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.

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 »

Why wells should only be dug in a specific period of the year?

Understanding one of the main causes of wells’ drying in Sierra Leone, through an analysis of a water table movements.

A survey conducted by Inter Aide in 2010-2011 in 3 districts of Sierra Leone has highlighted that among 2028 hand-dug wells visited, 45% of them were not delivering water permanently all year long. | more information »

Hand drilling a shallow tube-well in Zimbabwe and fitting a simple “Bailer-bucket” for water lifting

The construction of the lighter duty, simple hand operated drilling rig has been described in another manual and was designed for drilling shallow tube wells in softer soil formations, which occur in some areas of Zimbabwe. Currently the drilling stems extend to a maximum of 12m. Staff members of the Ministry of Health and Child Welfare are familiar with local shallow ground water conditions in Zimbabwe. A depth of 12m is suitable for the use of this simple rig in combination with simple water raising devices like the “Bailer-Bucket” Pump and Blair Pump.
This manual describes the test drilling of a tube-well in Epworth, near Harare, Zimbabwe and the construction and fitting of a PVC casing and filter mechanism. It also describes the construction of a simple “Bailer-Bucket” pump and the head works at the head of the tube well. Of particular significance is the part played by the family itself by making the water raising device – a tubular bucket fitted with non-return valve and handle. The design of the “pump” is very simple and easily made within the home. The chances of continued operation and maintenance are this considerably improved. | more information »

Water Source Protection

Exploring ways to incentivise citizens and organisations to manage shared water resources in a fair, equitable way.

What is a Water Source Protection Plan?
A Water Source Protection Plan can be an extension of Water Safety Planning. The plan is an agreed statement between stakeholders that establishes objectives, actions, responsibilities and funding. However, it should go beyond the needs of the water infrastructure and actively look for win-win opportunities:

Key Messages
Important to sensitise land and water users in catchments to the impacts of their actions on others; aligning their self-interests with the wider collective interest is vital for avoiding conflict and protecting the rights of poorest, and the quality of the natural environment.

Bottom-up planning is essential where conventional permitting, monitoring and enforcement is ineffective or under-resourced.

More evidence is needed to show how effective locally-focused water source protection and resource management are when scaled up beyond resource-intensive pilot projects. | more information »

UPGro Catalyst projects

A synthesis and individual project activities and results

This report summarises the contribution to groundwater knowledge of the 15 catalyst projects funded through the UPGro programme between 2013 and 2014, plus the The Africa Groundwater Atlas and Literature Archive.
The projects worked in 12 individual countries (see next page - some countries had more than one project), and three had an Africa-wide focus or component.
At the time of writing two of the 15 projects are still running (Velasquez-Orta and Colombo). The Groundwater Atlas project will also continue as a major archive of African groundwater information. | more information »
