Apr 27, 2017 (LBO) – Rains expected in May and an outbreak of fire still remain as threats to the hundreds of tonnes of rotting garbage piled up near Sri Lanka’s capital, with rehabilitation of the dump now in progress, a minister said.
“What we are doing now is taking measures to control further collapses and stabilization of the dump as a short term solution,” Minister of Megapolis and Western Province Development Champika Ranawaka told reporters Wednesday.
“As reports claim there is no threat of the dump exploding – there is methane but not dangerous levels. It is the high levels of carbon monoxide that we are worried about as this can be a fire hazard. The rains that are expected in May can also destabilize the dump.”
In the next five months we will stabilize the area and only once this is done will we decide on any future plan for the area, he added.
The ministry has listed the following steps as the action plan for the next five months.

The authorities sealed the rubbish mountain on the northeastern edge of Colombo after it collapsed following an accident that killed over 30 people destroying 145 homes nearby in a garbage landslide two weeks ago.
The Colombo Municipal Council sought and got permission last week from a local magistrate to access another tip outside the city limits as crows and stray dogs picked through bags of reeking garbage left on city streets.
Officials said all the displaced people have been given houses and have been relocated to a new area.
Parliament had been warned the vast tip posed a serious health hazard, and that a long-term solution was needed to dispose of Colombo’s trash.
Meanwhile the President last night gazetted waste disposal as an essential service.
