School premises are getting sanitised using bleaching powder to welcome their students after five weeks. Most city schools are to be reopened from the coming week after a prolonged gap. Even in the worst flood hit areas like Velachery and Pallikaranai, water have been pumped out and the campuses are cleansed to be ready. Some like Ashram Group of Institutions, which were submerged in knee-deep water during the rain, school authorities have cleansed and sanitised the premises by spraying disinfectants.
