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.

Arsenic is widely distributed element in the earth’s crust and ranks twentieth in elemental presence. As a Group V element, arsenic exhibits a broad range of chemical reactivity and it is commercially used in alloys with lead. Arsenic in natural water has been reported from several countries including Bangladesh, China, Chile, Ghana, India, Nepal, Rumania, Taiwan, USA and Vietnam. In India, arsenic pollution is mostly of geological origin. However, ground water pollution of anthropogenic origin - due to industrial or mining waste - has been reported from Chennai in Tamil Nadu and Rajnandgaon in Madhya Pradesh.

Drilling Boreholes for Handpumps Working Paper 2 on Water Supply and Environmental Sanitation

Downloads: 387


Author: WURZEL, P.
Year of Publishing: 2001
Publisher: Skat
Institution: RWSN

This booklet seeks to suggest ways in which funds can be better used for making safe water available to the poor by illustrating how drilling costs can be reduced without compromising water quality, water quantity, or the productive life of the borehole. These arguments are directed towards the rural water supply sector as a whole. Those directly addressed are primarily decision makers, government civil servants, planners and implementers of water projects who are not experts in drilling, as well as technical people, project leaders, technical aid personnel etc. This publication is neither a detailed drilling manual nor a methodology of drilling methods.

The author draws on his extensive experience as a member of the UNICEF Water and Environmental Sanitation community. He hopes that his views and proposals will be a catalyst for change, and that this contribution will stimulate interest in experimenting with ideas on low cost drilling of boreholes for handpumps.

Institution: Silsoe College

The Low Cost Drilling Project (Cranfield University/DFID/Government of Uganda) is developing a modification of the traditional Asian sludging technology for use in Africa.
As part of the technology research a visit was made to north India to observe and measure various characteristics of this well drilling technique. The report describes these observations and draws conclusions for the Low Cost Well Drilling Project.
The method and equipment used by the Indian drillers (“mistries”) are set out, followed by an outline of the ergonomics and quantification of the work rates needed for hole cleaning and drilling. Drilling penetration rates in soft alluvium were observed to range from 16.5 to 45m per hour.
Traditional and more modern designs of casing and wellscreen, and the corresponding well completion methods, are described.
The cost of a 12m water well drilled by sludging in North West Bengal is estimated at Rs200 (approximately £3-4).
Practical conclusions are drawn in relation to equipment design for Uganda or elsewhere in sub-Saharan Africa.

In 2012, RWSN established Dgroups.org as its online electronic platform for membership and discussion. The groundwater and handpump groups have been among the most active communities. The number and depth of contributions has been rich, and several members have asked for a synthesis of the discussions. They main topics that emerged were:
1. Water Quality - particularly iron and pump corrosion
2. Procurement, Quality Control and Installation
3. Sustaining handpumps - what is the average lifespan of a handpump?
4. Handpump component failures and the need to redesign public domain designs
5. The politics of new pump designs: the Squirrel Cage Pump

This note may serve as guideline on how to combine roads and water harvesting. The investment in roads in almost any country far exceeds that in local water management or watershed protection. Hence roads offer one of the largest opportunities to secure local water supplies, if done wisely and in an integrated way. This document describes both the governance and proceses to combine road development with water management as well as how recharge, retention and reuse (3R) of water can be enhanced through improved designs.

Institution:

Groundwater supplies provide a significant proportion of rural dwellers in the developing world with access to a safe drinking water supply and will continue to do so in the near future. With the emergence of Self Supply and its increasing acceptance, low-cost handpumps have a role to play. Twenty five years ago the emphasis was on completely enclosed pumps (for drinking water only) to avoid the contamination of the well. Over the last 10 years, cheaper and simpler pump designs have become more acceptable. This development has been strongly influ-enced by the general recognition of the self-supply approach.

This guidance note points out the strengths and limitations of a number of low cost pumps. It provides an overview of the appli-cation, technical details, materials used, installation and mainte-nance, manufacturing requirements and costs of several low cost pumps, including information on the numbers installed and locations.

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.

Manual pumps have been used for centuries but this simple technology remains the mainstay of rural water supplies in many countries. The Handpump Technology Network (which later became RWSN) was set up in 1992 to promote collaboration and standardisation so that handpumps could provide more reliable and better quality rural water services.

This survey is aimed at practitioners in government, NGOs, private sector and development partners who are directly involved in rural water service implementation, or who are involved in the procurement of handpumps or spare parts (as either a buyer or seller).
