An investigation of water supply constraints in Giyani Township, Greater Giyani Local Municipality, Mopani District, Limpopo Province

Ramadapa, Relebogile Mosibudi Sandra Sanaree January 2021 (has links)
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.

Monitoring and modelling of water quality characteristics along a reticulation system: a case study of modimolle reticulation network

Mehlo, Mahlomola 01 1900 (has links)
M. Tech. (Department of Civil Engineering and Building, Faculty of Engineering and Technology), Vaal University of Technology. / Potable water quality can deteriorate immensely from point of treatment to point of usage. This change in quality along a bulk distribution main may be attributed to numerous factors, such as the ingress of storm water. Furthermore, water utilities experience challenges in terms of the microbiological organisms that are not attributed to operational practices. For example, drinking water bulk distribution mains may be a shelter for these microorganisms that are sustained by organic and inorganic nutrients present within the pipe itself. These microorganisms may be active in the water being transported by the pipe, and can cause a significant drop in the water quality. In order to deal with the problem of deteriorating water quality, sufficient information within the bulk main is required, so that the consumer can be protected from ingesting contaminated water or water of poor quality. Hence, the overall objective of this study was to investigate and model water quality characteristics within the Modimolle reticulation network. Water samples were collected from various points throughout the entire system for quality analysis. Different sampling points were established along the main pipeline as well as within the Modimolle distribution system. Water quality software, EPANET, was then used to model the water quality deterioration for both the bulk line and the reticulation network of Modimolle extension 11. Residual chlorine was the main parameter which was monitored. This study presents results of a research on water quality variation within a long distribution mains conveying water up to 87 km. Results show that raw residual chlorine is constantly depleted along the pipeline, and is therefore unable to be maintained at the required level of 0.2 mg/l, as stipulated by the Department of Water Affairs. This means that if any harmful contaminants should enter the water, the residual chlorine in the water will not be able to protect the consumers from the contaminants.

An assessment of the impact of declining water quality on tourism : a case study of Loskop Dam, Mpumalanga, South Africa

Makwela, Tshegofatso Rahab January 2022 (has links)
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)

Investigating the causes and impact of infrequent water supply on the wellbeing of communities : a case Greater Tzaneen Municipality, Limpopo Province

Makhubela, Ordnance Jabu January 2022 (has links)
Thesis (MPA.) -- University of Limpopo, 2022 / The provision of clean water and water scarcity are the most critical impediments to sustainable development in municipal water supply. Adequate water supply and sanitation services are essential for health, economic development, and environmental protection. Recognizing the importance of access to a safe and adequate water supply has become the core business of many South African municipalities. Among the major challenges facing local government regarding basic service provision in South Africa are acute problems of institutional capacity, maintenance of existing infrastructure, mismanagement of funds, high levels of corruption, political interference and a lack of public anticipation. There has been public outcry in South Africa about poor performance of municipalities in service delivery. Moreover, a good proportion of service delivery protests relate to municipalities‟ “failure to carry out” the supply of “basic” services like water.” It is against this” backdrop “that the” aim of this “study” was “to investigate the” causes of” infrequent “water” supply “on the” wellbeing “of” communities “in” the Greater Tzaneen Municipality, “Limpopo province. Although local municipalities in South Africa are regarded as the providers of essential services, such as water, to date most of the municipalities still lack the capacity to provide water services to community members across the country.” Greater Tzaneen “Municipality finds it challenging to provide water services to communities within its jurisdiction. To achieve this objective, the researcher utilised a combination of qualitative and quantitative research methodologies with a semi”- structured “questionnaire. The” study finds that the municipality is a water service provider and not as such has no authority in the provision of water to the villages. Moreover, it is found that the infrequent water supply has negative impact on the wellbeing of communities’ as water is a basic need and without it, it deprives the citizens of their dignity as enshrined in “Chapter two of the Bill of Rights of the” South African “Constitution.”

Aspects of the economics of water management in urban settings in South Africa, with a focus on Cape Town

Jansen, Ada Isobel 03 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Concerns about the sufficiency of freshwater supplies and the impact of water shortages have placed sustainable water management on the global agenda. This is particularly relevant in South Africa, a country with precipitation rates well below the global average and water resources that have become highly polluted. The scarcity of water for consumption use and of unpolluted water bodies as recreational and environmental good highlights the need for an economic analysis of these issues. This dissertation investigates some economic aspects of water management in the South African context in two distinctive parts. Part One (Chapters 2 to 5) aims to provide an understanding of urban water demand and analyses water pricing as demand management tool. Part Two (Chapters 6 and 7) analyses the values people attach to water resources for recreational and environmental purposes. Quantitative methodological approaches are predominantly used to inform an economic perspective on water demand management. The extent of water scarcity is discussed in Chapter Two. South Africa is approaching physical water scarcity, but many poor households do not yet have access to water and basic sanitation facilities, i.e. there is also economic water scarcity. Given this background, Chapter Three focuses on water demand management as part of an integrated water management approach. The role of water prices is discussed, in particular the Increasing Block Tariff (IBT) structure which is predominantly used in South Africa. Chapter Four estimates the price elasticity of demand for water using household water consumption records obtained from the City of Cape Town (CCT). A distinctive feature of this case study is a survey undertaken to collect household information on demographic and water-use characteristics, as water databases are severely lacking in South Africa. The results show water demand to be mostly price inelastic, which concurs with findings from international empirical literature. Furthermore, higher-income households are found to be more sensitive to price changes, thus some reduction in water consumption can be achieved by increasing marginal prices at the upper end of the IBT structure. Chapter Five analyses the IBT structure as a redistributive tool. Particular attention is given to the Free Basic Water policy of South Africa, which allows each household to receive six kilolitres of water free per month. Empirical modelling indicates that the IBT structure in its current form holds limited benefits for the poor, given the state of service delivery in South Africa: the lack of access to the water network prevents the poorest households from being the recipients of the cross-subsidisation occurring in an IBT structure. Part Two studies urban water resources as recreational and environmental goods. The literature review of environmental valuation techniques in Chapter Six places particular emphasis on the Contingent Valuation Method. This method is applied in Chapter Seven, where the value of improving the environmental quality of a freshwater urban lake is analysed in a middle- to low-income urban area. Another survey was undertaken specifically for this purpose of gauging the willingness to pay for improved recreational facilities and water quality of Zeekoevlei. The results show that low-income households do attach value to urban environmental goods, a result which adds to our knowledge of willingness to pay for environmental goods in developing countries. / AFRIKAANSE OPSOMMING: Besorgdheid oor die toereikenheid van varswaterbronne en die impak van watertekorte het volhoubare waterbestuur op die wêreldagenda geplaas. Dit is veral relevant vir Suid- Afrika, 'n land met neerslagkoerse ver onder die wêreld gemiddelde en waterbronne wat hoogs besoedeld geword het. Die skaarsheid van water vir verbruik en van onbesoedelde waterbronne as ontspannings- en omgewingsproduk, beklemtoon die noodsaaklikheid vir 'n ekonomiese analise van hierdie kwessies. Hierdie proefskrif ondersoek sekere ekonomiese aspekte van waterbestuur in die Suid-Afrikaanse konteks, in twee dele. Deel Een (Hoofstukke Twee tot Vyf) beoog om insig te verskaf oor die stedelike vraag na water en analiseer die prys van water as 'n vraagbestuursmaatstaf. Deel Twee (Hoofstukke Ses en Sewe) ontleed die waarde wat mense heg aan waterbronne vir ontspannings- en omgewingsdoeleindes. Kwantitatiewe metodologiese benaderinge word hoofsaaklik gebruik om 'n ekonomiese perspektief op watervraag bestuur toe te lig. Die omvang van waterskaarsheid in Suid-Afrika word in Hoofstuk Twee bespreek. Hierdie hoofstuk dui aan dat Suid-Afrika besig is om fisiese waterskaarste te bereik, maar die land het ook baie arm huishoudings wat nog nie toegang tot water en basiese sanitasiefasiliteite het nie, dw.s. wat daar is ook ekonomiese waterskaarsheid. Gegewe hierdie agtergrond, fokus Hoofstuk Drie op watervraagbestuur, as deel van 'n geïntegreerde waterbestuursbenadering. Die rol van waterpryse word bespreek, veral die Stygende-Blok-Tarief (SBT) struktuur wat grotendeels in Suid-Afrika gebruik word. Hoofstuk Vier bepaal die pryselastisiteit van vraag vir water met behulp van huishoudelike waterverbruiksdata, verkry vanaf die Stad Kaapstad. 'n Kenmerkende eienskap van hierdie gevallestudie is die ingesamelde huishoudelike inligting oor demografiese en waterverbruik-eienskappe, aangesien daar ‘n groot tekort aan water-databasisse in Suid- Afrika is. Die uitslae toon dat watervraag meestal prysonelasties is, wat ooreenstem met bevindinge van ander empiriese literatuur. Verder word gevind dat hoё-inkomste huishoudings meer sensitief is vir prysveranderinge. Dus sal 'n afname in waterverbruik bewerkstellig kan word deur marginale pryse aan die hoёr kant van die SBT struktuur te verhoog. Hoofstuk Vyf ondersoek die SBT struktuur as 'n effektiewe herverdelingsmaatstaf. Spesifieke aandag word aan die Gratis Basiese Water-beleid van Suid-Afrika geskenk, wat voorsiening maak dat elke huishouding ses kiloliter water per maand verniet ontvang. Die bevindinge van empiriese modellering is dat die SBT struktuur, soos dit tans in Suid-Afrika toegepas word, beperkte voordele vir die armes inhou, gegewe die huidige stand van watervoorsiening in Suid-Afrika. As gevolg van die agterstand met betrekking tot toegang tot water, ontvang die heel armes nie die voordele van kruissubsidiёring wat plaasvind onder 'n SBT struktuur nie. Deel Twee bestudeer stedelike waterbronne as ontspannings- en omgewingsprodukte. Hoofstuk Ses verskaf 'n literatuur oorsig oor omgewingswaardasie tegnieke, met 'n spesieke fokus op die Kontingente Waardasie-metode. Hierdie metode word in Hoofstuk Sewe toegepas, waar die waarde van verbeteringe in die omgewingskwaliteit van 'n varswatermeer in 'n middel- tot lae-komste stedelike gebied ondersoek word. Nog 'n opname is gedoen met die doel om die bereidwilligheid om te betaal vir verbeterde ontspanningsfasiliteite en die waterkwaliteit van Zeekoevlei te meet. Die bevindinge toon dat lae-inkomste huishoudings wel waarde heg aan stedelike omgewingsprodukte.

An evaluation of the feasibility of obtaining payment for ecosystem services for the Baviaanskloof Nature Reserve

Erlank, Wayne Michael January 2011 (has links)
Cities must go further and further away to find new, more costly sources of water for human consumption while industries and agriculture continue to compete for increasingly scarce water resources. This may already be seen occurring within the Nelson Mandela Bay Metro where the severe drought being experienced during the past 18 months has severely depleted water supply dams. One of the main supply dams to the Nelson Mandela Bay Municipality is situated within the Baviaanskloof Nature Reserve and World Heritage Site. The potential of funding the Baviaanskloof Nature Reserve and World Heritage Site with payments for ecosystem services (water) obtained for water services supplied to the Nelson Mandela Bay Municipalities and agriculture in the Gamtoos River Valley will ensure financial sustainable for the Baviaanskloof Nature Reserve and World Heritage Site in the long term. This ability to become financially independent and generate its own income will place the Baviaanskloof Nature Reserve and World Heritage Site in a unique position within the conservation community in South Africa as only a very few protected areas are self sustaining through payment for an ecosystem service.

Aspekte van die openbare beleidproses in Suid-Afrika met spesiale verwysing na die waterbeleid (1994-1999)

Van Wyk, Jo-Ansie Karina 03 1900 (has links)
Thesis (MA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: This dissertation presents aspects of the public policy process in South Africa with specific reference to water policy between 1994 and 1999. For the purposes of this research, the definition of water policy coincides with the government's definition as contained in the Reconstruction and Development Programme (RDP), the Growth, Employment and Redistribution Programme (GEAR), white papers, bills and legislation. Water policy is a broad subject and is approached from a social sciences focus in this study, in that it uses the fulfilment of human needs as a point of departure. Water policy that applied before 1994 was based on water legislation of 1956, as well as some eighty different Acts that were fragmented between a number of institutions. The focus was on water rights, linked to property rights from which the majority of South Africans were excluded. In the implementation of policy attention was mainly paid to engineering achievements. The acknowledgement that water resources are limited in South Africa, as well as in the rest of the world, and the increasing demands on these sources, focused the attention anew on responsible water policy. Since South Africa's transition to an inclusive political democracy in 1994, a variety of far-reaching changes took place with regard to political decision-making and the public policy process. Not only did the policy-making process change, but policy goals, actors, structures and organisations also changed. It is clear that the policy agenda differs significantly from that of the period preceding 1994. In this study, the context within which policy renewal took place in South Africa since 1994, has been presented, and the policy process that new water legislation was subjected to, is described. The role of policy actors and communities - in line with the principles of the Constitution of 1996 that encourage public participation in the democracy - is considered. The implementation of the new water policy could unfortunately not be evaluated as it has only been promulgated a year ago. This study serves as an introduction to a research area which has received little attention thus far and that has potential for further research. / AFRIKAANSE OPSOMMING: In hierdie studie word aspekte van die openbare beleidproses in Suid-Afrika ondersoek met spesiale verwysing na waterbeleid tussen 1994 en 1999. Waterbeleid is vir die doeleindes van hierdie studie omskryf soos in die regering se HOP, GEAR, witskrifte, wetsontwerpe en wetgewing. Waterbeleid is 'n breë onderwerp wat in hierdie studie vanuit 'n sosiaal wetenskaplike hoek benader is, naamlik dat daar aan basiese menslike behoeftes voldoen moet word. Die waterbeleid wat voor 1994 gegeld het, was gebaseer op die Waterwet van 1956, asook wetgewing wat oor tagtig wette versprei was en deur 'n aantal instellings gefragmenteer is. Die klem het geval op waterregte, gekoppel aan eiendomsregte waarvan die grootste deel van die Suid-Afrikaanse bevolking uitgesluit was. Klem is ook gelê op ingenieursprestasies in die uitvoering van beleid. Die besef dat waterbronne wêreldwyd en in Suid-Afrika beperk is met toenemende aansprake wat daarop gemaak word, het opnuut die aandag op verantwoordelike waterbeleid gevestig. Sedert Suid-Afrika se oorgang na 'n inklusiewe politieke demokrasie in 1994 is verskeie verreikende veranderings ten opsigte van politieke besluitneming en die openbare beleidproses ingestel. Nie alleen het die beleidmakingsproses verander nie, maar beleidsdoelwitte, -akteurs, -strukture en -organisasies het ook verander. Kortom, die beleidagenda verskil van die periode voor 1994. In hierdie studie is die konteks van beleidvernuwing in Suid-Afrika na 1994 geskets, en die beleidproses waardeur nuwe waterwetgewing gegaan het, is beskryf. Die rol van beleidakteurs en -gemeenskappe - in lyn met die beginsels van die Grondwet van 1996 wat openbare deelneming aan die demokratiese bestel aanmoedig - is ondersoek. Die implementering van die nuwe waterbeleid kon egter nie geëvalueer word nie, aangesien dit skaars 'n jaar gelede gepromulgeer is. Hierdie studie dien as 'n inleiding tot 'n navorsingsveld wat steeds braak lê met moontlikhede vir verdere navorsing.

Principles for mainstreaming gender equality in the South African rural water services sector

Rust, Urszula Anna 12 1900 (has links)
Thesis (MPhil (Sustainable Development Planning and Management))--University of Stellenbosch, 2007. / Gender equality and access to basic water services are complexly interlinked objectives for both poverty alleviation and sustainable development. In South Africa, research shows that despite the emphasis on mainstreaming gender equality in the water services sector, (and the concomitant policies and structures) the lives of poor women in this sector are not substantively being transformed. This study was therefore aimed at deriving principles that would enhance the impact of gender mainstreaming in the water services sector, and at evaluating current South African guidelines according to these principles. The study was qualitative in nature, and both theoretical and empirical information was used to derive the above principles. The initial literature survey indicated a need for a systemic approach to gender mainstreaming in the water services sector. Therefore, theoretical information was principally obtained from literature on poverty, sustainable development, complexity theory, feminism and governance. Empirical information was obtained from three sources, namely (1) participant observation of the meetings of the Strategic Advisory Group on Gender of the Water Services Sector Leadership Group (WSSLG), (2) individual interviews with a range of stakeholders, and (3) focus group interviews with community members involved in six water services projects – three each in the Eastern Cape and Mpumalanga Provinces. The study resulted in a proposed framework of fourteen focus areas for gender mainstreaming in the water services sector. These focus areas, along with illustrative questions, are the following: (1) Policy premises and formulation (Is the policy premised on equity and poverty alleviation?) (2) Approach to gender mainstreaming (How is the 50/50 campaign being implemented?) (3) The role of the gender officials (Is the gender focal point part of the strategic management team?) (4) Co-operative governance (Are IDP officials and women’s organizations involved?) (5) Public participation (Is the public participation process adequately resourced?) (6) Advocacy and awareness raising (Do family gender relations feature in awareness raising initiatives?) (7) Access to basic services (Are women specifically targeted in service provision?) (8) HIV/AIDS and gender-based violence (What measures are in place to decrease the risk of disease?) (9) Economic empowerment (Are the employment opportunities created sustainable?) (10) Leadership by women (How is the leadership capacity of women being developed?) (11) Capacity development of women (Is the training aimed at portable skills?) (12) Project/programme management (What monitoring and evaluation processes are being used?) (13) Environmental sustainability (What measures are in place to conserve water and reduce pollution?) (14) Engaging with traditional culture (How are restrictive cultural traditions addressed?) When the above framework was applied to the WSSLG Gender Mainstreaming Strategy and Action Plan (DWAF, 2005), the WSSLG strategy was in certain respects found to be non-responsive to the learning garnered in this study. Particularly, the WSSLG strategy neither adopts a poverty alleviation approach, nor addresses environmental sustainability and traditional culture. It also does not facilitate co-operative governance and programme management. Finally, gender inequality in the water services sector impedes both poverty alleviation and sustainable development. Systemic solutions are required, and these study results might be germane to these.

What are the challenges facing municipalities in financing their water services infrastructure? : a case study of water services authorities in the North West Province

Chuene, Tshepo Benny 12 1900 (has links)
Thesis (MDF)--Stellenbosch University, 2012. / The World Bank (1994) concluded that there is a close relationship between infrastructure and economic growth. This also reflects on the water sector because, despite water sector importance, water services infrastructure is probably one of the most difficult to finance, while its deficiency or absence instils a particular burden on society. According to Baietti and Raymond (2005), more than 1.1 billion people worldwide do not have access to safe drinking water, and approximately 2.4 billion are without adequate sanitation. Yet these estimates underestimate the gravity of the situation in relation to access gap and quality of services provided. Most consumers face situations where water services are intermittent and when available the water is not safe for consumption, while sanitation facilities are overloaded, unused or in despair. This research was conducted in the North West Province with municipalities that have the status of water services authorities. This included a combination of district and local municipalities. The North West Province has 11 water service authorities of which nine are local municipalities and two are district municipalities. The competing demands and needs for governments to provide infrastructure for other sectors such as roads and energy further aggravate the stance of finance unavailability for the water sector. The purpose of the study was to highlight the challenges that municipalities face in financing water services infrastructure. The result of the study will provide knowledge and innovative ideas that will allow South Africa‘s municipalities to address challenges of service delivery. At municipal level water services are provided through a variety of approaches, although most involve centralised systems with large supply, distribution and treatment facilities. The social benefits that water services provide are well known, particularly those that relate to public health including reduced morbidity and mortality from waterborne diseases. The challenge is that funding to meet these development objectives is either scarce or entirely unavailable. The Water Services Act 108 of (DWAF, 1997) requires water services authorities and water service providers to put significant efforts into cost recovery for sustainable provision of water services. This aspect has significant challenges which results from widespread poverty and a culture of non-payment from communities inherent as a remnant of protest against apartheid. The scope of the water sector is complex, owing to its diversity, interactions and synergies with other industrial, commercial and financial sectors, and its international nature. Under the current South African constitutional and legislative framework, municipalities will remain to be a major player in the development, financing and delivering of water services infrastructure for sustainable growth and development. Water Services Authorities (WSAs) have responsibilities including protection and management of water resources, provision of adequate and sustainable water services, operation and maintenance of water services infrastructure, monitoring and management of municipal water quality to regulatory requirements and reporting to the Department of Water Affairs (DWA) with regards to the aforementioned. Water service delivery failures at the municipal level are a widespread and fundamental problem in South Africa. At the same time, under the current decentralisation policies, the responsibility for delivering such services is increasingly being delegated to lower levels of government/municipalities that are often ill equipped for the challenge in terms of financial and human resources capacity. Cardone and Fonseca (2006) indicated public administration and financial management capacity at central and sub-sovereign levels of government as limited, and affecting the timely transfer of funding as well as the capacity of municipalities to absorb those funds. Various strategies are needed to enable municipalities to secure and finance their water services infrastructure. These include understanding what bankers are looking for, understanding where donors are going, greater involvement of the private sector, matching service levels to affordability, improving revenues and influencing the regulatory regime.
