Thesis (DTech (Design))--Cape Peninsula University of Technology, 2017. / The introduction of water service programmes has significantly improved the delivery of Water and Sanitation Services to marginalised communities in Kenya. Since the implementation of the Kenya Water Act of 2002, enacted policies have resulted in communal ablution blocks and water kiosks in some of the more densely populated settlements. In the development of service provision programmes to improve access to water and sanitation, the social and cultural implications have yet to be addressed. To better understand the partnerships between the marginalised community and the political agencies that ensure improved allocation of resources, community participation should be addressed in the emerging water governance. The right to water is a key clause in the new constitution of Kenya and although this is a laudable recognition of citizens’ rights to basic services, this constitutional clause is yet to be fully implemented. The exclusion of social practices followed by marginalised communities results in limits in the promotion and implemention water and sanitation projects. The resulting lack of water and sanitation services decreases the internal capacities of community members and inhibits development. A natural and finite resource such as water, often taken for granted by most, is the foundation to improved places in a community. These places reflect social relations within the given society and provide a platform for interaction. When this engagement occurs, meaning in both physical and social boundaries between different communities that emerge, can help assert agency to marginalised groups. While a programme is used to define a space by regulating through building codes and standards, a community’s role is validated by the inclusiveness of the design process. Therefore the resultant project allows for a sense of agency to be built, while boosting interaction through learning programmes, to improve civic duties in the society. These aspects are crucial for development and can be achieved using allocation of basic services like water and sanitation. Grounded Theory is used to analyse the interviews from the respondents and it concerns itself with the meanings attributed to steps within processes. This approach is applicable when meanings attributed to macro-level explanations and micro-level activities need to be uncovered. The interviews conducted for this study are analysed line-by-line coding and memo writing. The data is used as a narrative of distinct processes in both marginalised communities and political agencies. Using the model of an agent the study illustrates the process of agency that highlights the role of marginalised communities in participatory approches toward equitable access to water and sanitaion services. The cases approached in this study further articulate the processes used by political agencies to engage in community participatory approaches. Though these participatory approaches were seen to be more inclusive than previous service delivery approaches, gaps emerged in the study that are addressed in the relationship matrix. This model distinguishes the differences in the production of space through Water and Sanitation Service programs, and the creation of place in implemented projects. By aligning these two aspects of the production of space when applied to marginalised settings helps in understanding the context prior to the implementation of WSS development programmes. This recognition of the role that marginalised communities play in socioeconomic development can improve programmes and projects aimed at providing water and sanitation services. This access is important to marginalised groups which are disadvantaged, because of a difference in their practices. By understanding the social practices around the use, management and safeguarding of water and sanitation projects, community members can begin to attach cultural value to their water resources. This has implications for the sustainability of the projects and their replicability. Therefore social practices, and by extension culture, influence the concept and design of programmes to enable access to water and sanitation resources, especially to marginalised groups in society.

A conceptual end use model for residential water demand and return flow is presented in this thesis. The model requires a unique description of a single residential stand in terms of all its end-uses. The end-uses include toilet flushing, bathing and showering, garden watering, leaks, et cetera. Various parameters describe each of the end-uses. The model predicts five components relating to water demand and wastewater flow at a residence: indoor water demand, outdoor water demand, hot water demand, wastewater flow volume and concentration of solutes in the wastewater. Twelve monthly results are calculated, for each of the five components, to provide a typical seasonal pattern as well as an annual value. The large number of input parameters in an end-use model allows for powerful and detailed analysis. The parameters required to populate the model are discussed and guideline values are presented. The end-use model is used to conduct a sensitivity analysis of each independent parameter for each of the five individual model components. The elasticity and sensitivity is determined at a base point with respect to each parameter for all five results. A research significance index is also devised to integrate the elasticity and availability of data for each parameter. The result is a prioritised list of the most critical parameters for each of the five components, which are the ones that should receive the focus for future study and data recording. The parameters are combined to obtain a list of the overall most important parameters in the model for all components combined, and based on a combination of the elasticity-based rank and the sensitivity based rank. The five most important parameters are the household size, toilet flush frequency, toilet flush volume, the washing machine event frequency and the volume of leaks on a stand. The practical application of the model is illustrated. The researchers first apply the model to mimic a few commonly accepted characteristics of water demand. The effectiveness of some specific water demand management measures are evaluated by adjusting selected model parameters. The measures include xeriscaping, the installation of dual-flush toilets, low-flow showerheads, pool ownership and pool cover use. The model also enables practitioners to obtain an insight into the water use habits of homeowners. The model forms the basis for further research work in the field. Its relatively simple structure and realistic data requirement encourages its integration into existing commercially available software suites for water and sewer system analysis and -management in the civil engineering industry in South Africa, as well as abroad. / Prof. J.

M.Ing. / An investigation was conducted on on-site leakage in selected suburbs of Johannesburg to determine the average leakage flow rate of water lost per property, as well as the distribution patterns of leakage flow rates for two categories of properties: Residential (single domestic houses on stands) and Other (non-domestic and large domestic users). The incentive of this research project, funded by the Water Research Commission (WRC) of South Africa, was to provide figures and to gain insight into the magnitude of water lost at the consumer level, also defined as "on-site leakage". Little was published on on-site losses compared to water losses in municipal distribution systems. The key information for this study was collected through physical inspection of a group of randomly selected properties and by means of measurements taken from municipal water meters used for billing purpose. The project was assisted by Johannesburg Water (Pty) Ltd who provided a list of 233 properties having water meters of less than five years old. These properties were chosen at random and included properties whose meters were replaced due to meter failure or customer complaints. The results of the research show that overall 64 % of investigated properties had measurable on-site leakage at an average rate of 22.9 I/h per property, equivalent to a monthly volume loss of 16.5 kl per property. The median rate was 5.7 I/h per property, translated into a volume loss of 4.1 kl/month per property. An analysis of the data revealed that the general extreme value distribution and its derivatives (Frechet, Wakeby, Exponential and Gamma) provide good descriptions of the distribution of on-site leakage rates. The apparent losses resulting from metering errors were also estimated. The results of this study should be of interest to water engineers and to decision-makers involved in water demand management. It could form a basis for further investigation in the analysis of on-site leakage on a large scale in South Africa by systematically monitoring all segregated categories of users throughout different cities and towns in South Africa.

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. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Techniques for performance optimization and energy reduction were reviewed for application to water supply plants. Simple techniques were developed which permit intelligent management decisions for plant operation growth. The techniques were applied to the Wewahootee Water Supply Plant, Cocoa, Florida. Optimum performance for the existing plant was determined together with a growth plan for reducing energy consumption and increasing the maximum flow capacity to meet demand through the year 2000. The following recommendations were made: 1. Plant operators should incorporate the optimized pump operation schedule presented herein. 2. Four existing pumps should be modified for dual speed operation, and a large capacity dual speed pump should be added. 3. One 10,400 foot section should be added to the 42-inch pipe by 1985 and a second section by 1990. 4. An economic analysis should be performed to determine if it is advantageous to accelerate installation of the 42-inch pipe. 5. The use of stored water should be considered to smooth the flow demands placed on the pumps.

A research report submitted to the School of Civil and Environmental Engineering, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science in Engineering, Johannesburg, 2017 / Human beings depend on water not only for life itself but also for their economic wellbeing. Water resources play a cardinal role in the creation of everything that human beings produce. Post-apartheid South Africa is in the throes of incredible challenges. One of the more important challenges is access for all citizens to basic services. South Africa is doing this against a backdrop of strongly differential servicing that is its apartheid legacy, which has prompted many commentators to label South Africa a country of two worlds, more specifically, a developed world component and an impoverished developing world component. The challenge with respect to water is to ensure universal access in the context of the added hurdle of South Africa being a water-scarce country. The local municipalities of the Eastern Cape have been facing a number of challenges in the provision of clean, portable water to their communities. This has resulted in inadequate provision of water, meaning that not all communities have access to clean water 24 hours a day The overall objective for this study is to contribute to the body of knowledge available to the water sector about the management of sustainable water supply systems in municipalities, and determine the factors that have undermined the sustainability of water provision at a local government municipal level in the Eastern Cape Province of South Africa. In this research, the effectiveness of local governments, which act as water services authorities (WSA) and providers of water to the rural communities, is examined. To this end, a comprehensive literature review was conducted and data gathered to discover why there has been a failure in the provision of clean drinking water. The results of the research illustrate that institutional incapacity in rural municipalities and widespread poverty serve to undermine the sustainability of the local government sector and lead to breakdowns in services delivery. Measures are proposed that can be adopted to improve the current approaches of water supply in local municipalities. / CK2018

Water conservation initiatives seldom quantify the volume of water that is at stake in lawn watering. In many communities, including those in South Florida, outdoor water use, which includes lawn irrigation, is not metered separately from indoor water use and is indistinguishable from indoor water usage. A large number of residents use self supply non-potable wells for lawn irrigation that are not regulated by the South Florida Water Management District. The result is that residential lawn water use is difficult to account for and quantify. This thesis project addressed these difficulties by combining semistructured interviews, daily watering observations and irrigation system audits to ascertain how much public supply water and self supply (well) water was being used for residential lawn irrigation. The study also examined lawn watering practices and how factors such as: precipitation, the minimum plant needs of St. Augstinegrass, and how local watering restrictions influenced watering behavior. / by Felicia D.

Water is both a human right and a valuable commodity. Access to water for the rural poor is an international development concern that has been highlighted by the Millennium Development Goals adopted at the Millennium Summit in 2000 in Dublin, Ireland. South Africa's Free Basic Water policy is the government's response to assuring access to water for all - especially those who cannot pay. The policy, however, is required to work within an economic framework that promotes cost recovery and privatisation. The Free Basic Water Policy was officially implemented in July 2001. The policy was rolled out in most urban areas on or near this date. However, in rural areas it has proven much more difficult, and there are many areas that have not yet seen the implementation of Free Basic Water (FBW). This is partly due to varying financial, technical, political and logistical problems at the local and district municipality level. This research investigates the current situation in rural municipalities, looking specifically at FBW policy, institutional arrangements, operation and maintenance costs, cost per capita and affordability in relation to the Equitable Share allocations. Five case studies - compiled through interviews, document analyses, Participatory Rural Appraisal, and workshops provide a broad scale research base from which to analyse the current implementation of FBW in rural municipalities and ascertain whether this policy is affordable at this level. Water Service Authorities (WSA) are at varying levels of implementation, with few having a fully operational policy that is reaching rural areas. A costing exercise revealed that the service delivery price of water varies, but does follow a trend. From this trend a benchmark cost per capita of R5.84/month was determined. This price, although low, is not currently affordable in some municipalities due to insufficient government grants from National Treasury. These grants are fundamental to the sustainability of FBW and the situation must be resolved if FBW is to reach its target market - the poorest of the poor. The mixed success in the implementation of Free Basic Water in rural areas of South Africa should not be taken as indicative of future trends. As the local government transition to newly devolved powers and functions is completed, the capacity at this level to resolve the challenges is more likely. Subject to the continued strength of the South African economy, this policy could be a solution to the historical failure of service delivery to rural areas. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

This project developed a model for effective asset management drawn from successful programs in the United States, Australia, and New Zealand. Asset management practices were examined at the City of Ontario Utilities Department; a medium sized utility, and also at the Rainbow Municipal Water District, a small sized utility. Gaps between the ideal model and the existing practices were investigated.

Thesis (MPA)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: This study gives an analysis of urban water services provision in Zimbabwe in general. The case study of Harare Municipality was used to get an in-depth analysis of urban water provision in an urban set-up and assess the possibility of private sector engagement for water provision. The engagement of the private sector through Public- Private Partnerships (PPPs) in the provision of public services has become a common practice in many countries. The overall benefits noted for the use of these partnerships include increased effectiveness and efficiency of service delivery. The private sector has been favoured for the provision of services, given the financial and expertise benefits that it brings into public service delivery. Water services delivery in many countries in Africa has been dogged by a plethora of problems that include, water losses, poor revenue collection, lack of cost recovery, inadequate financial investment to expand water infrastructure and overall inability to meet demand resulting from urban expansion. Given these challenges, PPPs provide an option for service delivery. These partnerships have been in the form of leases, management and service contracts, as well as concessions for the provision of public services. Private sector participation (PSP) in service delivery in different forms is rooted in various theoretical ideologies that include New Public Management (NPM), Public Value, New Governance and Network Governance. The reduction of the role of government in the provision of public services; the adoption of private sector management style; the use of networks in service provision and participation of the stakeholders are key principles in these theoretical ideologies. These principles have thus been adopted through public sector reforms for service delivery. Case studies from Senegal, Kenya, South Africa and Tanzania are applied in this study, to take note of key lessons on the engagement of the private sector for provision of urban water services, as well as the key determinants of successful partnerships. The institutional and legal framework of reforms undertaken in these countries are analysed as part of the enabling environment for successful partnerships. Data collection for this study was done through key informant interviews, covering water administration issues, water provision challenges and private sector engagement in Harare. The obsolete water infrastructure and inadequate financial levels have affected water provision and coverage in Harare. Unaccounted for water was found to be above 30 percent for the City of Harare, whilst water production levels are much lower than demand. Attempts at engaging the private sector for improving water provision through a concession for the Kunzvi Dam Project have not gone beyond the signing of the contract. What is clear is that there is a lack of a regulatory framework; political willingness, lack of trust, economic uncertainty, lack of financial sustainability and a performance monitoring framework. These are key factors in ensuring a viable public- private arrangement. For private sector involvement to be successful, in the context of this study, the recommendations include the need for a regulatory framework for PPPs in Zimbabwe, establishment of a regulator through policy, political willingness and transparency. / AFRIKAANSE OPSOMMING: Hierdie studie bied ’n algemene analise van stedelike watervoorsieningdienste in Zimbabwe. Die gevallestudie van die Harare-munisipaliteit word gebruik ten einde ’n in-diepte analise van stedelike watervoorsiening in ’n stedelike omgewing te bekom en om die moontlikheid van privaatsektor-betrokkenheid ten opsigte van watervoorsiening te assesseer. Die betrokkenheid van die privaatsektor deur middel van Openbare-Privaatvennootskappe met die oog op die verskaffing van openbare dienste het in vele lande wêreldwyd algemene gebruik geword. Die algehele voordele vir die gebruik van sulke vennootskappe sluit verhoogde doeltreffendheid en deeglikheid van diensverskaffing in. Die privaatsektor geniet voorkeur vir die voorsiening van dienste gegewe die finansiële en kundigheidsvoordele wat dit aan openbare dienslewering toevoeg. Die lewering van waterdienste in vele lande in Afrika word deur ’n oormaat probleme geteister wat waterverliese, onvoldoende betalings, gebrek aan kosteverhaling , onvoldoende geldelike beleggings om waterinfrastruktuur uit te brei, en die algehele onvermoë om aan die aanvraag weens stedelike uitbreiding te voldoen, insluit. In die lig van die vermelde uitdagings bied Openbare-Privaatvennootskappe ’n opsie vir dienslewering. Dié vennootskappe is in die vorm van huurkontrakte, bestuurs- en dienskontrakte, sowel as konsessies vir die verskaffing van openbare dienste, vergestalt. Deelname deur die privaatsektor aan dienslewering in verskillende vorme is gewortel in verskeie teoretiese ideologieë wat Nuwe Openbare Bestuur, Openbare Waarde, Nuwe Leiding en Netwerkleiding insluit. Die vermindering van die regering se rol in die voorsiening van openbare dienste; die aanvaarding van privaatsektor-bestuurstyl; die gebruik van netwerke ten opsigte van diensverskaffing en die deelname van belanghebbendes, is sleutelbeginsels in hierdie teoretiese ideologieë. Hierdie beginsels is dus deur openbare sektorhervormings met die oog op diensverskaffing aanvaar. Gevallestudies uit Senegal, Kenia, Suid-Afrika en Tanzanië is in hierdie studie toegepas met die oog daarop om sleutellesse rakende die betrokkenheid van die privaatsektor ten opsigte van die voorsiening van stedelike waterdienste ter harte te neem, sowel as die sleuteldeterminante van geslaagde vennootskappe. Die institusionele en wetlike raamwerk van hervormings wat in vermelde lande onderneem is, is geanaliseer as deel van die geskikte omgewing vir geslaagde vennootskappe. Data-insameling vir hierdie studie is gedoen deur sleutel ingeligte onderhoude wat wateradministrasie-aangeleenthede, watervoorsiening-uitdagings en privaatsektor-betrokkenheid in Harare dek. Die afgeleefde waterinfrastruktuur en onvoldoende finansiële stelsels het watervoorsiening en dekking in Harare geraak. Daar is bevind dat die onverantwoordbaarheid ten opsigte van water in die stad Harare bo 30 persent was onderwyl waterleweringsvlakke veel laer is as die aanvraag daarvoor. Pogings om die privaatsektor te betrek by die verbetering van watervoorsiening deur middel van ’n konsessie vir die Kunzvi Dam-projek, het nog nie verder gevorder as die kontrakondertekening nie. Wat duidelik is, is dat daar ’n gebrek aan ’n reguleringsraamwerk bestaan, daar is geen politieke wil nie, daar heers algemene gebrek aan vertroue, ekonomiese onsekerheid en ’n gebrek aan finansiële volhoubaarheid, en daar bestaan nie ’n prestasiemoniteringsraamwerk nie. Hierdie is sleutelfaktore ten einde ’n lewensvatbare openbare-private ooreenkoms te verseker. Om privaatsektor betrokkenheid – in die konteks van hierdie studie – geslaagd te maak, sluit die aanbevelings die volgende in: die behoefte aan ’n reguleringsraamwerk vir Openbare-Privaatvennootskappe in Zimbabwe, die totstandkoming van ’n reguleerder deur middel van beleid, ’n politieke wil en deursigtigheid.
