Solar powered pumping at depth

Nyarugusu camp, Tanzania, 2016

Oxfam and solar partner Epicenter Africa have successfully installed one of the largest ever solar arrays in a refugee camp – proving that solar technology is now effective at pumping from a depth of 103 metres.

Nyarugusu camp lies along the Tanzania-Burundi border, and houses 155,000 Burundian and Congolese refugees who have fled violence in their own countries. The camp has three boreholes and a fourth with a surface pump powered by solar energy that is saving $34,000 annually in running costs.
