Rainwater collection system refers to the entire whole process, rainwater harvesting rainwater collection includes four main aspects: the initial split-flow filtration --- --- --- storage reuse. Completed the four stages, the whole process is a rainwater harvesting, which is the rainwater collection system. Reuse rainwater flow chart Intercepting Sewer pipes -------- -------- -------- rain discard flow filtration device to automatically filter rainwater ------- - rain water storage module -------- -------- water disinfection process flow diagram illustrates the point: the early rain through multi-channel pre-processing link, ensure the quality of the rainwater harvesting. The use of water storage module, effectively ensuring the water quality, but do not take up space, the construction is simple, convenient, more environmentally friendly and safe. By controlling the pump pressure and rain controllers can easily be sent rain water points, while real-time response controller rainwater rainwater reservoir water level situation, in order to reach water points. Significance of rainwater harvesting: You can reach energy saving, environmental protection, reduce emissions rain, so the drought, emergency situations (such as fire) is preferable to have water. Also it can be used in life miscellaneous water, saving water, reducing the cost of water treatment.
