State Bureau, New Delhi. One major cause of pollution in Yamuna are the drains falling into it. To make the river clean, it is necessary to clean the drains falling into it. Among these, many drains including Najafgarh are dumping the filth of neighboring states into Yamuna.
To solve the problem, Delhi Jal Board will study the drains falling into Yamuna throughout the year. According to its report, necessary steps will be taken to clean the river. The 22 km stretch of Yamuna river between Wazirabad and Okhla is the most polluted part of the river. Meanwhile, 75 small and big drains fall into the river.
Almost 70 percent of the maximum pollution in the river comes from Najafgarh drain. Taking the filth of Gurugram, it enters Delhi and joins Yamuna. Similarly, the filth of Ghaziabad is reaching the river through Shahdara drain.
Problems caused by drains coming from neighboring states
This problem is also being caused by many other drains flowing from neighboring states. Big drains like Najafgarh drain, Shahdara drain and supplementary drain as well as drains coming from Haryana and Uttar Pradesh will also be studied throughout the year. These include Mangeshpur drain, Bupania Chudania drain, drain number 6 near Narela border, Alipur Link drain.
Through these drains, the waste from industrial units along with the filth of the cities is also reaching the river. Preparations are underway to install a flow meter to study their water quantity. This will reveal how much dirty water is falling into Yamuna.
Officials said that the tender process for this is going on. Based on the study report, a decision will be taken to build Sewage Treatment Plants (STP) and Decentralized Sewage Treatment Plants (DSTP) as per requirement.
Currently, the process of installing 27 DSTPs on small drains falling into Najafgarh drain has been started. All households are being connected to sewage treatment infrastructure by the Delhi Government to increase the overall sewage treatment capacity of the river. A target has been set to double the treatment capacity in the next three years.
