DJB to clean Yamuna before Commonwealth

As part of efforts to spruce up the capital ahead of the 2010 Commonwealth Games, authorities will launch a major clean up of the Yamuna, including a complete overhaul of the city's sewerage system to ensure that no untreated effluents enter the river.

The main problem behind the pollution of Yamuna is the emptying of untreated effluents into the river, Delhi Jal Board CEO Arun Mathur said.

"We have therefore chalked out a plan involving a major overhauling of the city's sewer system which will ensure that no untreated sewage goes into the river," Mathur said.

One of the focus areas of this programme is the installation of systems to intercept sewage on the three major drains of Delhi - the Najafgarh, Shahdara and supplementary drains.

"These three drains carry over 75 per cent of the city's sewage," he said. By putting in place separate intercepting sewage treatment plants in front of these drains, a major part of the untreated effluents can be taken care of.

Apart from this, plans are afoot to augment the capacity of sewage treatment plants attached to the two main drains emptying into the Yamuna at ITO. "Their capacity will be increased from 2 MGD to 10 MDG," he said.

"Following the de-silting, the drains would be connected to the main Okhla treatment plant," Mathur said, adding the basic idea is that no untreated effluent should enter the river.

According to government figures, more than 249 million litres of industrial waste is emptied into the Yamuna in Delhi every day.

The DJB has already filed affidavits with the Supreme Court on its plans. The apex court had given directions to clean up the river.

A detailed opinion on the matter will be sought from various consultant authorities and work would begin within four to five years, Mathur said.

Out of the total 249 million litres a day of industrial waste generated, facilities have been created for treating 156 mld, leaving a gap of 93 mld.

There are 29 planned industrial estates in Delhi covering small and medium scale industries, for which 11 CETPs have been set up to treat waste water.

In towns taken up under the Yamuna Action Plan (YAP), 18 drains in Delhi, nine in Haryana and 74 in Uttar Pradesh are reported to be contributing to pollution in the Yamuna.
