Persepectives on market processes followed in setting South African water services tariffs

Norden, Ryan Henri January 2012 (has links)
South Africa’s private sector and the practice of using market processes are often dismissed by the government as service providing options, because they increase costs and fail the poor population. There is some substance to the government’s position, given that there is a natural monopoly advantage in water service provision. Under these circumstances it could be expected that a single firm would emerge as dominant in the provision of these services to urban customers. Were this firm a private one, and unregulated, it could be expected to practice exploitative pricing, make excess profits, and undersupply waste water management service. A private firm would also not provide services to the poor unless their service was subsidised. However most of these deficiencies can be regulated (as shown in Chapter Four), and also occur under public sector provision (as shown in Chapter Five) Are the private sector failures sufficient reason to abandon the market and private sector as mechanisms to deliver water service in South Africa? This dissertation finds little use is made of market processes and the private sector in water service provision (Chapter One), despite there being legal provision for such involvement (Chapter Two). It also finds that public water service providers are not subject to competition policy and consumer protection provisions, whereas private sector providers would be (Chapter Three). The administration of questionnaires to municipalities and the Department of Water Affairs (DWA) show that the various water service providers often operate under unique circumstances, making it difficult to extrapolate management insights from one municipality to another (Chapter Six). A case study on Nelson Mandela Bay Municipal tariff setting reveals a mismatch between economic principle and policy practice, and suggests that economic principle plays a lesser role in the design of tariff structures than other factors (Chapter Seven). Given the problems that are occurring in public sector water service provision, the dissertation concludes the case for dismissing private sector or public utility models for water service delivery may be weaker than is believed by the South African government.

A Study to Develop Strategies for Proactive Water-Loss Management

Park, Hyun Jung 21 November 2006 (has links)
A Study to Develop Strategies for Proactive Water-Loss Management Hyun Jung Park Directed by Dr. Mary Beth Walker Water conservation is one of the important policy concerns. However, most water conservation practices have focused primarily on reducing use by customers. Since a large amount of water lost in supply systems causes water providers to lose money, resources, and reliability, and the current passive approach cannot deal with water losses effectively, a proactive approach is necessary for water-loss management. The goal of this study is to help policymakers and water utilities develop strategies that proactively solve water losses. To develop strategies for water-loss management, it is essential to identify key factors that determine the level of water losses as well as the factors that encourage the adoption of the innovative control practices. Using three different datasets and statistical methodology, this study analyzed the factors associated with water losses and utilities responses to the problems. Based on case studies, this study explored managers perceptions about the adoption of water-loss management and identified organizational characteristics that may influence managements decisions to adopt such strategies. Operational and Maintenance (O and M) factors had the most significant impacts on water losses. In particular, system size, represented by total production or population served, and infrastructure rehabilitation were crucial factors. The effects of some internal factors on water losses were predicted but those of several internal factors were rather unclear and relatively complicated. This study confirmed that utilities were more likely to be motivated to combat water losses if certain external conditions, such as higher water demand, limited resource availability, and institutional pressure exist. This study found several internal and external factors associated with the adoption of proactive water-loss management; however, internal factors seemed to dominate in the decision-making processes over such adoption. The utilities that have already adopted proactive water-loss management seem to be more amenable to adopt new practices because they have certain characteristics and their managers have more positive perspectives. The findings suggest several policy implications and recommendations for the water industry. Finally, this study discussed limitations of the study, and suggestions for further studies.

The economic geography of urban water infrastructure investment and governance : a comparison of Beijing and London

Yang, Yin January 2015 (has links)
Urban infrastructure is the key physical asset for successful functioning of modern cities. Yet the building and maintaining infrastructure networks require robust institutions, either expressed explicitly in rules and regulations or implicitly in social norms and mutual expectations, which are crucial for governing the complex relationships among all stakeholders including governments, regulators, investors, utilities and consumers that underpin the production of infrastructure services. Although there are more and more studies focusing on infrastructure, the underlying institutions that sustain the 'sink' of long-term accumulation of finance, technology, organisational and geopolitical power for shaping urban landscape have often been neglected. In particular, few studies have investigated the uneven geographical phenomenon of urban infrastructure investment and governance. As such, this thesis compares and explores how and why political, institutional and governance frameworks in Beijing and London influence urban water infrastructure investment and service delivery differently. The findings from the comparative study of the thesis should assist better understanding of 'variegated capitalism', especially state capitalism versus liberal capitalism. Through case study and close dialogue methodology, this thesis compares and investigates the investment models, governance frameworks, pricing systems and infrastructure contracts for urban water infrastructure in Beijing and London from the perspective of economic geography. Based on the theories of institutional and relational economic geography, this thesis organizes the study into four substantive chapters: Chapter Three compares the investment models employed in Beijing and London for water infrastructure investment and the underlying institutions; Chapter Four explores the effects of different governance frameworks on urban water infrastructure investment and service delivery in Beijing and London; Chapter Five investigates the effects of different pricing systems in the two cities for coordinating the intrinsic, market and investment value of urban water infrastructure; Chapter Six analyses different infrastructure contracts for financing large-scale water infrastructure projects in the two cities. The thesis finds that institutions are embedded in time and space for harnessing the flows of capital and producing the configurations of infrastructure provision, thus shaping the heterogeneous landscape of the material, economic, social and geopolitical fabric of contemporary cities. Therefore, in contrast to the statement 'form follows function', this thesis argues that infrastructure functions are inherently geographical in nature. The thesis has made the following contributions: firstly, it has compared the various trajectories of urban water infrastructure investment and governance in different political economic contexts, especially the dialogue between Global North and South, making original contribution in the 'geography of infrastructure'; secondly, the thesis employs cases studies to compare and investigate institutions empirically - issues that have been neglected for much too long in mainstream economic geography, contributing to 'variegated capitalism'; finally, in practical terms this research provides information for governments, regulators, investors, infrastructure providers and other stakeholders on in-depth understanding of urban water infrastructure investment and governance in different institutional and relational contexts.

An analysis of strategy plan on business performance of a water utility : a Midvaal water company case study / Erven Sello Malatji

Malatji, Erven Sello January 2014 (has links)
The purpose of the research was to assess the strategic management process of a water utility in South Africa. The research focused on Midvaal Water Company, a section 21 water utility based in South Africa, North West Province town of Klerksdorp. The objectives of the study were; (a) to assess the organisational level of knowledge when it comes to SMP, (b) to determine different perceptions with regards to SMP between management and employees, (c) to determine the organisational profiles (age, gender, educational qualifications, race and employment type). Literature review was conducted covering the South Africa water framework paying particular attention to different role players and legislative framework governing the sector; the latter included the strategic management process of a water utility as applied in the Midvaal Water Company context. The research approach was quantitative methodology, which involved distribution of questionnaires as part of field work in the water utility. Questionnaires were analysed through statistical approach, and further linked back to the problem statement. The questionnaires were also tested for Validity and reliability which was found to be acceptable. The results indicate that there is a correlation between strategic management process and organisational results. The results also provide interesting relationships between variables that can be explored further. In conclusion successful implementation of strategy requires both leadership and employee commitment. More effort needs to be put in place to ensure that there is an understanding of company values mission and vision. As part of the succession planning the water utilities should consider succession planning as a tool to develop future leaders, by identifying future potential leaders and involving them in the strategy crafting process can help in creating a pool of competent future leaders that will contribute to the well being and sustainability of the water utility. / MBA, North-West University, Potchefstroom Campus, 2015

The influence of customer perceptions of urban utility water services on bill payment behaviour : findings from Uganda

Kayaga, Sam January 2002 (has links)
Intensive research activities in low-income countries during the International Drinking Water Supply and Sanitation Decade (1981-1990) led to the conclusion that cost recovery is a prerequisite for the sustainability of water services provision. The challenges for cost recovery are greater in urban areas of low-income countries where, it is projected, 88% of all the increase in global population will live by 2015. In spite of these challenges, available data show that the bill collection efficiency in selected urban water utilities in Africa in 1996/97 ranged from as low as 50%. This study used empirical data, obtained through a cross-sectional survey in eleven towns in Uganda, to establish the influence of customer perceptions on bill payment behaviour. Using qualitative methods, a questionnaire was developed, pretested, piloted and refined, before it was sent to a probability sample of 690 registered customers of an urban water utility. Regression analysis of the obtained results showed that customer perceptions of technical quality, functional quality, service value and corporate image are individually strongly related to customer satisfaction. Correspondingly, service value and customer satisfaction predict substantial variation in customer loyalty, which in turn is a predictor of bill payment behaviour. Furthermore, gender, level of education, and type of occupation of the head of household, together with tenure status and household income, moderate the satisfaction/loyalty relationship. Findings of this research also highlighted the relative importance to customers of urban water utilities of such software attributes as: (i) how interface staff relate to customers during service encounters; (ii) how easy it is to transact with the utility, and (iii) the image organisational personalities project to the public. These findings have one major implication for supply-driven managers of water utilities: Similar to other services, customer orientation will improve profitability ratios in the urban water sector of low-income countries.

An investigation of a partnership approach for providing water services to informal settlements in Dar-Es-Salaam and Lilongwe

Ndezi, Timothy P. January 2007 (has links)
This thesis investigates whether adoption of partnerships between water utilities and Community Based Organisations (CBOs) in Sub-Saharan Africa can improve water services to informal urban settlements. The study is particularly relevant because over 1 billion of the world's population have no access to clean water supply with many living in urban areas. The lack of adequate resources coupled with insufficiency of conventional approaches has rendered it impossible for urban utilities to deliver sustainable water services to all customers, including the informal settlements. The thesis proposes that partnership between water utilities and CBOs is a viable approach for improving water services to informal settlements. The thesis enhances understanding of the context in which such partnerships could be developed.

Strategic risk management in water utilities : development of a holistic approach linking risks and futures

Linares Luis, Ana Margarida January 2014 (has links)
Risk management plays a key role in water utilities. Although tools are well established at operational and tactical levels of management, existing methods at strategic level lack a holistic treatment and a long-term perspective. In fact, risks are analysed per se, despite being interconnected; and long-term scenarios are commonly used for strategic planning, rather than for risk management, most of the time being related to one single issue (for example: climate change). In order to overcome the limitations identified in the existing methodologies, a novel approach for water utilities to manage risk at strategic level was developed and tested in EPAL - the largest and oldest water utility in Portugal. It consists of (i) setting a baseline risks comparison founded on a systemic model developed ‗bottom-up‘ through the business; (ii) the construction of future scenarios and an observation of how baseline risks may change with time. Major contributions of this research are the linkage between operational and strategic risks, capturing the interdependencies between strategic risks; the ability to look at long term risk, allowing the visualizing of the way strategic risks may change under a possible future scenario; and the novel coupling of risks and futures research. For the water sector, this approach constitutes a useful tool for strategic planning, which may be presented to the Board of Directors in a simple and intuitive way, despite the solid foundations of the underlying analysis. It also builds on in-house expertise, promoting the dissemination and pervasiveness of risk management within the companies and, on the other hand, allowing unveiling of existing knowledge, making it explicit and more useful for the organization.

Measuring water utility efficiency using fuzzy logic

06 November 2012 (has links)
D.Ing. / Measuring the efficiency of water utilities has been a constant challenge to various stakeholders in the water sector. There are several factors that influence the efficiency of utilities. The following study examines the different factors and establishes a model to quantify the efficiency of water utilities using limited number of variables. It utilises Fuzzy Logic to develop the measurement model. The developed method can also be used to configure a new water utility for efficiency. In addition, the research highlights some possible imperfections in the water policies that can result in an inherent inefficiency of a water utility. The developed model can assist in setting ceiling levels for utility's water assets and labour, to ensure efficiency. The model is generic and can be applied to any country or community, and can be used to configure water utilities for the poor. The Model utilised "Matlab Fuzzy Tool Box student version 2009a" software as a tool to develop the Fuzzy Inference Engine for Utility Efficiency. The study is a contribution to the domain of knowledge of water engineering science.

Customer contributions to water sector planning and decision-making in England and Wales

Sayles, Rebecca January 2015 (has links)
Mounting recognition of the socio-political context of the management of water resources has rendered the application of technocratic approaches in isolation insufficient in addressing future management challenges with participatory approaches increasingly promoted in response. Against this background, new regulatory mechanisms in the water sector in England and Wales promise an increased role for the views of customers in water utility planning and decision- making. Yet, existing scholarship on the institutionalisation of participative approaches in water utility planning and decision-making in England and Wales is sparse. This thesis contributes to an improved understanding of factors that hold potential to impact institutionalisation of participative approaches in this context by focusing on three specific aspects of effectiveness; motivational clarity, the influence of participative mechanism design, and the use and influence of water utility customer contributions in water sector planning and decision-making. This has been achieved through the deployment of participatory research in collaboration with the sponsoring organisation (a water utility operating in England and Wales) utilising group discussion and semi-structured interviews with domestic water customers and water utility practitioner respectively. Findings demonstrate that preference elicitation vehicles embedded within participatory mechanisms hold the potential to influence participants expressed preferences thus representing a key design consideration where multi- mechanism approaches are deployed in planning and decision-making contexts. Furthermore, useful design considerations for multi-attribute presentation in participatory mechanisms are presented. Findings also identify a dominance of instrumental and legalistic practitioner motivations for the use of participative approaches in water utility decision-making. Foremost, it identified the significance of the regulator in driving water utility practices for the management and influence of customer contributions in planning and decision- making, and more fundamentally illustrates the significant barrier posed by a legacy of technocratic practices for the institutionalisation of participatory approaches in water utilities.
