The water levels in lakes supplying drinking water to Mumbai have risen following heavy rainfall in their catchment areas. According to Brihanmumbai Municipal Corporation (BMC) data, the combined stock in the seven reservoirs that provide water to the city now stands at 95.12 per cent.
As per the BMC on Wednesday (August 20), the collective water stock in these reservoirs is 13,19,640 million litres, which amounts to 95.12 per cent of their total capacity.
The BMC supplies drinking water daily from Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vihar, and Tulsi lakes.
Of these, Tansa has 100 per cent water stock, Modak Sagar 100 per cent, Middle Vaitarna 98.69 per cent, Upper Vaitarna 91.51 per cent, Bhatsa 93.19 per cent, Vehar 100 per cent and Tulsi 100 per cent.
