Mumbai’s water network to grow to 100 km with new 9.7 km tunnel; similar to NYC’s 111 km System

In a ground-breaking development, Mumbai is set to revolutionise its water supply system with a 9.7 km-long underwater tunnel. This engineering feat, part of the Brihanmumbai Municipal Corporation's ambitious 100 km water tunnel network, will serve as a crucial lifeline for the densely populated areas of Ghatkopar, Parel, and Wadala.

This project was initiated in October 2021 to address issues of water contamination, leakages, and insufficient water pressure in these densely populated areas.

Constructed at depths of up to 100 meters, the tunnel promises to eliminate contamination risks and reduce man-made leakages that have long plagued the city's aging pipeline system. With diameters ranging from 2 to 5 meters, these subterranean channels will deliver water with unprecedented force and efficiency.

The project, initiated in October 2021 and costing ₹940 crore, faced numerous challenges, including the COVID-19 pandemic. However, it persevered, achieving key milestones in September 2022 and June 2023.

Upon completion in 2026, this tunnel will elevate Mumbai's underground water network to 100 km, second only to New York's 111 km system. As the city takes a giant leap towards modernising its water infrastructure, residents can look forward to a more reliable and robust water supply in the coming years.
