Objectives

(i) Increase area under irrigated agriculture by 9,040 hectares in 13 villages in Butiama and Serengeti Districts and more when fully developed. In turn, this will contribute 21.1 % of the annual area to be developed under the National Irrigation Development Strategy.
(ii) Increase installed capacity of hydropower to national grid by 2.8 MW from Borenga multipurpose
reservoir.
(iii) Increase water supply and sanitation coverage in the region by supplying potable water to 17 villages with total population of 100,000 in Butiama, Serengeti and Tarime Districts.
(iv) Improve conservation of the watersheds within the project area.
(v) Drought and floods control through constructed Borenga MSR; and
•(vi) Build institutional and human resource capacities at local and regional levels for the sustainability of the irrigation and water supply scheme.
