How much waste water being reused in Delhi?

The Delhi Jal Board (DJB) produces about 100 million gallons per day (MGD), which is 18% of the 528 MGD of treated sewage water through its sewage treatment plants (STP). The treated water is mainly supplied for horticultural and bus washing purposes.

The Indian Express quoted Delhi Jal Board officials as saying that, to increase the amount of water that can be reused, a parallel network is needed to carry treated water to areas like agricultural land on the outskirts of the city. where it can be used.

The demand for treated water for horticulture purposes is high in the area under New Delhi Municipal Council (NDMC). Large plantations in the NDMC area have decentralized sewage treatment plants (STPs) that supply water to them.

According to an official of the Horticulture Department of NDMC, the total capacity of the STP is around 27 lakh liters per day. For example, the 100-acre Lodhi Garden draws 5 lakh liters of treated water from the STP, and so does the Nehru Park.

The official further added, “The treated water currently being used is much less than our original requirement of about 8 MGD (million gallons per day) for green areas. Out of this, STPs supply only around 0.5 MGD. -Sometimes manage with water tankers but this is not enough. The cost of bringing the network from DJB’s STP to these areas for the reuse of treated water is high.

The DJB will soon supply treated water to the villages, at a cost. “We have received the consent of some neighbourhood welfare associations and we are working to provide the network to supply the water.”

“Farms in Chattarpur, Kapashera and Bakkarwala will be connected to the grid and are likely to consume around 20 MGD of water,” a DJB official said. For other institutions to extract treated water for reuse, the question will be who will take charge. the cost of the infrastructure for it, the official added.

In an effort to increase water reuse, the Delhi Jal Board (DJB) wastewater treatment capacity will be increased by 57% (326 million gallons per day) by June 2023. The 35 sewage treatment plants at 20 locations in Delhi can treat up to 577 MGD of wastewater and have been using around 90 per cent (514 MGD) of their capacity. Untapped sewage from unlicensed colonies and clusters of jhu-ggi-jhopri, and poor quality of treated sewage that is discharged from sewage treatment plants is the reason behind the pollution in Yamuna River.
