DEVELOPMENT OF RAINWATER RECLAMATION SYSTEM WITH WATER CIRCULATION : Evaluation of water purification performance of a pilot plant

Abstract

The authors developed a pilot plant of rainwater reclamation system consisted of a under ground reservoir, filter stratum of sand and rainwater catching greenbelt of lawn. Porous concrete blocks and effective materials for the water purification are placed in the reservoir. Rainfall on the greenbelt is stored through the filter stratum in the reservoir. The rainwater is circulated to the filter stratum. This paper deals with the evaluation of performance of the pilot plant. It is evident from the inspection data that the developed system keeps good quality of the rainwater for long periods.
