New Delhi: The Delhi government has ramped up sewage treatment capacity by more than 100 million gallons per day (MGD) over the past nine months as part of its intensified efforts to clean the Yamuna, Environment Minister Manjinder Singh Sirsa said on Wednesday.
Sirsa made the statement after Chief Minister Rekha Gupta chaired a high-level meeting to review the city’s water pollution situation.
“Under the leadership of Chief Minister Rekha Gupta and the guidance of Water Minister Parvesh Sahib Singh, the Delhi government has taken strict measures, including strengthening sewage management, to rejuvenate the Yamuna over the past 11 months,” Sirsa said in a post on X.
According to the minister, Delhi’s total sewage treatment capacity increased from 707 MGD in February 2025 to 814 MGD by November. During the same period, upgraded sewage treatment capacity rose sharply from 299 MGD to 735 MGD, ensuring that nearly three times more sewage is now treated under improved standards.
Sirsa said the number of upgraded sewage treatment plants (STPs) has increased from 16 to 28 out of a total of 37 plants. The capacity of 12 newly upgraded STPs has also been enhanced from 329 MGD to 436 MGD.
He added that the upgradation of the remaining STPs will be completed by December 2027, raising their combined capacity from 79 MGD to 135 MGD. Sewer network work for 13 decentralised STPs is scheduled for completion by December 2026.
The minister said Delhi’s water and sewage infrastructure had suffered years of neglect under previous governments, but the current administration is working round the clock to restore the system and meet its commitment to a clean Yamuna.
“These are not just numbers on paper. They are directly linked to the health of Delhi’s residents and future generations. Clean water is not a luxury; it is the right of every Delhiite,” Sirsa said.
