Borenga Dam and Mara Valley Multipurpose Water Resources Development Project
BIP_NELSAP_011 Water Agricultural irrigation and drainage
Overview
Summary
The Mara River Basin Project contributes to improved living conditions of the basin communities by creating an enabling environment for sustainable development-oriented investments and building capacity of riparian staff and communities in integrated water resources management and development. The project is preparing several investment proposals in the fields of water infrastructure, watershed management and irrigation infrastructure for subsequent funding within a consistent basin development strategy. This primarily irrigation project includes the Borenga Dam, will benefit 100,000 people, irrigate 8,340Ha in 13 villages of Serengeti and Butiama Districts, 2.85MW hydropower, water supply to 18 villages in Serengeti, Butiama and Tarime Districts in Tanzania.

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.
