Rooftop Rainwater Harvesting to empower individual home owners

BANGALORE: As India continues to witness challenges pertaining to water conservation, corporates and citizens need to step forward to usher in a sustainable and independent approach to saving water. Rooftop Rainwater Harvesting (RRWH) is one such solution that empowers individual home owners to conserve water for consumption through the year.

" Ambuja Cement has decided to champion the cause of Water Harvesting by introducing consultancy and installation rainwater harvesting services as an extension of its technical services," said the company.

Customers can avail of Ambuja’s Innovative Roof Rainwater Harvesting System which is installed once the roof of their bungalow is completed. Interestingly, a meagre 100 cm rainfall annually on a 1000 square feet roof can provide a full year’s supply of water for drinking and cooking purposes for a family of five.

According to the company, Ambuja has developed its Roof Rainwater Harvesting technology through multiple reference codes, manuals and research reports. The rainwater is first collected through channel pipes or gutters made up of PVC or similar materials. A water filter is installed to remove all impurities present in the water collected. The filtered rain water is then stored in a storage tank which can be used for drinking and cooking purposes. The surplus water from the storage tank is discharged into a pit for ground water recharge. The average cost of installing the Roof Water Harvesting system in an individual house which includes plumbing, filter, storage tank and percolation pit installation is around Rs. 40,000
