Catch Basins & Storm Inlets in Radnor

Catch basins and storm inlets are drainage structures installed at low points of paved areas to collect surface water runoff. They typically include a grate at the surface and a basin below that traps sediment while allowing water to flow through to the drainage system.

We recommend quarterly inspections and cleaning—with additional maintenance after major storms—to ensure basins remain free of debris, sediment, and blockages that can cause water backup and flooding.

Common signs include standing water around the basin, cracked or broken grates, sunken pavement surrounding the structure, foul odors, or visible structural damage to the basin itself.

Yes, our team can retrofit or completely replace outdated storm inlets with modern, more efficient designs that improve water collection capacity and reduce maintenance requirements.

Properly functioning catch basins prevent water from pooling on and beneath pavement surfaces, which would otherwise lead to erosion of the base materials, accelerate freeze-thaw damage, and cause premature pavement failure.
