In Zanzibar, Tanzania, the Urban West Province of Unguja, the largest island in the Zanzibar (island region), is expected to experience a further increase in water demand due to population growth. In Zanzibar, the water source is dependent on groundwater, but there is no accurate data on the amount of water resources available, and the amount of water that can be pumped is unknown. Under these circumstances, immediate development of new water sources poses risks such as salinization.
Therefore, it is necessary to first renew the water distribution pipe network, which is said to have a leakage rate of 60%, to alleviate the tight water supply and demand situation, and to improve the yield rate for proper maintenance of water supply facilities by the Zanzibar Water Authority.
This cooperation will improve water distribution facilities, rehabilitate existing wells, and upgrade and renew the water pipe network in Werezo West, Werezo High District, and Migombani West Water Distribution Area in Urban West Province, Zanzibar Unguja Island, thereby improving yield and reducing leakage rates, thereby contributing to the spread of safe and stable water supply services. This will contribute to the improvement of the living environment of residents in the target areas.
