Catchments such as catch basins, manholes, and curb inlets are underground devices installed and used as receiving inlets with a slotted or solid cover. Curb inlets are visible in the side walls of a basin. Surface water is collected through these devices. Pipes and conveyance structures may connect to catchments to convey water downstream and prevent flooding. Both active and inactive features are contained by this feature class.
