The Mumbai Municipal Corporation continues to supply treated drinking water daily; however, the authority has received an increasing number of complaints regarding contaminated water in several areas across the city. During the 2025-26 fiscal year, the corporation recorded 2,687 complaints related to water contamination. The highest volume of these grievances emerged from wards E, D, T, and Cape West, with a significant proportion originating from urban neighborhoods.

Mumbai sources its water from seven reservoirs, transporting it through large primary pipelines. These critical conduits face various challenges, including exposure to soil, silt, humid weather conditions, waste, and chemical contaminants, which accelerate pipeline corrosion. The aging infrastructure and environmental factors contribute to frequent leakages, which are estimated to account for nearly 30 percent of water loss. These leakages often result in the ingress of polluted water into the supply system. Additionally, instances of water theft have been reported.

Ongoing extensive development and redevelopment projects across Mumbai have further strained the water pipeline network. Construction activities have reportedly caused damage to pipelines, leading to increased leakages and compromised water quality. Such factors have intensified public concern and contributed to the rising volume of complaints directed at municipal authorities.

Residents have repeatedly urged the administration to implement permanent, effective solutions to address the water contamination and leakage issues. However, locals allege that despite these demands, the municipal administration has yet to introduce comprehensive and lasting remedial measures. The corporation continues to manage daily water supply operations amid these challenges while responding to public grievances.
