WINDHOEK, 28 DEC (NAMPA) The Calueque scheme, which is the source of water supply to the north-central parts of the country, is currently under repair due to heavy leakage.
A letter sent by NamWater on Friday to Minister of Agriculture Water and Forestry, John Mutorwa, said the pumping lines from the two-water abstraction pumps have been leaking heavily, minimising the normal hydraulic flow into the canal.
A lot of water is being wasted and seeping back into the pumps and switchboard building, while some is collecting into pools outside, the letter outlined.
It stated that NamWater has appointed a contractor, who is currently onsite, to fix the pumping lines before it gets worse.
The contactor will repair one pump at a time, leaving one pump in operation.
The provision of raw water supply to the NamWater Plant for production is currently dependent on one pump at Calueque, said the letter.
The note further stated that the repair work is being conducted within the pipe underground, creating uncertainty about the successful execution of the undertaking.
The letter however explained that although the scheme is vulnerable, it is not under critical threat and the repair work on both pumps is expected to be complete in four weeks.
The Olushandja Dam, which is a source of emergency and security for the availability of raw water supply to the north-central areas, will assist in boosting the flow and volume in the canal.
This will however negatively impact the small scale irrigation farmers around the Olushandja Dam, as it will deprive them of water.
The reduced water supply will directly affect the Omusati Region, Etunda Irrigation Scheme and Olushandja horticulture farmers.
Efforts to get comment from NamWaters communication department regarding the progress of repair work and water supply disruption proved futile as everyone in the department was said to be on leave.
