The Delhi Jal Board (DJB) is preparing a scheme in consultation with IIT Delhi and the Central Pollution Control Board to use water released from sewage treatment plants to wash Delhi Metro trains and DTC buses, and also in the city’s stadia.
The move follows a recent order by the National Green Tribunal which asked to the DJB to examine “if the discharge of water can be used for Feroz Shah Kotla Stadium and Ambedkar Stadium and washing of Metro and DTC buses”.
“The green panel asked DJB to conduct a study in this regard and find out the best possible way to reuse water generated from the STPs. We have already started work on this scheme,” a senior DJB official told Hindustan Times.
The order was issued while hearing a plea filed by an NGO, Friends, which claimed that the Delhi District Cricket Association was using reverse osmosis-treated water for the upkeep of Feroz Shah Kotla ground.
“Every drop that flows out of DDCA’s taps is RO treated. At a time when many states are facing drought, it’s very disturbing that DDCA is using water in such a manner,” the plea, filed through advocate Sugriva Dubey, said.
The Delhi Water Policy says the city must increase its recycled waste water use to 25% by 2017, 50% by 2022 and at least 80% by 2027. This is to meet its non-drinking requirement and reduce fresh water use. There is miniscule use of cleaned up waste water now. “If waste water is cleaned up at local levels instead of only at big plants more recycling and reuse is possible,” the policy said.
