Every year, most parts in South Rift region receive a considerably higher amount of rainfall than most parts of the country due to its highland location. The region gets about 760mm (30 inches) of rain per year, making it one of the wettest in the country.
Despite this apparent abundance, however, there is a serious water problem that has for many years required intervention to ensure uninterrupted water supply to the thousands of homesteads and critical installations across the region.
