Thumbe dam has water only for 18 days

Mangaluru city is now likely to head towards water scarcity, if the catchment areas of river Nethravathi fail to receive rainfall in the next couple of days.

The city is dependent on Thumbe vented dam constructed across river Nethravathi for its water needs and the water storage level at the dam is decreasing alarmingly. With the inflow of water reaching zero-level, the level of water storage stood at 7.9 feet in the 13-foot high dam on Saturday.

Mayor Harinath, along with other corporators, officials and representatives of industries, visited the Thumbe vented dam and reviewed the water-level in the dam.

Speaking to mediapersons, the mayor called upon the citizens of Mangaluru to use water judiciously. He said that water storage at the Thumbe vented dam was enough for only 18 days’ supply. “The water from AMR Hydro Power Project dam will be sufficient for an additional four to five days. The MCC has already initiated measures to supply water to the citizens on alternate days,” the mayor assured.

He said that farmers will be persuaded not to use the pump sets upstream. “A team, led by executive engineer Linge Gowda, has been constituted, and a drive will be started to check the use of pump sets. The team will ensure that water is not wasted. The Corporation has already stopped supplying water to construction sites. Water should not be sprinkled on the road to check dust,” he insisted.

The Mayor said that if there was any problem of shortage of water or case of water being wasted, then the public can contact the executive engineers, assistant executive engineers and junior engineers.

Speaking of supply of water, he said that the number of tankers to supply water to the areas that fail to get water has been increased from three to seven. The houses situated on narrow roads will get water in tankers mounted on three pick-up vehicles. Measures will be taken to supply water through tankers at the areas situated at elevated places, he assured.

“There was deficit in rainfall in Dakshina Kannada in 2015. Its impact is being felt this year. The district normally receives pre monsoon showers in April. This year, however, pre-monsoon shower too has failed. Last year, with the pre-monsoon shower, the water-level at the dam was overflowing on April 25. The water-level at Thumbe vented dam declines by three inches if the water is pumped once to supply to the citizens of Mangaluru,” Harinath explained.

The Mayor said that the MCC has initiated measures to drill six borewells in the areas where there is acute shortage of water. Two borewells have been completed at Vamanjoor and Pacchanady. “If the situation aggravates, then water will be drawn from all private borewells and other water sources within the city limits to supply it to the citizens of Mangaluru. The supply to industries will be stopped fully. In case of necessity, the district administration will be asked to make arrangements to release water from the dams situated at Subramanya, Hosmat and other places,” Mayor said.

The MCC supplies 2 MGD water to gram panchayats that are situated between Thumbe and Padil. The MCC is planning to purify the water to hand it over to the gram panchayats to take over the maintenance of water supply to Adyar, Pudu and Thumbe Gram Panchayats.
