A Smart System Combining Rainwater and Treated Sewage for Use in Sports Complexes in Korea

Abstract:

Existing systems that provide an alternative water supply such as a sewage reuse system (SRS) or a rainwater harvesting system (RWHS) tend to experience a slight loss of efficiency through the separate use of their component systems. A smart system has been introduced that combines the stable water quality of an RWHS and the stable water quantity of an SRS for use in sports complexes in Korea, and selected monitoring results are presented here in terms of the quantity of water used. The system monitors the operating conditions and provides measurement data. It is designed to be remotely operated at each facility in which it is installed. Ninety-eight percent of the treated sewage was used for lawn watering and maintenance of wetlands. The rainwater collection efficiency was higher in summer than winter in the rainwater utilization system. The amount of water produced from the sewage reuse system can be reduced during summer and increased during winter when less rainfall is experienced. A system that combines rainwater and treated sewage is expected to reduce the cost and energy use for treating wastewater.
