The Government of Maharashtra has commissioned the Gundavali-Bhandup Water Tunnel Project in Mumbai. Under it, two water tunnels of a total length of 15.1 km have been developed at a cost of Rs 28.87 billion. Under Phase I of the project, a 6.8-km long tunnel has been laid from Gundavali to Kapurbavdi. Further, an 8.3-km long tunnel has been laid from Kapurbavdi to the Bhandup Complex under Phase II. These tunnels are expected to supply 4,000 mld of water from the Vaitarna and Tansa lakes to Bhandup for treatment. The tunnels’ capacities include provisions for the existing supply as well as proposed supply in the future from the Gargai and Pinjal dams.
