ECONOMYNEXT – Sri Lankan irrigation authorities are to widen a canal and shift a flood gate as part of measures to minimise flooding in the capital Colombo, parts of which went under water during heavy rains in recent years, causing heavy economic damage.

The project comes under the Ministry of Megapolis and Western Development, which is in charge of developing Colombo and its suburbs as a modern urban ‘Metropolis’.

Under the project, obstacles to the flow of the Kiththampahuwa canal near the Sedawatta – Ambathale road will be removed by rebuilding the flood gate closer to the outfall and strengthening the banks of the canal.

It is being done with the support of the climate action committee of the department of irrigation.

The Kolonnawa Canal Diversion Scheme has been identified as a major development activities under the Metro Colombo Urban Development Project, aimed at mitigating floods, a statement said.

“Under this project, it is expected to widen the existing canals to improve the flow of storm water in the Colombo area during periods of low water levels in the Kelani River and also to make arrangements to mitigate the flood condition occurring in the Kolonnawa area during periods of high water level.”
