United Storm Water Inc., products

Affixed to the outside of curb inlet openings. Most commonly applied to curved areas (cul-de-sacs, corners) and shallow drains where the mechanisms of the manual retractable or automatic retractable screen (ARS) cover configurations can not be accommodated. May be removed and stored when excessive rain and accumulated debris may cause flooding

Mounted inside curb inlet openings. May be manually retracted inside the curb inlet and locked in the open and closed positions. Does not require removal or storage by maintenance personnel.

The Wing-Gate™ is an automatic retractable curb inlet screen cover (ARS) that prohibits most trash and debris from entering storm drains during the dry season, while opening automatically during specific water flow conditions to prevent street flooding. The device`s screened gate remains in a closed position during the dry season or low water flow, and the retained pollutants can be removed using routine street sweeping. During periods of increased or heavy water flow, the Wing-Gate™ screen will open with the pressure of water on the screen face, allowing water to flow into the catch basin. The device is capable of opening for a calibrated amount of water flow. As a storm subsides the spring-activated screen gate will automatically return to the closed position.
