A water recycling project that was inaugurated on Monday in Vasant Kunj aims to keep colony parks green without using up fresh ground water. Delhi Chief Minister Sheila Dikshit inaugurated the pilot project to facilitate re-use of kitchen-waste water for horticulture purposes in the colony. The project has been initiated by the Residents’ Welfare Association of Pocket C and supported by Delhi Parks and Garden Society.
Kitchen waste water from flats is being used for the system and through a series of filter screens, settlement tanks and grease taps, impurity is removed from the waste water and it is made fit for horticulture use. Ms. Dikshit stated that 80 per cent of the water that falls on our roads and rooftops is wasted as it flows out through our drains.
To use this water, the RWAs have also used the abandoned tube-well in central park for creating a rainwater harvesting system. The system takes water from the storm water drain running next to the park. The water is cleaned through a settlement tank and a three-stage membrane filter. The clean water then enters the abandoned tube-well and adds to the groundwater reserve in the park.
Ms. Dikshit said that once a large number of RWAs adopt this system, water conservation efforts would gain momentum. She expressed concern over the fast depleting ground water in Delhi.
