Mumbai will have sufficient water for the rest of the year if the city continues to receive above 60 per cent rain in the catchment areas of the Upper Vaitarna and Bhatsa lakes,Additional Municipal Commissioner Rajeev Jalota told the general body meeting of Brihanmumbai Municipal Corporation on Monday.

Jalota said as of July 29,Upper Vaitarna has water reserves for 140 days while Bhatsa lake has reserves for 200 days and the cachment areas of these lakes have received 69 and 66 per cent rainfall respectively. “In the next two months up till October 1,if the city continues to receive rainfall at this rate the water demand for the year will be met. The collection of water has also been progressing smoothly in the Middle Vaitarna Dam and it may be ready for use after the rains,” said Jalota,emphasising that Mumbai requires a minimum water stock for 282 days.

He said the engineers of the Water Supply Department had met with the officials of India Meteorological Department and the Indian Institute of Tropical Meteorology,Pune to discuss the cloud seeding method. “In 2009,we tried cloud seeding 160 times in the cachment areas but it was a failure. We have recently met with Israel’s Water Department officials and they will be providing us with technical assistance. Along with the IMD and the Pune meteorology institute we will be having a conference call with the Israelis on Wednesday August 1.”

Jalota said the civic body would also decide on the progression of the 10 per cent water cut currently in force in Mumbai. Taking cognizance of the water pipe leakage in some wards,he said the civic body had begun the tendering process for the procurement of pressure machines to effectively deal with the problem.
