Africa particularly has been experiencing the world’s most rapid rate of urbanization and cities are faced with the resulting pressure on natural resources. Water is one of the resources under pressure and the provision thereof is complicated by the deteriorating quality and quantity thereof. This study takes a brief look at the water situation in a water scarce region in Africa and concentrates on the urban water supply sector. It takes an in depth look at the measures used to secure water supply to a city in this very dry part of the world. The area under study is Windhoek, the capital of Namibia, situated in the southwestern corner of Africa. Namibia is the driest country in Sub-Saharan Africa and is characterised by a semi-arid nature, which results in a very hot and dry climate with erratic rainfall patterns. Windhoek has a low average rainfall associated with very high evaporation rates. No permanent water bodies exist near the city and the bulk of Windhoek’s water supply comes from storage dams quite a distance from the capital. Most of these sources of supply have been developed and are nearing the limit of their potential. A desperate need therefore exists to develop reliable additional water resources to secure the water supply especially during periods of prolonged drought. The case study gives examples of the initiatives taken by water authorities to improve the security of supply and keep up with the growing demand in the city. These initiatives include a dual pipe system for the distribution of semi-purified sewage for irrigation, reclamation of domestic sewerage, aquifer recharge and the implementation of Water Demand Management principles. An analysis of the most efficient and cost-effective means of supply augmentation namely aquifer recharge, have been balanced against the potential water savings of Water Demand Management in the city. The study also takes a brief look at the principles of Integrated Water Resource Management and how it is incorporated in the strategies used to augment supply to the city. The research found aquifer recharge as the most efficient and cost-effective means to augment supply to the city and together with Water Demand Management creates an approach complying with the goals of Integrated Water Resource management. The study concludes by identifying gaps in demand management in the city. It also suggests relevant recommendations on how to increase the effectiveness of Water Demand management.
AFRIKAANSE OPSOMMING: Verstedeliking is ‘n komplekse verskynsel en ‘n tendens wat regoor die wêreld voorkom. Die hoogste voorkoms van verstedeliking vind in Afrika plaas wat groot druk plaas op die natuurlike hulpbronne van stede. Water is een van die hulpbronne onder druk en die voorsiening daarvan word bemoeilik deur die verswakking van die kwaliteit en die beskikbaarheid daarvan. Hierdie studie konsentreer op die watersituasie in ‘n waterskaars streek in Afrika en die stedelike watervoorsieningssektor. Dit behels ‘n in diepte ondersoek na metodes wat gebruik word om die watervoorraad van die stad te verseker in hierdie droogte gesteisterd deel van die wêreld. Die gebied onder bespreking is Windhoek, die hoofstad van Namibië, wat geleë is in die Suidwestelike deel van Afrika. Namibië is die droogste land in die Sub-Saharastreek en word gekenmerk deur gereelde droogtes met ‘n gepaardgaande warm droë klimaat en onreëlmatige reënvalpatrone. Windhoek word gekenmerk deur ‘n lae gemiddelde reënval met ‘n baie hoë verdampingstempo. Geen permanente waterbronne kom in die nabyheid van die stad voor nie en die watervoorraad word gestoor in opgaardamme wat redelik ver van die hoofstad geleë is. Hierdie voorsieningsbronne is voortdurend in gebruik en die voorraad is beperk. Daar onstaan dus ‘n dringende behoefte aan betroubare bykomende waterbronne om voortdurende voorsiening aan die stad te verseker veral gedurende aanhoudende droogtes. Die gevallestudie konsentreer op voorbeelde en inisiatiewe wat deur die Water Owerhede geneem word om die voorsiening van water, aan die immergroeiende behoeftes van die stad te verbeter en te verseker. Hierdie pogings sluit in,‘n dubbele pyplynsisteem vir die verspreiding van halfgesuiwerde rioolwater vir besproeiingsdoeleindes, herwinning van huishoudelike rioolwater, herlaai van ondergrondse watervoorraad en die implimentering van wateraanvraag bestuursmaatreëls. Die geskiktste en mees koste-effektiewe metode van verhoogde watervoorsiening naamlik die herlaai van ondergrondse waterbronne, is ontleed, en die voordele opgeweeg teen die potensiële waterbesparing deur die Bestuur van Wateraanvraag in die stad. Daar is ook kortliks gekyk na die beginsels van Geintigreerde Water Bronne Bestuur en hoe dit by bestaande strategieë ingelyf is om uitbreiding van voorsiening aan die stad te verseker. Die navorsing het bevind dat die herlaai van ondergrondse waterbronne as die geskikste en mees koste-effektiewe metode beskou kan word om die verhoogde aanvraag van die stad die hoof te bied. Die studie word afgesluit deur die tekortkominge in die Water Aanvraagbestuur van die stad te identifiseer. Relevante aanbevelings word gemaak van hoe om die effektiwiteit van hierdie betrokke strategie te verbeter.

Повний текст джерелаThis study gives an overview of the sustainability of potable water supply in rural areas of South Africa in general and four rural areas of uMhlathuze in particular. Three key challenges in achieving sustainable rural water supply are discussed in more detail and later on used to evaluate the inadequacy of financial revenues to cover the full operation, maintenance and replacement of infrastructure. This research study analysed the factors pertaining to the tariff structure used in maintaining and sustaining rendered service. It analysed the current tariff structure that includes the poorest and most marginalised in line with revenue needed to cover recurrence costs. It was the purpose of this study to examine the adequacy of the management system used to sustain the supply of potable water in rural areas, taking into cognisance the costs of rendering the account and of illegal connections combined with high water losses. The study also attempted to link these points to the challenges faced by the rural areas. The sustainability of rural water supply was analysed, based on financial factors, affordability and on the willingness to pay for the service. The researcher first compared the water billing (levies) and payment patterns of each customer in rural areas of uMhlathuze Municipality with others; and secondly, compared the primary data against theory and the literature. Differences and similarities between the collected data and theory were at the core of the analysis The research results determined that the municipality has the capacity to maintain and sustain the potable water supply network in these areas, while dealing with management questions and recommending to management what is needed to ensure that the water reticulation system is run on a sustainable basis. Sustainability of rural water supply seems to be dependent on factors like policy, legal framework and economic factors such as an ability to meet the costs and willingness to pay for rendered service.

Повний текст джерелаENGLISH 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.

Повний текст джерелаENGLISH ABSTRACT: South African municipalities are under pressure to improve the current state of the water andwastewater service delivery industry. Knowing that there exists a need for improvement within the municipal water and wastewater industry, the Department of Water Affairs (DWA) launched a municipal strategic self-assessment (MuSSA) initiative to evaluate the business health of the industry. MuSSA asks high level technical management staff five key questions about sixteen key business attribute areas. This study seeks to determine if theMuSSA data can be used to aid municipal decision making, by way of drawing correlations between key performance indicators contained in the MuSSA questions. The correlations are to bring forth areas thatmust be focussed on to improve selected attribute areas requiring attention within municipalities. Three areas have been chosen from theMuSSA data to be investigated in this research project namely; (i)staff skill levels and capacity, (ii)non-revenue water and (iii)the execution of planned water services activities. In the MuSSA questionnaire there are questions addressing each of (i), (ii) and (iii) to determine the municipality’s performance in each of the three areas. Non-parametric statistics are used to determine with which of the MuSSA questions’ answers the relevant questions’ answers significantly correlate for (i), (ii) and (iii). Engineering judgement and expert opinion are used to determine if the questions correlating with the relevant questions for (i), (ii) and (iii) either affect, are affected by or have no relation with the question. These results are then organized using a flow diagram and are discussed in detail by way of a bivariate histogramof each correlation. The investigation revealed that municipalities not having sufficient technical management capacity are not performing well on at least one of the five questions asked on eleven of the sixteen MuSSA business attributes. The skill level of water and wastewater treatment works staff were found to be strongly affected by technical management capacity and skill, water services planning and financial sustainability of the organization. Municipalities training technical management and operational staff showed a high percentage of skilled operational staff employed at treatment works. Water and wastewater treatment works staff capacity are very dependent of the level of skill and capacity of technical management employed by the municipality. Municipalities having appropriate budgets and funding to appoint and train staff showed a tendency to be better at operational staff capacity building than those lacking funding. The reduction of non-revenue water (NRW) showed strong correlations with technical management and network operational repair staff skills and development. Municipalities employing staff with correct skills and experience combined, with commitment from management to reduce NRW by way of monitoring and practicing of pressuremanagement programs, significantly reduced NRW percentages. Equally crucial to the reduction of NRW, as revealed from the investigation, is the practicing of infrastructure asset management within the municipality. It was concluded that municipalities should strive to reach a NRW percentage of 30% or less to become financially stable, due to correlation between funding of routine operations and building up of cash reserve versus NRW percentages. Municipalities wanting to improve the execution rate of planned water services activities are recommended to address, among other factors, technical management skill levels and capacity. Municipalities lacking technical management skill and capacity reported a low percentages of planned activities being executed. Also of high significance, is the technical operational staff skill levels and capacity, due to their involvement in the execution of planned activates. The involvement of council members in water and wastewater planning and the reporting of data and issues to council greatly enhancesmunicipalities’ abilities to execute planned activities. This can mainly be contributed to increased funding in situations where council members support planned projects. The lack of funding was found to be a major inhibitor of the execution of planned activities. Even though a great deal of municipalities indicated that they are effectively spending allocated budgets, this positive indication is not seen in the percentage municipalities executing planned activities and leads to the conclusion that there is a lack of funding. Municipalities taking actions in other areas of their business such as infrastructure assetmanagement and planning were more effective at executing planned activities. In all, it was concluded that technicalmanagement and operational staff skill levels and capacity need to be present for amunicipality to function properly. Municipalities also are in need of funding to execute planned activities and need to become financially self sustainable. One way of working towards the goal of financial self sustainability is the reduction of NRW percentages. The data from this investigation shows great similarity with the literature consulted on the current state and functioning of South African municipalities. The statistical analysis of the MuSSA data accurately revealed correlations among key performance indicators in municipalities. The conclusion can be drawn that investigation of correlations amongMuSSA questions can be used to help aid municipal decision making.
AFRIKAANSE OPSOMMING: Suid-Afrikaanse munisipaliteite is onder druk om die huidige toestand van die water en afvalwater dienslewering te verbeter. Met die wete dat daar ’n behoefte vir verbetering in die munisipale water en afvalwater bedryf is het dieDepartement vanWaterwese ’n munisipale strategiese self-assessering (MuSSA) projekte geïnisieer omdie welstand van die bedryf te evalueer. MuSSA vra hoë vlak tegniese bestuurs personeel vyf kern vrae oor sestien sleutel besigheids aspekte. Hierdie studie poogomvas te stel of dieMuSSA data gebruik kan word om munisipale besluitneming te help verbeter, deur middel van die evaluering van korrelasies tussen die sleutel prestasie aanwysers soos vervat in MuSSA vrae. Die korrelasies bring na vore gebiede waar op gefokus moet word om geselekteerde kenmerk areas binne munisipaliteite, wat aandag vereis, te verbeter. Drie areas uit die MuSSA-data is ondersoek in hierdie navorsings projek naamlik; (i) personeel vaardigheidsvlakke en kapasiteit, (ii) nie-inkomste water en (iii) die uitvoering van die beplande waterdienste aktiwiteite. In die MuSSA vraelys is daar vrae wat elk van (i), (ii) en (iii) aanspreek om die munisipaliteit se prestasie op die drie gebiede te monitor. Nie-parametriese statistiek word gebruik om die oorblywendeMuSSA vrae wat se antwoorde met die relevante vrae se antwoorde korreleer vir (i), (ii) en (iii) vas te stel. Kundigheid en oordeel van ingenieurs word gebruik om te bepaal of die vrae wat korreleer met die relevante vrae vir (i), (ii) en (iii) die relevante vraag beïnvloed, beïnvloed word deur die relevante vraag of geen verhouding het met die relevante vraag nie. Hierdie resultate word dan georganiseer met behulp van ’n vloeidiagram en word in detail bespreek deur middel van ’n tweeveranderlike histogram van elke korrelasie. Die ondersoek het aan die lig gebring dat munisipaliteite wat nie genoegsame tegniese bestuurs kapasiteit het nie swak presteer op ten minste een van die vyf vrae van elf van die sestienMuSSA besigheid eienskappe. Die personeel vaardigheidsvlakke van water en afvalwater behandelings werke word sterk beïnvloed deur die tegniese bestuurskapasiteit en -vaardigheid, waterdienste beplanning en die finansiële volhoubaarheid van die organisasie. Munisipaliteite wat opleiding van tegniese bestuur en operasionele personeel uitvoer het ’n hoë persentasie van opgeleide operasionele personeel werksaam by suiweringswerke. Water en afvalwater behandelingswerke se personeelkapasiteit is baie afhanklik van die vlak van vaardigheid en kapasiteit van tegniese bestuur in diens van die munisipaliteit. Munisipaliteite met toepaslike begrotings en befondsing om personeel aan te stel en op te lei het ’n neiging om beter te presteer met kapasiteitsbou van operasionele personeel as die wat aan ’n gebrek ly van befondsing. Die vermindering van nie-inkomste water (NRW) het sterk korrelasies met tegniese bestuur en netwerkherstel personeelvaardighede en ontwikkeling. Munisipaliteite wat personeel met die korrekte vaardighede en ervaring in diens het, gekombineer met bestuur wat dit nastreef om NRW te verminder by wyse van monitering en uitvoering van druk beheer in water netwerke het aansienlik kleiner NRWpersentasies. Ewe noodsaaklik vir die vermindering van NRW, soos geopenbaar deur die ondersoek is die beoefening van interne infrastruktuur batebestuur deur diemunisipaliteit. Daar is tot die gevolgtrekking gekom dat munisipaliteite daarna moet streef om ’n NRW persentasie van 30% of minder te bereik om finansieel stabiel te word, as gevolg van die korrelasie tussen befondsing van roetine bedrywighede en die opbou van kontant reserwe teenoor NRWpersentasies. Munisipaliteitewat die uitvoeringskoers van beplande waterdienste aktiwiteitewil verbeter, word aanbeveel om onder andere, tegniese bestuurs vaardigheids vlakke en kapasiteit aan te spreek. Munisipaliteite wat nie tegniese bestuursvaardigheid en -kapasiteit het nie, berig dat ’n lae persentasie van beplande aktiwiteite uitgevoer word. Die tegniese operasionele personeel vaardigheidsvlakke en kapasiteit, as gevolg van hul betrokkenheid in die uitvoering van beplande aktiwiteite is ook van groot belang. Die betrokkenheid van lede van die raad by water en afvalwater beplanning en die rapportering van data en kwessies aan die raad verhoog baiemunisipaliteite se vermoëns om beplande aktiwiteite uit te voer. Dit kan hoofsaaklik toegeskryf word aan verhoogde befondsing in situasies waar raadslede beplande projekte ondersteun. Dit is gevind dat die gebrek aan befondsing ’n groot inhibeerder van die uitvoering van beplande aktiwiteite is. Alhoewel ’n meerderheid van die munisipaliteite aangedui het dat hulle begrotings effektief spandeer, word dit egter nie weerspieël in die persentasie munisipaliteite wat beplande aktiwiteite uivoer nie en lei dit tot die gevolgtrekking dat daar n gebrek aan befondsing is. Munisipaliteite wat klem lê op ander gebiede van hul besigheid soos, infrastruktuur batebestuur en beplanning was meer effektief met die uitvoering van die beplande aktiwiteite. Daar is tot die gevolgtrekking gekom dat tegniese bestuur en operasionele personeel vaardigheidsvlakke en kapasiteit noodsaaklik is vir ’n munisipaliteit om behoorlik te funksioneer. Daar is ook ’n behoefte aan befondsing by munisipaliteite om beplande aktiwiteite uit te voer en munisipaliteite moet finansieel onafhanklik en lewensvatbaar word. Een manier om te werk te gaan om finansiële self volhoubaarheid te bereik, is die vermindering van NRW persentasies. Die data van hierdie ondersoek toon groot ooreenkomste met die literatuur wat geraadpleeg is oor die huidige stand en funksionering van Suid-Afrikaanse munisipaliteite. Die statistiese analise van die MuSSA data het akkurate korrelasies geopenbaar tussen die sleutel prestasie-aanwysers inmunisipaliteite. Die gevolgtrekking kan gemaak word dat die ondersoek in terme van die korrelasie tussen MuSSA vrae gebruik kan word om munisipale besluitneming te help verbeter.

Повний текст джерелаThe World Bank (1994) concluded that there is a close relationship between infrastructure and economic growth. This also reflects on the water sector because, despite water sector importance, water services infrastructure is probably one of the most difficult to finance, while its deficiency or absence instils a particular burden on society. According to Baietti and Raymond (2005), more than 1.1 billion people worldwide do not have access to safe drinking water, and approximately 2.4 billion are without adequate sanitation. Yet these estimates underestimate the gravity of the situation in relation to access gap and quality of services provided. Most consumers face situations where water services are intermittent and when available the water is not safe for consumption, while sanitation facilities are overloaded, unused or in despair. This research was conducted in the North West Province with municipalities that have the status of water services authorities. This included a combination of district and local municipalities. The North West Province has 11 water service authorities of which nine are local municipalities and two are district municipalities. The competing demands and needs for governments to provide infrastructure for other sectors such as roads and energy further aggravate the stance of finance unavailability for the water sector. The purpose of the study was to highlight the challenges that municipalities face in financing water services infrastructure. The result of the study will provide knowledge and innovative ideas that will allow South Africa‘s municipalities to address challenges of service delivery. At municipal level water services are provided through a variety of approaches, although most involve centralised systems with large supply, distribution and treatment facilities. The social benefits that water services provide are well known, particularly those that relate to public health including reduced morbidity and mortality from waterborne diseases. The challenge is that funding to meet these development objectives is either scarce or entirely unavailable. The Water Services Act 108 of (DWAF, 1997) requires water services authorities and water service providers to put significant efforts into cost recovery for sustainable provision of water services. This aspect has significant challenges which results from widespread poverty and a culture of non-payment from communities inherent as a remnant of protest against apartheid. The scope of the water sector is complex, owing to its diversity, interactions and synergies with other industrial, commercial and financial sectors, and its international nature. Under the current South African constitutional and legislative framework, municipalities will remain to be a major player in the development, financing and delivering of water services infrastructure for sustainable growth and development. Water Services Authorities (WSAs) have responsibilities including protection and management of water resources, provision of adequate and sustainable water services, operation and maintenance of water services infrastructure, monitoring and management of municipal water quality to regulatory requirements and reporting to the Department of Water Affairs (DWA) with regards to the aforementioned. Water service delivery failures at the municipal level are a widespread and fundamental problem in South Africa. At the same time, under the current decentralisation policies, the responsibility for delivering such services is increasingly being delegated to lower levels of government/municipalities that are often ill equipped for the challenge in terms of financial and human resources capacity. Cardone and Fonseca (2006) indicated public administration and financial management capacity at central and sub-sovereign levels of government as limited, and affecting the timely transfer of funding as well as the capacity of municipalities to absorb those funds. Various strategies are needed to enable municipalities to secure and finance their water services infrastructure. These include understanding what bankers are looking for, understanding where donors are going, greater involvement of the private sector, matching service levels to affordability, improving revenues and influencing the regulatory regime.

Повний текст джерелаENGLISH 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.

Повний текст джерелаENGLISH ABSTRACT: This study focuses on the water demand of selected residential properties with access to groundwater in serviced areas of the Cape Peninsula. This winter rainfall region is typified by hot and dry summer months, corresponding to peak garden water demand. Water restrictions in the area are relatively common and primarily target outdoor use. Groundwater serves as an alternative source of water to some consumers in the area, but little is known about the extent of such use and the impact thereof on potable water demand. A major part of the area is underlain by a primary, unconfined aquifer that has been reported to have high exploitation potential. Its unconsolidated sand and shallow water table provides ideal conditions for small scale groundwater abstraction. Several owners of properties situated above the aquifer unit have capitalised on this and utilise groundwater as an alternative to potable water, mostly for garden irrigation purposes. The main objective of this research was to investigate the average extent of the expected reduction in average annual municipal water demand due to private groundwater use at the selected properties in the study area. The methodology involved abstracting data from the City of Cape Town’s registration process for the private use of non-potable water. The data was recorded between 2000 and 2006 and was available only in hard copy format. The registration data was used to identify residential properties with access to private groundwater sources, based on the physical addresses recorded on the registration forms. The rate of groundwater abstraction was not recorded during the registration process, nor was any of the properties spatially referenced. The data set contained information for 4 487 properties, of which 3 764 could ultimately be used in the analysis. Data from a recent hydro-census in Hermanus (which was done by others prior to this study) was used to test the intended research method first. This trial investigation involved only 114 properties and was used to streamline the proposed methodology for application on the full-scale analysis of the City of Cape Town data. Each address was captured electronically, verified manually and filtered to extract only those representing residential properties for which groundwater use was registered. In order to identify the properties spatially, the addresses had to be converted to coordinates through a procedure called geocoding, so as to plot each spatially and obtain the attributes such as stand size, position and the unique Surveyor General’s code. This was necessary in order to link the addresses to the municipal treasury system and obtain their latest available water consumption records using a commercial software package that incorporates consumer information. Next the actual annual water consumption figures were compared with recently published water demand guidelines based on stand size as single explanatory variable. The selected residential stands were divided into pre-defined stand size categories. The average water consumption of all the stands in each size category was calculated and compared with the suggested water demand as per the guidelines used, based on the centre value of the size range of each category. The results of the comparative analysis confirm findings from two earlier studies where lower municipal water use was reported for residential properties with access to groundwater in a summer rainfall region. The results further showed that the mean average annual potable water demand of consumers in the study area with access to groundwater was on average 31.4% lower than those considered without such access in the same region. This represents an average reduction of 333 l/stand/day (about 10 kl/stand/month) in the potable water demand of the selected residential stands. This study therefore confirms that serviced residential stands with access to private groundwater sources in the Cape Peninsula have lower average metered water consumption from the municipal supply system.
AFRIKAANSE OPSOMMING: Hierdie studie fokus op die water anvraag van geselekteerde residensiële erwe met toegang tot grondwater in gedienste woongebiede van die Kaapse Skiereiland. Die gebied is ‘n winterreënvalstreek, met warm, droë somermaande wat saamval met piek water aanvraag vir tuinbou. Waterbeperkings in die area is relatief algemeen, veral op die buitegebruik van water. Grondwater dien as alternatiewe bron vir sommige verbruikers, maar kennis oor die omvang van sulke gebruik, sowel as die impak wat dit het op die aanvraag na drinkbare water is beperk. Die grootste deel van die gebied ter sprake is geleë bo ‘n onbegrensde hoof waterdraer, met berigte hoë ontginningspotensiaal. Die ongekonsolideerde sand en hoë watertafel is ideal vir kleinskaalse grondwateronttrekking. Heelwat van die eienaars van grond wat bo hierdie akwafeer geleë is het die situasie uitgebuit en gebruik grondwater as alternatief vir drinkwater, veral vir tuinbesproeiïng. Die hoofdoel van hierdie navorsing was om die gemiddelde omvang van die verwagte vermindering in gemiddelde jaarlikse munisipale wateraanvraag weens die privaat gebruik van grondwater by die geselekteerde erwe in die studiegebied te ondersoek. Die metodiek het die onttrekking van data uit die Stad Kaapstad se registrasieproses vir die privaat gebruik van nie-drinkbare water behels. Hierdie data, wat tussen 2000 en 2006 vasgelê is, was slegs in harde kopie formaat beskikbaar. Die registrasie data is gebruik om woonerwe te identifiseer met toegang tot privaat grondwater bronne, volgens die fisiese adres verskaf op die registrasie vorms. Die tempo van grondwater onttrekking was nie opgeneem gedurende die registrasie proses nie, so ook nie ruimtelike aanwysings na die ligging van die eiendomme nie. Die datastel het inligting bevat oor 4 487 eiendomme, waarvan 3 764 uiteindelik bruikbaar was in die analise. Data van ‘n onlangse hidro-sensus in Hermanus (wat deur ander gedoen is voor die aanvang van hierdie studie) is gebruik om die beoogde navorsingsmetodiek eers te toets. Die toetsondersoek het slegs 114 eiendomme behels, en is gebruik om die voorgestelde metodologie meer vaartbelyn te maak voor toepassing op die volskaalse analise van die Stad Kaapstad data. Elke adres is elektronies vasgevang, met die hand geverifiëer, en dan gefilter om slegs die residensiele eiendomme waarvoor grondwater gebruik geregistreer is, te behou. Om die ruimtelike verwysing van die eiendomme verder te kon indentifiseer, moes die adresse omskep word in koördinate om sodoende die erwe te kon posisioneer en die erfgrootte, posisie en die unieke Landmeter Generaal kode van elke erf te verkry. Dit was nodig sodat die adresse aan die munisipale stelsel gekoppel kon word om sodoende die jongste beskikbare waterverbruik rekords te verkry deur gebruik te maak van ‘n kommersiële sagteware pakket wat verbruikers-inligting inkorporeer. Hierna is die werklike jaarlikse waterverbruik syfers vergelyk met onlangs gepubliseerde wateraanvraag riglyne, gebaseer op erfgrootte as enkel verklarende veranderlike. Die geselekteerde woonerwe is toe in voorafgekose kategorië verdeel volgens erfgrootte. Die gemiddelde waterverbruik van al die erwe binne elke grootte-kategorie is bereken en vergelyk met die voorgestelde wateraanvraag volgens die riglyne, gebaseer op die middelpuntwaarde van die grootte strekking van elke kategorie. Die resultate van die vergelykende analise staaf die bevindinge van twee vroeër studies wat laer munisipale watervebruik rapporteer vir residensiële eiendomme met toegang tot grondwater in ‘n somerreënvalgebied. Die resultate wys ook dat die gemiddelde jaarlikse drinkbare water aanvraag van verbruikers in die studiegebied wie toegang het tot grondwater, gemiddeld 31.4% laer is as dit van verbruikers wie beskou word sonder sulke toegang in dieselfde streek. Dit verteenwoordig ‘n gemiddelde vermindering van 333 l/erf/dag (rondom 10 kl/erf/maand) in die aanvraag na drinkbare water van die geselekteerde woonerwe. Hierdie studie bevestig dus dat gedienste residensiële erwe met toegang tot privaat grondwater bronne in die Kaapse Skiereiland laer gemiddelde gemeette waterverbruik vanuit die munisipale toevoerstelsel het.

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

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. ..

Повний текст джерелаHuman 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.

Повний текст джерелаThe aim of the study was to examine the challenges of water supply management in Umdoni Local Municipality. Two methods were employed to collect data in the study. The first method involved one-on-one interviews with the participants. An interview guide was used to obtain data pertaining water supply services from a water services manager, a municipal manager and ten (10) ward councillors. The second method entailed analysis of documents within the municipality. In this study findings were based on issues such as prioritization of effective water supply for Umdoni Local Municipality, community consultation and participation, addressing capacity constrains in the Municipality such as human resources, water service infrastructure and skills development. The underlying causes of the water supply problems are based on the basic infrastructure, provision of water supply being very poor and dismal across the area. Water serves as a basic need to which everybody has the right to access, however, water supply is unfortunately disrupted by many factors. The findings in this study shows that poor water supply emanates from many factors such as management skills, technical challenges and illegal connections. This study recommends that Umdoni Local Municipality has additions of water plants, building of new reservoirs and upgrades of water pipes, especially in Amahlongwa area as it needs urgent attention.

Повний текст джерелаLesotho is a land locked country, entirely surrounded by the Republic of South Africa. Maseru is the capital of Lesotho and the country’s main centre for commerce and industry. The study area is located on the North-Eastern outskirts of the Maseru urban area. The catchment occupies an area of 44km2 with a length of about 13 km and channel slope of 0.4 km/km. The Maqalika Reservoir was built in 1983 to meet the water demands for Maseru city up to 1995, and its storage capacity was 3.7 Mm3. The storage is gradually decreasing as sediment, carried by the natural run-off accumulates in the reservoir. Moreover, water pumped into the reservoir from the Caledon River (which is heavily sedimented) adds its own contribution of silt. The reservoir is located in a very densely populated area, and is heavily polluted leading to high purification costs. The study was motivated by the fact that Welbedacht Dam was constructed in 1973 in the Caledon catchment but downstream of Maqalika. After 20 years, 85% of the volume of the dam was silted. The study was intended in finding whether the positioning of the Maqalika reservoir is acceptable and to find its remaining capacity as a water body supplying a fast growing city. Consideration was also given to the effect of land use practices on the water quality of the Maqalika reservoir, including the cost incurred during purification. The water quality data on physico- chemical was collected from the Water and Sewerage Authority and was analysed using excel spreadsheets. Results obtained were compared with WHO, SABS and National Standards of Lesotho. It was found that nitrates, phosphates and faecal coliforms levels were by far above minimum standards rendering water to be very contaminated and the source being leaking sewers, defeacation in dongas and leachate from Tsosane and Lower Thamae dumping site. Iron levels were also high with mean values beyond 0.3mg/l and the source being leachate from dumping sites, poor disposal of scraps and minerals from soil. Conductivity levels were high and the suspected source is waste solid disposal having a maximum of 442mS/m in March 2001. Hardness, temperature and alkalinity do not pose much danger to Maqalika water since recorded results were almost within limits. Turbidity levels were very high and the main source was found to be catchment sedimentation through run-off. For determination of the impact of sedimentation through pumping, hydrological data was obtained from the Department of Water Affair (DWA) and analysed using Excel spreadsheets to get sediment concentrations. A linear regression graph was plotted using discharge against sediment concentration that yielded y = 0.0007x – 0.0019. This was used in the Rooseboom mathematical equation for estimation of volume occupied by sediment from 1983 - 2002 and was found to be 6789 m3. For determination of the impact due to catchment run-off, a map method of estimating sedimentation from ungauged catchments developed by Rooseboom was used and a volume of 4.598 x 106 m3 was obtained showing that the main contributor of sedimentation in the reservoir is catchment run-off. The chemical costs employed during purification were also compared between WASA and Umgeni Water of Kwazulu- Natal and WASA was found to be expensive with 9 cents/kl while Umgeni spent only 5.24 cents/kl.
