County Materials manufactures a comprehensive range of precast Wet Utility Structures, including inlets, catch basins, manholes, and junction boxes, all designed for dependable performance in stormwater and municipal infrastructure. These structures meet strict AASHTO and ASTM specifications and are built to withstand harsh environments while delivering a long service life. They are available in round, square, and rectangular configurations—ranging from 24″ to 144″ inside diameters—to meet diverse project requirements.
Inlets feature durable grated or curb-opening designs that efficiently capture runoff from streets, parking lots, and landscaped areas, while catch basins include sump areas that trap debris and sediment, reducing downstream clogging and enhancing system performance. Inlets are precast structures that capture surface water through grates or curb openings and direct it into the stormwater drainage system. They intercept runoff from streets, parking lots, and landscaped areas, helping manage surface flows.
