Mumbai's water stock has started showing improvement after continuous spells of heavy rainfall across the city and surrounding regions over the past few days. The seven reservoirs supplying drinking water to Mumbai reached 13.19 per cent of their total useful live storage capacity as of 6 am on Sunday, July 5, according to data released by the Brihanmumbai Municipal Corporation (BMC).
The combined useful live storage across the seven lakes increased to 1,90,898 million litres against the total capacity of 14,47,363 million litres.
However, the current water stock remains lower compared to the same period last year. On the corresponding date in 2025, the lakes had recorded 54.27 per cent storage. In 2024, the water level stood lower at 9.01 per cent.
Officials said the latest spell of rainfall has helped improve the situation, and lake levels are expected to rise further if consistent rain continues in the catchment areas.
The seven lakes that supply water to Mumbai are Bhatsa, Upper Vaitarna, Middle Vaitarna, Tansa, Modak Sagar, Vihar and Tulsi.
Among the reservoirs, Upper Vaitarna recorded a water level of 595.83 metres. Its useful live storage stood at 4.31 per cent.
Bhatsa, which is one of the largest contributors to Mumbai's water supply, recorded improved storage levels, reaching 110.30 million litres, or 9.93 per cent of its capacity.
Middle Vaitarna recorded a level of 247.05 metres, with its useful live storage reaching 16.47 per cent. Tansa Lake stood at 120.31 metres and held 11.07 per cent of its capacity.
Collectively, Upper Vaitarna, Middle Vaitarna and Tansa recorded 13.29 per cent useful live storage.
Most lake catchment areas received significant rainfall over the last 24 hours, contributing to the rise in water levels.
Mumbai had witnessed concerns over water availability in June due to lower reservoir levels. However, the recent spell of heavy rainfall has provided relief, with officials expecting further improvement in the coming days if rainfall activity continues.
Authorities continue to monitor the water stock situation across all seven reservoirs.
Meanwhile, Mumbai and neighbouring regions continued to receive heavy rainfall, with the India Meteorological Department (IMD) keeping a red alert in place for the city on Sunday.
The weather department has forecast continued rainfall activity, with very heavy showers likely at several locations and extremely heavy rainfall expected in isolated areas.
The Brihanmumbai Municipal Corporation has urged citizens to remain cautious and avoid unnecessary travel during periods of intense rainfall.
Several areas across Mumbai recorded more than 200 mm of rainfall in the last 24 hours, while a few locations reported nearly 300 mm. Civic teams remain on alert to respond to any rain-related incidents.
