Jacob, N. (2021) Synthesis Document Thematic Discussion on Expertise and resources needed for inclusive and lasting water and sanitation
Panchayats have been assigned the responsibility for executing rural water and sanitation. To do this successfully as equal partners with the government and engineers, they need a lot of support over the long term. The government and NGOs who will support them have important roles to play to ensure quality water and sanitation services are provided in the long term in an an equitable manner.

USAID, AAE (2021) West Africa Municipal Water, Sanitation and Hygiene Activity (in English and French) Role of municipalities in the provision of water and sanitation services in Côte d'ivoire
DECENTRALIZATION The beginnings of decentralization in Côte d'Ivoire date back to the colonial period, when the country was a French colony with the existence of mixed communes and municipal councils (partly elected and partly appointed). Medium-sized communes were run by councils headed by “Mayor Administrators” appointed by the Central Colonial Government. Large communes were administered entirely by elected municipal councils. Today, with the revitalization and […]

Smout, I., Shaw, R. (1991) Small Earth Dams
This Technical Brief is concerned with the typical small dam (up to about three metres high) which is built across a stream to form a reservoir. It provides guidance on planning, design and construction, but professional help should always be sought before building any dam whose failure could endanger lives, property or the environment. Care must also be taken to avoid the health hazards of […]

Adank, M., van Koppen, B. & Smits, S. (2012) Guidelines for Planning and Providing Multiple-Use Water Services
The multiple-use water services (MUS) approach is defined as an approach to water services that considers the multiple needs of (poor) water users, who take water from a number of sources, and communities’ own priorities as the starting point for investments in new infrastructure, management arrangements, the rehabilitation of existing infrastructure, or for improvements in management and governance (Van Koppen, 2006). MUS started with the […]

A guideline based on the Swiss Re 2007 award winning pilot project “Water harvesting to improve livelihoods in southern Ethiopia: from pilots to mainstream” and large-scale implementation of sand dams in Kenya. In the Kituï District of Kenya the SASOL (Sahelian Solutions) Foundation began constructing sand storage dams in 1995. Since this period, over 500 sand storage dams have been constructed. These vary in size […]

Previous blinded trials of household water treatment interventions in low-income settings have failed to detect a reduction in child diarrhoea. Technological advances have enabled the development of automated in-line chlorine dosers that can disinfect drinking water without electricity, while also allowing users to continue their typical water collection practices. We […]

Decentralized drinking-water systems are an important element in the process of reaching the Millennium Development Goals, as centralized systems are often deficient or non-existent in developing and transition countries (DC and TC). Most water-quality problems are due to hygiene factors and pathogens. A range of decentralized systems is available to counter these problems, including thermal and/or UV methods, physical removal and chemical treatment. This review focuses […]

Seawater desalination facilities require an intake system capable of providing a reliable quantity of clean seawater with a minimum ecological impact. To meet these objectives, it is essential that a thorough assessment of site conditions be conducted. Physical characteristics, meteorological and oceanographic data, marine biology, and the potential effects of fouling, pollution, and navigation must be evaluated, and an appropriate intake design employed. As the […]

Oxfam (2007) Household Water Treatment and Storage
Historically, interventions to provide people with safe water have focussed on improving water sources. However there is now a consensus among the WatSan community that even if the drinking water source is safe it can easily be re-contaminated during its transportation and storage in the household (Clasen and Bastable, 2003). A safe water intervention should therefore begin with an improved water supply and be followed […]

Nkwonta, O., Ochieng, G. (2009) Roughing filter for water pre-treatment technology in developing countries: A review
Roughing filtration can be considered as a major pre-treatment process for wastewater, since they efficiently separate fine solids particles over prolonged periods without addition of chemicals. This review article summarizes and evaluates modifications to roughing filtration technology, which may address these limitations without compromising the simplicity of the treatment process. Successful modifications includes broken burnt bricks, charcoal and coconut fibre as filter media. The paper […]

NGWA (2013) Brackish Groundwater NGWA Information Brief
Brackish water does not have an exact definition, but it is typically defined as distastefully salty but less saline than seawater (between 1,000 to 10,000 ppm [parts per million] in total dissolved solids [TDS]). In addition to certain surface water settings such as estuaries, brackish water can be found in aquifers. In some regions of the country with limited availability of freshwater, desalination of brackish […]
