Mumbai’s drinking water reserves have been greatly enhanced; according to data supplied by the Brihanmumbai Municipal Corporation (BMC), the combined stock in the city’s seven lakes has increased to 77.62% of their total live storage capacity.
Following extensive rainfall in catchment areas, the city’s reservoirs saw a dramatic 7.88 percentage point increase in 24 hours between 6:00 a.m. on July 23 and 6:00 a.m. on July 24. With a combined capacity of 14,47,363 million liters, the seven lakes, Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vihar, and Tulsi, now contain 11,23,443 million liters.
