June 9: The much awaited Rain Water Harvesting (RWH) theme park, a Rs 2 crore project and the first of its kind in the country, will have 26 real models of RWH on display and will start functioning in two months.

Bangalore Water Supply and Sewerage Board (BWSSB) is setting up the park on 48,000 square feet in Jayanagar fifth block, in association with Karnataka State Science and Technology Council. The purpose is to educate people on RWH which is mandatory in the city for houses on 60/40 sites and also for all new houses on 30/40 sites after the BWSSB (amendment) act 2009, came into effect on August 27, 2009.

The RWH models will provide live demonstrations of various methods of rain harvesting practised across the world. An information centre will be set up to provide brochures, booklets and even telephone numbers of plumbers to assist those planning to implement RWH at their houses, said a BWSSB official.

The ground floor of the information centre will have an exhibition of animated glass models of not just RWH but various other technologies on water treatment including membrane technology for treating waste water. This is intended to promote waste water reuse in the city, the official said. Equipment used for rain water harvesting including pop-up filters will also be on display. The park will have a model of the BWSSB water supply system and a map to show how water is brought to the city and distributed among households.

The the information centre will house a multimedia mini audio visual theatre where movies from across the world which depict rain water harvesting practices and its advantages, will be screened. The auditorium will host talks by experts on rain water harvesting, water conservation.
