Reconstruction of a water treatment plant in Sri Lanka

The goal of this project was the reconstruction of the Kalatuwawa and Labugama water treatment plants supplying drinking water for Colombo city. Keeping the plant functional throughout this process was both challenging and necessary. Design, manufacturing, transport, installation and commissioning were a success and allowed for a smooth transition to running on full capacity.

Water treatment technology:
A complex process of sedimentation, flotation, filtration, chlorination and sludge treatment was implemented in order to achieve the following drinking water production capacity: Kalatuwawa – 90 000 m3/day and Labugama – 60 000 m3/day.
