ASE integrated prefabricated cutoff well

Product Introduction

　　In combined sewer systems, it is mainly used in old urban areas or villages where rainwater and sewage separation is not feasible and where it is necessary to intercept the discharge of water into water bodies on sunny days. Due to the limited space and complex construction environment in old urban areas, integrated intelligent interception lifting wells, which have the ability to separate rainwater and sewage, are commonly used. Compared with traditional interception wells, this integrated intelligent device has significant advantages.

Product Features

　　■ Sunny Day Interception

　　Gravity flow: Urban sewage flows directly into the sewage pipeline, achieving interception during the dry season.

　　Pressure lift: In areas with high water levels in the sewage network, the sewage is pumped into the sewage pipeline.

　　■ First Flush Interception

　　When the initial rainwater flows into the interception well, the drainage gate closes, preventing the initial rainwater from directly entering the river. When the water level reaches the pump start height, the pump starts and lifts the higher-pollution initial rainwater in the well into the sewage network for interception. As the rainfall continues and the interception well monitors the rising water level and decreasing water pollution, the interception gate gradually closes to limit interception. At the same time, the drainage gate opens to discharge the water.

　　■ Direct Discharge During Rainy Season

　　When the rainfall reaches its peak, the overflow gates can be fully opened, and the interception gate is closed, and the rainwater flows into the natural water body for direct discharge during the rainy season.
