Delhi civic bodies told to save groundwater, use treated water for irrigating parks
Civic bodies in Delhi will now have to maintain its public parks falling within five kilometers of a sewage treatment plant (STP) with treated water rather than the increasingly scarce groundwater.Updated: Mar 13, 2019 01:14 IST
Civic bodies in Delhi will now have to maintain its public parks falling within five kilometers of a sewage treatment plant (STP) with treated water rather than the increasingly scarce groundwater.
The National Green Tribunal (NGT)- appointed Yamuna pollution monitoring committee directed the north, east and south municipal corporations of Delhi (MCDs) to submit action plans on how they will achieve this.
Similar instructions would also be issued to other government wings such as the Indian Railways, Delhi Metro Railway Corporation (DMRC), public works Department (PWD) and transport department, which have been identified as bulk users of ground water.
“Since a pipeline to transport the treated waste water is not available in most places, treated waste water would be transported using tankers to start with, till regular pipelines are laid or conveyance system is put in place,” stated the minutes of the panel’s meeting in February.
For this, the committee has asked the Geospatial Delhi Limited (GSDL) and DJB to map of all the STPs and parks.
While DJB produces around 460 million gallons per day (MGD) of treated water, at least 265 MGD has to be released into the Yamuna as Haryana’s share. The remaining quantity is available for use such as irrigation, horticulture, recharging water bodies among others. “At present only around 90 MGD is being used. This needs to be increased to utilise at least 30% in the short term and at least 50% in the medium term,” the minutes stated.
Presently, most public parks in Delhi maintained by the civic bodies and the DDA use bore wells for horticulture.
“We are using water tankers to fetch treated water from three STPs to water the parks. We want to eliminate the use of tankers completely and build a pipeline network to our roughly 2000 parks. For this, our engineering department has chalked out a plan worth Rs 102 crore and seeking money under the Urban Development Funds (UDF),” said Rajesh Taneja, Director, Horticulture Department, east MCD.
Experts said the shift for non-potable purposes is important because several areas, including the east, north east, north, west and New Delhi districts have been classified as “over-exploited" in a notification issued by the then lieutenant governor (L-G) in 2010.
