With the Government's ordinance making rainwater harvesting mandatory in buildings, old or new before August 31, Chennaiites can approach several agencies who are involved in installing the structures. Mnadavelipakkam's III Trust Link Street is distinct from others with its model house on RWH called Rain Centre. This 'home', featuring poster panels and providing the venue for screening of RWH films, has a sump, a loft tank for immediate use and an open well for recharging. The Rain Centre became a reality thanks to the combined efforts of the Akash Ganga Trust, Centre for Science and Environment, Chennai Corporation, CMWSSB and the TWAD Board.
