Jal Board ready with 2 plants at Games Village

The Delhi Jal Board (DJB) has commissioned two state-of-the-art plants: the 1 MGD sewage treatment plant (STP) and 1 MGD water treatment plant (WTP) at the Commonwealth Games Village. The plants will be inaugurated by Chief Minister Sheila Dikshit on Saturday.

The construction of the 1 MGD WTP was awarded to M/S VA Tech WABAG Ltd on October 13, 2008, at a cost of Rs 35 crore. The scope of the WTP included treatment of groundwater from underground deep bores using technologies such as hardness, ammonia and nitrates removal, filtration and disinfection.

The plant includes a clear water reservoir and a pump house, rejuvenation of existing borewells, raw water supply lines, alternate arrangement for source of water supply, a boundary wall, landscaping, and electricity arrangements with alternative sources.

“The WTP also has a connection from the 140 MGD Sonia Vihar WTP to act as a standby source whenever the quantity and quality of groundwater is not up to the mark,” a senior DJB official said.

The sewerage facilities at the Games’ village are being provided by the Delhi Development Authority. To minimise pressure of drinking water supply by DJB, the STP would be a zero-discharge plant, and there will be 100 per cent recycling of waste water for flushing toilets, air conditioning, and maintaining horticulture at the Games’ complex.

“The 1 MGD state-of-the-art STP, which has been developed using membrane technology for treatment and reclamation of waste water is the first experiment in Delhi, which would see 100 per cent utilisation of sewage for non-potable purposes,” DJB CEO Ramesh Negi said.
