New Delhi: Yamuna could not be fit to take a shower in the absence of a minimum environmental stream in the river, the Delhi government said in a report delivered in the Ministry of Jal Shakti.
It was also said about 35 waste treatment plants in Delhi, 22 did not meet the standard of waste water prescribed by the Delhi pollution control committee (DPCC).
Of the 13 general waste treatment plants in industrial estates throughout Delhi, only six adhere to the DPCC standard for wastewater.
“The minimum environmental stream for polluted water dilution in Yamuna in Delhi is needed to meet the level of quality of water desired in the river for the purpose of bathing i.e.
BOD5 mg / l,” read report.
According to the International Union for nature conservation, environmental flow is water provided in rivers, wetlands or coastal zones to maintain ecosystems and benefits where there is competing water use and where the flow is regulated.
A study conducted by the National Hydrology Institute, Roorkee, has recommended that water 23 cubic meters per second (CUMEC) was released in the river of a series of Hathnikund in Yamuna Nagar Haryana Regency in the lean season to maintain the downstream ecosystem.
“The ministry / national mission for clean ganga has observed that the 1994 water sharing agreement among Riparian Uttarakhand, Himachal Pradesh, Uttar Pradesh, Haryana, Rajasthan and Delhi will only be revised in 2025, unless there is a need, implying that No revised water sharing will be possible to achieve electronic flow in Yamuna, “read a report of the city government.
“In the absence of a Yamuna minimum environment in Delhi, it is very difficult to reach the quality of bathing,” he said.
22 km from Yamuna from Wazirabad to Okhla in Delhi, which is less than two percent of the river length, accounts for around 80 percent of the pollution load on the river.
There are 18 main waterways, including Shahdara, Najafgarh and Barapulah, which became defecating on the river.
Unprocessed wastewater and poor quality from the effluent released from CETPS and waste treatment plants are the main reason behind pollution in the river in Delhi, according to experts.
The DPCC also told the ministry that the 35 waste treatment plants in Delhi, 22 did not meet the standard of wastewater prescribed in connection with dissolved dense total, demand for chemical oxygen, biological oxygen demand, dissolved amonist nitrogen.
Amisonal nitrogen and phosphate in wastewater must be less than 5 mg / L and 2 mg / l.
According to the Norm of the DPCC, TSS must be less than 10 milligrams per liter, the directors must be less than 10 mg / L and the cod must be below 50 mg / l.
In the inspection conducted in June, 34 of 35 STP found operational.
Samples can be collected from 33 stps.
Of these, 11 was found to comply with the standards determined by the DPCC.
Inspections cannot be made in April and maybe because of Covid’s pandemic, the DPCC said.
Delhi produces around 720 million gallons a day of waste treated at 35 stps has a cumulative care capacity of 597 mgd.
About 86 percent of treatment capacity is being used today, according to government data.
It was also said about 13 Cetps in Delhi, seven did not meet effluent standards.
This CETPS is in the Narina Industrial Area, Lawrence Road, Nangloi, Wazirpur, Mangolpuri, Mayapuri and Jhengil.
Earlier this month, the DPCC has imposed a fine of more than Rs 12 Crore in 12 plant general waste treatment (CETPS) which operates throughout the capital because it does not meet the wastewater standard of prescribed waste.
There are 24 industrial areas in the capital 17 connected to 13 CETPS which treat waste water from industrial units before they can be reused or disposed of to Yamuna.
