The civic body may soon be able to add 40 million litres of water daily (MLD) to its current supply of 3,750 MLD.
The Brihanmumbai Municipal Corporation (BMC) has given a contract worth Rs62 crore for construction of another plant at the Panjrapur water treatment unit near Bhiwandi to recycle water wasted during the purification process. The Panjrapur plant treats water from Bhatsa Lake, during which around 50 MLD is wasted. This (40 MLD) is more than the supply of Tulsi Lake (18 MLD) and close to the supply of Vihar Lake (44 MLD). The work is expected to be completed by the end of October.
The civic body has been looking at alternatives to increase the water supply. “We were to construct the treatment plants to recycle wasted potable water since 2012. The Bhandup treatment plant is adding more than 50 MLD,” said an official from the hydraulic engineering department.
Meanwhile, the city has more than 12.9 lakh million litres of water, which will be sufficient for an average of over 340 days, even though two major lakes – Upper Vaitarna and Bhatsa -- are yet to overflow. The lake levels have been depleting for the past week as the gates of Upper Vaitarna and Bhatsa, which help stock water in catchment areas, were opened.
The two lakes supply nearly 2700 million litres of water daily. The depleting lake levels of these two state government-owned lakes have led to a decrease in the overall quantum of stored water, said civic sources. The useful water content recorded last week was more than 91% of the total water storage capacity (14.47 lakh million litres). The water stock has come down to 89% this week.
Ashok Tawadia, chief engineer of hydraulic department, said, “As we calculate our water distribution from October 1, we plan for 305 days, till July 31. We have a good amount of water stock. With a month of rain to go, we have nothing to worry.”
