Inadequate resources have always been suspected to be the main cause of persistent poverty and underdevelopment in many developing countries. Water is one such resource that is not readily available to many in South Africa. South Africa is a water-scarce country; access to adequate water provisions requires expensive infrastructure which can only be provided by the Government for most of the population. It is not certain whether there is a direct link between access to water and development or poverty alleviation. This study evaluated the impact that state water provision has on development especially in rural communities. The study concluded that there is indeed potential for community development where there is improved access to water. Findings further revealed the nature of several other variables that have significant roles in the relationship between access to government provided water and development. / Development Studies / M.A. (Development Studies)

Thesis (PhD)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: This study describes and analyses the water governance and developmental water services education and training needs of councillors in water services authorities (WSAs) in the Northern Cape Province in order to enable them to fulfil their responsibilities as required by the legislative framework in the new dispensation in South Africa. The new South African Constitution ushered in a new legislative framework, which recognises that developmental water supply, sanitation facilities as basic services are local government matters, and that they are in the functional area of concurrent national and provincial legislative competence. The Water Services Act No. 108 of 1997 and a number of Acts of Parliament thereafter, which are a spine for a local government developmental agenda (LGDA) in South Africa, give effect to this determination. Collectively, these Acts and policies have set the LGDA or modernisation of local government for change and marked a departure from the selection, recruitment and deployment of councillors without minimum engineering and technical skills in water and infrastructure planning and development portfolios. This invariably imposes new leadership responsibilities upon a range of hydropolitical councillors in WSAs, and creates the need for a redefined model of representation on the part of councillors from ―resemblance to public capability, accountability, responsibility and responsiveness‖ (Sartori 1968: 465). With the current calibre and breed of councillors in water portfolios and infrastructure planning and development, it appears that the country is facing a leadership crisis that can strike at the very roots of the democratic values of the LGDA system. Without effective, innovative, creative and committed leadership, all anti-poverty strategies may just plug in superficial solutions rather than tackle the root of the problem, namely governance crises in WSAs. Accordingly, 'good enough governance' or radical restructuring of the recruitment, selection and deployment policy in the current water crisis in the Northern Cape should act as a "decontaminator or antiseptic in a germ-infested area" (Cloete 2006:6-19). To extend the analogy further in terms of good enough water governance, the selection, recruitment and deployment of appropriately qualified representatives in bulk water infrastructure planning and development may lead to long-term hydropolitical adaptive capacity to respond proactively to water scarcity in the Northern Cape whereby a discernible set of water governance values and principles will benefit all citizens. Using mixed methods, the researcher found that comparative literature evidence clearly underscores the importance of effective leadership by competent and skilled councillors in water portfolios. It is also significant that academic and independent studies have ignored the oversight role of councillors in water governance. The debates only focus on officials who do not have executive powers under the new LGDA and its administration system. Yet, the current water crisis, extreme weather conditions, climate changes, and protests against poor service delivery provide an opportunity to rethink water governance. The dissertation argues that councillors in water portfolios should have minimum engineering and technical qualifications and that they need to be empowered to be adaptive and apply modern technology solutions. Any reform effort is doomed if this aspect is not addressed sufficiently well in the water sector, as it has been established in this dissertation that there is a clear link between effective leadership and excellent water governance and management. The study is not intended to be prescriptive nor can it claim to be exhaustive, as the researcher continually discovered. In many instances, it may introduce water governance complexities under a LGDA administration and political management system that are unwarranted – and misplaced idealism is always a problem. Thus, for water services to remain a viable "instrument of humanity" especially at a municipal level, it is concluded that more effective competency-based water councillor education and training (CBWCE&T) programmes are required to equip current and future councillors with the water governance skills and intellectual competencies to address the complex challenges they face. The essence of the CBWCE&T is that developmental water services need to engage in a broader governance agenda integrated with other basic services and mutually reinforcing areas of social adaptive capacity to water scarcity under the LGDA. Researchers in the water sector have neglected the hydropolitical role of councillors in determining water governance and the use of water for socioeconomic and developmental outcomes now subsumed under various poverty eradication policies. The unique contribution of this dissertation is that it focuses on this critical role of councillors and the skills they need to execute water governance institutional oversight role. The researcher makes recommendations for enriching the hydropolitical sociology of local government studies, to match the skills requirements, given the complexity of the LGDA and the numerous challenges for councillors in WSAs in the Northern Cape. / AFRIKAANSE OPSOMMING: Hierdie studie beskryf en ontleed die waterregerings- en ontwikkelingswaterdienste onderwys- en opleidingsbehoeftes van raadslede betrokke by waterdienste owerhede (WSAs) in die Noord-Kaap provinsie wat hulle in staat sal stel om hulle verantwoordelikhede na te kom soos vereis deur die wetlike raamwerk van die nuwe bedeling in Suid-Afrika. Die nuwe Suid-Afrikaanse Grondwet het 'n wetlike raamwerk ingelei wat ontwikkelingswatervoorsiening en sanitasie geriewe, synde basiese dienste, erken as plaaslike owerheidsaangeleenthede; dit funksioneer ook terselfdertyd ingevolge 'n soortgelyke wetlike bevoegdheid op nasionale en provinsiale vlak. Die Wet op Waterdiensteverskaffing, Nr 108 van 1997, asook verskeie daaropvolgende wette deur die Parlement vorm die ruggraat van die plaaslike owerheidsontwikkelingsagenda (LGDA), of te wel, die modernisasie van plaaslike owerheid, in Suid-Afrika. Hierdie wette en beleide het gesamentlik die LGDA bepaal en die afskeid toenemend gekenmerk van 'n seleksie, rekrutering, en aanwending van raadslede wat sonder minimum ingenieurs- en tegniese vaardighede in water- en infrastruktuurbeplanning en -ontwikkeling hul portefeuljes beoefen. Hierdie verwikkelings plaas sonder uitsondering nuwe leierskapsverantwoordelikhede op 'n spektrum van hidropolitieke raadslede in WSAs. Dit skep ook die behoefte aan 'n hergedefinieerde model vir verteenwoordiging deur raadslede wat volgens Sartori (1968: 465) verander van "ooreenkoms na openbare vermoë, aanspreeklikheid en reagerend". Die huidige stoffasie en soort raadslede wat water protefeuljes beklee en die infrastruktuurbeplanning en ontwikkeling laat die gedagte ontstaan dat die land 'n leierskapskrisis tegemoet gaan wat die demokratiese waardes onderliggend tot die LGDA stelsel kan ondergrawe. Sonder doeltreffende, vernuwende, skeppende en toegewyde leierskap mag die teen-armoede strategieë kunsmatige oplossings bied eerder as om die wortel van die probleem aan te durf, naamllik die regeringskrisisse in WSAs. Gevolglik moet 'goeie regering' wat neerkom op radikale herstukturering van die beleid van rekrutering, seleksie, en aanwending in die huidige waterkrisis in die Noord-Kaap geaktiveer word om te dien as 'n "ontsmetter of antiseptiese middel in 'n kiem-besmette gebied" (Cloete 2006: 6-19). Om die analogie van 'goeie waterregering; verder te neem, kan gesê word dat die seleksie, rekrutering en aanwending van toepaslik gekwalifiseerde verteenwoordigers in massa waterinfrastruktuur- beplanning en -ontwikkeling mag lei tot 'n langtermyn hidropolitieke aanpassingsvermoë om proaktief te reageer op waterskaarsheid in die Noord-Kaap waardeur 'n onderskeidende stel waterregering waardes en beginsels alle burgers sal bevoordeel. Met die gebruik van gemengde metodes het die navorser bevind dat getuienis afkomstig van vergelykende literatuuroorsigte duidelik die belangrikheid van doeltreffende leierskap deur bevoegde en vaardige raadslede in water portefeuljes onderstreep. Dit is ook betekenisvol dat akademiese en onafhanklike studies die oorsigrol van raadslede in waterregering geïgnoreer het. Die debat konsentreer slegs op amptenare wat nie uitvoerende magte binne die LGDA en die administrasie het nie. Tog is dit duidelik dat die huidige waterkrisis, uiterste weerstoestande, klimaatsverandering, en proteste teen swak dienslewering geleentheid bied tot 'n herbedink van waterregering. Die proefskrif voer aan dat raadslede oor minimum ingenieurs- en tegniese kwalifikasies moet beskik en dat hulle bemagtig word om aanpassend te wees en moderne tegnologiese oplossings kan toepas. Enige hervorming sal tot mislukking gedoem wees indien hierdie aspekte nie voldoende in die water sektor aangespreek word nie. Dit is vasgestel in die proefskrif dat daar 'n duidelike skakel is tussen doeltreffende leierskap en uitmuntende waterregering en –bestuur. Soos voortdurend ontdek is in die verloop van die navorsing, is die studie nie voorskriftelik, en ook nie uitputtend nie. In vele opsigte bied die studie kompleksiteite aan in waterregering binne 'n LGDA administrasie en politieke bestuurstelsel wat verregaande is; en misplaaste idealisme is altyd 'n probleem. Daarom, vir waterdienste om 'n lewensvatbare 'instrument van menslikheid' te bly veral op die munisipale vlak, is die gevolgtrekking dat meer doeltreffende, bevoegdheidsgebaseerde waterraadslid onderwys en opleiding programme (CBWCE&T) vereis word. Hierdie programme het die oogmerk om huidige en toekomstige raadslede toe te rus met waterregeringsvaardighede en intellektuele bevoegdhede om die komplekse uitdagings wat hulle in die gesig staar, die hoof te bied. Die essensie van die CBWCE&T program behels dat, volgens die LGDA, ontwikkelingswaterdienste sal koppel met die breër regeringsagenda wat ander basiese dienste integreer met die uitdaging van waterskaarsheid deur sosiale aanpassingsvermoëns wat onderlinge ondersteuning vir die verskillende dienste aanbied. Navorsers in water sektor het die hidropolitieke rol van raadslede verwaarloos deur nóg aandag te gee aan hoe raadslede inhoud aan waterregering gee, nóg die gebruik van water vir sosio-ekonomiese en ontwikkelingsdoeleindes soos dit tans ingesluit in verskeie armoede-uitwissingsbeleide, te beklemtoon. Die besondere bydrae van die proefskrif is die beklemtoning van hierdie kritieke rol van raadslede en van die vaardighede wat hulle benodig om 'n institusionele oorsigrol in waterregering te vervul. Die navorser maak aanbevelings vir die verryking van die hidropolitieke sosiologie van plaaslike regeringstudie, om die vaardigheidsvereistes te ontmoet in die lig van die LGDA kompleksiteite en die talle uitdagings in WSAs in die Noord-Kaap.

Thesis (MBA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Providing basic access to water and sanitation is critical for poverty alleviation and stimulating economic growth, but at the same time it is putting a huge strain on South Africa’s existing economic infrastructure. Local governments allow their existing wastewater infrastructure to deteriorate to the extent that it no longer functions according to its design, and then apply for capital funding for refurbishment. Capital investment alone will not provide a sustainable solution to meet the increased demand on the ageing wastewater infrastructure, since local governments do not have the financial means and technical capacity to adequately maintain and operate their infrastructure. A paradigm shift is required to develop alternative and innovative business models to ensure a sustainable solution providing continued and consistent capacity as a basis for further expansion. Public-private partnerships (PPP) could provide a feasible solution towards building a sustainable technical capacity at local governments. Engaging the private sector must however not be aimed towards access to private sector finance, but rather the improvement in operational efficiency and increased level in service. Obtaining private sector finances will be the wrong focus for engaging in PPP undertakings in South Africa. Private operation must be combined with public financing. The design-build-operate (DBO) model with public financing would be highly viable. Such an arrangement will hold no financial risk to the private sector entity with revenue collection strictly remaining a local government function. The DBO method of delivery (with public funding) will be an effective way to realize cost savings, achieve efficiencies in construction and operation, utilize expertise, and most importantly, for skills transfers and capacity building at local government level. Ultimate sustainability will only be achieved once local government is able to raise the majority of its own funds for operation and maintenance through tariffs and other instruments, including some towards capital redemption. Grant funding must make provision for maintenance and operation of all capital funded projects. All shareholders must join forces in lobbying this concept at the highest political echelons because in terms of Section 154 of the Bill of Rights, national and provincial governments have a duty towards local governments to support and strengthen their capacity, to effectively perform their functions.

Dissertation (PhD)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: Municipal water distribution maintenance is very important for sustainable urban development. Water pipe breaks result not only in a disruption in service but also in significant loss of water, which otherwise could have been sold to the consumer. In countries where water is scarce, such as South Africa, water losses can be detrimental to the living standard of people. Water pipe breaks can furthermore cause extensive damage to nearby lower-lying properties. Existing decision support systems available in the field of water distribution system maintenance are mainly focused on leak detection and pipe rehabilitation/replacement strategy. These existing systems, however, do not address the actual causes of pipe breaks and pipe break impact is also not supported. The aim of this research is to develop a spatial decision support system (SDSS) for pipe break susceptibility analysis and impact assessment. The engineer (or public works administrator) can apply the SDSS to model the complex pipe break phenomena in the municipal water distribution system. The SDSS can identify pipes susceptible to breaking and pipes with potentially high break impact as far as water loss and damage caused to nearby property are concerned. This combined pipe break susceptibility analysis and potential impact assessment should promote more informed decision-making on preventative maintenance measures to be taken and their prioritisation. The dissertation consists offive parts. In the first part (Chapters 1-4) theories on information systems, fuzzy logic, object-oriented modelling, Unified Modelling Language (UML) and pipe break causes are presented. This literature review provides a basis on which the SDSS for pipe break susceptibility analysis and impact assessment can be developed. In the second part (Chapter 5) the general user requirements and design of the SDSS are given. The general SDSS architecture, the general system functionality and the user interface are described and designed in this part of the dissertation. The third part (Chapter 6) provides the detailed user requirements and design of the subsystems of the SDSS. Specialised functionality for pipe break susceptibility analysis and impact assessment is added to the general design of the SDSS. Subsystems are designed for analysing the pipe break susceptibility due to age, air-pocket formation and tree-root attack. Pipe break impact assessment subsystems are also designed for assessing water loss and potential damage caused to nearby property. Finally, a combined analysis subsystem is designed for combined pipe break susceptibility analysis and impact assessment. In the fourth part (Chapter 7), the SDSS is applied to the water distribution system of the Paarl Municipality to identify pipes in the network that have both high break susceptibility and also high break impact. The pipe break susceptibility analysis model of the SDSS is also tested and calibrated by comparing the model results with actual pipe break occurrence data of the study area. The final chapter (Chapter 8) contains the summary and recommendations regarding the functionality of the newly developed SDSS. / AFRIKAANSE OPSOMMING: Die instandhouding van munisipale waterverspreidingstelsels is uiters belangrik vir volhoubare stedelike ontwikkeling. Waterpypbreuke lei nie alleenlik tot onderbreking in diensverskaffing nie, maar ook tot beduidende waterverlies en verlies aan inkomste uit waterverkope. In lande waar water skaars is, soos in Suid-Afrika, kan waterverliese die lewenstandaard van die bevolking nadelig beïnvloed. Waterpypbreuke kan ook groot skade aan naby-geleë laag-liggende eiendomme aanrig. Besluitnemingstelsels tans beskikbaar op die gebied van instandhouding van waterverspreidingstelsels is hoofsaaklik gerig op lekkasie-opsporing en pyprehabilitasie- en pypvervangingstrategieë. Hierdie bestaande stelsels spreek egter nie die eintlike oorsake van pypbreuke aan nie, daar word ook nie op die impak van pypbreuke ingegaan nie. Die doelwit van hierdie navorsing is om 'n ruimtelike besluitnemingstelsel (RBS) - vir pypbreuk-risiko-analise en impakberaming te ontwikkel. Die ingenieur (of stelselbestuurder) kan met behulp van die RBS die komplekse pypbreukverskynsel in 'n munisipale waterverspreidingstelsel modelleer. Die RBS kan pype met hoë breek-potensiaal identifiseer asook pype wat, indien dit breek, groot waterverlies of skade aan naby-geleë eiendomme sal veroorsaak. Hierdie gekombineerde pypbreuk-risiko-analise en impakberaming behoort meer oordeelkundige besluitneming te bevorder deur beter prioritisering van voorkomende instandhoudingsmaatreëls en die uitvoering daarvan. Die proefskrif bestaan uit vyf dele. In die eerste deel (Hoofstukke 1-4) word die teorieë oor inligtingstelsels, 'fuzzy logic', objek-georiënteerde modellering, 'unified modelling language (UML)' en die oorsake van pypbreuke behandel. Hierdie literatuurstudie skep die basis waaruit die RBS vir pypbreukrisikobepaling en impakberaming ontwikkel sal word. In die tweede deel (Hoofstuk 5) word die algemene gebruikersbehoeftes en die ontwerp van die RBS uiteengesit. Die algemene RBS struktuur en die gebruikerskoppelvlak word in hierdie deel van die proefskrif beskryf en ontwerp. In die derde deel (Hoofstuk 6) word die gedetailleerde gebruikersbehoeftes en die ontwerp van die substelsels van die RBS uiteengesit. Gespesialiseerde funksionaliteit vir pypbreuk-risikobepaling en impakberaming is tot die algemene ontwerp van die RBS bygevoeg. Substelsels is ontwerp vir die ontleding van pypbreuk-risiko as gevolg van ouderdom, lugblaas-vorming en boomwortelaanval. Substelsels vir impakberaming is ook ontwerp om waterverlies en potensiële skade aan eiendomme vas te stel. Ten slotte word 'n gekombineerde ontledingsubstelsel vir gekombineerde pypbreuk-risikobepaling en impakberaming opgestel. In die vierde deel (Hoofstuk 7) word die RBS toegepas op die waterverspreidingstelsel van die Paarlse munisipaliteit om pype uit te ken wat beide 'n hoë breuk-risiko en 'n hoë breuk-impak bevat. Die pypbreuk-analise model van die RBS is ook getoets en gekalibreer deur die resultate van die model te vergelyk met data van werklike pypbreuke in die studiegebied. Die laaste hoofstuk (Hoofstuk 8) bevat die samevatting en die aanbevelings rakende die funksionaliteit van die voorgestelde RBS.

Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: South African water service providers experience major problems with providing adequate water services to consumers. Water service providers in South African urban areas rely on traditional centralised infrastructure, such as bulk supply networks, to provide water services. Alternative supply and stormwater drainage methods should be encouraged to help mitigate these problems. The researcher thus aims to quantify the potential impact that three alternative methods may have on a given dwelling in terms of its dependence on traditional bulk water services. The three alternatives considered in this thesis are the construction of green roofs, rainwater harvesting and greywater re-use. An efficiency of dwelling water use index (EDWI) was developed during this research project. It was designed in such a way as to show what portion of municipal water services could be replaced within the given dwelling by using the proposed techniques. The final EDWI-rating is obtained by using the EDWI-software tool developed as a part of this research. The derived EDWI-rating ranges from 0 to 100, with a rating of 100 indicating a dwelling requiring only the removal of a portion of sewage by a municipality, but no external water supply. Such a dwelling would also not require any water from a municipal network to meet domestic demand and all stormwater from its roof would be utilised within the plot boundaries. Results presented in this thesis illustrate how different geographical regions require different system specifications to obtain optimal EDWI-ratings, thereby lowering their dependence on the respective municipal water services. Validation of the EDWI-system proved difficult as no similar index could be found during the literature review. It was therefore decided to benchmark the EDWI-system using three model dwellings with nine configurations producing a total of 27 analyses. The EDWI-system provides a conceptual foundation for sustainable water services to South African households in serviced urban areas. Future work could further improve the EDWI-system by testing its practical application so that it may be extended to act as a national barometer, used to compare decentralised water services in terms of sustainability. / AFRIKAANSE OPSOMMING:Suid-Afrikaanse waterdiensverskaffers ondervind groot probleme met die voorsiening van voldoende waterdienste aan verbruikers. Waterdiensverskaffers in Suid-Afrikaanse stedelike gebiede maak staat op tradisionele gesentraliseerde infrastruktuur, soos grootmaatvoorsienings netwerke, om waterdienste te verskaf. Alternatiewe voorsienings- en stormwater dreineringsmetodes moet aangemoedig word om hierdie probleme aan te spreek. Die studie poog dus om die potensiële impak wat drie alternatiewe moontlikhede kan hê op 'n gegewe woning in terme van sy afhanklikheid van die tradisionele waterdienste te kwantifiseer. Die drie alternatiewe moontlikhede wat in hierdie studie ingesluit word is die konstruksie van groendakke, reënwater oes en grys water hergebruik. 'n Huishoudelike water gebruik doeltreffendheids indeks (EDWI) is ontwikkel gedurende hierdie navorsingsprojek. Die indeks is ontwerp om aan te dui watter gedeelte van munisipale waterdienste deur die voorgestelde tegnieke vervang kan word. Die finale EDWI-gradering is verkry deur gebruik te maak van die EDWI-programmatuur wat ontwikkel is gedurende die navorsing. Die afgeleide EDWI- gradering wissel tussen 0 en 100, met 'n telling van 100 wat ‘n woning voorstel wat slegs die verwydering van 'n gedeelte van die riool deur die munisipaliteit vereis, maar wat geen eksterne watervoorsiening benodig nie. So 'n woning vereis dus geen water van ‗n munisipale netwerk nie, en alle stormwater van die dak word binne die erf gebruik. Resultate wat in hierdie studie voorgelê word illustreer hoe verskillende geografiese streke ander stelsel spesifikasies vereis om optimale EDWI-gradering te verkry. Die navorser kon geen indeks kry wat soortgelyk is aan die EDWI-stelsel om dit mee te vergelyk nie. Dit was gevolglik besluit om die indeks te standardiseer deur gebruik te maak van drie model huise met nege samestellings van alternatiewe, waardeur 27 ontledings ontwikkel was. Die EDWI-stelsel bied 'n konseptuele grondslag vir volhoubare waterdienste vir Suid-Afrikaanse huishoudings in gedienste stedelike gebiede. Toekomstige navorsing kan die EDWI-stelsel verder verbeter deur die praktiese toepassing te toets. Die stelsel kan uitgebrei word om ‗n nationale barometer vorm wat gebruik kan word om desentralisasie van waterdienste te meet in konteks van volhoubaarheid.

Thesis (MEng)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: The Berg River is one of the largest rivers in the winter rainfall area of the Western Cape and is one of the most important water supply sources of the area. The Riviersonderend-Berg system needs to be expanded in order to meet increasing water demands of the Greater Cape Town (GCT) region. The implementation of future schemes will remove additional fresh water from the Berg River main stem, which will give rise to increased nutrient levels and higher salinity in the water. A water quality information system (WQIS) has been proposed to benefit the management of water resources, the flow quantity and the quality of the water. A part of this WQIS will be a water-quality simulation model that characterizes the water quality situation and is able to predict water quality responses to future implementations, as well as simulate different scenarios that can be used for management purposes. The objective of this study is to represent the water quality situation of the Berg River in a simulation model by implementing, testing and verifying a water quality simulation model, and assembling a hydraulic and water quality database suitable to meet foregoing objectives. This study firstly examined the water quality variables of concern: pH, Total Dissolved Salts (TDS) and phosphates to develop an understanding of the water quality responses and causes of the main stem of the Berg River system. A thorough review of the available models has been undertaken in the light of certain selection criteria, before determining that DUFLOW would be an acceptable model for this study. The water quality variables that have been modelled are TDS, Phosphates as P04, Oxygen and Temperature. As no predefined module simulating temperature, TDS and COD was included; these algorithms, describing the processes of these water quality variables have been additionally coded. The coding was possible, as DUFLOW' s water quality module consists of an open structure. The predefined water quality module was simplified to only include the water quality process algorithms, for water quality variables where data was available. Unfortunately, phosphates were mainly simulated on advection, and the influence of all the additional processes could not be assessed. All data gathering and preparation for the model had to be completed before commencing the model configuration. This included information on cross-sections, historical flow records, bridges and weirs for the hydraulic component ofDUFLOW. For the water quality module, information on historical grab samples has been obtained and 'infilled' to provide daily time series. To simulate the water quality in a river as accurately as possible, the flow simulation needs to be accurate. Ungauged subcatchment runoff was added to the simulation model to improve the correspondence between the simulated and the measured flow. Calibration of the water quality part of DUFLOW was completed by adjusting the different parameters after a sensitivity analysis. The model was verified by using a different time period than for the configuration, to ensure that an independent data set has been used. After configuring, calibrating and verifying the model, the applicability of the model could be tested for different scenario runs. Three scenarios were chosen according to real situations: • a short term effluent spill, with and without water releases from an upstream source (either Skuifraam Dam or Voëlvlei Dam); • the impact on the flow and water quality situation of the river when an upstream dam is built; • a long term management control scenario, that analyses load or concentration releases into the river according to limitations upstream and downstream of the discharge location. The scenario analysis provides an opportunity to assess the applicability of DUFLOW to simulate real time management and operational issues in a river and to aid in management decisions. / AFRIKAANSE OPSOMMING: Die Bergrivier is een van die grootste riviere in die winterreënvalgebied van die Weskaap en is een van die mees belangrike waterverskaffingsbronne in die area. Die Riviersonderend-Bergrivier-stelsel moet uitgebrei word om aan die groeiende waterbehoefte van die groter Kaapse Metropolitaanse Area te voldoen. Die implementering van toekomstige skemas sal addisionele vars water uit die hoof-loop van die Bergrivier onttrek, wat tot hoër voedingstof-vlakke en soutgehalte in die water sal lei. 'n Waterkwaliteitsinformasiestelsel (WQIS) sal van nut wees om die vloei-omvang en waterkwaliteit van waterbronne te bestuur. 'n Deel van die WQIS sal 'n waterkwaliteit-simulasiemodel wees, wat die waterkwaliteitsituasie sal kan ontleed, waterkwaliteit-reaksies op toekomstige implementerings kan voorspel, asook verskeie scenarios vir bestuursdoeleindes kan simuleer. Hierdie studie behandel spesifiek die waterkwaliteitsveranderlikes pH, totale opgeloste soute, fosfate, temperatuur en suurstof om 'n begrip te ontwikkel van die waterkwaliteitsreaksies en oorsake van die hoofloop van die Bergriviersisteem. Die doelwit van hierdie studie is om die waterkwaliteitsituasie van die Bergrivier uit te beeld deur die implementering, toets en kalibrasie van 'n waterkwaliteit-simulasie model, asook die insameling van hidrouliese- en waterkwaliteitsdata om aan bogenoemde doelwitte te voldoen. 'n Reeks beskikbare modelle is deeglik ondersoek voordat besluit is dat die DUFLOW model 'n gepaste model vir hierdie spesifieke studie is. Die keuse was gebaseer op spesifieke vereistes wat as belangrik beskou is deur potensiële bestuursgeorienteerde gebruiksgroepe. Die waterkwaliteitsveranderlikes wat gemodelleer is, is totale opgeloste soute, fosfate as P04, suurstof en temperatuur. Omdat geen voorgegewe temperatuur-, TDS- en COD modules in die model ingesluit is nie, is die algoritmes wat die prosesse van hierdie waterkwaliteitsveranderlikes beskryf, addisioneel gekodeer. Die kodering is moontlik gemaak deur die oop struktuur van DUFLOW se waterkwaliteitsmodule. Die voorgegewe waterkwaliteitsmodule is vereenvoudig om alleenlik die waterkwaliteit proses-algoritmes in ag te neem wanneer data vir waterkwaliteitsveranderlikes beskikbaar was. Ongelukkig is die fosfate hoofsaaklik op beweging gesimuleer, en die invloed van alle addisionele prosesse kon nie getoets word nie. Alle data-insameling en -voorbereidings vir die model moes voltooi word, voordat begin kon word met die opstel van die simulasie-model. Dit het inligting oor dwarssnitte, historiese vloeirekords, brik en keerwalle vir die hidrouliese komponent van DUFLOW ingesluit. Vir die waterkwaliteitsmodule is inligting van historiese bemonstering verkry en ingevulom 'n daaglikse tydreeks te verkry. Om die water-kwaliteit van 'n rivier so akkuraat as moontlik te simuleer, moet die vloei-simulasie redelik akkuraat wees. Ongemete sub-opvanggebied afloop is bygetel om die korrelasie tussen die gesimuleerde en gemete vloei te verbeter. Kalibrasie van die waterkwaliteitmodule van DUFLOW is voltooi deur die verskillende parameters te verstel na 'n sensitiwiteits-analise. Die model is geverifieer deur 'n ander tydperiode as die vir die opstel te gebruik, om sodoende te verseker dat Inonafhanklike data stel gebruik word. Na die opstel, kalibrasie en verifiering van die model, kon dit toegepass word vir verskillende bestuursscenanos. Drie scenarios is na aanleiding van werklike situasies gekies: 'n korttermyn uitvloeisel storting-situasie met en sonder loslatings van 'n stroomop bron (Of Skuifraamdam Of Voëlvleidam), die impak op die vloei- en waterkwaliteitsituasie van die rivier sou 'n dam stroomop gebou word. 'n langtermyn bestuurs-scenario waarin die lading en konsentrasies, veroorsaak deur die loslatings vanuit die dam na die rivier, ontleed word na aanleiding van beperkings stroomop en -af van die loslatingsplek. Die analise van die scenarios verskaf 'n geleentheid om die toepaslikheid van DUFLOW te ondersoek om werklike operasionele aangeleenthede te simuleer en om sodoende bestuursbesluite te vergemaklik.

The Table Mountain group aquifer system has the potential to be an important supply of water. Although the aquifer system is used to some extent, a number of aspects relating to the aquifer system are poorly understood and unquantified. This study aimed to take into consideration the importance of differenct ecosytems, which is essential in predicting the effects of groundwater abstruction. However, the ecological requirements of systems that depend on groundwater are poorly understood. This project identified &quot / type areas&quot / for further detailed research into the impacts of large-scale groundwater abstraction from the Table Mountain group aquifer system based on the nature and functioning of ecosystems across groundwater dependent ecosystem boundaries of a regional scale.

South Africa has one of the highest levels of inequality in the world, and the government has attempted to redress extensive material, social and political deprivation. It has been confronted by the tension between the need for rapid delivery of essential services and the aspiration for people-centred development. Limited resources and insufficient capacity have led the state to contract out service provision to the private sector. There has also been a shift toward self-sufficiency which has placed pressure on service users to manage their own development. 'Public-private Partnerships' have come to be a common feature of many development projects. These partnerships must be understood in relation to prevailing conditions within South Africa. Extensive poverty, social turbulence, an unaccountable state bureaucracy particularly in local government, and vested interests which do not support the goals of redistribution envisaged in the constitution all exist. Public-private partnerships are relatively new to South Africa. Four issues were raised about these relationships: Will they lead to the promotion of efficient and effective service delivery? Do they promote good governance? Is there a specific role for NGOs in public-private partnerships and finally what are the conditions for genuine participation by local communities within public-private partnerships? A study of public-private partnerships in the water sector, involved in the Community Water Supply and Sanitation Programme was undertaken. A variety of research methods, notably formal and semi-formal interviews and focus group discussions were employed to explore these relationships. Fieldwork was conducted between November 1998 and January 1999. The research involved familiarisation with new South African policy legislation which is set to alter the entire institutional environment. The study also drew upon international literature in order to assess the influence of global changes upon the water sector in South Africa, and also to locate the forms of water service provision within broader theoretical contexts. The key organisations which were investigated, and those which played a role in the Community Water Supply and Sanitation Programme were: the Department of Water Affairs and Forestry; the Mvula Trust, a large national non government organisation (NGO); various water committees supported by the Mvula Trust; and the Build, Operate, Train and Transfer (BOTT) consortia, which are joint ventures between the Department of Water Affairs and Forestry (DWAF), private firms and the Mvula Trust. Turning first to the question of the efficiency and effectiveness of public-private partnerships in service delivery, the findings of this study reveal that there are gaps in service delivery in the water sector which are not being filled by public-private partnerships. Poor performance by project managers, cases of exploitation by project and training agents of community organisations, and insufficient accountability (especially on the BOTT projects) towards the water users, are widely in evidence. Key leadership and managerial functions within these ventures are missing. The findings of the study reinforce the need for the state to play an active role in managing and leading public-private partnerships. The second issue concerning the relationship between public-private partnerships and good governance, reflects confusion in state priorities. The Water Services Act stipulates the importance of local government managing water service provision. Yet public-private partnerships currently bypass this level of governance. Turning to the third issue of the role for NGOs in public-private partnerships, it could be argued that like other NGOs in South Africa Mvula has to deal with various contradictions. In many ways it operates as a parastatal, not as an NGO. Mvula is dependent on the state for funding, the recent funding crisis has highlighted the dangers of such reliance upon the state, and Mvula can be criticised for being short sighted and too trusting. It has also meant that Mvula has had to adopt DWAF's policy objectives which differ markedly from those of the Trust. At another level, though, Mvula's ability to introduce innovative approaches to water service delivery and to influence policy on water service delivery proves that there are ways in which state and non-state actors can engage in useful relationships. The debate about participation has also been woven into the discussion about public-private partnerships. The basis for public-private partnerships in South Africa has been that local communities would manage their own development processes. Radical participation has been entrenched both in the constitution of SA and in the goals of the RDP. Yet none of the actors (even the Mvula Trust) promote radical participation. At best a watered down version based on community consultation was applied, although in numerous projects participation was token. For the foreseeable future participation will remain a central element of service delivery. Service providers will have to allocate more resources and time toward supporting community organisations to manage their own development. This in tum will increase the costs of service delivery. In the long term these functions should be handed over to local government, in order that rural dwellers may concentrate on their livelihoods. The most critical project in the next ten to fifteen years will be to build strong local government. The biggest challenge will be to change the organisational mindset of these presently conservative and weak structures. A theme, which has underpinned this dissertation, has been the debate between efficiency and equity. Questions remain as to whether it was possible to reconcile these perhaps conflicting goals. In essence: was it possible for public-private partnerships to deliver basic services, both speedily and by redistributing resources to the poorest. This research has found that public-private partnerships in the water sector have failed to excel with either of these goals. The Mvula trust is concerned with the participation of the poorest, yet these projects are much slower than the services provided by the BOTT consortia. The BOTT consortia are able to undertake rapid service delivery although there is limited involvement by local communities, which in turn threatens the long-term sustainability of the BOTT projects. The lessons to be learnt from this case study are that privatisation and the contracting out of state services need to be accompanied by the simultaneous development of strong institutions. These include NGOs, CBOs, private contractors and local and national state institutions. / Thesis (M.A.)-University of Natal, Durban, 1999.

A research report submitted to the faculty of Commerce, Law and Management, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Management (in the field of Public and Development Management) March 2015 / The citizen science approach has a role to play in the restoration of river health in catchments affected by pollution. Everyone can become involved in monitoring the health of a river, dam, estuary or wetland closest to them. In KwaZulu-Natal, uMngeni and Msunduzi Catchments, voluntary participation in river health initiatives has been adopted by schools, conservancies, NGOs and catchment management forums. The purpose of the study was to explore the perceptions and experiences of the use of miniSASS, a simplified South African Scoring System (SASS) tool for monitoring river health in uMngeni and Msunduzi Catchments over the past 15 years. A qualitative exploratory and descriptive study was undertaken through semi-structured interviews and documentary analysis. The researcher managed to purposively select a sample of ten participants, mainly the active users of the miniSASS citizen science tool in the identified catchments. The finding of the study is that miniSASS is perceived and experienced as a valuable community-based educational tool in Msunduzi and uMngeni catchment which has led to local government authorities to respond faster in solving incidents of industrial pollution; address poorly maintained water infrastructure and fix the leaking sewers contaminating freshwater. The study recommends that a further investigation be made on the economic value of citizen science contribution in KwaZulu-Natal since there were indications that it has already benefited some of the accommodation businesses who appreciated the change in the nearby streams.

Thesis (MTech (Public Management))--Cape Peninsula University of Technology, 2019. / The research provides a broad overview of the problem statement, research objectives, demarcation of the research, research methodology, and significance of the research, a brief literature review and the ethics statement. Theoretical background through a literature review of the selected topic, as well as of the legal frameworks that guide the provisioning of sanitation. The researcher consulted literature that describes the provisioning of sanitation by the City of Cape Town, and the challenges it faces in this regard. The researcher also discussed the legislation that guides sanitation, and five broad themes relating to sanitation, around which the research questions were formulated. The researcher discovered that City of Cape Town employees face a number of challenges that make their job difficult, especially in providing water and sanitation to the communities in Site C in Khayelitsha. The researcher concludes the study and makes recommendations regarding the provision of proper sanitation by the City of Cape Town. These recommendations are based on the study's questionnaire results
