La Stratégie Nationale de Surveillance de la Qualité de l’Eau de Consommation, adoptée en 2012 impose aux producteurs-distributeurs d’eau destinée à la consommation humaine de se doter d’un Plan de Gestion de la Sécurité Sanitaire de l’Eau (PGSSE) ; d’effectuer régulièrement des inspections sanitaires des installations d’approvisionnement en eau potable et d’effectuer régulièrement des contrôles de la qualité de l’eau distribuée à la population.

Quel est l’objectif du PGSSE ?
Le PGSSE est un document qui comporte l’ensemble des mesures préventives et correctives permettant de réduire les risques de détérioration de la qualité de l’eau identifiés entre la zone de captage et le point de distribution de l’eau au consommateur, en passant par les unités de traitement, les points de stockage de l’eau traitée et le réseau de distribution. L’objectif de la démarche est de garantir en permanence la sécurité sanitaire de l’eau de boisson distribuée et ainsi de préserver la santé des populations.

InterAide Support to Operation and Maintenance of rural Water Supplies in Malawi in 2008 Member's Experiences No.1

Year of Publishing: 2009
Publisher: RWSN/Inter Aide
Institution:

The NGO InterAide has experience of supporting operation and maintenance of rural water supplies. Initiatives started in 1999 in Lilongwe and Zomba districts where there are now a total of 59 shops selling handpump spare parts and 84 private sector area mechanics repairing handpumps. Based on these fruitfull experiences InterAide started (first with European Union funds, then with Pro Victimis Fundation funds) a new Operation and Maintenance project in 2008 in the three districts of Mchinji, Dowa and Salima located in the central region of Malawi. As about 80% of handpumps installed in Malawi are Afridev, InterAide decided to initially focus on this hand pump.
This report provides a description of the project, including the financial and human resource inputs.

The Zimbabwe Bush Pump: Mechanics of a Fluid Technology Social Studies of Science

Author: DE LAET, M. & MOL, A.
Year of Publishing: 2000
Publisher: SSS and SAGE Publications
Institution:

In this paper we investigate the intricacies of an admirable water pumping device – the Zimbabwe Bush Pump ‘B’ type – so as to find out what makes it an ‘appropriate technology’. This turns out to be what we call the ‘fluidity’ of the pump (of its boundaries, or of its working order, and of its maker). We find that in travelling to intractable places, an object that isn’t too rigorously bounded, that doesn’t impose itself but tries to serve, that is adaptable, flexible and responsive – in short, a fluid object – may well prove to be stronger than one which is firm. By analyzing the success and failure of this device, its agency and the way in which it shapes new configurations in the Zimbabwean socio-technical landscape, we partake in the current move in science and technology studies to transform what it means to be an actor. And by mobilizing the term love for articulating our relation to the Bush Pump, we try to contribute to shaping novel ways of ‘doing’ normativity.

Manually operated Pumps for Drinking Water Supply in Madagascar An overview July 2004

Institution: Skat/UNICEF

UNICEF Madagascar has been supporting rural water supply and sanitation activities in Madagascar for over ten years. The Water, Environment and Sanitation (WES) desk of UNICEF works with Ministry of Energy and Mines (MEM), Government of Madagascar, on a number of water supply initiatives. One of these projects, in the southern part of Tulear Province (also known as the South – Sud), comprised of drilling wells and installation of 150 India Mark II handpumps in the vicinity of Antanimora. This is referred to as the AAEPA Project later in this report. The installation of handpumps in the AAEPA Project was completed during 1994-96 and has since then been supported by UNICEF for its operation and maintenance (O&M)
with supply of spare parts. Over the years, this project has undergone reorganisation a number of times.
The AAEPA Project was evaluated by the World Bank in early 2004. The evaluation noted that the spare parts distribution was not well organized and was subsidised. It was also noted that the India Mark II handpumps lacked a country level distribution network.

This field note is written for water well drilling enterprises as well as other agencies which manage, or are involved in drilling projects. Using a step-by-step approach it gives clear guidance on how to cost and price the construction of drilled water wells. It also provides tips on business management with an emphasis of the realities faced in many countries in sub-Saharan Africa. Once you are familiar with this field note, you will be in a much stronger position to calculate drilling costs, consider prices and deal with business realities.

The Rural Water Supply Network (RWSN) is a global network of professionals and practitioners. It works to raise standards of knowledge as well as technical and professional competence in rural water supplies and thus fulfil the vision of sustainable rural water services for all.

The year 2013 witnessed the dramatic growth in the number of members from 2,567 to over 5,125. Members are from 124 different countries. The network now also provides the opportunity for organisation membership, a mechanism that should strengthen RWSN and improve its vibrancy over the coming years.

Confidence in online exchange and sharing has grown, evidenced by extensive participation in e-discussions, whether formally structured, or as individuals respond to each other’s queries and comments. The sustainable Groundwater Development, Handpump Services and Mapping communities have been notably vibrant in 2013.

Sustainable groundwater development is fundamental in order to provide universal access to safe drinking water. This document, The Code of Practice for Cost Effective Boreholes provides a basis for the realisation of economical and sustainable access to safe water. The term “cost-effective” means optimum value for money invested over the long term. Boreholes are drilled to function for a lifespan of 20 to 50 years. Thus, the lowest cost is not always the most cost-effective, particularly if construction quality is compromised to save money. Cheap drilling or poor construction quality can lead to premature failure of the well or contamination of the water supply. Boreholes that are subsequently abandoned by the users are clearly not cost-effective.

The Code of Practice for Cost-Effective Boreholes has been officially endorsed by the German Federal Institute for Geosciences and Natural Resources (BGR).

La réalisation d’ouvrages pérennes d’exploitation d’eau souterraine est fondamentale pour l’accès universel à l’eau potable. Ce docu-ment, Le Code de bonnes pratiques pour la réalisation de forages présente un cadre pour l’accès à l’eau sur la base de critères écono-miques et de santé publique. Ces bonnes pratiques visent à optimi-ser le rapport qualité/prix de l’investissement à long terme. Les forages étant construits pour fonctionner sur une durée de vie de 20 à 50 ans, le plus bas prix ne représente pas toujours l’optimum économique, en particulier lorsque la qualité des ouvrages est sacri-fiée afin d’économiser sur les investissements. La réalisation de fo-rages très bon marché ou de mauvaise qualité peut engendrer des dysfonctionnements prématurés ou la contamination de la res-source en eau. Ceux-ci sont par la suite abandonnés par les usagers et n’ont pas à l’évidence un bon rapport coût-efficacité.

A utilização sustentável das águas subterrâneas é essencial para permitir o acesso universal a água potável. O presente documen-to, o Código de Boas Práticas para a Obtenção de Furos Rentáveis, constitui um ponto de partida para a concretização do acesso económico e sustentável a água potável. O termo “rentáveis” re-fere-se à maximização do investimento realizado a longo prazo. Os furos são feitos para durar por um período entre 20 e 50 anos. Assim, o custo mais baixo nem sempre é o mais rentável, essenci-almente se a qualidade da construção for comprometida para poupar dinheiro. Uma perfuração barata ou a fraca qualidade da construção podem levar a uma falha precoce do poço ou conta-minação do abastecimento de água. Se os furos forem abando-nados de seguida pelos seus utentes, claramente não serão ren-táveis.

O Código de Boas Práticas para a Obtenção de Furos Rentáveis foi oficialmente aprovado pelo Instituto Federal de Geociências e Recursos Naturais da Alemanha (BGR).
