Raising the issue, BJP MLA Suresh Bharadwaj asked the minister during the Question Hour that whether the households without sewerage connection were disposing the sewage in the open.
He said the government must ensure sewerage connections in every house in Shimla so as to avoid outbreak of jaundice and other water-borne diseases in future.
Replying to a question of Bhardwaj, Urban Development minister Sudhir Sharma said that the houses, which are not connected to any sewer line, have their own septic tanks and the government would try to connect more houses with the line.
The government would look into the issue of sewerage tax being charged from the households in water bills, despite having no sewer connectivity, Sharma said.
Shimla is in middle of a jaundice outbreak.
