Accordingly the authorities say the spill-ways of the dam would be opened in accordance with the laid down procedure to carry out a full load test on the spillway gates together with assessment of any effects of such emergency discharge of water on the dam to any structures downstream.
This test, the authority said in a statement issued here on Thursday should have been carried out earlier before the handing-over of the dam by the Chinese contractors who built the dam, but was put off due to the inadequacy of water in the dam.
According to the statement, the BPA and the Chinese engineers, Sinohydro Corporation Ltd had come to agreement to put on hold the full load testing until such time that the water levels reached the required level.
“The BPA, as the custodian and manager of the Bui Hydroelectric project has the responsibility to control the flow of water to ensure that the safety of the Bui Dam and its structures are not jeopardized,” the statement said.
Sinohydro Corporation of China, in December 2013 handed over the Bui Generating Station (Bui GS) to BPA after completing the construction of the 400 mega watts dam.
“At the end of 2015, inflow season the Bui reservoir has for the first time since impoundment, reached an acceptable level for the conduct of the deferred tests,” the statement added, announcing December 14 to December 16 as the period for the spillage.
The BPA is therefore carrying out a sensitization exercise in all communities downstream to avert any disaster during the spillage. Enditem
