An underground pipeline on Sardar Patel Marg will carry an unusual substance: 60,000 litres of treated sewage water from a five-star hotel to a city forest.
The Department of Environment and ITC Maurya hotel will utilise the treated waste water from the hotel for creating irrigation facilities at the Central Ridge,one of the oldest sections of the Delhi Ridge,which is slated for massive plantation exercises ahead of the monsoon.
While Delhi has been on a tree-planting spree before the Commonwealth Games,not all saplings have survived. Besides,the intense heat and lack of water also affects the process,said a forest official. Several saplings have died in Garhi Mandu following a ceremonial plantation last year. In extreme heat,even large saplings need to be irrigated,added the official.
As per Urban Development Ministry norms,large establishments in Delhi are required to undertake rainwater harvesting and treat their sewage water. The water then needs to be used for purposes like horticulture,airconditioning and toilet flushing. ITC Maurya recycles 500 kilolitres of water per day.
They did not need so much water for their own use. They were giving some water to NDMC. We thought this would be useful for the Delhi Ridge,where fresh plantations will be undertaken soon, said an official.
Maurya placed a pipe till the hotels entrance and the Forest Department laid another pipe,which will ferry the water to the forest. The pipeline will be inaugurated on Saturday,World Environment Day,by Principal Secretary to Chief Minister PK Tripathi and Environment Secretary Dharmendra.
Inside the Central Ridge,the water will be collected in a lake and pumps will disperse the water.
Last year,we installed a sewage treatment plant. We are recycling 500 kilolitre water per day. The first phase of our project was to use this water for horticulture,the second for our airconditioning,and now we can donate 60,000 litres of water everyday to the Delhi Ridge, said N Ramamoorthy,chief engineer of the hotel.
