Layer: Sewer Air Release Valves (ID: 21)

Name: Sewer Air Release Valves

Display Field: GEODBID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: OBJECTID: System-generated unique identifier for each record within the feature classAncillaryRole: Attribute that indicates whether the junction pushes (source) or pulls (sink) flow in a geometric network. Default setting for the GIS Consortium is none. Enabled: Boolean field to indicate whether water is allowed to flow through this featureGEODBID: Three-digit code that assigns editing responsibility to a community in the GIS ConsortiumFEATUREID: GIS-Consortium-generated unique identifier for each record within the feature class. All FEATUREIDs start with the GEODBID of the community that owns the record. DATECREATED: Date/time stamp from the moment the GIS record was createdDATEMODIFIED: Date/time stamp from the last moment the GIS record was changedSOURCE: Organization that provided the data. The GIS Consortium standard is to preface the source with the three-letter municipal code of the community providing the data, followed by a dash. Example: VGV-Public WorksSOURCETYPE: Accuracy context for the recordCOMMUNITYID: Unique identifying code selected by the communitySTRCID: Retired GIS tracking identification number for the featureLEGACYTYPE: Retired GIS tracking code for the featureADMINISTRATIVEAREA: Owner of the area in which the feature is locatedSUBTYPE: Additional designation of the feature. Includes the following: air control: Used with a water system pressure tank for controlling the volume of air in the tankair gap: An unobstructed vertical space between the water outlet and the flood level of a fixture used for backflow preventionair release: Allows the air in the pipe to escape thus preventing damage to pipes and fittingsaltitude: A valve that controls the level of a tank. The valve will remain open while the tank is not full and it closes when the tank reaches maximum levelatmospheric vacuum: A backflow prevention device used to prevent non-potable liquids into the drinking water systembackflow control: Open in the direction of normal flow and closed with the reversal of flow; commonly found near pump stations and reservoirscv combination: A spring loaded check valve that uses pressure to regulate water flow between the inlet and outletdouble check: A type of check valve used to prevent backflow from potentially allowing contaminated water back into water supply linespressure vacuum: A backflow prevention device that opens automatically when water pressure reaches a preset limit to relieve stress on a pipelinereduced pressure backflow: Backflow prevention device used to protect drinking water from contaminationRPZ: Reduced Pressure Valve consists of two independent check valves plumbed in series, with a pressure monitored chamber between. The chamber is maintained at a pressure that is lower than the water supply pressure, but high enough to be useful downstream. The reduced pressure is guaranteed by a differential pressure relief valve, which automatically relieves excess pressure in the chamber by discharging to a drainsimple check: A valve which normally allows fluid to flow through it in only one directionvacuum breaker: Prevent a siphon from allowing a contaminant or pollutant into the potable water system; protection from high/low hazard or toxic substances vacuum release: Designed to relieve excess pressure upstream from the linevacuum valve: Used to control gas flow into a chamber, isolate, vent, provide relief or control conductanceLIFECYCLESTATUS: Current state of the real-world featureWATERTYPE: Designation of water distribution or collection system to which the feature appliesELEVATION: Ground level height of real-world feature; measured in feet above sea levelDEPTH: The distance from the top of the structure to its bottom; measured in feetDIAMETER: width of the real-world feature represented in the feature class; measured in inchesWORKORDERID: Unique work order identifierOPERATIONALAREA: Retired field used to store a description for an operational area designated by a communityLOCATIONDESCRIPTION: Statement illustrating the whereabouts of a featureDESCRIPTION: Statement illustrating the feature/recordOWNERSHIP: Organization with jurisdiction over the real-world feature represented in the feature classMAINTAINED: Organization responsible for the care of the real-world feature represented in the feature classINSTALLDATE: Date of installation for the real-world feature represented in the feature classROTATION: Retired GIS tracking field used to turn the symbol that represents the feature on the map so that it matched how it would look in the real worldFID_SSJUNCTIONANNO_LINE: Unique identifier that can be joined to the FEATUREID field of the ssJunctionAnno_LINE feature class to provide a link between the feature and its labelWEBLINK: URL for a website related to the recordGlobalID: System-generated unique identifier for each record that is required in replicated geodatabasesREPLICAFILTER: Code used to filter data for the creation of custom geodatabasesPRODUCTIONNOTES: Technical notes from GIS personnelREGIONALAGENCYID: Retired field used to store a unique identifier for a regional agency with a relationship to the featureShape: System-generated geometry type of the feature
