Delhi Chief Minister Arvind Kejriwal on Thursday announced Delhi Govt's six-point action plan designed to clean the Yamuna river in order to restore bathing standards by February 2025.
According to CM Arvind Kejriwal, the waste water from four major drains falling in the Yamuna including those from Najafgarh, Badshahpur, Supplementary and Ghazipur, is being treated in-situ.
Delhi Chief Minister Arvind Kejriwal on Thursday announced Delhi Govt's six-point action plan designed to clean the Yamuna river in order to restore bathing standards by February 2025.
According to the chief minister, 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 our sewage treatment capacity from around 600 million gallons of waste water a day to 750-800 MGD," Kejriwal said.
He said the waste water from four major drains falling in the Yamuna including Najafgarh, Badshahpur, Supplementary and Ghazipur, is being treated in-situ.
The government will shut down the industries discharging industrial waste into the Yamuna, the Aam Aadmi Party (AAP) leader said.
Waste water in "jhuggi jhopri" clusters flows through storm water drains into the Yamuna. These clusters will be connected to the sewer network, the chief minister said.
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.
"Our engineers and officers are hopeful that we will be able to clean the Yamuna by February 2025 with the implementation of the six-point action plan.
"Specific targets have been set for each action point and I will personally monitor the progress," Kejriwal said.
Delhi generates around 720 million gallons of waste water a day. The 35 STPs at 20 locations across the city can treat up to 597 MGD of sewage and have been utilising around 90 per cent of their capacity.
Pictures and videos showing devotees offering prayers in the Yamuna on the occasion of Chhath Puja with foam floating on the surface of the river have triggered a political slugfest between the ruling AAP and the Bharatiya Janata Party (BJP) in Delhi.
The 22-kilometre stretch of the Yamuna between Wazirabad and Okhla, which is less than two per cent of the river's length of 1,370 kilometres from Yamunotri to Allahabad, accounts for around 80 per cent of the pollution load in it.
According to experts, the primary reason behind the formation of foam in the Yamuna is a high phosphate content in the detergents used in dyeing industries, dhobi ghats and households in Delhi, Haryana and Uttar Pradesh.
The poor quality of effluent discharged from common effluent treatment plants (CETPs) and STPs is another reason.
Waste water from authorised colonies and settlements containing a high phosphate content reaches the river through untapped drains. When the water falls from a height at a barrage, the turbulence agitates the phosphoric compounds in the river, which leads to the formation of froth.
Frothing in certain stretches of the river, such as near ITO and the Okhla Barrage, has become an annual phenomenon now in winters when the temperatures are low and the flow in the river is less.
