Thesis (M. Dev. (Planning and Management)) -- University of Limpopo, 2019 / The provision of basic water services delivery to all South African citizens is one of the huge challenges for the local government and it is at the coalface of service delivery. The objective of the study was to determine the factors that influence water service delivery challenges in the local municipality of Makhuduthamaga, in Sekhukhune District Municipality. The statement of the problem, therefore, provided the foundation within which the aims of the study are explained. The significance of this research cannot be over-emphasised, especially against the backdrop that local government is the third sphere of government and is in the front line of service delivery. This study aimed at investigating the water service delivery challenges in the municipality of Makhuduthamaga in Sekhukhune District, Limpopo province. This research was necessitated by the lack of water in Makhuduthamaga Local Municipality. It is evident that there are several challenges in the delivery of water services in the local sphere, however, for the sake of this research only one municipality was selected as a case study. The study employed a qualitative case study research design to collect data from participants who were selected through a purposive sampling technique. The study participants included the local community representatives and the municipal officials responsible for water services in the municipality and the water resources available in the locality such as the Vergelegen, Nkadimeng and De Hoop dams. The finding shows that the available water sources are not adequate to cater for all the residents of the municipality; hence this affects the water delivery efforts of the municipality significantly. As a result, local residents have expressed their dissatisfaction through violent service delivery protests in different wards of the municipality. The study further reveals that the municipality has been facing serious water services challenges over several years. The issue emanates from the water sources which are dried up, illegal connections, incomplete projects by contractors, financial constraints, and poor maintenance planning. The main challenge here is the lack of water sources, poor maintenance, lack of skills and expertise from the employees in the water department, insufficient budget to relieve the water crisis in the municipality and the district at large. The municipality has implemented all the interventions, such as public participation to vi encourage communities to use water sparingly, to pay for services of the municipality for the sake of revenue enhancement and have drilled more boreholes to augment the water services to the communities. This study recommends that the municipality should prioritise their budgeting and align this to the community needs, hiring the correct personnel with relevant skills and expertise in the water related function. Also, the municipality needs to work on the turnaround time for the maintenance of pump stations and fixing of leaking water pipes. They should penalise all the illegally connected households so that they can curb all the recurring illegal connections. The other issue is to improve communications with the communities with relevant stakeholders to ensure that everyone is informed in case of water cuts due to maintenance or cleaning of water reservoirs.

Thesis (M. Sc. (Geography)) -- University of Limpopo, 2021 / In South Africa, inadequate water supply is currently a national crisis hence, referred to as a water stressed country. The study’s aim was to assess water supply constraints in Giyani Township of the Greater Giyani Local Municipality that falls under the Mopani District Municipality. The Constitution of the country recognises water as a constitutional right. However, many households in Giyani Township do not receive regular water supply. In some communities, water infrastructure is available but not frequently maintained and that led to irregularity in water supply. The study used qualitative and quantitative research approaches. Self-administered structured questionnaire that consisted of open-ended and close-ended questions helped to collect primary data from the 382 sampled respondents of Giyani Township. Key Informants Interview (interview of people who are authorities responsible for water supply services) supplied information with regard to water delivery services in Giyani Township. Observation method assisted in the evaluation of the condition of the water supply infrastructures as well as the availability of water on a daily basis. Findings of the study indicated that most residents relied on piped water from Giyani Local Municipality, although water was not always readily available from the municipality. Incorrect billing for water services and delays in completion of water relief projects in addition to natural causes and lack of skilled workers were some of the causes that affected the regular supply of water in the township. The study concluded that Greater Giyani Local Municipality experienced a problem of water service delivery that impact negatively on communities and development as a whole The study recommended that the community should voice out grievances about the irregular water supply and request for further clarifications from the municipality during community meetings.. Keywords: Water, water constraints, water supply, Greater Giyani Local Municipality.

Thesis (M.Sc. (Geography)) -- University of Limpopo, 2022 / Various studies have indicated problems of water pollution in South Africa, with some of them highlighting the high concentrations of chemical pollutants in the Loskop Dam. These reports show how pollution in the dam has affected aquatic life and poses a health risk. However, limited studies have been conducted on the impact of declining water quality on tourism in Loskop Dam. These studies focus more on the ecological aspect of the dam. Therefore, the main objective of the current study is to explore how tourism is affected by the declining water quality in Loskop Dam by examining the impacts of water pollution on the tourism sector linked to Loskop Dam and associated socio-economic effects. A questionnaire-based survey was conducted to collect information from small and medium-scale enterprises (SMEs) employees and freshwater tourists, and interviews were conducted with SME managers to get more information on tourism activities, water pollution in Loskop Dam, as well as information on the impacts of decreased water quality. The outcome is that a decrease in water quality affects tourism negatively, inclusive of recreational activities, business operations, and subsequently having a negative social and economic impact on Loskop visitors and employees. / National Research Foundation (NRF)

The research study focused on assessing the potential risk of failing to maintain water supply in the Rand Water area. The study analysed all factors and areas that contributes to water supply in the Rand Water area; this included municipalities supplied by Rand Water, the Department of Water Affairs and other factors that directly affect Rand Water supply such as population growth, increased urbanisation and acid mine drainage. The objectives of the study were: (a) is to determine the potential risk of failing to maintain supply in the Rand Water supply area, in other words, the likeliness of water not being supplied adequately to customers. (b) generate timely and credible information to determine the understanding, awareness, and acknowledgement by the sampled management group of the existence of the potential water supply risk in the Rand Water supply area. This will be done through a quantitative study. The research study approach that was utilized was a quantitative methodology; this approach included the distribution of questionnaires to all relevant stakeholders in the Rand Water supply area. To address the problems that are highlighted in the problem statement and achieve the objectives of the study these answered questionnaires were then sent to a Statistical consultant at North-West University‟s Potchefstroom Campus, to be analysed using an SPSS Version 21 statistical program. The questionnaires were divided into the three big municipal customers, these municipalities combined takes a total of 74.35% of Rand Water supply; these are Johannesburg Water which is part of the City of Johannesburg Metropolitan Municipality, Ekurhuleni Metropolitan Municipality, Tshwane Metropolitan Municipality and other small municipalities and the Department of Water Affairs‟ officials. Many previous studies also were assessed to be able to help this study establish the seriousness of the water challenge, the amount of work that has already been done, factors contributing to the problem and finally, measures that can be put in place to address the problem. The results that were obtained for this study provided many relationships between this study‟s selected variables and also highlighted the need to put certain strategies in place to be able to control the growing demand for water in the Rand Water system. The name of the Department of Water Affairs has changed many times over the year. It used to be called DWAF (Department of Water Affairs and Forestry, then DWEA (Department of Water and Environmental Affairs, then DWA (Department of Water Affairs) and it has recently been changed to DWS (Department of Water and Sanitation. For the purposes of this study this department will be called DWA (The Department of Water Affairs) The results were very relevant as most of the relationships were found between variables that are practically supposed to be related in order for the problem to be dealt with fruitfully. From these results it could be concluded that the risk of failing to maintain water supply in the Rand Water supply area does exist, if certain factors were allowed to trend the way they‟ve been trending without measures in place to counteract them. It could also be concluded that certain measures have been initiated to deal with the problem; this included water demand management. Results indicated that collective efforts from all stakeholders in the Rand Water supply area will be crucial in addressing the water supply challenge and avoid future failure to supply. To close the gap between previous research studies and this research study recommendations were made. Areas of future research were also highlighted; these are areas that can add value in providing valued information to help the challenge of water shortage in the Rand Water supply area. This area of future research studies will also be crucial in identifying other external factors that were not highlighted in the study but contribute to the problem. This area of future research studies will also help when implementing turnaround strategies to avoid the risk of failing to maintain supply in the Rand Water area as it will be able to highlight a different strategy that deals with the problem holistically. / MBA, North-West University, Potchefstroom Campus, 2015

Community-based approaches are of fundamental importance in the development of rural water supply and sanitation. Three case studies demonstrate that, by means of negotiation, need assessment, community participation, community-based management and appropriate technology, a reasonable degree of success can be achieved in providing an adequate and safe drinking water supply to most unserved communities. The research also shows that necessary negotiations with the government are often more complex and time-consuming than those with the community itself. Either the weight of bureaucratic processes or the lack of capacity and willingness on the part of the government to implement small-scale water projects using community-based approaches, were the reasons for the complexity of negotiations in one case study. It was also found that self-initiated projects with strong back-up support from development agencies are more successful than are projects initiated from outside. It was also noticed that community-based management is feasible and that it can lead to sustainable development. / Sociology / M.A (Social Science)

Submitted in fulfillment for the requirements of the degree of Master of Technology: Chemical Engineering,Durban University of Technology. Durban. South Africa, 2015. / Access to safe drinking water supply is still a major problem especially in remote rural areas of developing countries. These communities rely solely on untreated surface and ground waters for survival due to the lack of financial resources to provide access to piped water. The consumption of this water in turn makes them easily susceptible to water related diseases. Hence, there is a need for an interim solution while the government is still sourcing funds for the distribution of water to these communities. Membrane filtration is a promising technology for the treatment of surface water as it does not alter the taste or smell of the end product. The main limitation for the implementation of membrane technology in rural areas is still energy demand, fouling and the skills required for membrane cleaning. Biological ultrafiltration is an emerging technology that produces water of high quality in terms of turbidity, organics and bacteria removal. The technology has been evaluated using a gravity driven dead-end mode on European waters and it offered acceptable stabilisation of fluxes for extended periods without any chemical cleaning or backwashing. This is a promising technology which can be implemented to act as an interim solution for the treatment of surface water in remote rural areas prior to consumption. This study concerns the evaluation of a biological ultrafiltration membrane system on local three South African rivers, namely, Tugela River, Umbilo River and Umgeni River. A laboratory systems comprising of a feed tank and six membrane modules connected in parallel was set up to assess the performance of a bio-UF membrane on a range of surface waters. The performance was assessed on the system’s ability to produce stable fluxes from the three rivers, the system ability to produce water with acceptable quality in terms of SANS 241:2011 for turbidity, TOC, total coliforms and E-coli. The membranes were initial cleaned and the flux rates for ultra-pure water were determined for each membrane prior to being exposed to raw water. Raw water samples were collected from three rivers with varying turbidity, total coliforms and organics. The concentrations of these contaminants were tested prior to running the raw water through the system. Thereafter, permeate was collected with time and its quality was evaluated in terms of turbidity, TOC and coliforms. The impacts of algae on flux stabilisation were evaluated by allowing the bio-UF system to run for a minimum of 3 months with and without algae growth. The system was found to be able to produce water that is compliant with the SANS 241:2011 standard in terms of turbidity, total coliforms, E-coli and TOC concentration. The system was also found to be unable to produce stable fluxes for all three rivers. The observed responses were noted to be similar to normal dead-end response, however, a slow declining flux rates was observed for Umgeni River. The presence of algae during the operation was a bio-UF membrane system was noted to further decrease the rate of flux decline. There appears to be a correlation between the raw water quality and the rate of flux decline. A further investigation was carried out aimed at assessing the relationship between the concentration of bacterial counts, TOC and turbidity. From the obtained results, it was noted that feed water with low turbidity (≤ 5 NTU), high bacterial count (≥30 000) and high total organic carbon (≥70 mg/L) is able to reduce the rate of flux decline. Hence, it can be concluded that a dead-end gravity driven Bio-UF membrane system can be used for the treatment of surface water in remote where the most main contaminants are from natural organic matter, micro-organisms and turbidity. Furthermore, it is able to produce slower declining flux rates which will increase the filter run time. It is recommended that the impacts of algae, type of bacteria and organics that enable slow decline in flux rates during the operation of Bio-UF should be investigated in order to identify means of enhancing the flux rates. Microfiltration membranes are available on the local markets hence it is also recommended that the performance of Bio-UF should be evaluated in comparison to Bio-MF.
