The Ndhiwa Project Schools Rainwater Harvesting 2011

During 2011 we will be supporting the upgrading and installation of rainwater harvesting at 6 primary schools in the Homa Bay district of West Kanyamwa, Kenya. Total attendance at these schools is currently 3400 pupils although school rolls are rising.
V West Kanyamwa lies at around 1250m above sea level and has a gently undulating terrain. Temperatures are highest between December and March with maximum temperatures being experienced in February. The long rainy season is between February/March and May/June. The short rains fall in August/September. The average rainfall is around 500mm per annum.

There is no piped water or sewerage. Much of the population collect their water from small ponds, rivers or puddles. A Government survey in 2000 concluded that 38% of the population had access to safe water, and 36% of homesteads had access to a latrine.

Within West Kanyamwa there are two secondary schools and 11 primary schools. There are no higher-level training institutions.

The initial intention of this project is to provide water for handwashing to improve hygiene standards at the schools and close to the latrines. Where it is appropriate and safe, water will also be tested and if necessary treated for drinking.

Some of the schools already have rainwater harvesting which needs improving, such as this school at Sibouche where old concrete tanks are no longer in use. Hand wash stands and tanks are proposed here.

At the school at Mbani where water catchment is currently limited, the classroom will be provided with guttering, pipework and diverter to a 10,000 litre storage tank and protective cage to prevent water theft.
