Trash Guard screens can be installed in two hours or less, depending on the installation experience accumulated by public works staffs.

Cleaning cycles for each screen size will vary from site to site depending on Foliage, Grass Cover, Bare Ground Construction Sediment related run-off and the season of the year. At over thirty locations in topography ranging from the mountains to coastal areas the cleaning cycles required have been either Quarterly or Semi-Annual under a variety of rainfall conditions.

The EPA’s Stormwater Menu of BMPs suggest these maintenance considerations for screen inserts:

“Typical maintenance of catch basins includes trash removal if a screen or other debris capturing device is used, and removal of sediment using a vactor truck. Operators need to be properly trained in catch basin maintenance. Maintenance should include keeping a log of the amount of sediment collected and the date of removal. Some cities have incorporated the use of GIS systems to track sediment collection and to optimize future catch basin cleaning efforts.”
