Display Field: FACILITYID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The feature is a point shapefile that has six subtypes to classify data; air release, combination, flushing connection, terminal flushing, simple check and vacuum release. An air release is used for odor control, with the added benefit of preventing corrosion in the manhole or vault from di-hydrogen sulfate gas. A combination is two or more subtypes that are conjoined. The most common combination is a combination flushing and air/vacuum release valve manhole. A flushing connection is in the connection between the remote seal flange and the piping flange in which the flushing ring is used to clean and drain the remote seals when it is required. Terminal flushing are mechanisms that are installed in manholes, primarily at the upstream terminal ends of sewage main to facilitate the periodic flushing of the downstream mains. A simple check is a clapper which hangs from a hinge, the clapper shaft or pin, which is mounted to the underside of the bonnet, inside the valve body is designed to allow fluid to flow one way in a pipeline and inhibits backflow within the line. A vacuum release uses differential pressure between atmospheric pressure and the partial vacuum pressure maintained in the piping network and vacuum station collection vessel.
