The seven lakes that supply drinking water to Mumbai have water stock of 11.06 per cent or 1,60,137 million litres as of the morning of June 7. In the past 24 hours, from 6 am on Friday till 6 am on Saturday, the catchment areas of these lakes have received considerable rainfall, at 174 mm, according to information from Brihanmumbai Municipal Corporation (BMC). In contrast, this area had received merely 18 mm rainfall in the 24 hours between Thursday and Friday morning. Since the onset of the Southwest monsoon on May 25, the catchment areas of these seven lakes has received a total of 415 mm of rainfall.
Mumbai city receives its drinking water supply from Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vehar, and Tulsi lakes, whose total water capacity is 14,47,363 ML. BMC supplies 3950 ML water to Mumbai per day. On the same day last year, the lakes recorded water content at 6.35 per cent, or 91,861 million litres. Two years ago, the lakes recorded water content at 11.14 per cent, or 1,61,297 million litres.
According to information from BMC, every 1% of water from the lakes suffices for water supply for an average of 2.5 to 3 days. With concerns over depleting water levels in these lakes, the BMC had written to the state government in March, requesting water from the Bhatsa and Upper Vaitarna dams to ensure uninterrupted water supply for the city. A senior civic official said, “The rains in the catchment area have been good so far, and there will be no concerns of a shortage of water for the city’s water supply this monsoon.”
