done by the municipality. Operational and maintenance cost of the technology being used was collected for comparison purposes. * An interview with manufactures of sanitation technologies was conducted in order to confirm cost per unit.All the manufactu res that where contacted where primary manufactures that the municipality procures all their sanitation technologies. Rocla was one of the manufactures that was interviewed about their precast toilets. Rocla has two sets of precast toilets one with sanitation facilities and one without sanitation facilities. A comparison of the two technologies has been tabled in Chapter 4. Santec was also interviewed about their Mobile toilets which comprised two sets of toilets (dry & wet). A comparison of the two technologies is outlined in Chapter 4.Research Equipment The following equipment was used for this study: * Pen; this tool was used to capture raw data from site. * Laptop; ; the laptop is used to store all data collected and is also used to make tables to present all the research work into a document * Digital Camera; the digital camera was used to take pictures on site and during interviews. * Mobile phone; mobile phones where used as a means of communication amongst all stakeholders i nvolved. * Fax Machine; was used to send and also receive data from stakeholders without email facilities and scans. Landline; the tool was used for communication between office hours and is the most affordable means of communication. Methodology Objective 1 – To investigate available sanitation technologies provided to informal settlement from operational, design, maintenance and cost. The objective was implemented by conducting of site visits, during which visual assessments where used to compile the name of the technology, specific technical aspects such as design and the condition of the technologies on site. Below is a list of design technologies within informal settlements that where visited. * Porta potiies * Chemical toilets Container toilets * Conservancy tanks * Pour flush toilets * Pit latrines * Urine diversion toilets * MobiSan toilets * Environmental loo Objective 2 * To classify the types of sanitation according to the characteristics (dry or wet sanitation; in dividual or communal). Classification of the technology was done by identifying individual and communal sanitation technologies. * * Dry sanitation | * Wet sanitation| * A dry toilet differs from a flush toilet (water closet) in that it does not need water. Excreta are collected directly beneath the seat in a shallow pit, container, chamber, such as the bucket system.Confusion must cleared between the systems especially latrine system which is constructed on a deep pit. Dry toilets ranges include a squatting plate or pedestal, with a smooth finished surface and is often utilised in limited area to minimise soiling. | * These are the conventional full flush system with sewers and waste water treatment plants, full flush systems with septic tank and small bore sewers, and the full flush systems with shallow sewerage. With septic tanks will significantly reduce operating costs, while the third system shallow sewers will significantly reduce the capital costs.The advantages of this grou p of toilets are that they operate as full flush toilets, can accommodate grey water disposal, and are well suited to densely populated areas where the plot sizes are insufficient to treat and drain household wastes. | * Objective 3 – Selection of the suitable option The suitable option was based on the advantages and disadvantages on the interview and the cost of the technology by the manufacture. The selected option is also based on the manufacture’s specification which used on site by the municipality and the budget allocated to the MO for that particular region.Advantages of On-site sanitation| Disadvantages of On-site sanitation| The system must be simple to construct, operate and maintain| This system is not suitable for substrata with hard rock and high water table conditions. | Installation should be less expensive and maintenance the same| The is a high possibility of pathogens contaminating the groundwater| Pollution of water surface should be eliminated| In highly densely populated urban areas such as informal settlements crucial groundwater resources can get contaminated. | Semi Structured InterviewsSemi structured interviews were conducted to collect data from users to obtain the users views on sanitation technologies and the type of service the municipality is rendering. Users were asked questions on sanitation situations, technology selection, performance of facilities, appropriateness of the technologies, operational and maintenance of the facilities. A total of twelve (12) interviews were conducted. See (Appendix A) for the questionnaire template. Table 1 shows the distribution of the interviews conducted. Area| No. of interviews| Gugulethu| 4| Khayelitsha| 4| Nyanga| 4|TOTAL| 12| Table 1Distribution of interviews The questionnaires were administered on site with the users of the selected informal settlements. Administration of questionnaires was conducted in Xhosa since most of the users were comfortable speaking the language. D ue to the lack of finding suitable donor’s to fund our survey only small sample was administered that actually uses the facilities. Discussion This section of study reflects the visual assessment that was conducted on site. A questioner was used to ascertain the level of service from the end user on the three (3) identified sites.A comparison of technologies that is being offered in informal settlements by the municipality is also reflected. The physical structure of the technologies being offered by manufactures to municipalities. Operational and maintenance cost implication from the manufacture and that cost is later transferred or felt by the municipality.

Excreta are collected directly beneath the seat in a shallow pit, container, chamber, such as the bucket system. Confusion must cleared between the systems especially latrine system which is constructed on a deep pit. Dry toilets ranges include a squatting plate or pedestal, with a smooth finished surface and is often utilised in limited area to minimise soiling.ADVANTAGES| COST| DISADVANTAGES| No water required for flushing| Capital: R2000 – R 3500. 00 which can increase where soils not suited to drainage. | The toilet has to be cleaned without using much water. | Easy to construct with local material| Operating: R150 – R300 per annum where subsoil drainage is available| Collected excreta has to be carefully handled, excreta contains pathogens| May be used indoors| | Excreta have to be removed frequently to avoid smells, especially if the toilets are indoors| MobiSan (Mobile Sanitation)Mobi San (Mobile Sanitation) system in many ways has many advantages over existing dry systems. Below is a list of those advantages; MobiSan Advantages| MobiSan Disadvantages| The MobiSan system is an independent and self-contained system and has been proven that the system does not affect ground water at all. Faeces and urine are stored separately in the MobiSan. Urine is channelled away and the faeces fall into a ventilated chamber. The construction of the system is such that a handle on the outside of the cabin allows the solid waste to be stirred.The steering speeds up the drying of the excrement. The excrement is then channelled into a second component where this drying process is repeated again. The end product is dried up, it is pathogen-free manure that can be safely used to fertilise local vegetable gardens within the communities in informal settlements. This system lends itself as a more aesthetic and hygienic option for residents in informal settlements. | The technology provi ded is prone to vandalism and becomes full within a short period. Operating costs are very high. | Conservancy tank ADVANTAGES| COST| DISADVANTAGES|Waste is flushed into the tank where it is contained in isolation from the surrounding environment. | Capital: R2000 – R 5000. 00 depending on top structure and tank volume| Becomes full if domestic wastewater levels are high. | Easy to construct with local material| Operating: R 550. 00 per household and emptying cost estimated at R181 per tank. The tank is emptied on average 3 times per year| Emptying cost over the lifespan of the technology is quite high. | VIP (Ventilated Improved Pit) ADVANTAGES| COST| DISADVANTAGES| Applicable in rock terrain| Capital: R2500 – R 4500. 0Depending on householder input. | . Collected excreta has to be carefully handled, excreta contains pathogens| Does not require deep excavation| Operating: R35 – R135 every 2 years. | Prone to smells. | On-site Sanitation On-site sanitation has c ertain requirements, which need to be investigated before adopting the system. †¢The system must have adequate space for locating toilets and leach pits. †¢The designated site must have porous subsoil to absorb liquid content of excreta and †¢The groundwater depth should be greater than 1,5m from ground level.ADVANTAGES OF On-site sanitation| DISADVANTAGES OF On-site sanitation| The system must be simple to construct, operate and maintain| This system is not suitable for substrata with hard rock and high water table conditions. | Installation should be less expensive and maintenance the same| The is a high possibility of pathogens contaminating the groundwater| Pollution of water surface should be eliminated| In highly densely populated urban areas such as informal settlements crucial groundwater resources can get contaminated. | Pour flush slabs Pour flush slabs (squatting pans) are designed with a U-shaped facility which s partly filled with water under slab. The de sign which is U overcomes problems such as flies, mosquitoes’ and odour by serving as a water seal. After usage, excreta are manually flushed by pouring water into the pan with a scoop. The amount is about 1 to 4 litres of water which is required for each flush. The amount of water depends mainly on the design of the facility and the U-trap. This type of toilet can be made from plastic and ceramic, or from galvanized sheet metal . ADVANTAGES| COST| DISADVANTAGES| High level of convenience for the user| Capital: R 2000- R 3500 which can increase where soils are not well suited to drainage. Blockages occur a lot within these systems| The design reduces the need to handle fresh excreta. | Operating: R 150 – R 300 per annum where subsoil drainage is available| Requires small amounts of water for flushing| Can be used indoors| | Limited emptying service. | Communal or shared technologies In areas where there is not enough space, the sharing of latrines between several famil ies is a useful solution. The common situation is where groups of households or small communal areas have latrines to be used by all the families.The ownership of the latrines generally belongs to one of the houses, the owner of all the houses, or else ownership is shared between the households. The costs of pit emptying and other repairs is often included in the rent, causing problems when the owner does not live there, or the residents must collaborate to clean the latrine and collect money to get it emptied when necessary. This is a very widespread practice. Communal of blocks of latrines are located in a public area,
