Catch Basin Screen / Filter
Trash Guard Plus is a patented catch basin screen / filter designed to trap and filter solid materials and floatables out of stormwater runoff while maintaining water flow. These devices have been proven through extensive testing and come in three screen sizes for use with discharge pipes with <24” diameter. A calculator to help design professionals select the appropriate screen size is available. Each screen can be adjusted at installation to accommodate low flow stormwater events of 10 cfs or more.
Installation of a Trash Guard Plus screen is relatively straightforward and quick with no heavy equipment required. As with any catch basin filter, regularly scheduled maintenance to reduce clogging or flooding is necessary. With the Trash Guard Plus, it is recommended that these units be inspected and cleaned every 3 months (or after any major weather event).
- Made from 100% HDPE
- Optional bottom plate available for rounded bottoms
- Optional retaining rails available for plate removal
- Simple retrofits to existing catch basin- Installs easily without heavy equipment
- Adjusts to irregular catch basin bottoms and/or walls
- Helps eliminate stormwater trash at public parks, beaches, and within the waterways
How the Trash Guard Plus works:
Sizing the Unit:
Before installing the device, a hydraulic calculation should be performed to determine maximum flow rate based on depth of the catch basin and size of Trash Guard Plus used. This calculated model will determine maximum flow rate with no obstructions or varying amounts of trash build up, and determine the drainage area required to support the calculated flow rate. Allowable trash build up and drainage area required for trash build up will determine maintenance frequency. Every 3 months is recommended at minimum, with additional cleanings after major weather events.
If catch basin conditions allow an increased flow rate and additional vertical capacity is desired, a model can be calculated to determine flow rate when extending Trash Guard Plus from 1” – 7” from the catch basin wall. As above, this calculated model will determine maximum flow rate with no obstructions or varying amounts of trash build up.
