Hyderabad: It had started off well, and seemed to be headed for a smooth finish. But somewhere in between, the enthusiasm appears to have fizzled out. The capping works at the Jawaharnagar dump yard, which had drawn a lot of attention since it was one of the largest such projects taken up by any municipal body in the country, appear to have got stuck on a slow moving note.

The Greater Hyderabad Municipal Corporation (GHMC), which was asked by the State government to complete the work by April 2019, has missed the deadline.

The works are still on, with officials saying that efforts are being made to complete works before the onset of the monsoon.

GHMC had commenced the capping works at the dump yard in March last year and completed the first layer of soil capping covering 130 acres in June.

The first layer was completed with a one-foot thick soil capping on the accumulated garbage site, spread over 330 acres. Nearly 4.5 lakh tonnes of soil was used to cover the garbage with a single layer.

With rains lashing the city, green nets were laid on the soil layer to arrest erosion due to water flow downstream. The idea was to minimise the soil erosion and seepage of water beneath into the garbage dump.

After first layer, a geosynthetic clay layer, an HDPE liner layer, a geocomposite layer to drain rainwater downstream, a geotextile layer, one more soil layer of about 1.5 feet thickness and finally the vegetative layers is to be laid.

At present, works pertaining to the second, third and fourth layer capping works are in progress. Nearly, 55 per cent of these works are done, the top layers works are also in progress and about 20 per cent works are completed, said an official.

There was a delay in arrival of a few materials, including liner layers from abroad, hence the works are bit behind schedule. Vegetation on the top layer will take time. Protective layer (sixth layer) to arrest at the seepage of water beneath will be covered before the monsoon, he said.
In tune with the capping works, digging of vents to facilitate exhaustion of gases that have accumulated in the heap over the years is also in progress.

The vents are being dug up to nearly 20 feet deep into the piled up garbage to facilitate a provision for the gases to escape. After conducting a survey, officials had identified the need to dig nearly 150 gas vents. Of these, over 100 gas extraction holes have been dug up, he added.

Waste-to-energy plant to come up in a month

In addition to capping works, the Greater Hyderabad Municipal Corporation (GHMC) is also intensifying measures to commence operations at the 20-MW solid waste-to-energy generation plant at the dump yard in a month.

Since the capping works are being taken up in 130 acres, the rest of the space is being used for dumping and processing the freshly brought waste.

After segregation, compost is being generated besides Refuse Derived Fuel (RDF). Of the waste, nearly 40 per cent is used for generating RDF, which is produced from various types of wastes, including municipal solid waste. About 20 per cent is used for generating compost and the rest goes for scientific landfill.

Every day, nearly 350 tonnes of compost and about 2,000 tonnes of RDF are generated at the plant in the yard. The 19.8 MW waste-to-energy plant is expected to be launched in a month and the RDF will be utilised to generate power.
