Delhi Spent Rs 55 Billion On Yamuna Clean-Up In Three Years

03 Dec 2025 CW Team

According to the Delhi Jal Board (DJB), expenditure on efforts to keep the Yamuna clean over the past three financial years totalled about Rs 55.36 billion.

The Yamuna enters the National Capital Territory of Delhi at Palla village, where its water quality is monitored by the Central Pollution Control Board through the Delhi Pollution Control Committee. Water quality at this point varies throughout the year depending on water availability and catchment discharge.

CPCB reported median Biochemical Oxygen Demand (BOD) and Dissolved Oxygen (DO) levels of 4 mg/l and 6 mg/l respectively between January and July 2025. However, the DPCC’s September 2025 monitoring results showed improved levels, with BOD at 2.5 mg/l and DO at 9.5 mg/l — both within the healthy river criteria of BOD below 3 mg/l and DO above 5 mg/l.

Major causes of pollution in the Yamuna in Delhi include: • Discharge of untreated or partially treated sewage; the treatment gap in August 2025 stood at 414 MLD. • Absence of Common Effluent Treatment Plants in some approved industrial zones. • Delays in completing new sewage treatment projects and in rehabilitating or upgrading existing facilities.

DPCC also reported that Delhi generates 11,862 tonnes of solid waste per day, while existing facilities can treat 7,641 tonnes per day, leaving a gap of 4,221 tonnes per day.

The National Mission for Clean Ganga supports States in curbing pollution in the Yamuna by extending financial assistance to Himachal Pradesh, Haryana, Delhi and Uttar Pradesh. Under the Namami Gange Programme, 35 projects have been sanctioned for the Yamuna’s rejuvenation at an estimated cost of Rs 65.34 billion. These projects aim to create 2,243 MLD of sewage treatment capacity, of which 21 have been completed.

The information was provided by the Minister of State for Jal Shakti, Shri Raj Bhushan Choudhary, in a written reply in the Rajya Sabha.
