The initiative seeks to promote water reuse and conserve freshwater. While the Colaba STP produces 10 MLD, only 3 MLD is being utilized, leading to the discharge of treated water into the sea due to low demand.

The sale will be formalized through agreements with buyers. The civic body faces challenges in demand and infrastructure, as the cost of potable water remains low in Mumbai.
