Connector Pipe Screen (CPS) Unit Specs & Drawings

Listed within the Full Trash Capture Certification Program by both the Los Angeles and the San Francisco Bay Regional Water Quality Control Boards, our Connector Pipe Screen (CPS) has become the BMP of choice for cities as they strive to meet rigorous storm water regulations. This metal screen assembly is installed inside a catch basin, in front of the outlet pipe, for preventing debris from entering the storm drain system. A CPS unit is designed to retain all trash and gross solids larger than 5 mm (0.197 in) inside the catch basin (e.g. cigarette buds), and once in place it also retains large volumes of sediment as well. Therefore, the trash capture and storage capacity of this product is dependent upon the size of the catch basin where it is to be installed. A CPS unit can be used in conjunction with a curb inlet screen cover and/or DrainPac™ Storm Drain Filter Insert for added effectiveness based on the level of trash and debris that commonly accumulates at the site.

CPS Unit Custom Configurations

Custom configurations are designed as needed for nearly any catch basin scenario (e.g., pipe lines entering from any wall or catch basin floor).
CPS units can be configured to be permanently mounted to the catch basin or to have a quick disconnect feature to facilitate pipe line jetting or to prevent flooding should the basin drainage system become clogged.
Catch basins containing CPS units should be cleaned when the screen is ≤ 40% covered to prevent the possibility of flooding and/or pollutant overflow into lateral pipe lines.

CPS units are custom-designed for every catch basin
