Kerala Chief Minister Pinarayi Vijayan in a tweet said that more than 130,000 flood-hit houses had been cleaned, or nearly a third of those affected.
Authorities are also in the process of restoring electricity connections.
People returning to their homes have been told to stay alert as receding waters leave behind a glut of snakes. State authorities and wildlife experts have formed teams to come to the aid of those who have found snakes in their home, according to local media.
With death toll rising daily, Kerala authorities said “due process will be followed to ascertain if all these deaths are flood related”.
A 68-year-old man committed suicide Wednesday after seeing the state of his home at Kothad in Ernakulam district. A 19-year-old boy took his own life earlier in the week because his school certificates were destroyed by the floods, police said.
The government says that more than 10,000 kilometres (6,000 miles) of roads have been destroyed or damaged while a legislator said 50,000 houses had been wiped out.
