MCCARTHY TYPE INLET WITH
STARTER SECTION FOR FLUME

McCarthy type flume inlets are designed to collect and discharge roadway runoff into down-slope flume in order to prevent erosion on steep slopes. This product results from a collaborative design effort between Pacific Corrugated Pipe Company and national forest service engineers. It has since been adopted for use in the Angeles and San Bernardino National Forests and in many other areas with similar needs.
