1MGD Water Treatment Plant for CWG Village

Even as green lobbyists debate on the depleting groundwater levels in the city, Delhi Jal Board (DJB) chairperson CM Sheila Dikshit on Saturday inaugurated a 1MGD water treatment plant adjacent to the Commonwealth Games Village. Interestingly, raw water for the Water Treatment Plant (WTP) which will cater to the Village residents will be sourced from ranney wells and deep groundwater wells in the Yamuna riverbed.

Confirmed DJB spokesperson, Sanjam Chima, ‘‘The raw water will be sourced from the groundwater in the Yamuna area. The Sonia Vihar plant will be an alternate source, which will be a back-up during the Games.’’ At a time when the government is mulling charging the public for using groundwater as it regulates the extraction, the use of deep borewells and ranney wells for Village residents may raise eyebrows, admit government sources.

On Saturday though, Dikshit preferred to dwell on the technological advantages of the new systems that have been put in the Games Village WTP, as well as a 1MGD sewage water plant that was also inaugurated. While the WTP will provide ‘‘first world’’ quality treated water using the latest UF membrane technology, the STP will have zero discharge of waste water. In other words, not a drop of water except the sludge will be wasted. It will instead be recycled for use within the Village complex.

Said a senior DJB official, ‘‘For the first time, DDA has been persuaded to put in dual pipeline network, so that recycled water can be provided straight to houses for flushing toilets, air-conditioning, and maintaining horticulture at the Games complex. Being 100% automated, the Village STP is the first to be housed inside a building and the biggest to be used using the membrane bio-rector (MBR) technology.

Meanwhile, the WTP will produce potable water meeting WHO and BIS standards, utilizing UV disinfection as it’s a natural and green product. Speaking at the inauguration, Dikshit said, ‘‘To minimize pressure on DJB’s drinking water supply, the treated waste water will be recycled for further use. The Commonwealth Games will be the first Green Games.’’ While the WTP has been built by M/s VA Tech Wabag Ltd, the STP has been built by UEM. The cost of the former is over Rs 35 crore while the latter was constructed at Rs 31.95 crore. Both were built for the upcoming Commonwealth Games in October.

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 plants, incidentally, were running slightly behind schedule, though the Commonwealth Games Village will be handed over to the organizing committee only in August. The Village will host over 8,000 athletes and officials. The Village complex has over 1,000 flats, which will be sold once the Delhi Games 2010 are over, added DDA sources.
