The Delhi Government is getting Asia’s largest wastewater treatment plant built in Okhla, where 564 MLD of sewage can be treated daily. The project is in its final phase. Delhi Water Minister Atishi inspected this plant on Thursday and found that the project was behind schedule. The minister pulled up officials for delay and gave them a deadline to start the STP by the end of this year.
Emphasising on the significance of the project in clearing the Yamuna, Atishi said any delay in the construction of the treatment plant "will not be tolerated." "Expedite the remaining project work by making timelines, and submitting progress reports every Monday. Any delay in their construction would not be tolerated," Atishi said.
The Delhi government is getting Asia's largest wastewater treatment plant built in Okhla, where 564 minimal liquid discharge (MLD) sewage can be treated daily and the project is in its final phase, according to the officials.
The Water minister further said cleaning the Yamuna is the priority of the Kejriwal government and that officials are working round the clock to ensure the same. "Once operational, the Okhla STP will be Asia's largest wastewater plant - capable of single-handedly treating nearly 20 per cent of Delhi's sewage!" Atishi wrote on social media platform 'X'.
She said the Delhi Jal Board has been instructed to submit project status reports to her every week to ensure that no deadlines are missed to commission the project. The STP at Okhla will treat wastewater from most parts of Central and South Delhi and after purifying, the treated water will be discharged into the Yamuna.
The officials said sewage from most parts of Central Delhi (mainly in the NDMC area) and South Delhi will be directed to the Okhla plant, a move that is expected to benefit 40 lakh people in the city. This plant is the largest wastewater treatment plant in Asia, which alone will treat 15 to 20 per cent of Delhi’s sewage. After treatment, the water’s Biochemical Oxygen Demand (BOD) will reach a level where it can be used for various purposes, including gardening.
Using the biogas derived from sewage sludge, the plant can generate 4.8 megawatts of electricity. Additionally, the waste-to-energy plant can be operated using the sludge, and it can also be utilized for gardening and other purposes.
