Initially, the school faced problems of acute water shortage and students would fetch water in the river, this was only solved through the assistance of the late Gitu who allowed the school to construct a water pump in his land. To date,the school still benefits from this water supply.With the construction and office opening of the first dormitory in 1968, the school started to accommodate more boarders. Initially students used to sleep in a 'granary' which had been donated by the late Mr. Gitu. It started as a purelv harambee school and later became a government assisted school. With development of more accommodation facilities, the school grew from one streamed school to become a four streamed school.
