DPCC to Install 41 Online Stations to Monitor Yamuna Water Quality in Delhi
Real-time tracking of pollutants across rivers and drains for five years….
New Delhi :The Delhi Pollution Control Committee (DPCC) has announced plans to set up 41 online monitoring stations to track the water quality of the Yamuna river and its connected drains. This is an upgrade from the earlier proposal of 32 stations.
What Will Be Monitored
According to the official tender, six river locations, including stretches of the Yamuna and other rivers, will be equipped with advanced monitoring systems to measure key parameters such as:
Flow
pH level
Biological Oxygen Demand (BOD)
Chemical Oxygen Demand (COD)
Total Suspended Solids (TSS)
Total Nitrogen (TN)
Total Phosphorus
Ammonium
Dissolved Oxygen
Temperature
Conductivity
In addition, 35 major drains that discharge directly or indirectly into the Yamuna will also be fitted with Online Monitoring Systems (OLMS). These stations will track flow, pH, BOD, COD, TSS, total organic carbon, and conductivity in real-time.
Why This Project Matters
The decision was taken following a Delhi High Court order on April 8, 2024. It was finalised during the 70th DPCC Board meeting and later reviewed by the Director General of the National Mission for Clean Ganga (NMCG) on July 24, 2025.
The project will include five years of operation and maintenance, ensuring continuous data transmission to the DPCC server. The monitoring will be conducted as per the latest Central Pollution Control Board (CPCB) guidelines and SOPs.
Purpose of the Initiative
Officials said the primary aim is to track pollutants entering the Yamuna in real-time and take timely action to reduce contamination levels in the heavily polluted river.
Earlier, DPCC had planned to install 32 stations, but with the scale of pollution in Delhi’s drains, the number has now been increased to 41 monitoring units.
