Delhi Drones: Delhi Municipality to deploy drones to inspect landfills

The Municipal Corporation of Delhi (MCD) has decided to deploy drones to map the elevation of the landfills and also monitor the reduction in its height along with other parameters, officials said on Saturday.

The national capital has three landfills – Ghazipur, Bhalaswa and Okhla – which have turned into huge mountains of rubbish.

A plan in this regard has been prepared and the project will soon be implemented, they said.

They said the drone survey report would also be sent regularly to the lieutenant governor’s office.

The move comes about a fortnight after LG Vinai Kumar Saxena visited the Ghazipur landfill site and asked MCD officials to submit a progress report on their plan to raze these landfill sites.

Following LG’s instructions, the civic body last week presented an update on efforts to reduce the height of landfills.

The MCD listed steps such as bioextraction of legacy waste and setting up waste-to-energy plants to flatten and close landfills in its landfill status report.

Frequent fires at landfills on the capital’s borders have also left people living near mountains of rubbish breathless.

A senior MCD official said the municipality is using all the tools to level the landfill and effectively monitor the execution of the work.

“In our latest initiative, a plan has been prepared to deploy drones to measure the height of the three garbage piles across the city and also monitor their height reduction along with other parameters. exact idea of ​​the dimensions of the landfills and the rate at which their height is decreasing thanks to a number of efforts,” the official told PTI on condition of anonymity.

He said a similar pilot exercise was carried out a few months ago with good results.

The official explained that the height and other dimensions of the three burial sites will first be measured using drones and after every 2-3 months their dimensions will be studied again, which will reveal the exact deduction height of dump sites.

City officials have said the deadline for leveling the Ghazipur landfill is December 2024, while efforts are underway to raze the Bhalaswa landfill site by July next year. The Okhla landfill is expected to be razed by December 2023.

In 2019, the height of the Ghazipur landfill was 65 meters, only eight meters less than the height of Qutub Minar.

In 2017, part of the Ghazipur landfill fell on an adjacent road in which two people were killed.

Another MCD official said proper photography and videography of these burial sites will be carried out during the survey using drones.

“The project is being taken care of on a priority basis and will be executed soon. A report regarding the monitoring and the measures taken to level the landfills will also be sent regularly to the LG office,” the official said.

According to municipal authorities, the city cumulatively generates about 11,400 metric tons of waste, of which nearly 6,200 metric tons are dumped in these three landfills.

The remaining 5,200 tonnes of waste is processed locally using compactors and waste-to-energy (WTE) plants.

According to city officials, in total nearly 250 lakh tons of legacy waste is in the three landfills that need to be treated.

The MCD has deployed trommel machines at the three landfills for bio-extraction or processing of old waste.

It is also setting up WTE plants to boost waste treatment capacity. The municipality has also endeavored to encourage the sorting and treatment of waste at source.
