Water scarcity at Thumbe vented dam, supplying water for both drinking purposes and industrial use in city, is grim with only four feet water available for pumping in reality.

The storage at Thumbe on Sunday stood at 7.9 ft against the maximum level of 13 ft.

Lancelot Pinto, chairman, Standing Committee for Town Planning Improvement in the Mangaluru City Corporation, said that only four feet of live storage of water is available for pumping to the city using two pumps for supplying through network of pipelines.

Water cannot be lifted using two pumps, with each lifting 18 MGD (million gallons a day), beyond the four feet level. Once the water-level fell to four feet, water could be lifted up to 3.5 ft level using a pump and not beyond that due to technical reasons and silt accumulated in the dam. Water lifted using one pump would have to be stored either in Bendoor or at Padil for supplying to the city using tankers.

It is because with two pumps, 36 MGD of water could be pumped to the city in 24 hours on alternate days. One pump could lift only 18 MGD water for three or four days.

In addition, the corporation was also feeding water to Mulki and Ullal. It supplied 1.5 MLD (million litres a day) of water to Ullal and 0.8 MLD of water to Mulki on Saturday.

With the vented dam of AMR Hydel Power Project at Shambhoor, on the upstream of Thumbe, having no water, it cannot feed water to the Thumbe dam.

Mr. Pinto said that 30 workers, in three teams, went on clearing the path for the stagnant water on the Netravathi between Thumbe and Shambhoor to flow down to Thumbe dam hoping that it might yield some water.

A bund on the river near a jackwell at Jakribettu was removed on Sunday.

Mayor Harinath still maintained that water would be enough for the next 12 days which officials in private admitted was not enough. Now, the only solution to the scarcity is rain, they said.
