The start of the 21th century is notable for the apparent lack of safe drinking water and sanitation. Over one billion people in all parts of the world lack access to clean water. Most live in developing countries, such as Africa. Unsafe water and poor sanitation have been primary causal factors in the vast majority of water-borne diseases, especially diarrheal ones. The South African Constitution (Act 108 of 1996, Chapter 2, Section 24) states: “Everyone has the right: (a) To an environment that is not harmful to their health and their wellbeing; and (b) To have the environment protected, for the benefit of present and future generations, through reasonable legislative and other measures that prevent pollution and ecological degradation; promote conservation; ecologically sustainable development, and the use of natural resources, while promoting justifiable economic and social development.” Secondly, section 27 states that: “Everyone has the right to have access to: (a) Health-care services, including reproductive health care; (b) Sufficient food and water; and (c) Social security, including, if they are unable to support themselves and their dependants, appropriate social assistance.” These factors have prompted this research within the Ugu District Municipality on the perceptions of inadequate rural water service delivery. This study reveals information on those areas in the Ugu District Municipality, which do not have access to clean water, and on the health hazards that might lead to death if residents’ lack of access to clean water persists. The Ugu District Municipality, is situated in KwaZulu-Natal Province, and covers a surface area of 5866 km2. There are six local municipalities in this district. These are: Ezinqoleni, Umzumbe, Umziwabantu, Hibiscus Coast, Umdoni and Vulamehlo. The node is 77% rural and 23% urban, and the total population for this area is 704027 (Ugu District Municipality IDP 2nd 2011/2012:19). / M.

A Douala au Cameroun, ville de près de 4 millions d'habitants, à peine 40 % de la population a accès au service officiel de distribution d'eau. Les autorités publiques locales et les opérateurs de service sont ainsi confrontés aux défis liés aux dynamiques démographique et spatiale, se traduisant par une demande importante de service. Dans un contexte de réformes (de privatisation, bonne gouvernance, participation), l'enjeu est de concilier efficacité économique et équité socio-spatiale, par le rattrapage du service au profit des quartiers défavorisés des périphéries en développement, à travers le réseau conventionnel. Les inégalités socio-spatiales d'accès à l'eau observées résultent du projet de ville ségréguée, mis en œuvre dès la période coloniale, puis perpétué par l'Etat néo-patrimonialisé au cours de ses opérations de lotissement. Au cours de la décennie 1980, les insuffisances du service conduisent les bailleurs de fonds internationaux à recommander à l'Etat des réforn1es institutionnelles et gestionnaires. A Douala, le retrait de l'Etat du service public ne s'est pas accompagné par une substitution du tout-privé au tout-Etat. Les pratiques informelles courantes au sein de l'appareil politico-administratif, et les arrangements avec les opérateurs privés, analysés de l'échelle centrale à celle locale, permettent de rendre compte des mécanismes de redéploiement de l'action publique, et plus largement du fonctionnement de l'Etat. A l'échelle de la ville, des coalitions d'acteurs publics et privés, mais aussi d'acteurs chevauchant entre la sphère politique et la sphère économique, les Big-men, politiciens entrepreneurs, organisent le marché de l'eau. Au sein des territoires communaux, la superposition des pouvoirs et l'asymétrie des ressources entre les différents intervenants engendrent des conflits de gouvernance, avec des conséquences pour la cohérence urbaine et la généralisation de l'accès des populations à l'eau. / In 2010, the population of Douala was estimated at more than 3 million in habitants. As a result of a combined effect of rural urban migration and a high natural rate of population increase, the average population growth rate was 6.3% per year. Population growth and the expansion of the city have led to an increase in the demand for water by the urban population. Paradoxically, from the second half of the 1980s, (in a context of the economic crisis), the State has significantly cut down on construction and development in the city suburbs, most particularly with regard to investment in water services (CUD, 2011 ). The State faces many challenges such as ; (i) how to reduce the socioeconomic disparities, in an urban context where the majority of the people are poor and Jack access to basic public services (ii) how to ensure social equity in the distribution of drinking water and finally, (iii) how to balance these two fundamental aspects and ensure economic growth. The Urban authorities cannot ensure the continuity of the basic services. As a result, access to drinking water by the urban people represents a key public policy challenge. As a consequence, the past decade, has seen the emergence of largely informal private water providers, in the periphery of the city in a bid to enable access to water to an increasingly larger urban population. The study focuses on the private alternatives of water production and distribution developed by small local operators and the consequences of this on urban area production.

The present article aims to review the development of universal access to potable water in Peru, for this, firstly it analyses the regulations applicable to potable water and sanitation, the main actors of the activity and universal access policy. Subsequently, it explains how the access of all users to potable water in urban and rural areas, respectively is planned. / En el presente artículo se da cuenta del desarrollo del acceso universal al agua potable en el Perú. Para conseguir ello, previamente, se analiza el régimen jurídico del agua potable y saneamiento, los principales actores de la actividad y la política de acceso universal. Esto permite, posteriormente, explicar cómo es que se ha previsto conseguir el acceso de todos los usuarios al agua potable en los sectores urbanos y rurales, respectivamente.

Från om med 1 januari 2024 ska alla kommuner ha en vattentjänstplan. En vattentjänstplan ska innehålla varje kommuns långsiktiga plan för att tillgodose allmänna vattentjänster i framtiden samt åtgärder som behöver vidtas vid skyfall för att skydda VA-anläggningar. Lagändringen infördes 1 januari 2023 vilket har gett kommuner en snäv tidsplan att ta fram denna plan. Arbetet har undersökt vad vattentjänstplanen i Västerås kommun behöver innehålla för att uppfylla kravet om åtgärder vid skyfall, identifiera punkter i spill- och dagvattennätet som potentiellt är sårbara för skyfall och ge förslag på skyfallsåtgärder. För att uppfylla syftet har en risk- och sårbarhetsanalys utförts för att identifiera punkter i spill- och dagvattennätet som är sårbara för skyfall. Analysen inkluderade en workshop med nyckelpersoner på Mälarenergi Vatten AB och en riskmatris som användes som bedömningsunderlag. Från riskmatrisen identifierades punkter som var potentiellt sårbara för skyfall och en lågpunktskartering utfördes i SCALGO Live på utvalda punkter. De regnhändelser som utfördes i karteringen var 10-, 20- och 100-årsregn. Lågpunktskarteringen jämfördes även med en skyfallskartering med markavrinning och ledningsnät, vilket är en kartering av hög detaljeringsgrad, för att undersöka ifall lågpunktskartering kan vara lämpligt underlag till en vattentjänstplan. Resultatet av risk- och sårbarhetsanalysen var att sju punkter, som gavs som förslag under workshopen, hade höga riskvärden och var potentiellt sårbara för skyfall. Tre av sju punkter valdes till vidare analys: Branthovda, Skiljebo och Önsta-Gryta, alla belägna i Västerås tätort. Samtliga av dessa tre punkter var i dagvattennätet. Lågpunktskarteringen i SCALGO Live som utfördes över dessa tre punkter visade stora översvämningar vid ett 100-årsregn. Skyfallsåtgärder som föreslogs för platserna var magasinerings ytor och skyfallsled. Vid jämförelse av lågpunktskartering och skyfallskartering med markavrinning och ledningsnät visade skyfallskarteringen en mindre översvämning för Branthovda och Skiljebo. I Önsta-Gryta var skillnaden mellan karteringarna minimal. Detta var då skyfallskarteringens resultat visar på att dagvattenledningarna i området var överbelastade redan vid ett 10-årsregn, vilket liknade villkoret i lågpunktskarteringen att dagvattenledningarna antas vara fulla. Med detta kan endast en lågpunktskartering visa ett områdes potential till att var sårbara för skyfall, men säger inget om hur spill- eller dagvattennätet påverkas. Dock kan en lågpunktskartering hjälpa till att identifiera områden i tätorter som skulle kunna vara sårbara för översvämningar. / As of January 1st, 2024, all municipalities must have a water service plan. A water service plan must contain each municipality's long-term plan to provide public water services in the future and solutions that need to be taken in the event of a cloudburst to protect water and sewage facilities. The change in law was introduced on January 1st, 2023, which has given municipalities a tight timetable to develop this plan. The study has investigated what the water service plan in Västerås municipality needs to contain in order to fulfill the requirement for solutions in the event of cloudbursts, identify points in the waste and stormwater network that are potentially vulnerable to cloudbursts, and provide suggestions for torrential rain measures. In order to fulfill the purpose, a risk and vulnerability analysis has been carried out to identify points in the waste and stormwater network that are potentially vulnerable to cloudbursts. The analysis included a workshop, with key individuals at Mälarenergi Vatten AB, and a risk matrix that was used as an assessment basis. From the risk matrix, points that were potentially vulnerable to cloudbursts were identified and a low-point mapping was performed in SCALGO Live at the selected points. The rain events performed in the mapping were 10-, 20- and 100-year rainfalls. The low-point mapping was compared with a cloudburst mapping with land runoff and conduit network, which is a mapping with a high degree of detail, to investigate whether low-point mapping can be a suitable basis for a water service plan. The result of the risk and vulnerability analysis was that seven points, which were given as suggestions during the workshop, had high-risk values and were potentially vulnerable to cloudbursts. Three out of the seven points were selected for further analysis: Branthovda, Skiljebo, and Önsta-Gryta, all of them located in Västerås city. All of these sensitive points were in the stormwater network. The low-point mapping in SCALGO Live performed over these three points showed major flooding during a 100-year rainfall event. The proposed cloudburst solutions for the sites were storage areas and cloudburst roads. When comparing low-point mapping and cloudburst mapping with ground runoff and conduit networks, the cloudburst mapping showed a minor flood for Branthovda and Skiljebo. In Önsta-Gryta, the difference between the mappings was minimal. This was due to the results of the cloudburst mapping showing that the stormwater pipes in the area were overloaded even with a 10-year rain, which was similar to the condition in the low-point mapping that the stormwater pipes are assumed to be filled. With this, only a low point mapping can show an area's potential for being vulnerable to cloudbursts but does not say anything about how the waste or stormwater network is affected. However, low point mapping can help identify areas in built-up areas that could be vulnerable to flooding.

LLM / Department of Public Law / Historically, there were enormous differences and inequalities with regard to service delivery in South Africa. Traceable to the apartheid period, these inequalities included, inter alia, supply of inadequate and safe drinking water for black communities in particular those at rural areas. Yet, water is an essential necessity for human beings, regardless of race, disability and social status. As a legislative measure to redress the injustices of the apartheid regime, the right to have access to sufficient water is entrenched in Section 27(1) (b) of the South African Constitution of 1996. Also, several legal instruments such as the National Water Act of 1998 and the Water Service Act of 1997 were enacted to uphold the human right to water. The Constitution bestowed the responsibility of water supply and management to the national, provincial and the local government. Despite its inadequacy, the South African government is addressing the water needs of the most impoverished communities by guaranteeing each household a free minimum quantity of potable water of 25 litres per person per day or 6 kiloliters per household per month. Any person who needs more will come under privatisation model which key provisions on the existing law favors. About 38.4% of the population of South Africa who reside in rural communities are poor and mostly affected by inadequate water service delivery in that they cannot afford payment for water in excess of the minimum for which no fees is charged. As a concept, affirmative action is generally used in the context of work places to ensure that qualified marginalized groups have equal opportunities to get a job, but it is not yet investigated in the context of water service delivery. This study assessed laws governing water service delivery and explored how affirmative action can be used as an instrument to ensure the delivery of potable water to rural population in South Africa.

The task of this diploma thesis is to prepare the design of sanitary and gas pipeline installations in the assigned hospital building. The building has one underground and four above-ground floors. On the underground floor there are technical premises including a boiler room, hygienic facilities of staff and rooms for storage and cleaning. On the first floor there are ambulances of various kinds. Patient rooms are located over the second and third floors. Each room has its own built-in bathroom. There are also doctor's examination rooms and daily room of staff. On the fourth floor there is an ICU. In the theoretical part I deal with the legionella bacterium. I explain what causes this bacterium, what are the conditions for its reproduction, where it occurs and what measures will prevent its multiplication in water pipes. In the next part, I compare two possible variants of the solution of the design of water pipe routes with the subsequent selection of a more suitable option. The calculation part contains all the calculations used to design sewerage, water supply and gas pipeline, including their connection to utilities.
