Making large campuses resilient to heavy rain

‘RWH structure should be installed based on soil profile’

With the intense spell of rain like the one witnessed in November likely to become a frequent phenomenon owing to climate change, experts stressed on the need to make large open spaces more resilient to floods.

Shilesh Hariharan, principal architect at Madras Terrace, who is associated with the City of Thousand Tanks initiative, said installation and strengthening of rainwater harvesting and recharge wells must be done based on soil profile on campuses.

He said it was important to identify the region of clay, the region of sand and so on to make the percolation of water efficient. Regular maintenance of rainwater harvesting structures prior to monsoons was important.
