‘Eco-Friendly’ Spray To Prevent Yamuna Frothing During Chhath | Delhi News

New Delhi: To prevent the ugly pollution froth on the Yamuna at Kalindi Kunj when devotees gather there for Chhath puja, the river will be sprayed with an anti-surfactant. The National Mission for Clean Ganga (NMCG) has constituted a six-member committee to oversee froth control measures.
According to NMCG, members of the Upper Yamuna River Board, UP irrigation department, Delhi Jal Board, Delhi irrigation and flood control department and Delhi Pollution Control Committee have been included in the special committee to formulate ways to control froth downstream of the Okhla barrage at the time of the Chhath puja.
“It has been decided that an eco-friendly anti-surfactant will be sprayed on the surface of the river till Chhath puja. Boat-mounted sprayers will be employed for the purpose,” said an NMCG official. “Other measures to control the froth formation include operating the barrage gate in a manner that avoids free fall of water at the barrage.”
Every year during this season, the Kalindi Kunj stretch of the river witnesses frothing on the surface and the photographs of devotees conducting rituals while standing waist-deep in froth causes a political stir across the nation.
Over the years, the authorities have struggled to manage the froth. Among the range of factors leading to froth formation, officials said, was the release of water from the barrage from a height that resulted in bubbles. There is also a concern that small scale industries and clothes laundering was introducing detergents into the river, causing the formation of harmful froth.
The main aim of the special committee will be to coordinate the efforts of the stakeholders, monitor the efficient use of sewage treatment plants, operate the barrage and spray anti-surfactant on the river. “In view of the festive season, it was felt that coordination was needed on the efforts being undertaken by different departments and agencies to try and contain the problem of froth in river Yamuna downstream of Okhla barrage,” said G Asok Kumar, director general, NMCG.
These steps will be in addition to the sewerage interventions and the monitoring of discharge of industrial effluents under the Namami Gange programme. Last year also, DJB had taken similar measures of spraying fresh water on the froth to flatten it.
NMCG is also working on three main sewage treatment plants on the Yamuna, all of which have a completion deadline of December this year. These are located at Rithala, Kondli and Okhla. The one at Okhla will be Asia’s biggest STP. After the completion of these projects, there will be a considerable improvement in the quality of the Yamuna water because NMCG expects around 1,300 million litres per day of wastewater to stop flowing into the river.
