In the central town of Gampola, residents worked to clear the mud and water damage.
“We are getting volunteers from other areas to help with this clean-up,” Muslim cleric Faleeldeen Qadiri told AFP at the Gate Jumma Mosque.
“We have calculated that it takes 10 men a whole day to clean one house,” said a volunteer, who gave his name as Rinas. “No one can do this without help.”
The top official in charge of the recovery, Prabath Chandrakeerthi, Commissioner-General of Essential Services, said authorities were paying 25,000 rupees (US$83) to clean a home, with costs of reconstruction as much as US$6 to 7 billion.
A further 2.5 million rupees is being paid to begin rebuilding destroyed homes. More than 50,000 houses had been damaged as of Friday morning, officials said.
Chandrakeerthi’s office said nearly three-quarters of the electricity supply across the country had been restored, but some parts of the worst-affected Central Province were still without power and telephones.
President Dissanayake declared a state of emergency on Saturday and has vowed to rebuild with international support.
