Everwise Credit Union P a g e | 5 W240018 STL Inlets Inlet cleaning and repair is usually performed to respond to localized flooding problems in streets, however inspections should be made on a routing basis. Inlets without sumps do not trap sediments and don’t need cleaning unless they are discovered to be plugged. Cleaning of inlets can be done with a shovel, clamshell, shovel, or vacuum truck. Stormwater Conveyance Pipes A good rule of thumb is to inspect pipes by camera at least once every three years, prior to the beginning of the rainy season and early enough that repairs can be made during dry weather. Evidence of pipe distress include excessive silt build-up, erosion, unusual algal growth, cracked or collapsed pipes, misaligned joints, and other signs of problems such as a sheen on the water surface, discolored water, or an unpleasant odor. Check with product manufacturers or storm water handbooks for advice on what to look for when inspecting more sophisticated treatment devices such as flow splitters and diverters. When a problem is noted, take steps to correct the problem, or route this information immediately to the appropriate individual(s) in your organization who can respond. If needed, develop a good response plan to ensure quick follow -up in the future.
