b'STORMWATERCATALOGCATCH BASINSRainwater surface drainage is typically performed by catch basins, sometimes referred to as inlets. The catch basin is a belowground box structure with a horizontal opening at ground level, where a perforated grate is placed to allow rainwater to enter the catch basin box. The grate is made of a material that best fits the intended use of the surface level. For example, a parking lot would require a cast iron grate that is rated for vehicular weight and for pedestrian areas, a light-duty grate would be used. During a rain event, stormwater drains from the surface area into the grate opening of the catch basin. This water then drains into a sewer pipe that leads from the catch basin box structure. The stormwater sewer piping is placed at a downward-sloping gradient to encourage water to flow through the piping; thisModel GIS-01is known as gravity-flow. Catch basins are linked to pipes creating a network of drainage points.APPLICATIONSThe catch basin is a utility product which is an initial component in stormwater applications. It is also known as storm drain inlet or curb inlet. The catch basin is an opening to the storm drain system. It typically includes a grate or curb at street level where stormwater enters the unit and a sump captures sediment, debris, and associated pollutants. Catch basins are important because they prevent storm sewer blockages and minimize the amount of pollutants entering storm sewers.Model CB-01SAFETY END TREATMENTS DRAINAGE Safety end treatment (SET) structures are used along roadways to terminate stormwater piping that is installed under roadways or driveways. The safetyend treatment (SET) prevents soil erosion and helps support the driveway.Driveways that cross an open ditch require SETs. Stormwater piping is placed below roadways or driveways to create a continuous waterway. SETs are normally installed in pairs; at the inlet and the exit of this piping.As an important safety feature, the SET can be equipped with galvanizedsteel rails on top of the structure to provide a safer embankment to deflectan out-of-control oncoming vehicle away from the concrete structure.The SET equipped with rails saves lives. Typically, the county or the state determine the specifications for SET structures. Model SETH-1Optional features for SETs include multiple pipe configurations, transverseor parallel safety rails, trash screens, and flap valves. APPLICATIONSSafety end treatment (SET) products are ideal for applications near roadways or walkways. The unit provides solutions for erosion control and related issues. ParkUSA offers a wide range of configurations and sizes, making SET units suitable for several applications and zone configurations.Model FCS-01INFO@PARKUSA.COM|888-611-7275|WWW.PARKUSA.COM 125'
