Annual reports issued by the City of Tshwane (2015) for the financial years 2010 to 2014 show that the City of Tshwane has received qualified audit reports from the South African Auditor General (2015). The two key causes of underperformance were lack of adherence to norms and standards that are applicable to municipal service delivery and lack of adherence to the fundamental principles of good corporate governance (King, 2009). A study was conducted in the City of Tshwane, South Africa in order to assess and evaluate the degree of adherence to good corporate governance principles stipulated by Mervin King (King, 2009) in the form of the King III report. Data was collected from a stratified random sample of size 1, 012 residents of the City of Tshwane. Stratification was done by geographical zone. Data was collected from respondents by using a structured, pre-tested and validated questionnaire of study consisting of 22 indicators of service quality. The study found that 84.37% of respondents who took part in the study were satisfied with the overall quality of municipal services that were provided to them by the City of Tshwane. Only 15.63% of respondents were not satisfied with the overall quality of services provided to them. The study showed that most of the respondents had a positive perception on the quality of routine municipal services such as water and lights and waste removal by employees of the City of Tshwane. The study showed that the degree of satisfaction of residents, ratepayers and stakeholders with the quality of municipal services that were provided to them was significantly influenced by the degree of motivation of employees of the City of Tshwane at work, the ability of employees of the City of Tshwane to treat all customers with respect, the ability of employees of the City of Tshwane to provide adequate answers promptly to queries raised by customers, and the degree to which employees of the City of Tshwane were skilled on technical issues, in a decreasing order of strength.

The purpose of the study was to identify and quantify differential factors that undermine the quality of municipal services that are provided to residents of the City of Tshwane. Data was collected from a stratified random sample of size 1, 012 residents of the City of Tshwane. Stratification was done by geographical zone. Data was collected from respondents by using a structured, pre-tested and validated questionnaire of study consisting of 22 indicators of service quality. The questionnaire of study consisted of 5 dimensions of expectation and perception (reliability, assurance, tangibles, empathy and responsiveness). Each of the 1, 012 respondents in the study had to provide answers to 22 questions related to expectations plus 22 questions related to perceptions. As such, each of the 1, 012 respondents had to provide answers to 44 questions (22 questions on expectation + 22 questions on perception). Measurements of expectations and perceptions were done by using a 5-point ordinal scale. Face validity was used for ensuring validity. The Cronbach Alpha test was used for ensuring reliability and internal consistency. The expected and perceived quality of emergency services provided to the general public by employees of the City of Tshwane was analyzed by using SERVQUAL analysis. This was done by estimating gap scores (the average difference between expected and perceived scores). The study found that 84.37% of respondents who took part in the study were satisfied with the overall quality of municipal services that were provided to them by the City of Tshwane. Only 15.63% of respondents were not satisfied with the overall quality of services provided to them. The study showed that most of the respondents had a positive perception on the quality of routine municipal services such as water and lights and waste removal by employees of the City of Tshwane. The study found that as many as 87.13% of respondents had a positive perception about the degree of commitment shown to them by employees of the City of Tshwane. Based on results obtained from SERVQUAL analysis, 20 of the 22 gap scores were found to be significant at the 5% level of significance. There were only 2 items (out of a total of 22 items) that did not produce significant gap scores. These 2 items were items 2 and 3 of the dimension on responsiveness. Item 2 of the dimension on responsiveness was an assessment on the degree of suitability of the equipment used by municipal employees for carrying out routine services. Item 3 of the dimension on responsiveness was an assessment on the degree of physical fitness of employees of the City of Tshwane for carrying out routine municipal services effectively. With the expectation of the 2 gap scores corresponding to these 2 items, all other gap scores (20 out of 22) were statistically significant at the 5% level of significance. Based on results obtained from factor analysis, the perception and expectation of respondents on the quality of municipal services that were provided to them were significantly influenced by 4 key predictors of perception. These 4 predictor variables were the degree of motivation of employees of the City of Tshwane at work, the ability of employees of the City of Tshwane to treat all customers with respect, the ability of employees of the City of Tshwane to provide adequate answers promptly to queries raised by customers, and the degree to which employees of the City of Tshwane were skilled on technical issues, in a decreasing order of strength. Similar results were obtained from logit analysis. The results showed that the perception and expectation of respondents were influenced by similar variables of study.

Testo completoAbstract (sommario):
Households in many cities worldwide consume substantial amounts of water, but increasing aridity will result in serious water supply challenges in the future. In South Africa, droughts are now a common phenomenon, with severe implications on water supply for urban households. Developing interventions to minimise the impacts of drought requires understanding of users’ perceptions of water scarcity, water use practices, and participation in water conservation practices. Using household surveys across different income groups (low, medium, and high) in Makhanda, South Africa, this study investigates households’ perceptions of water scarcity, water use, and conservation practices as a basis for designing pathways for sustainable water use practices. Results indicate that a substantial proportion of households were aware of water scarcity and attributed it to poor municipal planning rather than drought and wasteful use practices. Households reported good water use behaviour, but wasteful practices (e.g., regular flushing of toilets) were evident. Gender, age, education, and environmental awareness influenced water use practices, but the relationships were generally weak. Households participated in water conservation measures but felt the local municipal authority lagged in addressing water supply challenges. The implications of the study are discussed.

Abstract Cape Town recently endured a record-breaking drought which nearly ended in disaster for the city's water supply. Municipal authorities introduced several measures to curb water demand using both monetary and other incentives, but little is known about how effective these measures were at encouraging people to save water. Previous literature shows no consensus as to which types of measures are most effective for managing residential water demand. Using information obtained through semi-structured, in-depth interviews with 20 individuals living in houses where they paid their water bills, this study provides insights on how respondents interpreted and responded to these mechanisms. Results show that price mechanisms were considered to be ineffective and did not encourage people to save water in their households. Non-price mechanisms were seen as having more impact on respondents, encouraging water conservation behaviour; especially when it comes to household indoor water use activities related to hygiene. While previous studies primarily provide quantitative data to measure the effectiveness of water demand management strategies, this paper adds a qualitative understanding of how and why households' water use practices change in response to these measures.

Testo completoAbstract (sommario):
This paper shows how water poverty mapping using census data and the Water Poverty Index can be used to identify effectively the most water-poor households in a region for the targeting of water supply development policies and projects. The main findings come from a case study conducted in the Estcourt municipal district in South Africa where simple water poverty maps were developed using readily available data sources at three different scales: enumerator area, place names and sub-catchment. The efficiency of targeting the most water-poor households using the different scales of water poverty maps were measured by comparing both the inclusion and exclusion rates of targeting and comparing them with other similar targeting studies. The distribution of water poverty within a community was also compared with the results of a detailed household questionnaire conducted as part of the broader development of the water poverty index (WPI). The main conclusion from the study is that water poverty mapping is a strong visual extension of the WPI that has great potential for providing a practical way for water management authorities and decision makers to identify and target the most water poor households and monitoring the impacts and tangible benefits of water supply development policies.

Testo completoAbstract (sommario):
In 2001 South Africa introduced a social policy to provide all citizens, but particularly the poor, with a monthly supply of limited volumes of free water. Although criticised by international agencies at the time, lifeline tariffs to the poor are now promoted as a strategy to meet the Millennium Development Goals. Much of free basic water's contemporary allure lies in its ostensible artifice in offering water security to poor citizens whilst simultaneously strengthening the municipal cost-recovery regime. Past attempts at unravelling what has become something of a social policy allegory were hindered by the absence of a state voice in this intriguing narrative. A legal challenge launched by poor Soweto, Johannesburg citizens has enabled the public to have access to state affidavits. These primary data, together with improved positioning of free water literature within a broader scope of municipal water systems (rights, volumes and tariff structures), socio-political paradigms and a more rigorous interrogation of previously uncontested international standards and ideological ‘neutral’ discourses provide a more comprehensive chronicle of the complex free water narratives. As such, the offering of free water, far from being a benign concession, was used to contain very poor households to limited volumes of water beneath what they required whilst ensuring that the majority of still poor households, who consumed beyond the free volumes, paid the full cost of the water service.

The Draft Second National Water Resources Strategy of South Africa, which has been published for comment, has identified the implementation of water use efficiency, conservation and water demand management as a core strategy to ensure sufficient water to meet South Africa's needs going into the future. This, ‘non-negotiable performance area’, it says, must be implemented immediately in all water use sectors, specifically municipalities. ‘In view of water scarcity, it is essential that such water losses must be curtailed, especially in terms of the need to provide for the growing water demands of new socioeconomic development’, the strategy points out. While South Africa's non-revenue water levels compare well internationally, as a water scarce country it needs to do all it can to prevent the unnecessary loss of water. This is one of the main recommendations of a recent study into the state of non-revenue water in South Africa commissioned by the Water Research Commission (WRC). To improve the current situation, the water sector must have a clear indication of the current status of non-revenue water in South African municipalities, more specifically what the actual water losses are and how they are split between physical leakage (real losses) and commercial losses (apparent losses). It is for this reason that the WRC, in collaboration with the Department of Water Affairs, launched the latest investigation into the state of non-revenue water in South Africa, which has now been published. In the most comprehensive and detailed study of its kind, to date, data were gathered from 132 municipalities throughout South Africa representing over 75% of the total volume of municipal water supply. The study follows on from similar WRC assessments undertaken in 2001, 2005 and 2007. This is the first time the country has a single, representative estimate of non-revenue water as opposed to various estimates in previous years. The paper shares in more detail findings from this study which have highlighted on average 38% non-revenue water and provide a deeper insight into the problems and challenges faced in tackling water losses in South Africa.

Testo completoAbstract (sommario):
In the study area of Hermanus, South Africa, the Gateway Wellfield is used to augment municipal water supply. Due to the coastal location, the impact of saline intrusion needs to be considered. The confined Peninsula Aquifer comprises a complex fault system in a fractured rock environment. Analytical equations do not indicate any negative impact of saline intrusion. The impact of different parameters on the interaction between fresh and sea water was tested in a 2D sensitivity analysis. The hydraulic gradient and dispersivity were identified as crucial parameters. In addition, the impact of discrete fractures within a porous medium was tested. Fracture apertures in the likely range of the case study (b < 1 mm) showed a negligible effect. The geology of the Peninsula Aquifer was modelled as an Equivalent Porous Medium (EPM) whereby highly fractured zones around the faults were assigned high hydraulic conductivity. A maximum increase in salinity of 30 mg/l was predicted for the first 20 years of groundwater abstraction. An impact of vertical fractures with b > 1 mm was detected that is hardly predictable. In order to prove the gained conclusions and completely eliminate a harmful impact, further investigations are recommended.

Testo completoAbstract (sommario):
Mopani District Municipality in the northeast of South Africa is largely semi-arid and frequently affected by meteorological droughts. The recent 2015/16 event had devastating impacts on water levels, crop yields, livestock herds and rural livelihoods. We investigated the nature of the drought hazard; its impacts, including vulnerability of rural communities in Mopani District and adaptation strategies they have employed to cope with drought. A mixed methods approach with both quantitative and qualitative datasets was used. The district was divided into two distinct climatic areas: the drier eastern lowveld and the wetter western bushveld. Questionnaires were administered among community members whilst key informant interviews were conducted among relevant government and municipal officials. Climate data was used to characterize historical drought using a Standardized Precipitation and Evapotranspiration Index whilst vegetation anomaly maps were used to demonstrate impacts. Spatially distinct patterns of drought conditions were evident with harsh and dry conditions towards the east. It was found that nearly half the time there is some form of drought or another in the district mostly linked to the remote El Nino phenomenon. In several areas, rain-fed agriculture is no longer tenable, with a direct impact on rural livelihoods. A Household Vulnerability Index determined variable levels of vulnerability such that different strategies are employed to adapt to drought some of which cause environmental problems. Local government intervention strategies include supply of seeds and fertilisers, providing cheap fodder and supplying water using trucks. The findings of this study contribute to disaster risk reduction efforts in a region that is highly vulnerable to current and future climate-risks.

Diarrhea is a common cause of child-related hospitalization and mortality among children under the age of five in South Africa. This study was conducted to assess the knowledge and practices of caregivers regarding prevention and management of diarrhea among children under the age of five in the Thulamela Municipality of South Africa. A quantitative approach using a descriptive cross-sectional survey was used. A questionnaire was adopted to collect data from caregivers at thirty primary health-care facilities using convenient sampling. Statistical Package for Social Sciences (SPSS) version 24.0 was used to analyze data. Most of the respondents have fair knowledge about diarrhea, oral rehydration therapy/salt sugar solution and its usage during diarrheal episodes. However, most of them (81.7%) do not use the salt sugar solution when their children have diarrhea. Almost all the respondents practice a hand washing hygiene for themselves and their children; 97.2% do not reheat cooked food before feeding their children; 95.5% do not drink untreated water as their source of drinking water is the municipal supply. The practices of these respondents do not reflect their knowledge in terms of the use of oral rehydration solution/salt and sugar solution. Further efforts should be made to educate caregivers on the mode of transmission of diarrheal pathogens.

Testo completoAbstract (sommario):
Background Population growth at all scales and rapid rates of urbanization, particularly in the global South, are placing increasing pressure on ecosystems and their ability to provide services essential for human well-being. The spatial consideration of threats to ecosystem services related to changes in land use is necessary in order to avoid undue impacts on society due to the loss or reduced supply of ecosystem services. This study assesses the potential threats of land use change from strategic and local development proposals to ecosystem services in the city of Durban. Methods We analysed the spatial relationship between five categories of ecosystem service hotspots (carbon storage, water yield, sediment retention, nutrient retention and flood attenuation) and urban land use change related to selected strategic planning proposals, development proposals and sand-mining applications in Durban, South Africa (eThekwini Municipality) with a view to determining the consequences for progress towards a more sustainable development path in the city. We identified the potential levels of threat related to habitat destruction or transformation for the five categories of ecosystem services and a subset of 13 ecosystem service hotspots, using GIS spatial analysis tools. Results The results show that on average, should Durban’s strategic development plans be realised, approximately 42% loss of ecosystem service hotspots is expected in the two municipal town-planning regions assessed. With respect to development applications between 2009 and 2012, approximately 36% of all environmental impact assessments and 84% of sand mining applications occurred within ecosystem service hotspots within Durban. Discussion The findings highlight the tension between short-term development pressures and longer-term sustainability goals and confirm that current planning and development proposals pose a threat to ecosystems and their ability to deliver services that support human well-being in Durban. We suggest practical solutions to include ecosystem services into local government decision-making.

Testo completoAbstract (sommario):
A customised Water-related Quantitative Microbial Risk Assessment (WRQMRA) process was used to determine risk of infection to water ingested by users in the south-eastern Free State, South Africa. The WRQMRA consisted of an observed-adverse-effect-level approach (OAELA) and a quantitative microbial risk assessment (QMRA). The OAELA was based on the occurrence of E. coli in the study waters to determine the possible risk of infection and the QMRA probable risk of infection by salmonellae. The WRQMRA was applied to recreational surface resource waters as well as waters from an unprotected spring and waters from the treated municipal supply that were stored in containers for domestic purposes. E. coli numbers were measured against expected infection levels expressed in water quality guidelines, while Salmonella counts were calculated to give the probable infection risk (Pi). Ingestion was based on intake volumes compiled for the various water uses. E. coli occurred in numbers <106 in the surface waters, while the untreated spring and treated supply water contained E. coli of <102 and <101 respectively. Salmonella occurred in numbers of <103 in recreational waters, and <10-1 in water used for domestic purposes. A single exposure to the mean (as well as 95th percentile) risk was calculated using a β-Poisson dose-response model at ingestion volumes of 100 mL (for full-contact recreation) and 1,318 mL (for domestic water use). Both the OAELA and the QMRA approaches indicated a risk of infection to recreational and domestic water users, even for a single exposure event, with the OAELA either over- or under-estimating the risk of infection for singular exposure events. This indicated that this method, used on its own, could not reliably predict a realistic risk of infection. It is recommended that the full WRQMRA process be used, and further developed to address several uncertainties that became evident during this study.

Personal hygiene and access to potable water, which is safe for human consumption, are critical to containing the COVID19 pandemic. Here monitoring results are reported for microbial quality of water samples from the municipal supply in Makana Local Municipality in the Eastern Cape Province, South Africa. Access of the human population to sufficient volumes of potable water of required (microbial) quality has been a problem in this local municipality. Samples were taken just before and during 30 days of the strictest phase of the nation-wide lockdown, related to COVID19 in South Africa. Aim of this short communication was to perform the water quality testing with limited to no access to laboratory facilities and using the principles of citizen science. The H2S test kit was used as the basis for the microbial testing, while a cell phone app was used for the temperature monitoring. Five H2S test kit were used per sampling at the author’s house and the kits was developed for the microbial water quality assessment in isolated settings such as those for the lockdown. During the study, the ambient temperature ranged from 17 to 29 °C, with decreases below 18 °C occurring on three out of 12 sampling occasions. Thus the results of the H2S test kit might have been slightly influenced by the fluctuations of the ambient temperature. On 8 sampling occasions between 1 and 4 H2S test kits were positive for faecal contamination. Three samples or 25 % were free of faecal contamination. One sample had all five H2S test kits were positive for faecal contamination. Results of statistical testing indicated that potable water in Makana Local Municipality was probably microbially contaminated at the author’s household on an intermittent basis. Ongoing monitoring of microbial drinking water quality is necessary and continuing at the sampled location.

Testo completoAbstract (sommario):
This article looks at the town engineers in South Africa prior to Union in 1910. It briefly examines the growth in the number of municipalities and town engineers in the country in this period and investigates the background and training of these engineers; why municipalities decided to appoint an engineer; and what kind of appointment processes were followed. Finally the relations between engineers and town councils and the prevailing circumstances at the end of the engineers’ tenures is studied. The article also presents ten specific cases which have reference to the development of water supply. It emerges that most early town engineers received training via apprenticeship for the positions they held, and that there was added pressure from elected councillors in municipalities who were prone to monitor assiduously how officials were spending public money. It is also clear that engineers who did not have earlier municipal experience were bound to have problems in their interaction with town councillors.Keywords: Municipal history, civil engineering, water supply, sanitation, Cape Colony, Natal, Orange Free State, TransvaalDisciplines: History, Engineering, Public Management

All South Africans, especially, those involved with the development and management of its water resources should be aware that South Africa is generally an arid to semi-arid region, with an average rainfall of approximately 500 mm per annum, compared to a world average of 860mm. Consequently, potable water is a very scarce resource, and is often the biggest prohibiting factor for development of, for example, new residential areas in a town or city.Hence a public service rendering municipality like the Tlokwe (Potchefstroom) City Council will have to, in its quest to manage its potable water supply more effectively, efficiently and economically, take cognisance of aspects such as:· The origin of its potable water;· The nature and extent of the storage and treatment of the potable water;· The manner in which the potable water is distributed to the users and consumers;and· The manner in which the wastewater is collected, treated and managed.The authors of this article are of the opinion that the aforementioned can only be taken care of effectively by incorporating a physical environmental management perspective in its municipal governance.

Testo completoAbstract (sommario):
SA has set bold targets to ensure universal access to water and sanitation by 2014. One consequence of South Africa's comparative wealth is that government has substantial fiscal resources to fund rapid infrastructure development and service upgrading and subsidise a portion of the recurrent costs of water and sanitation services for low income households. More than 70% of the population now has at least a VIP toilet, and about 56% have sewered flush toilets. Government's commitment to improving sanitation services does not yet align with the municipal capacity to run sewered sanitation with centralised wastewater treatment as the default in all urban settlements. Decaying networks, sewer spills and rising levels of wastewater treatment failure are polluting South Africa's water systems and, in time, could compromise national water security in a context of growing scarcity. South Africa urgently needs to find lower cost, less skills-intensive ways of treating wastewater that have a reduced risk of failure and which meet people's need for robust, sustainable services. DEWATS approaches have significant merit. Implementation of DEWATS approaches in South Africa must take account of three main challenges:▪ The willingness of South African municipalities to consider alternatives to conventional sewering and wastewater treatment▪ The nutrient load of the final treated effluent, given the importance of safe-guarding river water quality in a context of growing water scarcity▪ Partnering and co-management dynamics in a context of state-centric supply-side service provision The paper reviews each in the context of a leading innovator in sanitation improvement in South Africa, eThekwini Metro Municipality. In 2010, the Metro will test the technical limits of DEWATS treatment efficacy at a purpose-built research site. The results will inform the utility's decision about whether to proceed with DEWATS from a technical perspective, and if so, how.

Testo completoAbstract (sommario):
This paper describes the technological development of wells and toilets and the cultural practices related to them in two countries, South Africa and Finland, from the Middle Ages to modern times. Wells and toilets have always been linked to the well-being of humans and they still are the most common technical systems in the service of mankind. They are simple to build, but if they are constructed improperly or stop functioning properly, they may endanger the health of both humans and the environment. The solutions used for getting clean water or for disposal of excrement have always been a matter of life and death for human settlements. Located on opposite sides of the world, the climate and natural resources of South Africa and Finland are very different. However, surprisingly similar solutions, for example wind turbines to pump water, have been used in rural areas. Furthermore, urbanization and industrialization occurred in both countries at approximately the same time in the 19th century, which caused increasing environmental problems in Finnish and South African urban areas. The transition to modern water supply and waste disposal systems was a very demanding process for municipal administrations in both countries.

This paper is an endeavour to investigate the implementation of housing programmes in relation to the access which they have to social amenities in South Africa. It has been based on a broader study of the implementation of housing programmes in the Amathole District of the Eastern Cape province of South Africa. The research sample comprised 276 participants, 250 of whom were residents of houses which had been provided by the housing programmes, 4 were municipal housing officials of the 4 selected municipalities, while the remaining 22 comprised provincial housing officials, representatives of political parties, municipal managers, councillors and social workers. The findings revealed that the toilets in the houses were generally in a very poor condition and that, in some cases, the houses had no toilets. Most of the houses were also adversely affected by a lack of basic essential amenities, such as the lack of a supply of clean water, a lack of electricity and the lack of a sewage disposal system. In order to ensure that the previously marginalised people of South Africa receive the social justice which had been denied to them for decades by the apartheid regime, providing houses with proper access to basic essential social amenities should be prioritised within a social developmental approach. In accordance with the democratic principles which are enshrined in the Constitution of South Africa, a bottom-up approach should be adopted for the implementation of appropriate interventions to ensure that the actual needs of the people are met.

Carletonville is a gold-mining town in western Gauteng province, South Africa, and is located in the Merafong City Local Municipality’s geographical area of responsibility. It is one of the richest gold-producing areas in the world but unfortunately the current state of the town’s infrastructure is in shambles and the environment is in a pitiful state because of human activities that have caused massive physical changes. Geohydrological aspects such as complex geology and the compartmentalisation of the groundwater into seven areas separated by syenite dykes, of which five have been dewatered to facilitate the gold-mining, have made it the research area of choice. Unfortunately, this led to the formation of hundreds of new sinkholes between the towns of Westonaria and Carletonville and eventually the evacuation of the old town of Bank, abandoning the area and declaring it unsuitable for human settlements. To try and identify possible reasons for this unfortunate state of the human-induced environmental change all along the Wonderfontein Spruit draining the area, the author using a comprehensive literature review, study of geological maps and databases as well as through data collection and semi-structured interviews with selected role-players and stakeholders identified basic essential geographical, geohydrological, organisational and municipal management aspects of significance for consideration. These steps were all a part of an attempt to improve the nature and extent of basic water-, sanitation-, human settlements- and environmental management in the Westonaria, Carletonville and Khutsong areas.

"Urbanisation and its effect on risk factors associated with childhood diarrhoea in Mbour, Senegal: A visualisation". Geospatial Health, 27 novembre 2017. http://dx.doi.org/10.4081/gh.2017.632.
Testo completoAbstract (sommario):
Rapid urbanisation, particularly in secondary cities in Africa, brings along specific challenges for global health, including the prevention and control of infectious diseases such as diarrhoea. Our purpose was to visualise urbanisation trends and its effect on risk factors associated with childhood diarrhoea, e.g. water supply, sanitation, wastewater and solid waste management in Mbour, a secondary city in south-western Senegal. Our visualisation is facilitated by epidemiological and geographical surveys carried out in 2016. A deeper spatial and visual understanding of the urbanisation trends and the disparities of diarrhoea-associated risk factors might lead to the implementation of suitable health interventions and preventive measures. Our visualisation is aimed to serve as a basis for discussion and as a decision support tool for policymakers, municipal officials and local communities to prioritise interventions related to water, sanitation and waste management with a view to reduce the environmental and health risks in the rapidly growing city of Mbour, which is set as an example for other similar secondary cities across low- and middle-income countries in Africa.

Local government in South Africa (SA) has come a long way from the period when there were over 1200 racially segregated municipalities. From more than 800 municipalities after 1996, they have been merged to currently 284 municipalities which now cover every ‘millimetre’ of the country, and are focused on growing local economies and maintaining the provision of a lot more diverse and complex basic municipal services to all their citizens and especially to geographical areas and citizens that were previously neglected. This transformed local government environment has brought about many changes in the nature and extent of basic public services delivered at the grass- roots level of this developing country with its limited resources and unlimited needs – especially in the areas of potable water supply and sanitation services.This article will firstly highlight the changed environmental context of public service delivery in the local government sphere of the country before the transformation in relevant legislation will be reported on. Subsequently the nature and extent of current realities of local governance, dynamics and challenges regarding the diverse and complex public services by a typical Category B Local municipality will be identified in the real SA out there. The use of the Politics – Administration System Model by Easton for environmental management analysis will also be illustrated. Lastly, for easy classification of typical characteristics and challenging issues in the dynamic municipal government sphere of SA, the SWOT-analysis format will be used.
