The pumps will be used when water-level in the KRS drops below 70 ft

Even as the authorities here are focussing on getting the emergency pumping station at Hongalli, downstream of Krishnaraja Sagar, ready for operation in anticipation of water scarcity ahead of summer, the seven defunct heavy-duty pumps being repaired at the station are likely to be ready by January-end for emergency operations.

The pumps will be operated when the water-level in the KRS plummets below 70 feet. With the water-level at KRS, a major source of drinking water for Mysore, Mandya and Bangalore, depleting, the Mysore City Corporation (MCC) has hired services of electrical engineers to repair the pumps which had been lying unused since 10 years.

The pumps were last operated in 2003 to tide over acute water crisis then. Water from the river-bed was pumped to meet the city’s drinking water requirements. The seven pumps are capable of pumping nearly 50 MLD (million litres per day).

Though the authorities here are allaying fears of a crisis coming summer, since Cauvery water could be pumped from the river-bed to meet the demand and ruled out rationing of water for the time being, they have been advising residents not to waste water and requesting them to use the resource judiciously.

Sources here said recently that the trial run of the pumps would be done once the overhauling was completed. When the pumps are ready for operation, the pumping would be taken up on trial basis to check their usability.

“Perhaps, by January-end, the emergency pumping station would be ready. The pumps can be operated as and when required,” they added.

As part of the proposed plan, the MCC authorities were also examining whether there was a need for hiring more tankers for distributing water in summer.

There are about 20 tankers under MCC for emergency distribution.

“The city requires at least two tmcft of water until June this year for catering to the drinking water needs. A request has been made to the Water Resources Department to set aside the water,” they add.

Meanwhile, drawing water from nearly 93 borewells for daily distribution had been stopped ever since the localities started getting water from Kabini river under the Kabini drinking water project.

The trial-run of the project was done in November last and 12 municipal wards were getting 30 MLD daily since December last. “The Kabini has come to the rescue of the distribution authorities,” the sources add.

Last summer, 30 new borewells had been drilled. But, the water yield was not very encouraging and moreover borewells had to be drilled deeper to source water. Borewells have to be drilled to a depth of over 400–450 ft in Mysore. Despite this, the yield was uncertain, indicating the depleting levels of groundwater.

“As of now, there are no plans to sink new borewells. The total yield from borewells was around 5 MLD. Areas such as Ramakrishna Nagar and Vivekananda Nagar which were getting groundwater all these years were being supplied with surface water because of the Kabini. Hence, no new borewells were being recommended,” the sources add.

In case of emergency, flushing and deepening of existing borewells would be taken up only if necessary in the coming months. Some parts of the localities in the MCC limits and areas under the Mysore Urban Development Authority still get water supply from borewells.
