It was shocking to read the report “About 125 tmc ft has washed away in the sea in October and November” (Tamil Nadu, 22 November), given the difficulties faced by Tamil Nadu with respect to water almost throughout the year. The administration needs to act and think in a revolutionary way to handle the issue of water management.
Apart from rainwater harvesting, the state needs to build and rejuvenate several dams and lakes. We spend huge resources to convert sea water into drinking water but it is paradoxical that we allow good fresh water to flow into the sea.
Assessment of available water in shallow and deep aquifers, use of water conservation techniques, redefining norms for recycling and reusing effluents, installation of water meters, ground water drafting, water audit and efficient use of recycled water Measures can be important. ,

I am writing this letter as Ex-Scientist F and Former Officer-in-Charge, ICMR-Vector Control Research Center Field Station. In the context of the report “Dengue cases on the rise in Manipur border town of Moreh” (some editions/online, 22 November), the authorities need to consider: Screening of infected persons from neighboring and other states with testing/ speed up investigation. For IgM or IgG. Care should be taken to ensure that children avoid aedes aegypti Or aedes albopictus Mosquito There is a need to use hand-operated fogging machines in the home of each identified infected person to target adult female mosquitoes hiding in dark places and corners of the bites. More trained people should be deputed to the field. School and college children should also be trained as volunteers.
