Hyderabad: The process of capping of the legacy dump at Jawaharnagar landfill site received a boost with 75 per cent of the works related to covering the dump yard with a layer of soil in the first phase getting completed while the remaining works are expected to be completed by this month end.
The site is spread over 4.4 lakh square meters of which almost 3.4 lakh square metres has been covered with a layer of soil with a thickness of 150 millimetres in the first phase of capping.
Minister for Municipal Administration and Urban Development (MA&UD), KT Rama Rao has directed the executing agency Hyderabad Integrated Solid Waste Management to complete the capping works by February 2019.
As part of this process, so far, 4,98,255 cubic tonne of earth or soil has been moved from nearby lakes by employing 22 excavators, three bulldozers and four compactors. The 339-acre landfill, which is in use since 1994, now has 12 million tonnes of waste piled-up, causing a lot of environmental implications.
According to Principal Secretary, MA&UD, Arvind Kumar, already, the first layer of capping is showing results, as the ever-present odour in the environs of Jawaharnagar has come down drastically.
Capping to be completed in six phases:
The GHMC officials in a press release said the entire process of capping has been planned according to international standards and norms and would be completed in six phases.
Initially, the entire dumping yard will be covered by a layer of earth or soil. To ensure that the noxious gases are dissipated properly, officials will be using 300 millimetres diameter pipelines and bore wells dug up to 20 meters depth. Following this, the capping process involves a Geo-synthetic clay layer, an HDPE liner layer, a geo-composite layer to drain rainwater downstream and one more soil layer of about 1.5 feet thickness and finally the vegetative layer.
Big relief to local residents
Before the Minister decided to push for capping of the landfill site, the residents here had on a number of occasions complained about groundwater pollution and air pollution and many even launched agitations demanding stoppage of the operations at Jawaharnagar.
