NEW DELHI: Six new decentralised sewage treatment plants are expected to come up soon with the Delhi Jal Board (DJB) shifting focus from larger plants, which require wastewater to be taken to a far-off plant, to smaller ones in the locality itself.
The DJB has started work on plants at Gautampuri near Aali gaon, Aya Nagar village, Sai Nagar, Kair village, Sonia Vihar A-Block and Begum Vihar B-Block.
50,000 to be benefitted
These pilot projects, which will come up at a cost of Rs.95.32 crore, will benefit about 50,000 people, said officials.
The plants will treat sewage till a level where it can be used for non-drinking purposes like bathing.
The treated water will be supplied through a dual pipe system to be installed in houses.
The project includes a provision for supplying drinking water through a separate pipe.
DJB CEO S.S. Yadav said: “The decentralised approach will help us extend water supply and sewer services to all unauthorised colonies and villages quickly.”
Cost effective
The model is also expected to be more cost-effective and efficient than conventional sewage treatment plants.
At present, piped water has been extended to 1,100 out of the 1,642 unauthorised colonies in Delhi while sewerage services are available in only 210. Extending the network with conventional technology would take 15 years, and an investment of Rs.20,000 crore, whereas the decentralised plants will need less funding.
