Trash Racks & Bar Screens

Industry & Application Experience: Cambridge Water Screen Systems designs and fabricates custom Trash Racks and Bar Screens for cooling or processing water at power plants and industrial facilities, as well as, for stormwater, wastewater treatment and other applications. Our experience includes both new construction and replacement projects, as well as, reverse engineering old systems to repair or replace damaged equipment.

System Design & PE Certification: Our engineers will design custom Trash Racks and Bar Screens to meet a wide range of bar thickness, spacing and project-specific requirements. The final design will receive a PE certification stamp if required. We design our Water Screen Systems per ASD (Allowable Stress Design) specifications. The PE stamp confirms our calculations that the screens and frames can withstand the loading from the forces due to the given flow rate, the dimensions of the water intake opening, and screen clogging percentage.
