The Puducherry government has no option other than to set up desalination plants to meet the demand for water in the Union territory of Puducherry in the future, said chief minister V Narayanasamy.

Replying to a query raised by a member in the legislative assembly on Wednesday, Narayanasamy said the government will seek financial assistance from a French agency to execute projects including desalination plants to meet the growing drinking water needs of the residents.

He said the government has proposed to make rainwater harvesting structures mandatory in every household in the territory.
