Let's first introduce this intelligent rainwater and sewage diversion well. It is applied in urban drainage networks, especially at the end or main nodes of combined sewer networks, and is a core intelligent facility used to achieve accurate rainwater and sewage diversion and control of overflow pollution. Moreover, the intelligent diversion well marks a profound transformation in urban drainage management from "coarse diversion" to "precise regulation" of water flow. 

Performance advantage comparison: Advantages of traditional interception wells: Long construction period for civil engineering, low automation level, requiring manual descent into the well for dredging, high risks; unable to achieve accurate flow limitation and interception ratios. Advantages of the integrated system: Zero direct discharge of sewage on sunny days, zero backflow of river water on rainy days; active interception, intelligent flow limitation; automatic discharge in heavy rain, preventing backflow of sewage and pollutant discharge into the river; equipment is configured with remote monitoring via cloud platform; combining gravity flow and pressure boosting. 

What are the application scenarios? For example, the construction of new, renovated or expanded combined sewer drainage systems within cities; for old urban areas or urban villages that do not have the conditions for rainwater and sewage separation renovation; as well as municipal pipeline projects, rainwater and sewage separation projects, sponge city construction, and black and odorous water body governance, etc. 

Application Case: The xx Industrial Park in Emei Mountain, Sichuan Province purchased a set of 304 stainless steel interception wells. After installation, it significantly reduced the risk of overflow pollution during moderate to heavy rain. Since then, the surrounding environment of the street has improved, no unpleasant odors have appeared in the residential area, and even the municipal government has praised it in the market. 

In conclusion, the intelligent rainwater and sewage interception well, with its precise intelligent control, effective construction and operation maintenance mode, as well as unique system performance, is gradually replacing the traditional interception well. Moreover, this rainwater and sewage interception well has gradually become one of the main technical equipment for improving the quality and efficiency of urban sewage treatment, controlling non-point source pollution, and building a smart drainage system.
