Delhi government is working on a war footing on a six-point action plan to clean the Yamuna by February 2025. There are six specific action points to achieve this.
The government is constructing new sewage treatment plants (STPs) as well as increasing the capacity of the existing ones and upgrading those.
This will increase its sewage treatment capacity from around 600 million gallons of waste water a day to 750-800 MGD.
The waste water from four major drains falling in the Yamuna -- Najafgarh, Badshahpur, Supplementary and Ghazipur -- is being treated in situ.
The city government will shut down the industries discharging industrial waste into the Yamuna.
The waste water in the jhuggi jhopri clusters flows through the storm water drains into the Yamuna. These clusters will be connected to the sewer network.
The government will provide household connections in areas that have a sewer network. Earlier, the consumers had to get the connections themselves.
The city government has also started de-silting and rehabilitation of the sewer network.
The 22 km stretch of the Yamuna between Wazirabad and Okhla, which is less than two per cent of the river's length of 1,370 km from Yamunotri to Allahabad, accounts for around 80 percent of the pollution load in it.
The poor quality of effluent discharged from common effluent treatment plants (CETPs) and STPs is another reason.
