A flood protection wall to be constructed

The Kelani basin highlights the need to scale up the existing Climate Resilience Program with focus on mitigating urban flooding. As such, a flood protection wall will be constructed, in the interim. As a long term measure, new multi-purpose reservoirs will be built upstream at Wee Oya, Nawatha, Holombuwa and Reucastle to enhance the water retention capacity. A similar mechanism will be looked into with regard to other perennial rivers including, Kalu, Nilwala and Gin rivers. – Rs. 4,900 Mn
