Sustainable Groundwater Development for Rural Water Supplies

Groundwater is playing an ever important role for drinking water supplies, particularly in rural areas. In many countries, there has been a switch from using unprotected surface water to protected groundwater. Groundwater is fairly ubiquitous, but its conditions vary enormously and exploitation is often undertaken with limited understanding of hydrogeology and without sufficient evaluation of the resource, especially in developing counties. The days when pumps could be installed without considering the groundwater resource are over. Groundwater scarcity and pollution are becoming a major concern in some places. There are regions where groundwater quality is not fit for human consumption due to a high level of arsenic, fluoride, iron or nitrates and there is need for professionalism and vigilance to ensure that infrastructure is built to last, and that borehole provision is cost-effective. Basically, without proper drilling supervision, and quality pumps, universal access to a safe drinking water supply will never be met. RWSN’s Sustainable Groundwater Development theme sets out to ensure that goundwater resources are properly considered and sustainably used for developing drinking water supply sources.

Procurement, Costing & Pricing and Contract Management of Borehole Construction - Zambia Short Course Report

Striving for Professionalism in Cost Effective Boreholes in Zambia

The Ministry of Local Government and Housing (MLGH) Zambia and the Water and Resources Management Authority (WARMA) weresupported by the cooperation of UNICEF and Skat Foundation to strengthen capacity in the country with respect to siting, drilling, supervision, procurement and contract management. The support included the delivery of a five-day short course to 38 participants in Zambia on drilling procurement, costing & pricing and contract management. This report presents the proceedings and outcomes of the course. | more information »

Groundwater Resources of Malawi

This report comprises a summary and interpretation of all available archive hydrogeological data from boreholes and wells up to December 1981. In addition, information has been obtained from the more recent work of the Groundwater Section, both in its general groundwater development programme and in the specific investigations into key aspects of the hydrogeology, primarily aquifer properties and water level fluctuations. | more information »

Manual for Integrated Projects for Rural Groundwater Supplies

This Manual has been prepared so that Malawian professional staff can effectively and economically provide domestic water supplies to the large number of Malawi rural villages that depend on groundwater. This Manual is distributed at the seminar so that other countries may benefit from significant advances in rural groundwater development which have taken place in Malawi over the past two years with the assistance of the United Kingdom Government and United Nations Development Programme. The Manual is based on work carried out by staff of the Department of Lands, Valuation and Water in co­ operation with staff of the UKODA and UNDTCD and the participation of Malawi's industrial sector. | more information »

Field Study Investigating the Potential of Water Quality

Testing to Predict Corrosion in Boreholes in Northern Uganda

Water sources are often abandoned by communities for two reasons: (1) the aesthetics of water quality that affects user acceptability and (2) the breakdown of pump parts that prohibits use of the borehole. Both can be related to the aggressiveness of water and both are important. Electroconductivity and pH and indices can indicate the potential of galvanic corrosion and electrochemical corrosion, respectively. Electrochemical corrosion contributes most to the high levels of iron from boreholes. The purpose of this study was to investigate the efficacy of pH strips in predicting groundwater pH and aggressiveness, compare the reliability of three different pH test strips to a Hanna pH probe, determine the origin of iron measured in boreholes, and make relevant recommendations. | more information »

Upgraded Family Wells in Zimbabwe (2012)

A study of Upgraded Family Well technology and training

Several years ago Zimbabwe embarked on a program of upgrading family owned wells. This program was fully endorsed by the GOZ and operated under the MOHCW. The program has been well documented in papers and other publications. This program was based on the fact that for many decades individual families had chosen to upgrade their own wells privately and outside the formal GOZ rural water supply and sanitation program. In the early 1980’s the number of family owned wells in Zimbabwe was estimated to be at least 100 000. Many of these were lined with bricks and had some form of head works. Many were fitted with windlasses – a legacy from the mining industry. The windlass made the bucket easier to lift and also retained the rope or chain in a hygienic position above ground. However the majority of family owned wells were poorly protected and open and were subject to contamination, especially during the rainy season and were also dangerous for children. | more information »

Supply Chains for Rural Water Supply in Uganda

HTN Report

The objective of this study is to review the status of supply chains for spare parts with the goal to identify appropriate interventions that will improve availability of spare parts. Supply of equipment cannot be de-linked from supply of spare parts therefore the study looks into the supply of equipment as well. | more information »

Evaluation of Hand Augered Well Technologies’ Capacity to Improve Access to Water in Coastal Ngöbe Communities in Panama

MSc thesis submitted to University of South Florida 2014

In Panama, the indigenous Ngöbe people in the ÑöKribo coastal area are a group disproportionately affected by a lack of improved access to drinking water and challenges to the feasibility of piped gravity fed water systems that typically serve the rest of the country. An NGO aiming to ameliorate this situation introduced two improved groundwater supply technologies to the region: bailers and EMAS hand pumps. This study assesses the comparative performance of these systems while evaluating the respective performances of existing water sources, using the wide variety of quantitative and qualitative data obtained.

Elements of Sustainable Solar Water Pumping System Design

Synthesis and presentations from 2015 WEDC Conference Workshop

Technological advances over the past decade have made solar water pumping a viable option for potable water service delivery in rural settings. Solar pumping is an especially attractive alternative when poor groundwater quality or high population density and growth limit the applicability of boreholes fitted with handpumps. However, globally-accessible resources that specifically speak to the various technological, financial, social, environmental, institutional, and operational elements of sustainable solar pumping designs are limited. This workshop provides participants with an opportunity to explore various aspects of holistic design of solar pumping systems through guided group discussion. | more information »
