Water supply across all three sectors of Salt Lake will be stopped on Saturday as a couple of new pumps and bell mouths will be installed in the reservoir of the Central Park water pumping station.

Bidhannagar Municipal Corporation (BMC) officials said people in some blocks would get their morning water on Saturday from 6.30am to 9am.

In the evening, water will be pumped to different blocks from 5pm to 6pm after which the service would remain suspended till Sunday morning.

On normal days, apart from 6.30am to 9am, water is also supplied from 11am to noon and from 4pm to 6pm.

A bell mouth spillway in large reservoirs is designed like an inverted bell where water can enter from the entire perimeter of the reservoir once it is filled and naturally flows into the pipes of the reservoir after which it is pumped out, an engineer of the Kolkata Metropolitan Development Authority (KMDA) that will install the two spillways, said.

Apart from this, two new pumps will also be placed at the pumping station to ensure that they can handle the pressure of the water better than the older ones.

The Telegraph had reported on Wednesday that new valves had been installed at all the pumps of the station because of which water supply was interrupted on that day as well.

According to an official, Salt Lake is now getting most of its water supply from the New Town water treatment plant. Hence, the pumps at the Central Park station will need the new bell mouth spillway, pumps as well as  valves as the water pressure is much higher than compared to what was supplied from Tallah or drawn from underground.

Officials of the water supply and distribution department at the civic body said the water pressure in the other distribution lines of the Central Park pumping station was falling because of leakage through the older valves and pumps that were not able to withstand the pressure.

“The volume of water has gone up but the older valves cannot sustain the pressure because of which there are leaks. This needs to be eliminated and we will be able to do so once the valves are replaced with newer high capacity ones,” the official added.

Water supply in New Town and Rajarhat however will remain unaffected.
