The BMC will impose a 20% water cut for eight days between August 22 and September 1 as it plans to commission the first phase of the tunnel between Gundavali in Thane and
Bhandup Water Complex. Raw water is brought to Bhandup Complex treatment plant through a network of water mains like Vaitarna, Upper Vaitarna and Tansa. As the pipelines, some of which are over 100 years old, are corroded, the BMC is undertaking works to replace them with tunnels.
