Water woes are unlikely to affect Mumbaiites till July 31 next year. With just a week left for the monsoon to end, water stock at the disposal of the city’s civic body has reached 14.31 lakh million litres, which will be sufficient to cater to the city’s water needs for the next ten months.
Upper Vaitarna, which is the second-largest among the seven lakes that supply water to the city, reached its full capacity on Monday, and is on the verge of crossing the overflow mark.
Upper Vaitarna, which contributes 16.4% of the city’s daily water supply, will be the sixth lake to reach full capacity this monsoon, having done so in a period of seven weeks.
“Although Upper Vaitarna’s water level matches its full supply level, we will not officially consider it to be overflowing till water flows through its gates on to the other side of the dam,” said a senior official of the civic hydraulic engineer’s department.
Bhatsa lake, the largest of all the seven lakes, which contributes 51.6% of the city’s daily supply, is just .26 metres short of reaching its full supply level.
The Brihanmumbai Municipal Corporation (BMC) requires a water stock of 14,47,363 million litres of water by the end of the monsoon. Its current water stock of 14,31,224 is just 16,139 million litres short of this mark.
“By October 1, we need water stock that will last us the next 304 days. As on Tuesday, we have water for 301 days in the Bhatsa supply system and 302 days in the Vaitarna system. So, we have almost received sufficient water stock,” said the official. Worried about the prospect of a water shortage in the face of a delayed monsoon this year, the BMC had imposed city-wide 20% water cuts from July 1 to July 30, which was reduced to 10% and completely lifted on August 14.
