Until 2006, the closest safe drinking water source was a single hand pump -1.6 km further down the hill. Each day the 500 people in the village had to walk over 3 km to the pump and back in order to collect water.
In 2006, Frede Bosteen from DENG Limited in Accra, identified the site as suitable for a Mono Solar Powered Water Pump. The old hand pump was replaced with a 600 Watt tracking Sun-Sub pumping system sponsored by Danida. The water level in the borehole is 35 m below ground and the Sun-Sub pump was able to push the water an additional 50 m up the hill via a 1.6 km long pipe, into the village. The average annual water supply from the solar pump is
approximately 7500 litres per day at a total pressure of 86 m.
The pump is used to fill a number of water tanks located around the village. Water is then gravity fed from the tanks to nearby water stands. The built in pressure cut-off feature of the Mono Sun-Sub system made the level control in these tanks very simple. Once all the tanks are full the pump automatically turns off to prevent
wastage of the valuable water source.
In 2007 the National Museum of Denmark funded the restoration of the buildings at Frederiksgave. The site will become the Sesemi Museum and will contain many historic items from the original Danish plantation. This construction work was only possible because of the water supply available in the local village. An additional
water tank has been installed at the site to provide water for the construction and later for the requirements of the Museum.
The solar powered water pump has helped to transform this small community in Ghana by providing safe drinking water throughout the village. They no longer have to carry heavy water containers up and down the hill. Construction of the new museum has provided employment in the village and more opportunities will become available when it opens at the end of this year.
