In a major push towards sustainable water management, the Goa government has announced that treated water from nine sewage treatment plants (STPs) will now be made available free of cost for non-potable purposes. This initiative aims to ease the pressure on freshwater resources while encouraging environmentally responsible practices across construction, agriculture, and urban maintenance sectors.
According to a recent public notice issued by the Finance Department, the state’s treated wastewater is now accessible to the public, commercial entities, and industries for activities such as concrete curing, dust suppression, soil compaction, road construction, and gardening. The scheme is expected to meet up to 50% of the current demand for non-potable water within a 15-kilometre radius of each operational STP.
The nine facilities covered under this initiative include Calangute-Baga (5.6 million litres per day), Patto-Panaji (2 MLD), Sankhali (0.8 MLD), two units at Shirvodem-Margao (4.20 and 6.7 MLD), Katem-Baina Vasco (6.20 MLD), Durbhat (1 MLD), Colva (7.50 MLD), and Kavlem-Ponda (15 MLD). These plants collectively produce a substantial quantity of treated effluent, which until recently remained underutilised or released into nearby water bodies.
As per the guidelines, those wishing to collect treated water must arrange for their own dedicated tankers, which must follow prescribed colour-coding norms. The vehicles must not be used for carrying potable water or sewage to avoid contamination risks. Necessary pumping systems will be installed at each STP to facilitate water collection.
Urban planning experts believe that this initiative can pave the way for improved climate resilience. Cities that reuse wastewater for non-drinking purposes reduce both environmental pollution and dependency on freshwater sources. Moreover, by integrating treated water into construction and public sanitation, the state moves closer to achieving its sustainability goals without compromising on infrastructure growth.
While the water is offered free of cost, timely logistics, monitoring, and awareness are critical to ensure both safety and uptake. As Goa balances its tourism economy with sustainable development, the availability of free treated water for urban and industrial needs represents a practical, climate-resilient solution.
