Separate rainwater and sewage flow without external power, low-carbon and energy-saving.
Effectively diverting the dry season and initial rainwater to sewage pipelines.
After being treated, the rainfall overflows into the rainwater pipe network or discharge into the river.
After rainfall, the intercepted pollutants are discharged into the sewage pipeline and transported to the sewage treatment plant.
Prevent early rainwater and sewage with high pollution levels from entering natural water bodies and ensure overflow safety.
1. Installed in existing or newly constructed rainwater inspection wells.
2. Use the water level changes in the pipeline network and equipment well chamber to achieve equipment opening and closing.
3. No need for power connection, easy installation, operation and maintenance .
4. Sediments, floating debris, and other pollutants in rainwater are intercepted in the rainwater diversion well through pollution removal equipment such as HydroBoard B and HydroBoard F-I.
5. Can add a check design to avoid situations such as sewage back flow.
