By starting a process of scientific closure of
accumulated municipal solid waste, the Coimbatore Corporation sought to
provide on Thursday a sign of relief for residents in more than 15
colonies around its compost yard at Vellalore.
These
colonies had been exposed to health hazards for close to a decade
because of flies from the dump yard and smoke from burning garbage
invading their houses.
The Rs. 12.56 crore scientific
closure or capping that began on Thursday is one of the components of
the Corporation’s Rs. 96.5 crore Integrated Municipal Solid Waste
Management Project. This is being implemented under the Jawaharlal Nehru
National Urban Renewal Mission. The other methods of waste disposal at
the yard are turning bio-degradable garbage into manure and burying deep
the non-biodegradable ones in landfills. As for the colonies that
formed the Kurichi-Vellalore Pollution Prevention Action Committee
(KVPPAC) to demand the shifting of the yard, the relief will not come
immediately. It will take four months for the Corporation and the
private party it has tied up with to complete the capping.
Totally,
8.86 tonnes of garbage lies accumulated across the 300-acre yard.
Officials explained that the immediate task was to bring all these waste
to a 17-acre site earmarked for the closure. This work alone would take
one to one-and-a-half months.
While landfill involved digging a vast, deep pit, the capping would be just the opposite.
Waste
would be piled up in two blocks, of a height of nearly 25 ft each.
These will be compacted to eliminate any loose portions from coming off.
A 200 mm layer of gravel would be laid on these and over this a 600 mm
layer of clay to prevent water from seeping in. Another topping of 150
mm gravel would be provided and then a layer of non-woven geo-textile.
Finally, a 300 mm natural soil would form the topmost layer, in order to
create a green space.
When fully capped, the two
sections would resemble inverted boats. Rain falling on these would flow
down the slopes into a drainage that would be provided around the
17-acre site.
The Corporation said it would strain
every sinew to make up for lost time. Commissioner T.K. Ponnuswamy
ordered that more workers, vehicles, and equipment should be put into
this work so that there would not be any further loss of time.
The
closure project was originally planned for garbage yards at
Kavundampalayam, Ondipudur and Vellalore. The work had been completed in
the first two sites.
The work in Vellalore ran into
ligitation. The residents’ committee moved the High Court in 2004 for an
order that no waste management project should come up at this yard.
The
court directed the Tamil Nadu Pollution Control Board to hear both
sides (the residents and the Corporation) and dispose of the case. After
the hearing, the board gave the clearance in March 2011. By then 5.5
lakh tonnes of additional garbage had accumulated, over the 3.36 lakh
tonnes that was estimated to be capped in 2008. The litigation had
stopped the process of turning waste into manure. This, in turn, led to
the accumulation of the waste in the open yard.
Alive
to the resentment among the residents, the officials said that
hereafter the waste brought to the yard every day would be disposed of
the same day through landfill, recycling or composting (turning into
manure).
Secretary of the action committee K.S. Mohan
was sceptical of the efficacy of the project. “Actually, we are certain
that our problem will not be solved with whatever the Corporation does
now. The threat of pollution will be eliminated only if the scheme is
shifted out of this yard.”
