DJB setting up 5 water treatment plants for non-potable purposes

The Delhi Jal Board is setting up five decentralised Waste Water Treatment Plants (WWTP) to treat effluent for non-potable purposes and bridge the demand and supply gap.

According to a DJB official, a decentralised WWTP has been set up at Keshopur with a treatment capacity of 66KL/day. “Trial run of the plant has been successful. Sewage at the plant is being treated at the tertiary level and the water samples, lifted during the trial run conform to the drinking water standards as per the WHO norms,” said the official. The DJB is setting up another decentralised WWTP at Varunalaya Phase I, its headquarters at Jhandewalan, with the technical support of the Centre for Science and Environment (CSE). The construction of the plant is in progress. The effluent treated will be used for horticultural purposes. The CSE will also be assisting the DJB in setting up another WWTP at Balmiki Colony, near Chandrawal Water Works.

Officials said another one MLD capacity WWTP will be set up at Zaffepur and Mitraon (Najafgarh), with the assistance of the NEERI. The effluent treated will be used for non-domestic purposes and for recharging water bodies in the village. Recharging of water bodies will help improve the groundwater , another official said.

“The process of setting up a decentralised WWTP at Aaya Nagar, with the technical support of the NGO, FORCE, is in progress. The effluent treated will be used for non-domestic purposes in the area as well as for recharging water bodies. Upon the commissioning of the WWTP, groundwater from the land around the water body can be extracted and supplied to villages to meet their water demands,” a DJB spokesperson said.
