New Delhi, Sep 27 (PTI) The Delhi Pollution Control Committee (DPCC) has floated a tender inviting proposals from government institutions for conducting a study on the potential impact of enhancing the capacity of sewage treatment plants on the water quality of the Yamuna river.
The study, according to the DPCC’s call for proposals, will examine how effectively the Delhi Jal Board’s sewage treatment plants (STPs) are functioning with increased capacity and whether this has led to tangible improvements in the river’s pollution levels.
The committee has invited government institutions that specialise in environmental research to submit detailed proposals, including methodologies and estimated costs, within the next 15 days. Proposals are to be sent via email to the DPCC’s member secretary.
The study will also look into whether other pollution sources are affecting the Yamuna’s water quality beyond the capacity of the STPs.
“The purpose of this study is to determine the potential water quality parameters of the Yamuna if all the sewage load is treated,” an official said.
During a board meeting in February, the DPCC had raised concerns about the persistent pollution in the Yamuna despite the city’s STPs reportedly treating 70 per cent of Delhi’s sewage.
At present, Delhi generates 792 million gallons per day (MGD) of sewage while its STPs have a capacity of 712 MGD. However, only 550-600 MGD of sewage is treated, according to officials. PTI NSM DIV DIV
