Storm Sewer Safety Features in Cedar Rapids

Storm Safety Improvements

Clearwell staff designed storm sewer safety features for culverts in Cedar Rapids.  Improvements include a safety apron with a 4:1 slope, replacing the flared end section.  Safety grates are spaced to allow water flow as well as provide a “ladder” if someone is trapped.  Maintenance access pads to allow easy access for debris removal.  Low flows are not restricted as the bottom grate is raised 8 inches from the ground.

Storm Safety Grate

The City of Cedar Rapids has made a number of safety improvements to their existing storm sewer system in the wake of a tragic accident in 2014.  It is the hope that these improvements prevent future accidents, while maintaining the function and capacity of the sewer system.
