Another 11 people were injured when the 300ft (90m) dump partially collapsed on Friday as Sri Lankans celebrated their traditional new year.
“We are still carrying out clearing operations,” said military spokesman Roshan Seneviratne.
“The final death toll is 32 and a handful of people who were listed as missing are now accounted for.”
Hundreds of security forces have been working round the clock to clear the debris at Kolonnawa on the northeastern edge of Colombo.
Authorities have declared neighbouring areas unsafe for housing. Yesterday, Prime Minister Ranil Wickremesinghe promised survivors permanent housing within a couple of months.
He also promised to shift the garbage dump and move the residents to safer locations.
Parliament had earlier been warned that the vast tip posed a serious health hazard, and that a long-term solution was needed to dispose of Colombo’s trash.
A night of heavy rain, followed by an outbreak of fire, destabilised the 23mn-tonne garbage heap at Kolonnawa, causing its collapse.
Garbage has been piling up since Friday in the capital, home to 700,000 people, after the dump was shut down.
The Colombo Municipal Council had promised to remove the rotting piles of rubbish along the streets by noon yesterday, but residents said it remained uncleared.
There were sporadic protests in the suburbs of Colombo against the dumping of garbage in smaller landfills in their neighbourhoods.
Police were called to disperse protesters along a main highway yesterday and allow garbage trucks access to new dumping grounds.
