Impacts of Solar Water Pumping: Case of Preiswerk Girls, Ifakara

Tanzania Renewable Energy Association (TAREA) partnered with URBIS Foundation, a German NGO to support the Preiswerk Girls Secondary School, in Ifakara, Tanzania with a solar photovoltaic pumping system 1.2kWp that delivers 20,000 litres of water per day.

The school used a diesel generator to run the water pump. The cost of running a diesel generator made the water supply at the school unreliable. The students had to collect water from the stream near the school. The water from the stream was not safe, Students were often sick from typhoid and Urinary Tract Infections (UTI).

Also, the use of a diesel generator polluted the environment through the emissions of greenhouse gases.


The installation of the solar water pumping system changed the lives of the girls. The water which is pumped from the protected water borehole is safe and has resulted in the eradication of typhoid and UTI. The girls can live hygienically.

Preiswerk Girls plant trees and grow vegetables. The emission of 14,086KgCO2/year has been avoided.
