Mumbai’s drinking water reserves, drawn from seven reservoirs, rise as heavy monsoon rainfall continues over the city and surrounding catchment areas. BMC data cited by multiple outlets show that the combined useful live storage in the seven lakes increases to about halfway of total capacity, crossing the 50% mark on July 18. One report says the seven lakes hold 7,34,891 million litres (ML), or 50.77% of total capacity, after a 0.98% increase over the previous 24 hours. Another outlet reports that by July 12 the total useful live storage is 721,354 ML, or 49.84% of capacity, placing reserves close to 50%. Earlier in the monsoon period, reservoirs were much lower—around 41% on July 8–9—before rainfall led to faster gains over the following days. Several lakes reach higher levels at different times, with Vihar and Tulsi repeatedly reported as at or near full storage during peak wet periods. The BMC continues to track reservoir levels and rainfall patterns, while an ongoing supply management approach (including water cuts earlier) has been described as tied to whether reservoirs overflow and whether rainfall intensity sustains.
