Hyderabad’s Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) will launch its Dial-a-Green Tanker service on November 1, allowing construction firms, industries and landscaping users to access treated sewage water for non-potable requirements.
The service is intended to reduce the use of drinking water for construction, parks, green belts and other activities while helping protect the city’s potable water supplies. HMWSSB Managing Director K Ashok Reddy said the board was concerned about reduced rainfall, declining groundwater availability and pressure on reserves in the Singur and Manjira reservoirs.
HMWSSB has initially set a target of increasing daily use of treated water to 500 million litres per day. The treated supply is expected to serve construction sites, industrial users, parks, green belts and other users whose requirements do not involve drinking or domestic consumption.
The board 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 to discuss conservation of potable water. The discussions are focused on reducing drinking-water use during the eight months before the next monsoon.
The proposed service will operate through a digital platform named Green Water Tanker. HMWSSB is developing the platform to register treated-water suppliers, tanker operators, construction companies, industries and other users. It will match demand with treated water available at nearby sewage treatment plants, while considering delivery distances and tanker availability.
The platform is also expected to enable online bookings and tanker tracking. This would create a single system for connecting users with available treated water and arranging deliveries from sewage treatment plants.
The plan comes as HMWSSB assesses the risks posed by rainfall uncertainty and lower groundwater availability. The board has linked the initiative to concerns over water shortages next summer and to the need to conserve supplies held in the Singur and Manjira reservoirs.
For Hyderabad’s construction sector, the service will create a formal channel for sourcing treated sewage water for activities that do not require potable water. The board’s consultations with developer and builder organisations indicate that construction companies are among the intended early users of the system.
HMWSSB’s immediate milestone is the launch of the Dial-a-Green Tanker service on November 1. Its initial operational target is to raise daily treated-water use to 500 MLD across construction, industrial, landscaping and other non-potable applications.
