KWA proposes new water treatment plant at Aluva

The Kerala Water Authority (KWA) has come up with a proposal to set up a new plant at Aluva where the agency has 3.5 acres of land at the site of existing treatment plant and pump house. A detailed project report on the new plant with a capacity of 150 million litres a day (mld) is being prepared. It is proposed to be a non-conventional plant that can be set up in less land with the technology of dual media plate settler.

KWA Central Region Chief Engineer G. Sreekumar told The Hindu that the advantage of the proposal was that the cost of the raw water pipeline to Kalamassery, the earlier site of the proposal, could be saved besides some of the distribution network lines too.

The cost of the project was yet to be worked out, he added. Discussions on the proposal would be held with the Minister next week, he said. The 225-mld plant at Aluva is overloaded to produce 290 mld, but it still falls short of the region’s demand by over 70 mld.

In spite of a two-river supply network, the city’s need has overshot the water supply from its two major plants — the 225-mld Aluva plant and the 100-mld plant at Maradu, where raw water from the Piravom river is brought into the supply network. While the Maradu plant improved water supply to West Kochi areas and gave a fillip to the demand-supply gap, the KWA failed to keep up with the growing demand by setting up the new plant at Kalamassery as proposed four years ago.

The KWA has now dropped the proposal of the water treatment plant at Kalamassery due to lack of availability of land.
