Water supply and maintenance project – Kabonwule, Northern Ghana

The village of Kabonwule in the Northern Region of Ghana suffers from water shortage during the dry season. Additionally, the highly extended fluoride content in the ground water leads to health problems. Our three Ghanaian members Joseph, Edmund and John enabled a new source of water by the provision of a new pump for a dysfunctioning borehole and trained the inhabitants in filtration of the drinking water by using a readily accessing filter material to reduce the fluoride content. The following video shows their impressions in Kabonwule.
