CHENNAI: After the success of rainwater harvesting technique, Tamil Nadu government is planning to put to use the excess rain water let out in the storm water drains by linking it to water bodies.
Chennai Corporation sources told Express that a consultant is now preparing a detailed project report so that the storm water drains are linked into reservoir.
Interestingly, the state is also planning to recharge the groundwater and Chennai Corporation has mapped the water stagnant areas during the monsoon.
“We are looking at how the water can be utilized for ground water recharge,” the sources added.
Meanwhile, Chennai Metro Water managing direct B Chandra Mohan while speaking at a second regional dialogue of 15th Delhi Sustainable Development Summit said that the special grade water treatment plant in Perungudi to supply water for construction activities will be ready in next few weeks.
The plant, built at a cost of Rs 56.6 lakh, would produce six lakh litres of special grade water per day for construction purposes. “The water supplied from the plant will help reduce the stress on ground water resources being used for construction purposes. On an average the city requires 20 lakh litres of water for construction purposes,” he said.
Chandra Mohan said that while the Centre has mandated reuse of 10 per cent of waste water, the state has already pioneered the waste water technology and has even made a policy decision to supply treated re-used water for industry purposes.
He said industries in the Chennai-Bangalore Industrial Corridor would be provided with treated water only.
He expressed concern over the failure of monsoons and said the reservoirs are 15 to 20 per cent dry due to lack of rains in catchment areas. He said the state is now banking on waste water reuse, rain water harvesting and desalination plants.
