Product Information

GrateGator is an innovative “above the grate” stormwater filter. Its design removes sediment and debris as it enters the catch basin. Manufactured with a durable, high-flow multi-dimensional filter, it offers superior flow rates. GrateGator also has built-in overflow protection. It filters out contaminants while allowing bypass during heavy rain or extreme weather.

With its reusable design, you can clean and reuse GrateGator for the life of a project.
