Developing Groundwater: A guide for rural water supply

Downloads: 85

Author: MacDonald A., Davies J., Calow R. and Chilton J.
Year of Publishing: 2005

In many rural areas, groundwater is the only feasible way of providing safe, reliable water supplies. However, developing groundwater is not always straightforward. To meet the targets set out in the Millennium Development Goals, more attention needs to be paid to finding and developing groundwater in a sustainable, cost-effective and participatory manner. Developing Groundwater provides a user-friendly guide to this key topic, bringing together for the first time the wide range of techniques required to develop groundwater for community water supplies. This practical manual gives information on effective techniques for siting wells and boreholes, assessing the sustainability of sources, constructing and testing the yield of boreholes and wells, and monitoring groundwater quality. The authors set the technical aspects of rural water supply firmly in their socio-economic context, so that readers can take proper account of community concerns as well as purely engineering questions. Packed with helpful illustrations this book is indispensable for all rural water supply project staff in developing countries.

Alan MacDonald is a hydrogeologist at the British Geological Survey. He has worked extensively in Africa, Asia and the Pacific in partnership with government departments, NGOs, research institutes and rural communities. Much of his work has focused on the practical issues of developing groundwater resources for rural water supply.

Handpump Standardisation in Sub-Saharan Africa: Seeking a Champion RWSN Publication 2015-1

Downloads: 1072

Author: MacArthur, J.
Year of Publishing: 2015
Publisher: RWSN

Handpump standardisation is the formal or informal mechanism that governs the varieties of community handpumps used within a particular country. In a handful of countries this also includes stand-ard handpump designs. With over a million handpumps in sub-Saharan Africa and new installations every day, handpump standardisation is still vital for the policy and practices of governments and implementing organisations. While rural water practitioners are polarised about the future of formal standardisation, the extent of informal standardisation is of significant importance to the sustain-ability of handpumps across the continent. Of the thirty-five countries in sub-Saharan using handpumps, formal standardisation has emerged in fifteen through regulations (nine countries), and endorsements (six countries). However in the remaining countries, informal standardisation determines what handpumps are installed where, either through recommendations (fourteen countries), or de facto standardisation (six countries).

Project Report from the ARIGA UPGro Catalyst Study

The city of Wajir in Northern Kenya, the capital of the county of the same name, has experienced rapid population growth in recent decades. The city has so far never had a reliable supply of clean drinking water or a sanitation system. To improve the situation, plans are currently considered to construct a water pipeline from Habaswein, another locale in Wajir County that is about 110 km away.

Regarding project design, two issues emerged as important. Poor project design was identified as one of the major risks to project success. Furthermore, activities to build consensus around the intervention and ensure that all stakeholders approve of the intervention is critical. Payments for Environmental Services were included in the model, but other benefit-sharing mechanisms, as well as awareness-raising measures, should also be explored.

Author: LECLERT, L
Year of Publishing: 2013
Institution: Government of South Sudan/Mott Macdonald

The aim of this status review, requested by DFID, was first, to assess the current operational status of Basic Services Fund (BSF) boreholes drilled between 2006 and 2012, through a borehole functionality assessment, and, second, to evaluate the impact of the recommendations provided to the implementing agencies, through requesting information and feedback on how they have been implementing their drilling activities and the soft component associated to it. The main limitations of this status review included the risks of biased information (as the data was collected mainly by the NGOs that constructed the boreholes) and the fact that it took place during the rainy season, reducing the possibility to access some boreholes.

There has been encouraging progress with access to safe drinking water and sanitation in both rural and urban areas since the United Nations Water Decade of the 1980s. However, more than 1 billion people around the world still lack access to safe water supplies and more than 2.4 billion are without adequate sanitation. A substantial majority of these people live in Asia where the lack of sanitation provision is particularly acute. In Africa, over one third of the population still remains without access to safe water and sanitation, and many of these can only be served by groundwater. The need for renewed efforts to improve the situation is recognised in DFID's recently published water strategy paper - ''Addressing the Water Crisis - Healthier and More Productive Lives for Poor People''.

These guidelines are an important contribution to risk assessment and the avoidance of the contamination of groundwater supplies from on-site sanitation. They have been development as part of a project funded by DFID through the water component of the Infrastructure and Urban Development Division's Knowledge and Research Programme.

Manual drilling was introduced into Guinea over the last three years. Previously there was no knowledge or experience of these technologies. About 50 manually drilled wells have been constructed to date, primarily for community water supplies. Although there are considerable funds available for further promotion of the technology, particularly through UNICEF, there is need to consolidate the experiences to date before moving on to another next phase of training and construction. It is also very important that the national government agencies responsible for rural water supplies as well as the local governments are given the opportunity to learn more about manual drilling technologies, including their potential and risks.

Phase I of the Danida assisted Rural Drinking Water Supply Project in coastal Orissa was implemented during August 1985 to March 1988. During this period approximately 1650 tube wells with handpumps were constructed in 3 blocks of the 20 blocks of the project area. By 1987, the functionality study and maintenance system indicated that pump were falling into disuse to deterioration of water quality in the wells. Offensive odour, unacceptable colour and taste were common features observed from these wells.

This report analyses the problem and put forwards practical recommendations.

This study is seen as an extension of a study carried out in 2009 by UNICEF, which mapped the handpumps and spare parts market in Africa as a whole. The study found that although large numbers of handpumps are sold in Africa each year, availability of spare parts at community level is still a great challenge. In addition, supply chains for handpumps and spare parts are normally separated, and there are challenges with availability, affordability as well as sufficient community structures to ensure demand.
