Hyderabad’s Green Water service will begin on November 1, with the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) supplying treated sewage water for construction, industrial, gardening and other non-drinking uses. The initiative will initially operate with 21 board-arranged tankers drawing water from sewage treatment plants (STPs) across the city.
The service is designed to divert treated wastewater towards activities that do not require drinking water. HMWSSB officials said the supplies would be used for construction work, park maintenance, gardening and other non-potable requirements.
The first phase includes five tankers operating from Attapur, three from Amberpet, and two each from Mir Alam, Nagole, Mulkatva Cheruvu, Nalla Cheruvu, Hussain Sagar and Saroornagar. One tanker each has been listed at Kokapet, Gopanpally and Lingamkunta. The board said the service would later be expanded to all divisions in phases.
About 100 private water tankers have registered with the HMWSSB for the initiative, according to officials. Supplies through the private tankers will also be expanded in phases as the system is extended beyond the initial network.
The tankers will be painted green, carry prescribed branding and display the warning, “STP Treated Water – Not for Drinking.” The identification requirement is intended to distinguish the treated sewage water from drinking-water supplies and communicate its restricted use to customers and the public.
The HMWSSB has appointed special officers at each participating STP to supervise filling points, tanker allocation, water quality and supply operations. These officers will oversee the service as the board begins coordinating treated-water distribution across the participating treatment plants.
The launch places wastewater reuse within Hyderabad’s broader urban water-supply operations by creating a dedicated distribution system for non-potable demand. The board’s next step is to commence the tanker service on November 1 and expand its coverage in stages, including to additional divisions and registered private tankers.
