Giving some much needed relief to citizens, the Brihanmumbai Municipal Corporation (BMC) has started supplying full capacity water from the Middle Vaitarna dam.
The dam has an optimum annual storage capacity of 1.93 lakh million litres and will supply at 455 million litres daily (MLD) rate to the city. Until last year, the corporation would supply 273 million litres per day.
Given the scanty rainfall until the end of July this year, the corporation had decided to increase the supply made from the dam in phases, and had planned to achieve the rate of 455 MLD by the end of the on-going fiscal. The increase in supply comes in the wake of adequate rainfall.
"We wanted to see how city's water distribution system stabilises after we start increasing supply. So far, we have found no problem with the system. Hence, we have started supplying full quota water from the reservoir," a senior official from hydraulic engineer's department said.
The useful content from the newest BMC dam is first flowed via natural tract to Modak Sagar lake, located in a relatively low terrain area. The quota received form Modak Sagar is then supplied to Mumbai after being filtered at BMC's Bhandup water complex.
The corporation fetches 2,100 million litres from Bhatsa reservoir. Modak Sagar and Tansa each supply 455 MLD water. The corporation draws 635 MLD, 110 MLD and 18 MLD from Upper Vaitarna, Vihar and Tulsi dams, respectively.
Meanwhile, civic officials said the corporation has received the state government's approval to set up a 15 MW hydro power project on the footstep of Middle Vaitarna dam. "We are now awaiting environmental clearance from the Centre, and are hopeful of getting it soon," the officer added.
