A high-level committee headed by the Lieutenant Governor of Delhi has been set up to overcome the delay in construction of sewage treatment plants (STPs) and decentralized sewage treatment plants (DSTPs). This committee will solve the ground problems for STP and DSTP. The Government of Delhi has submitted a report to the NGT on this.
This high level committee has formed a committee chaired by the Divisional Commissioner, Department of Revenue. It includes the Chief Secretary (Forest and Environment) Department, Vice Chairman of DDA, Chief Executive Officer of Delhi Jal Board. It solves all land related issues. The Delhi government plans to build 40 decentralized STPs, including 14 in Najafgarh.
These will increase sewage treatment capacity by 92 million gallons per day. Lack of land has delayed the construction of 12 STPs for the past seven years, sending wastewater from unauthorized colonies and rural areas directly to Yamuna. At the same time, land is also needed for the construction of a new STP of 10 MGD. Delhi produces an average of 768 million liters of sewage per day.
Delhi currently has 35 STPs with a capacity to handle 632 MGD. These STPs only operate at 69% of their installed capacity. Due to this, only 530 MGD is treated. The government plans to increase Delhi’s sewage treatment capacity to 727 MGD by June and 814 MGD by December this year.
