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.

Thesis (MBA)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: South Africa’s efforts to ensure safe drinking-water provision to all have resulted in an admirable reduction in the backlog in drinking-water provision since 1994. However, in the non-metro areas of South Africa poor drinking-water quality is common and, combined with inadequate sanitation, results in a significant and deleterious primary health impact. Given the South African government’s commitment to co-operative government and good governance, and a willingness to both mobilize government funds and to involve the private sector in addressing poor water services delivery by local government, it can be expected that a significant opportunity exists for a “service/product” combination that assists local, provincial and national government in both, (i), the progressive realization of suitable drinking-water quality via a consultative audit, and (ii), an environmental governance function to ensure that acute and chronic issues are timeously identified and resolved. Drinking-Water Quality Management (DWQM) procedures developed and operated by the government research organization, CSIR, have been shown to be effective in achieving (i) and (ii) above. However, CSIR is not the appropriate business environment from which to roll out a commercialized service. This study assesses the prospects of a start-up Small, Medium and Micro Enterprise (SMME) to access and develop the DWQM market in South Africa. A thorough review of the role of governance in the delivery of water services in South Africa is provided, and it is confirmed that DWQM procedures can be expected to contribute towards improvement in drinking-water quality in non-metro South Africa and satisfy government’s requirement of demonstrated good governance (co-operative and regulatory governance) and co-operative government. A situational analysis of the internal (CSIR) and external business environment confirms that a win-win opportunity exists for entrepreneurs from within CSIR to “spin-out” the DWQM services, and thereby fulfill CSIR’s mandate of supporting SMME’s and Black Economic Empowerment (BEE). A summary of considerations for a start-up SMME in South Africa emphasizes the importance of some key factors. A key factor for a SMME selling services to government is the satisfaction of BEE requirements. Additional key factors include the business marketing factors of customer relationship management, delivering value and ongoing evolvement of marketing strategy. A case study involving Stellenbosch Municipality is used to demonstrate the customer centric nature of DWQM, and the positive Value Impact delivered to the client. The above are used to critically consider a Business Action Plan (which has a focus on the first year of operation) and to identify amendments required for the future and separate preparation of a full Business Plan. The short term focused Business Action Plan (BAP) confirms that market forces and opportunities combine with the skills and the background of the start-up team to provide a positive prospect for the startup SMME. Conversion of the BAP to a fully fledged Business Plan will require the development of a full business strategy, and supportive marketing strategy, as the short term focus strategies are inadequate. Importantly, adjustments to the black equity holding should be brought in line with the requirements of the Broad-Based BEE Act. / AFRIKAANSE OPSOMMING: Suid-Afrika se deurlopende pogings om veilige drinkwater te verskaf het gesorg vir ‘n benydenswaardige vermindering in die agterstand in verskaffing van drinkwater sedert 1994. In die nie-metropolitaanse areas van Suid-Afrika is swak drinkwater gehalte egter steeds algemeen en is verantwoordelik, saam met ontoereikende sanitêre infrastruktuur, vir beduidende en dodelike primêre gesondheidsrisikos. Die Suid-Afrikaanse regering is toegewyd tot samewerking met die private sektor en die toepassing van goeie besigheidsbeginsels. Dit is ook gewillig om regeringsfondse beskikbaar te stel indien die betrokkenheid van die privaat sektor kan help om swak waterdienste lewering deur die regering aan te spreek. Daar kan dus verwag word dat ‘n daadwerklike geleentheid bestaan om ‘n “diens/produk” kombinasie daar te stel wat plaaslike, provinsiale en nasionale regering sal bystaan in beide die: (i), progressiewe verwesenliking van geskikte gehalte drinkwater deur middel van ‘n konsultatiewe oudit, en (ii), ‘n omgewings oorsig funksie om te verseker dat akute en kroniese probleme tydig geidentifiseer en opgelos word. Drinkwater Gehalte Bestuur (DWGB) prosedures ontwikkel en toegepas deur die regeringsnavorsingseenheid, die WNNR, is bewys as effektief in die bereiking van (i) en (ii) soos hierbo gemeld. Die WNNR is egter nie ‘n geskikte besigheids-omgewing vir die wyer kommersiële toepassing en verskaffing van sodanige dienste nie. Hierdie studie evalueer die vooruitsigte van Klein, Medium en Mikro Ondernemings (SMME) om die DWGB mark in Suid-Afrika te betree en te ontwikkel. ‘n Deeglike oorsig van die rol van etiese bestuur in die verskaffing van waterdienste in Suid-Afrika word gedoen. Daar word bevestig dat DWGB prosedures na verwagting sal bydra tot die verbetering van drinkwater gehalte in die nie-metropolitaanse Suid-Afrika, maar ook sal voldoen aan die regering se vereistes van daadwerklike en sigbare etiese bestuur (samewerkings en regulatoriese etiese bestuur) en samewerking van die regering en derde partye. ‘n Omgewingsondersoek van die interne (WNNR) en eksterne sake omgewing bevestig dat ‘n wen-wen geleentheid bestaan vir entrepreneurs binne die WNNR om DWGB dienste af te stig, en sodoende ook vir die WNNR om sy mandaat te vervul, by name die ondersteuning van SMME’s en Swart Ekonomiese Bemagtiging (SEB). ‘n Opsomming van die saaklike kwessies vir die stigting van ‘n SMME in Suid-Afrika lei tot die identifisering van ‘n aantal sleutel suksesfaktore se belangrikheid. ‘n Sleutel suksesfaktor vir ‘n SMME, wat dienste aan die regering verkoop, is die voldoening aan SEB vereistes. Verdere sleutel suksesfaktore sluit in die sake bemarkingsfaktor van kliënte verhoudingsbestuur, die lewering van waarde en die volgehoue evolusie van bemarkingstrategie. ‘n Gevallestudie waarin Stellenbosch Munisipaliteit betrokke was word gebruik om die kliënt-gesentreerde toepassing van DWGB te demonstreer, en die positiewe waarde wat aan die kliënt gelewer is, word uitgelig. Laastens word die bogenoemde gebruik om ‘n kritiese evaluering te doen van ‘n Besigheids Aksie Plan (met ‘n fokus op die eerste jaar se bedrywighede). Veranderinge wat vereis sou word vir die voorbereiding van ‘n toekomstige en afsonderlike volledige Besigheids Plan word geidentifiseer. Die korttermyn gefokusde Besigheids Aksie Plan (BAP) bevestig dat marktendense en geleenthede tesame met die vaardighede en agtergrond van die Kleinsake-span ‘n positiewe verwagting skep vir die voornemende kleinsake-bedryf. Die omskakeling van die BAP na ‘n volledige Besigheids Plan vereis ‘n volle Sakestrategie en ‘n ondersteunende Bemarkingsplan, aangesien die korttermyn gefokusde strategieë ontoereikend is. Verdere aanpassings tot die swart aandeelhouding moet gedoen word om te voldoen aan die vereistes van die breëbasis SEB-wetgewing.

A project report submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science in Engineerrng, / As has happened throughout the world. environmental and water quality problems related to developing urban and industrial areas and associated accumulation of waste in built-up areas were the main factors in contributing to sanitary awareness in South Africa. The dwindling water resources and persistent deterioration of water quality, more severely in urban areas, necessitates the review the current practice of storm water management in South Africa. Reliable stormwater drainage models evaluating both the water quantity and quality could be essential in confronting the prevailing pollution problems. The objective of this project was conceived to be the development of a system for the simulation of water quality in urban watercourses, A personal computer compatible model for joint transportation of hydrograph and pollutographs in open channels was developed. The model comprises an operational data handling facility, a user friendly and interactive interface. The study revealed that: Urban and Industrial development results in complication of the urban water system. • Single objectivity approaches in management of urban watercourses are outdated . .. The proposed model is capable of simultaneously routing flood and pollutant condiment waves in open channels. Understanding of aspects of the water quality in urban watercourse can be greatly enhanced by the proposed model. The following recommendations were henceforth made: • Detailed study of the nature. quantity and sources of pollutants in the urban water system. .. Sophisticated (dynamic wave. supercritical flow, complicated ..................... hydrodynamic model snould be considered, • Biological and, chemical process in the urban watercourse be incorporated. • Linking of the water quality model to the storm water drainage model, / Andrew Chakane 2018

Evaluating trends of historical rainfall on a weekly and seasonal basis is needed for optimizing the design and implementation of lawn water conservation strategies like outdoor water restrictions. While “day of the week” water restrictions are a typical strategy to limit the frequency and duration of urban lawn water use, they may not necessarily result in more conservative behaviors from end-users. Because weekly rainfall and local climate variables are seldom taken into account in water restriction strategies, they are not connected to actual lawn water demand. However, since lawn water demand is directly related to weekly rainfall totals, not to a particular number of watering days per week, water restriction schedules have the potential to unintentionally promote overwatering. This study investigated the weekly patterns of average seasonal rainfall and evapotranspiration in South Florida to determine the typical variability of weekly net irrigation needs and found that typical wet season weekly rainfall often provides a significant amount of water to meet the demand of residential lawns and landscapes. This finding underscores opportunity to reduce supplemental overwatering in residential landscapes if watering guidelines were modified to recognize seasonal average weekly rainfall in this region This study also tested a rainfall-based water conservation strategy to determine if providing residents with information about how local rainfall could promote more effective lawn watering behavior than just water restrictions alone. Experimental households reduced lawn water use by up to 61% compared to the control group by the end of the study. These results demonstrate that the neighborhood “rain-watered lawn” signs helped experimental study group households become more aware of rainfall as the primary input of water to their lawns. This study also investigated the role that lawn irrigation from self-supplied sources plays in the urban lawn water demand and investigates how the lawn water use and lawn watering behaviors of households that source from self-supply differ from those who source from the public supply. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection
