A STUDY OF RAINWATER HARVESTING SYSTEMS INSTALLATIONS AT THREE RESIDENTIAL HOUSES IN MALAYSIA

The sustainable practice of Rainwater harvesting in urban residential area is rarely encountered in Malaysia. This paper describes and reviews the Rainwater Harvesting Systems installed in 3Nos. residential houses in Bukit Rimau(Shah Alam), Sungai Buloh and Putrajaya, which are located within the urbanized Klang Valley in Malaysia. The installed components of the RWH systems consisting of the capture surface, conveyance systems, screening, storage and delivery systems at each location are described. A study of the potential rainwater capture, water demand and the efficiency of each system are discussed. The rainwater consumed at the installations is compared to the total water consumed at the premise. Recommendations to encourage increase in RWH practices are discussed for successful implementation of RWH projects for residential units in Malaysia
