Mozambique seeks outlet rehab at Massingir Dam

Mozambique’s water directorate invites applications for pre-qualification to rehabilitate the bottom outlet works of Massingir Dam on Mozambique’s Olifants River. Responses are due December 11, 2009.

The African Development Bank (AfDB) approved a US$20.6 million loan for the work in July. (HydroWorld 7/17/09) Massingir’s outlet pipes ruptured in 2008, a year after US$60 million in dam rehabilitation work had been completed with funding from AfDB.

The emergency rehabilitation project is intended to prevent the dam’s total collapse in the event of a heavy downpour. It also is to improve the dam’s operational efficiency, improving food production and living standards of area farmers in Southern Gaza Province.

The dam’s original leakage, which began within months after the dam was completed in 1977, prevented the reservoir from holding more than 40 percent of its capacity. That reduced irrigation potential 60 percent and delayed a plan to build a 40-MW hydropower plant. Upon completion of the leakage repairs the reservoir was refilled until the rupture of Massingir’s outlet pipes in May 2008.

Pre-qualification documents may be obtained from the address below for US$100 by request labeled “Request for Pre-qualification Documents for Massingir Dam: Rehabilitation of Bottom Outlet Works.”

Applications for pre-qualification are due by noon December 11 to the address below.
