THIRUVANANTHAPURAM: The Kerala authority (KWA), which was all set to call tenders for Neyyar scheme, is revising the project incorporating the suggestions made by Kerala dam safety authority. KWA is planning to introduce floating pumps instead of an open well to draw water.
The water supply project, which aims to generate 120 million litres of water per day, intended to draw water from .
As per its original plan, an open well will be constructed near the dam to draw water to the treatment plant. However, KDSA chairman C N Ramachandran Nair, who visited Peppara and Neyyar dams recently, suggested floating pumps instead of well.
The KWA is in the process of revising the estimate by incorporating the changes. The new estimate needs to get technical sanction. The project was expected to be tendered last month.
The project got delayed earlier due to delay in handing over the land belonging to the irrigation department, which was encroached upon by a private party.
Water resources minister K Krishnankutty had recently said that the scheme will be a long-term solution for the shortage in the city.
Of the total 120 mld, five mld each will be distributed to four adjoining panchayats. Remaining 100 mld will be distributed to the city. Currently, 270 mld water is distributed in the city.
Around Rs 60 crore will be required for setting up the treatment plant. However, the cost of laying a pipeline to bring the water from Neyyar to PTP Nagar is estimated to be around Rs 250 crore.
The Neyyar dam has been used solely for irrigation purpose so far. The KWA’s plan to utilize water from Neyyar dam for drinking will put an end to its dependence on Peppara as the single source of water for the city.
At present, elevated areas of the city are facing drinking water shortage. Sources in the KWA said that overuse of water during summer and increase of population were reasons for the scarcity in those areas.
