storm drain

storm drainIt is a facility specifically used in urban drainage systems to collect, guide, and discharge rainwater. Its main functions include removing surface water accumulation, collecting natural precipitation, improving drainage efficiency, and discharging rainwater into natural water bodies or storage tanks through municipal pipelines.

working principle

● Drainage stage: during the rainstorm, the rainwater flows into the grate, and the turbine blade rotates at high speed driven by the water flow, throwing the debris to the collection tanks on both sides, while allowing the clean water to be discharged into the underground pipeline quickly through the filter screen.

● Self cleaning stage: When there is no water, the blades reset due to gravity or spring devices to prevent the accumulation of debris; Some models are equipped with ultrasonic vibration modules to enhance the anti blocking ability at low flow rates.

core functionality

Drainage and flood prevention: Quickly drain rainwater from areas such as roads and roofs through wellheads and pipelines to prevent waterlogging. ‌

Rainwater collection: Collecting natural precipitation such as rainwater and snowmelt, and some systems can store or reuse rainwater. ‌

structural characteristics

Usually composed of a manhole cover, wellbore, and water collection outlet, the manhole cover is equipped with gaps or grilles to facilitate the inflow of rainwater. ‌

Separate the design from the sewage well to avoid pipeline blockage and cross contamination. ‌

Application scenarios

Urban roads, squares, green spaces and other areas play a key role, especially in rainstorm or snowmelt season. ‌

In some areas, rainwater resource utilization is achieved by combining infiltration wells or storage tanks. ‌
