This study explores views behind the failure of water supply projects to achieve sustainability, primarily from the 'users' perspective, and at a secondary level from the perspective of the government/funders. One completed water supply project was selected as a case study for the research project. The overriding principle behind the water infrastructure delivery programme is that the service must be provided in a sustainable manner, and that the community must actively participate and be involved in all the phases of the project. The provision of water is not simply as it might look. In reality it is a complex process, which involves a number of organisations with different, yet important roles and responsibilities. Ongoing collaboration is important among these organisations if the service is to be provided efficiently and in a sustainable manner. In particular, local government has a Constitutional obligation to provide services to all consumers in an efficient, affordable, economical and sustainable manner. The National and Provincial governments, however, have a number of responsibilities in the field of water services. Semi-structured interview method was used to collect data from respondents. Two sets of interview schedules were developed, one for the community/water project committee members, and the other for the government officials. The data collected was analysed both qualitatively and quantitatively. This analysis enabled the researcher to draw findings, make conclusions and propose recommendations. The findings and conclusions of the study point to lack of clarity on roles and responsibilities; gender and cultural constraints; and, poor training and capacity and building of the community as being some of the reasons for the failure of the project. The recommendations proposed entail, inter alia, massive community mobilisation and awareness creation programmes; improvement in levels of the service; adoption of a gender-sensitive approach to project development; and, implementation of a training and capacity building process in the community in order to 'revitalise' the project. The study has merely focussed on one water project and sets the scene for further exploration of the subject. It certainly highlights some critical issues around sustainability of water projects, and hopefully will contribute towards the ongoing debate in this area.

D. Tech. (Department of Civil Engineering and Building, Faculty of Engineering and Technology), Vaal University of Technology / Growing demand for water due to increasing populations, industrialisation and water consuming lifestyles puts stress on existing water supply systems. To cater for the rising demand, water distribution networks are expanded beyond their design capacities and this creates transient “low-pressure-open-channel flow” (LPOCF) conditions. Current water supply models use “demand driven approach” (DDA) methodology which is not able to simulate transient LPOCF conditions, that poses an impediment to management/analysis of pressure-deficient networks. With a case study of the water supply network of Kampala City, LPOCF conditions were studied in this research. A “pressure/head driven approach” (PDA/HDA) was used in order to determine what demand is enabled by particular nodal pressures. Conversion of free surface to pressurised flow was analysed and modelled, with a view to clearly understanding occurrence of this phenomenon. The research demonstrated that if adequate pressures and flows are to be maintained, effectiveness of the water distribution network should be given as much attention as water production capacity. The research also indicated that when network pressures are low, the head-driven approach to water distribution modelling gives more accurate results than the traditional demand-driven methodology. Coexistence of free-surface and pressurised flow in networks prone to LPOCF conditions was confirmed and modelled. Results obtained highlighted the advantages of developing fully dynamic and transient models in the solution of transient LPOCF conditions in water distribution networks. Models developed allow application of PDA/HDA and DDA methodologies in systems that may exhibit LPOCF conditions thus enabling identification, understanding and analysis of the status of all sections of the network. These culminated in the development of a DSS to guide operational decisions that can be made to optimise network performance.

A research report submitted to the Faculty of Humanities, University of Witwatersrand, Johannesburg in partial fulfilment of the requirements for the degree of Master of Arts in Development Studies March 2015 / The research report presents an analysis to, responses to and dynamics around the municipal water problems in Harare, Zimbabwe using the case of two residential suburbs namely Mabvuku and Greendale (one high density and the other one low density respectively). The key questions that inform this research report are as follows: How has the on-going urban water crisis affected residents‟ lives in the suburbs of Greendale and Mabvuku in the city of Harare, Zimbabwe?; how does party politics affect the delivery of municipal water in Greendale and Mabvuku?; and, what are the environmental consequences of the municipal water crisis? The findings from this study contribute immensely to an understanding of the consequences of and various issues and, the key players underlying the protracted problem of municipal water availability in the city of Harare. The study argues that the prevalence of partisan politics and political power struggles in Harare are at the heart of the municipal water problems faced by Mabvuku and Greendale. In this regard, the study critically interrogates the relationship between the central ZANU–PF government and Movement for Democratic Change (MDC)-led local government and tries to understand the ramifications it is having on municipal water services. Interestingly the study also reveals that, despite the differences in coping strategies by residents of Mabvuku and Greendale, both locales have not been passive victims of the municipal water crisis. Instead, residents from both suburbs employ strategies according to their needs to ensure survival. However, despite some of the coping strategies (such as borehole and well drilling) significantly helping residents to manage and avert the water stress in light of the absence of municipal tap water, the study presents, explores and discusses the environmental consequences that are likely to happen as a result of the high concentration of these alternative water sources. / GR2017

A project report submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science in Engineerrng, / As has happened throughout the world. environmental and water quality problems related to developing urban and industrial areas and associated accumulation of waste in built-up areas were the main factors in contributing to sanitary awareness in South Africa. The dwindling water resources and persistent deterioration of water quality, more severely in urban areas, necessitates the review the current practice of storm water management in South Africa. Reliable stormwater drainage models evaluating both the water quantity and quality could be essential in confronting the prevailing pollution problems. The objective of this project was conceived to be the development of a system for the simulation of water quality in urban watercourses, A personal computer compatible model for joint transportation of hydrograph and pollutographs in open channels was developed. The model comprises an operational data handling facility, a user friendly and interactive interface. The study revealed that: Urban and Industrial development results in complication of the urban water system. • Single objectivity approaches in management of urban watercourses are outdated . .. The proposed model is capable of simultaneously routing flood and pollutant condiment waves in open channels. Understanding of aspects of the water quality in urban watercourse can be greatly enhanced by the proposed model. The following recommendations were henceforth made: • Detailed study of the nature. quantity and sources of pollutants in the urban water system. .. Sophisticated (dynamic wave. supercritical flow, complicated ..................... hydrodynamic model snould be considered, • Biological and, chemical process in the urban watercourse be incorporated. • Linking of the water quality model to the storm water drainage model, / Andrew Chakane 2018

Water is essential for life, and access to sources of safe water and sanitation facilities is a first-order concern for economic welfare and general well-being. While the majority of residents in developing countries have access to improved water and sanitation services, many parts of the developing world lag significantly behind in this vital infrastructure. This dissertation studies policies aimed at increasing access, quality, and efficiency of improved water and sanitation (WS) services in developing countries. In the following three chapters, I focus on non-technological methods for improving service by eliminating the economic, political, and institutional barriers to safe water and sanitation provision. Chapter 1, “The Buck Stops Where? Federalism and Investment in the Brazilian Water and Sanitation Sector”, shows how weak institutions can undermine public goods service when multiple levels of government share responsibility of provision. In particular, I study how legal ambiguities regarding degrees of governmental authority can lead to systematic underinvestment in public utilities. I examine the Brazilian water and sanitation (WS) sector, which presents an natural experiment of shared provision between state and municipality entities. I look at a legal reform that clarified the relationship between municipalities and states in a quasi-experimental, difference-in-differences framework, using an administrative, municipality-level panel dataset from 2001-2012. I find that when expropriation risk by state companies diminished - self-run municipalities almost doubled their WS network investment. This increase in investment led to a significant increase in access to the WS system in these municipalities. The analysis provides strong evidence that reforms that strengthen residual control rights and eliminate the threat of intra-governmental expropriation can lead to large increases in public goods investment. Chapter 2, “The Role of Basic Sanitation Plans on Service Provision: Evidence from Brazil”, investigates non-technological methods of increasing access to improved water and sanitation (WS) in developing countries. In particular, it presents evidence of the efficiency gains that can be achieved in municipal water provision through the act of formulating and carrying out basic sanitation plans. I exploit the staggered roll-out in implementation of basic sanitation plans throughout municipalities in southern Brazil from 2007-2013. I find that, in the three years after the enactment of sanitation plans, municipalities increased the efficiency of their respective water systems through the tightening up of “leakages" in the system, both in terms of water distribution and bill payment. However, I find no significant increases in the degree of individual access to the systems, suggesting that in the relatively short-run, providers focus on improving the existing system as opposed to building out new infrastructure. Chapter 3, “(Not So) Gently Down The Stream: River Pollution and Health in Indonesia”, addresses the fact that waterborne diseases are the leading cause of mortality in developing countries. We emphasize a previously ignored cause of diarrhea - upstream river bathing. Using newly constructed data on upstream-downstream hydrological linkages along with village census panel data in Indonesia, we find that upstream river bathing can explain as many as 7.5% of all diarrheal deaths. Our results, which are net of avoidance behavior, show no effect of trash disposal on diarrheal infections. Furthermore we find that individuals engage in avoidance behavior in response to trash disposal (visible pollutants) but not river bathing (invisible pollutants). We conduct policy simulations to show that targeting upstream individuals could generate substantial environmental and health savings relative to targeting downstream individuals. This provides a potential road map for low- and middle-income countries with limited resources for enforcement of water pollution.

Thesis (MBA.) -- University of Limpopo, 2007 / The residents of Lebowakgomo in Lepelle-Nkumpi Municipality experience numerous inequalities in relation to water services provision. Some of the residents protest towards the inequalities through refusal to pay for the water services. The confrontational non paying residents field questions which the municipality can hardly answer. The problem of refusal to pay is of the magnitude that recently the municipality had to go house-to-house pleading with the inhabitants to pay if the municipality was to continue to provide water services. The specific objectives of this study were three-fold: (1) to determine water service quality using residents’ perceptions on water services in Lebowakgomo, (2) to determine residents’ expectations and perceptions on water services in Lebowakgomo, and (3) to determine the residents’ perceptions on water service quality and customer satisfaction in Lebowakgomo using age, gender, qualification and suburb. A questionnaire comprising five dimensions, namely, tangibles, reliability, assurance, empathy and responsiveness, was compiled to collect data from three suburbs of Lebowakgomo in Lepelle-Nkumpi Municipality. The original sample size was 120, with 9 becoming spoiled due to missing data. The independent variables comprised age, qualification, suburb and gender. Most of the data were analysed for kurtosis and skewness and with the exception of one variable, the rest of the data did not conform to parametric analysis criteria. The major findings of this study indicated overall negative perceptions of residents’ on four dimensions of empathy, reliability, responsiveness and assurance on water service quality which implied that the residents were dissatisfied with the service and called on management to use SERVQUAL as a valid model of assessment to identify areas requiring immediate attention for service improvement. On the other contra positive it was revealed that the municipality was doing well on the tangibles dimension. ix The study recommended use of SERVQUAL in measuring quality of other services within the constitutional competencies of the municipality and further research to investigate age contribution to service quality.
