South corporation finally stops dumping at saturated Okhla landfill

Of the 3,500 tonnes of waste collected from south Delhi everyday, the civic agency dumped around 1,200 tonnes at the Okhla landfill. The site was declared as exhausted way back in 2010.

Eight years after the Okhla landfill exhausted its life span, the South Delhi Municipal Corporation stopped dumping garbage there last month.

Of the 3,500 tonnes of waste collected from south Delhi everyday, the civic agency dumped around 1,200 tonnes at the Okhla landfill. The site was declared as exhausted way back in 2010.

Corporation  officials said the waste is now being dumped at a nearby 14.2-acre plot transferred from the Cement Corporation of India (CCI) in 2016-17.

“We took the decision to avoid a repeat of last year’s cave-in at Ghazipur. The site was established in 1996 and its height continued to rise because of the huge volume of unprocessed municipal solid waste,” Kamaljeet Sehrawat, SDMC mayor, said.

At 55 metres, its height is almost thrice the permissible limit, a south Delhi MCD official said.

The civic agency now aims to complete the remediation of the Okhla landfill within one-and-a-half years to convert it into a green cover. “We have already started work to stabilise the slope in the Okhla landfill in consultation with a retired professor from Indian Institute of Technology (IIT). The exercise will be completed till August, when the chances of cave-in are high,” Sehrawat said.

Puneet Goel, commissioner, SDMC, said, “We will reduce the size of the landfill by half after it is closed. It will be capped scientifically by using a certain quantity of waste.”

For the collection of leachate (the liquid that comes out from a landfill) and methane gas emitted during the breakdown of organic matter at landfill, SDMC plans to insert pipes at various locations.

Dumping will continue at the14.2-acre plot until SDMC constructs its engineered landfill at Tehkand.

The civic body targets to complete the project in the next 18 months. “The Tehkhand landfill will be operational by next year-end. The 37-acre land was allocated by the Delhi Development Authority (DDA) to SDMC in 2016 and the civic agency also plans to develop a waste-to-energy plant here,” said SDMC official.

North Corporation’s plan

The North Delhi Municipal Corporation has also issued a tender for hiring a consultant to submit a study on remediation of the Bhalswa landfill. “We are closely monitoring day-to-day activities, but a decision has been taken to hire a consultant who would suggest stabilisation measures for the landfill,” North Corporation official said.
