US 2020/0370283 A1 · Engineering system for collecting and utilizing regional rainwater and allocation method

Abstract

An engineering system for collecting and utilizing regional rainwater includes a rainwater collection system, a water quality treatment system, and a control and allocation system. The rainwater collection system includes a rainwater collection ditch for a hardened underlying surface, a barrier and a water storage tank. The water quality treatment system includes a filter system. The control and allocation system includes a water quality monitoring device, a water level monitor, a control gate and a water pump. The filter system is connected to the underlying surface through the rainwater collection ditch, and the filter system is connected to the water storage tank. The control gate is disposed between the filter system and the water storage tank. The water quality monitoring device and the water level monitor are disposed within the water storage tank. The water pump is used to drain water from the water storage tank.
