Mumbai: BMC Invites Tenders For ₹2,000 Crore Pise-Panjrapur Water Tunnel To Strengthen City’s Supply

Mumbai, October 29, 2026 - The Brihanmumbai Municipal Corporation (BMC) has released an invitation for tenders to design and build an 8-kilometer raw water conveyance tunnel between Pise and Panjrapur in Thane district. The main objective is to bolster Mumbai's water supply infrastructure by replacing four older pipelines that currently transport water from the Pise pumping station to the Panjrapur water treatment plant.

The chosen contractor will be responsible for securing all required government approvals, permissions, and clearances, including those related to the Coastal Regulation Zone (CRZ), forests, environment, archaeology, and any other applicable statutory or regulatory requirements.

The 72-month contract is estimated to cost around Rs 2,000 crore. The Pise-Panjrapur complex, located in Bhiwandi, Thane district, plays a crucial role in Mumbai's water supply network. Raw water sourced from the Bhatsa River is pumped from Pise to Panjrapur, where it undergoes treatment before being distributed to Mumbai and its surrounding areas. Currently, four pipelines of varying diameters - each ranging from 2,235 mm to 3,000 mm - handle water transport along the 8-kilometer stretch.

In September 2026, the state government granted approval for the conveyance tunnel project, following a March 2026 initiative by the BMC. This approval mandates the BMC to conduct a thorough geological survey prior to selecting a tunnel boring machine (TBM) and ensuring excavation does not harm any structures along the route. The BMC's chief official stated that the underground tunnel would safeguard the water supply against external pollution and unauthorized extraction, decrease losses from aging and leaky channels, and maintain uninterrupted water supply to the Panjrapur Water Treatment Plant during monsoons and emergencies.

Additionally, the BMC plans to increase the water treatment capacity at the Panjrapur plant from 1,365 million liters per day (MLD) to 1,820 MLD. This will be achieved by replacing an existing 455-MLD plant with a larger 910-MLD facility.
