Well rehabilitations in Ghana

In the Brong-Ahafo region, defective and clogged water wells are being rehabilitated to increase their yield and sustainably improve the water supply.

The existing drinking water wells in the Brong-Ahafo region of Ghana are frequently only partially operational or entirely out of service due to issues such as poor water quality, faulty pumps or insufficient water yield. Additionally, the wells are often affected by blockages resulting from lime deposits as well as iron and manganese oxides.

In order to enhance the drinking water supply, the University of Bayreuth’s regional chapter of the German association "Engineers Without Borders" (German: Technik ohne Grenzen e.V.) is collaborating with students from Sunyani Technical University on a well rehabilitation project which is supported by the Wilo-Foundation. Since 2016, drinking water wells identified through data collection and analysis have been rehabilitated and their yield has been increased. With the help of the eco-friendly chemical Wessoclean, blockages in the wells were dissolved and their pumping performance enhanced.

Over the past years, access to water has been successfully restored in 12 communities across the Bono and Ashanti regions. The project originally aimed at repairing and rehabilitate six boreholes, but due to high demand from surrounding communities, the scope has since expanded to 16 boreholes. Many of these boreholes had been non-functional for many years, making the repairs complex and challenging. Thanks to the implemented measures, the performance of the wells has significantly improved, allowing villagers to draw a much larger quantity of drinking water.

Our funding partner

The non-profit association Technik ohne Grenzen e.V., Höchstadt an der Aisch (Germany), is committed to improving living conditions in developing countries — in a practical, sustainable, and locally adapted way. The association pursues three core approaches: effective development cooperation using available resources, education for self-help, and sustainable structures. True to the motto “As technical as necessary, as simple as possible,” technology enthusiasts — from students to professionals — apply their expertise in a targeted manner to provide global support for self-help.

UN Sustainable Development Goals

The UN 2030 Agenda for Sustainable Development with its 17 Sustainable Development Goals (SDGs) forms the global framework for action for socially, economically and ecologically sustainable development. Our funding commitment also supports these sustainability goals. With this project, we are making a contribution to achieving the following SDGs:
