Efficiency evaluation of South African water service provision

Brettenny, Warren James January 2017 (has links)
In recent years South Africa has experienced numerous service delivery protests. These protests are a result of the lack of delivery of basic services such as water and sanitation (amongst others). To address this, local governments have taken part in benchmarking initiatives (National Benchmarking Initiative, Municipal Benchmarking Initiative) and regulation programmes (BlueDrop,GreenDrop) in an effort to improve the quality of potable water and sanitation services. The latter of these focuses on the quality of the water services delivered and neither focus on the efficiency with which this delivery is achieved. This study uses both nonparametric (data envelopment analysis) aswell as parametric (stochastic frontier) methods to assess the efficiency of water service provision in South Africa over a six year period from 2005 to 2010. Subsequently, the method which is most suited for use in the South African context is proposed. In addition, this study demonstrates how these methods can be used to determine the effectiveness of benchmarking initiatives, namely the National Benchmarking Initiative, in improving the efficiency of water service provision. Furthermore, additional insight into the selection ofm in them out of n bootstrap procedure for efficiency evaluations is established through a simulation study. The inclusion of efficiency evaluations into South African benchmarking initiatives provides new and important insight into the standard of water service delivery. As such, the techniques used in this study illustrate how efficiency analysis can enhance benchmarking initiatives in South Africa.

Water conservation and water demand management pilot project: the case of Newcastle Municipality

Dube, Sandile Bonga January 2017 (has links)
A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science in Engineering, 2016 / The Newcastle Local Municipality (NLM) has been experiencing water supply interruptions since 2010 due to high demand. Between June 2011 to December 2011, water losses ranged from 49% to 62% (about 23 to 30 megalitres per day) in Madadeni and Osizweni townships (Newcastle East). The suburban areas (i.e. Newcastle West) also experienced water interruptions due to collapsing and/or aging infrastructure. About a thousand households in Madadeni were involved in this study to find the cause of the high water losses. Awareness campaigns, repairing household leaks, installation of intelligent meters and the increase of free basic water in indigent households from 6kℓ to 12kℓ per month reduced water losses from about 246 kℓ to 177kℓ per month. If similar Water Conservation (WC) and Water Demand Management (WDM) could be rolled out to the 35 000 households in the NLM and similar results to those in Madadeni are attained, conservative water saving of about 21Mℓ per day could be achieved. This would reduce the demand on the Ngagane Water Treatment Works (WTW) by 20%. / CK2018

An evaluation of the relationship between water infrastructure financing and water provision in South Africa

Bapela, Lerato Caroline January 2017 (has links)
Thesis (Ph. D. (Administration Development Planning and Management)) -- University of LImpopo, 2017 / Whilst previous research has largely blamed inadequate finance as the cause of insufficient water provision and concomitant development implications such as poverty and food production; this thesis, took a slightly different turn and engaged on a critical deconstruction of the relationship between water infrastructure financing and water provision in South Africa. Archival data on South Africa between 1994 and 2014 were collected on water provision, water-asset finance, governance effectiveness, corruption, violence, accountancy and voice. Data were analysed using the OLS regression fixed effect. Findings from the analysis showed that against popular belief, there was lack of significant relationship between water asset finance and water provision. However, nonfinancial variables namely corruption, social violence, accountability and voice of citizens in development decisions showed a significant relationship with water provision. In addition, the analysis showed that water provision is significantly related to cereal production and incidence of poverty. Therefore, the thesis emphasized that rural development could be enhanced through an improved effort on water provision, which would increase cereal production and reduce the incidence of poverty. It stressed however, that provision of water asset finance without attention and control of nonfinancial variables might have the tendency to derail water provision initiatives in South Africa. The thesis made an original contribution by proposing a conceptual framework for employing and researching the catalyst for water provision in South Africa. It also developed three novel research models for future research. Key words: Infrastructure financing, water infrastructure, water provision, water and development, governance, accountability, poverty reduction

The effectiveness of municipal water service delivery in Hluvukani Community in Bushbuckridge, Mpumalanga

Mogakane, Moses Mbothi January 2018 (has links)
Thesis ( M.Dev.) -- University of Limpopo, 2018 / This study reflects on the effectiveness of municipal water service delivery in Hluvukani community in Bushbuckridge, Mpumalanga. Since the study wanted to have an in-depth understanding of the strategies/methods that the municipality use to deliver water services effectively in Hluvukani, both the qualitative and quantitative research approaches were used. It is within these methodologies that a case study was adopted to seek to deepen the strategies used by government and municipal officials to address the challenges of water experienced by villagers in Hluvukani. Three methods of data collection were used, namely: interviewing, non- participant observation and documents. Hluvukani village was selected as a site for the study by means of purposive sampling. The participants interviewed included the municipal manager, the municipal officials, Hluvukani villagers and officials from the Department of Water Affairs. The documents consulted included the municipal IDP and the 2015/2016 Municipal Budget. This study found that villagers have difficulties in accessing water at Hluvukani and the water service delivery was not effective even though the municipal manager claimed otherwise. This was manifested by the strategies that were used to delivery water such as using delivery trucks to supply water to Hluvukani villages every two weeks. This, the researcher found ineffective as people had to live without water delivery for a period up to four weeks.

Water supply services in Greater Tzaneen Municipality : A case study of Lenyenye Township

Letsoalo, Masilo Simon January 2012 (has links)
Thesis (M.Dev.) --University of Limpopo, 2012 / The aim of the envisaged study is to investigate the water supply services in Lenyenye Township, in Greater Tzaneen Municipality and to derive suggestions and recommendations for improvement based on the objectives decomposed into the following: To review the extent and the magnitude of Water Supply problems and to identify, analyze the underlying causes of the water supply problems because the basic infrastructure provision of water supply is very poor and dismal across the area. Water serves as a basic need to which everybody has the right to access, be it for consumption or irrigation this service is, unfortunately, disrupted by many factors. The findings in the study for poor water supply emanate from many common causal factors such as management skills, technical challenges and illegal connections. Only two methods were employed to collect data in the study. Data collection was done by using the questionnaire and the interview methods and the interview involved direct personal contact with the participants who answered questions. A survey questionnaire was used to obtain data pertaining to water supply services from the representatives of water supply institutions. Recommendations in the study are based on the findings such as prioritization of effective water supply for Lenyenye township, community consultation and participation, addressing capacity constrains in the Municipality such as human resources, water service infrastructure, and skills development.

Thirsty downstream : the provision of clean water in Jakarta, Indonesia

Argo, Teti Armiati 05 1900 (has links)
The challenge of water provision in third world cities is to maintain the supply in the context of inadequate and inefficient piped water infrastructure and diminishing raw resources. In order to examine the role of governance in this, I utilize a range of theoretical positions: the welfare orientation, rational choice paradigm, common goods theory and regime theory, and present them as ways to explore the subjective dimension of water provision. Using the city of Jakarta, Indonesia as a case study, this dissertation explores the issues using different perspectives on a single principal focus, the roles of the government and its relations to non-governmental actors. This research used data from secondary materials such as management reports, policy and academic reports, and scientific studies. The major source of primary data were interviews conducted with about 40 key actors. Qualitative analysis used a system of information coding and triangulation. The conclusion reached is that the approach to managing clean water provision needs to be redefined in relation to the water management regimes found in situated research. In Jakarta, one may define three regimes: piped water, surface and shallow groundwater, and deep groundwater. Accessing water from greater urban watershed, treatment plants and a "manufacturing process" results in the delivery of a product. Such a system reduces the possibility of the tragedy of the commons, that is, the over-extraction of groundwater by individuals. But a more inclusive and enforced regulatory system must be established for groundwater, as it remains a needed source of supply. Local and low-technology solutions, international agency assistance, the policies of privatization and decentralization, and better land use planning, all hold out the promise of movement towards a solution. But, as the case study demonstrates, success has so far been mixed. Many options do not address water scarcity at the city level and problems of inequitable service. It is only the prospect government reform towards a better allocation of roles, new management ideas and greater co-operation within and among the water regimes that will lead to better provision of clean water.

The problems of devolving water management functions to municipalities : the case of Tshwane metropolitan municipality / Amon Benjamin Ntoane

Ntoane, Amon Benjamin January 2002 (has links)
This was a study of the devolution of water and sanitation management functions from the Department of Water Affairs and Forestry and Rand Water Board to Tshwane Metropolitan Municipality. This affects the functions and the infrastructure that goes with it. This exercise is the fulfilment of the provisions of Water Services Act that empowers municipalities to become Water Services Authorities and where capacity exists to also become Water Services Providers. It was found that though constitutionally, water and sanitation functions resort under municipalities, in the area of study, the Tshwane municipality did not directly deliver these functions. This happened due to the fact that Tshwane did not have human capacity to deal with the functions, they provided the funding as a subsidy to Rand Water Board who in turn provided financial support to Odi Retail Water that is currently responsible for water and sanitation management as a subsidiary to Rand Water Board. The following are recommendations derived from the findings: That the political activities be raised in the areas to encourage people to pay for their services and take responsibility for meter reading on their own like it is happening in Denmark. In Denmark each household reads meters for both water and electricity personally and submits the readings to the municipality for billing. As a result the municipality did not employ special meter readers and by so doing they safe on salaries. That greater resource allocation is made to cover the shortfalls that were experienced due to lack of management capacity and other resources that would enable Tshwane municipality to run the functions on their own. That capacity building and support for professionals be streamlined on the current Odi Retail Water staff for future absorption by municipality. 4. That promotion of community-based development be continued to encourage community ownership on water management functions. This could be done through the formation of community water associations. While community-based approaches are now accepted as the norm, the necessary: capacity to support them in most cases does not generally exist at the higher levels (national, district and local) and Tshwane needs to look at this. Communities currently remain uninterested in taking part in wider water management for a number of reasons, including lack of ownership or control over decisions; lack of real power to make allocation and use decisions; high transaction costs of involvement; and poorly developed frameworks by which the views of large communities can be represented at stakeholder fora. Therefore, Tshwane must make sure that community's interest is supported in all respect. If the municipality cannot handle these functions on its own, then privatisation should be considered for efficient and effective water and sanitation management and provision. / Thesis (MBA) North-West University, Mafikeng Campus, 2002

A community-based approach for the operation and maintenance of shared basic water and sanitation services in informal settlements within the municipal jurisdiction of the City of Cape Town

Illing, Cindy January 2009 (has links)
Thesis (MTech (Public Management))--Cape Peninsula University of Technology, 2009 / Access to basic water and sanitation services in South Africa is considered a basic human right, and constitutionally, local government is responsible for the provision thereof. However, in the informal settlements in towns and cities, residents continue to be exposed to environmental health risks that result from poor and inadequate basic sanitation provision. Municipalities are under pressure to address the sanitation backlog according to the national target that is based on the Millennium Development Goals (MDG). The provision of infrastructure alone does not account for the provision of an improved, safer and more hygienic environment for its users. A badly managed sanitation facility is an environmental health risk, and it encourages inappropriate and unsafe sanitation practice. Municipalities cannot claim to meet the sanitation backlog targets unless appropriate and effective management systems are in place to operate and maintain the basic sanitation facilities provided. Through the Integrated Development Plan (IDP) process, local government is encouraged to develop partnerships to promote economic development and job creation, particularly in areas of extreme poverty and high unemployment through the delivery of services. Public participation, social learning, empowerment and sustainability are the key components of the people-centred development approach that currently guides the delivery of municipal services South Africa (Davids,I. 2005). The White Paper on Local Government advocates municipalities to work with communities to find sustainable ways to meet their needs through an approach that is driven by formulating linkages between development, service delivery and local citizen participation (Mogale, T. 2005:219). It is also argued that the only way to effectively link poverty reduction strategies and improved service delivery is through the formation of partnerships that are based on meaningful participation (Mogale, T. 2003). Public participation also allows for an opportunity for increased community buy-in and support that is essential for the sustainable delivery of services to informal settlements so as to reduce incidents of misuse and vandalism. Communication and collaboration across municipal departments is also required, as sanitation service delivery in its broad definition, falls across the Water Services, Health and Solid Waste Departments. Hence the need for an integrated and inclusive approach to planning is required. Using a participatory action research (PAR) process, this study proposes to investigate whether there are local community-based opportunities for the procurement of some of the operation and maintenance tasks for the recently refurbished public ablution blocks in an informal settlement within the City of Cape Town. Public ablution blocks are one of the sanitation technology options available for the provision of shared basic sanitation services provided to informal settlements within the City of Cape Town. The research is divided into three stages. The first two stages serve as the building blocks for the third stage of the research. The objectives are to obtain an improved understanding of the “local knowledge” at community level, to obtain an understanding of the operation and maintenance activities in informal settlements currently being undertaken by City of Cape Town, and to initiate contacts and develop relationships with key stakeholders for their participation in the focus group discussions in the third stage. The third stage of the research proposes to adopt a participatory approach involving key stakeholders to identify the opportunities and make recommendations to the City of Cape Town to consider for the development of an operational plan for the operation and maintenance of the Khayelitsha Ablution Blocks.
