The government has taken a big step to control the pollution of Yamuna river in Delhi. Now real-time monitoring of Yamuna water quality will be done on the lines of Air Quality Index (AQI). For this, 41 online monitoring stations will be established. According to officials, these stations will continuously monitor the pollution level of water in Yamuna River and the drains falling into it. With this, the pollution situation can be assessed immediately and necessary action can be taken in time.

The government has set a target to make all these stations live by June 2026. Through these monitoring stations, a total of 11 types of pollution parameters along with the flow of Yamuna water will be examined. With this, it will be possible to find out which place has more pollution and what is its source.

Target to make all stations live by June 2026

According to a senior DPCC official, 6 of these stations will be installed directly on the Yamuna River between Palla to Okhla Barrage, to monitor the quality of the main flow of the river. At the same time, the remaining 35 monitoring stations will be installed on the major drains falling into Yamuna. These include major pollution sources like Najafgarh Drain, Shahdara Drain, Barapula Drain. A large amount of dirty water and industrial waste falls into Yamuna from these drains, hence monitoring here will help in identifying the real sources of pollution.

Now it will be done using modern technology instead of the traditional method. Till now, to check water quality, one has to rely on sampling based system, which causes delay in action. Delhi Pollution Control Committee (DPCC) takes 8 samples every month from different places of Yamuna, these samples are sent to the lab and tested, the entire process takes about a week. Due to delay in receiving reports, immediate action is not possible. Real-time level of pollution is not known. Many times information is available only after the situation worsens. After installation of 41 real-time monitoring stations proposed by the government, immediate information about the pollution level will be available. This will help the officials in taking immediate action. Yamuna cleaning campaign will get data based strength.

Main source of pollution in Yamuna

Only 22 kilometers of Yamuna River flowing in Delhi falls in the capital, which is only 2 percent of its total length. But the surprising thing is that 76 percent of the total pollution load falls on this area. According to experts, the biggest reason behind this heavy pollution is the dirty water falling from the drains. Najafgarh drain alone is responsible for about 70 percent pollution. About 16 percent pollution comes from Shahdara drain. In view of this serious situation, the government is now going to install online monitoring stations on Yamuna river and the drains falling into it.
