Inlets are precast concrete structures designed to capture surface water through grates or curb openings and direct it into the stormwater drainage system. By intercepting runoff from streets, parking lots, and landscaped areas, inlets help control surface flows and reduce water accumulation. Built to meet AASHTO and ASTM standards, our inlets deliver dependable performance, long service life, and are available in round, square, and rectangular configurations to meet a wide range of project requirements.
