The Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) will launch its Dial-a-Green Tanker service on November 1 to supply treated sewage water for construction, industries, landscaping and other non-potable uses, with an initial target of 500 million litres a day.
The initiative is intended to reduce the use of drinking water for activities that do not require potable supplies and protect Hyderabad’s reserves during a period of concern over rainfall, groundwater availability and reservoir levels. HMWSSB Managing Director K Ashok Reddy said the board was preparing the service amid concerns over the impact of El Niño and possible water shortages next summer.
The board has identified construction sites, industrial units, parks, green belts and other users as potential consumers of treated sewage water. The move comes as HMWSSB seeks to conserve potable water during the eight months before the next monsoon, when pressure on the city’s water system could increase.
HMWSSB has held a meeting with representatives of the Confederation of Real Estate Developers’ Associations of India, Telangana Builders’ Forum, National Real Estate Development Council and other construction-sector stakeholders. The discussions focused on increasing the use of treated water in construction and related activities instead of drawing on drinking-water supplies.
A Green Water Tanker digital platform is being developed to support the service. The platform will register treated-water suppliers, tanker operators, construction companies, industries and other users. It is expected to match demand with treated water available at nearby sewage treatment plants, while considering delivery distances and tanker availability.
The proposed system will also enable online bookings and tracking. By connecting users with treatment plants and tanker operators, HMWSSB aims to make treated sewage water more accessible for non-potable applications and improve visibility over deliveries.
The board’s target of 500 MLD represents an effort to build a large-scale reuse network rather than rely only on individual arrangements between treatment plants, tanker suppliers and end users. Its implementation will depend on the availability of treated water, the participation of construction and industrial users, and the functioning of the digital booking and tracking system.
HMWSSB has not announced further operational details in the supplied report, including the service’s tariff structure, the treatment plants that will participate, water-quality standards for different uses or the number of tankers expected to be registered. The board’s next stated milestone is the launch of the Dial-a-Green Tanker service on November 1.
