OBJECTID: System-generated unique identifier for each record within the feature class<\/SPAN><\/P>

Shape: System-generated geometry type of the feature<\/SPAN><\/P>

GlobalID: System-generated unique identifier for each record that is required in replicated geodatabases<\/SPAN><\/P>

GEODBID: Three-digit code that assigns editing responsibility to a community in the GIS Consortium<\/SPAN><\/P>

FEATUREID: 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.<\/SPAN><\/P>

DATECREATED: Date/time stamp from the moment the GIS record was created<\/SPAN><\/P>

DATEMODIFIED: Date/time stamp from the last moment the GIS record was changed<\/SPAN><\/P>

SOURCE: 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 Works<\/SPAN><\/P>

SOURCETYPE: Accuracy context for the record<\/SPAN><\/P>

AncillaryRole: Attribute that indicates whether the junction pushes (source) or pulls (sink) flow in a geometric network. Default setting for the GIS Consortium is none.<\/SPAN><\/P>

Enabled: Boolean field to indicate whether water is allowed to flow through this feature<\/SPAN><\/P>

ADMINISTRATIVEAREA: Owner of the area in which the feature is located<\/SPAN><\/P>

INSTALLDATE: Date of installation for the real-world feature represented in the feature class<\/SPAN><\/P>

LOCATIONDESCRIPTION: Statement illustrating the whereabouts of a feature<\/SPAN><\/P>

OPERATIONALAREA: Retired field used to store a description for an operational area designated by a community<\/SPAN><\/P>

ROTATION: 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 world<\/SPAN><\/P>

LIFECYCLESTATUS: Current state of the real-world feature<\/SPAN><\/P>

SUBTYPE: Additional designation of the feature. Includes the following: <\/SPAN><\/P>

  • air control: Used with a water system pressure tank for controlling the volume of air in the tank<\/SPAN><\/P><\/LI>

  • air gap: An unobstructed vertical space between the water outlet and the flood level of a fixture used for backflow prevention<\/SPAN><\/P><\/LI>

  • air release: Allows the air in the pipe to escape thus preventing damage to pipes and fittings<\/SPAN><\/P><\/LI>

  • altitude: 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 level<\/SPAN><\/P><\/LI>

  • atmospheric vacuum: A backflow prevention device used to prevent non-potable liquids into the drinking water system<\/SPAN><\/P><\/LI>

  • backflow control: Open in the direction of normal flow and closed with the reversal of flow; commonly found near pump stations and reservoirs<\/SPAN><\/P><\/LI>

  • cv combination: A spring loaded check valve that uses pressure to regulate water flow between the inlet and outlet<\/SPAN><\/P><\/LI>

  • double check: A type of check valve used to prevent backflow from potentially allowing contaminated water back into water supply lines<\/SPAN><\/P><\/LI>

  • pressure vacuum: A backflow prevention device that opens automatically when water pressure reaches a preset limit to relieve stress on a pipeline<\/SPAN><\/P><\/LI>

  • reduced pressure backflow: Backflow prevention device used to protect drinking water from contamination<\/SPAN><\/P><\/LI>

  • RPZ: 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 drain<\/SPAN><\/P><\/LI>

  • simple check: A valve which normally allows fluid to flow through it in only one direction<\/SPAN><\/P><\/LI>

  • vacuum breaker: Prevent a siphon from allowing a contaminant or pollutant into the potable water system; protection from high/low hazard or toxic substances <\/SPAN><\/P><\/LI>

  • vacuum release: Designed to relieve excess pressure upstream\u202ffrom the line<\/SPAN><\/P><\/LI>

  • vacuum valve: Used to control gas flow into a chamber, isolate, vent, provide relief or control conductance<\/SPAN><\/P><\/LI><\/UL>

    WORKORDERID: Unique work order identifier<\/SPAN><\/P>

    ELEVATION: Ground level height of real-world feature; measured in feet above sea level<\/SPAN><\/P>

    WATERTYPE: Designation of water distribution or collection system to which the feature applies<\/SPAN><\/P>

    DIAMETER: width of the real-world feature represented in the feature class; measured in inches<\/SPAN><\/P>

    LEGACYTYPE: Retired GIS tracking code for the feature<\/SPAN><\/P>

    DEVICEID: Unique identifying code for the mechanical part, such as a serial number or model number<\/SPAN><\/P>

    COMMUNITYID: Unique identifying code selected by the community<\/SPAN><\/P>

    OWNERSHIP: Organization with jurisdiction over the real-world feature represented in the feature class<\/SPAN><\/P>

    MAINTAINED: Organization responsible for the care of the real-world feature represented in the feature class<\/SPAN><\/P>

    DESCRIPTION: Statement illustrating the feature<\/SPAN><\/P>

    FID_WSJUNCTIONANNO_LINE: Unique identifier that can be joined to the FEATUREID field of the wsJunctionAnno_LINE feature class to provide a link between the feature and its label<\/SPAN><\/P>

    CATEGORY: Retired field required for ArcGIS coverage models<\/SPAN><\/P>

    FID_WSUNDERGROUNDENCLOSURE_POLY: Unique identifier that can be joined to the FEATUREID field of the wsUndergroundEnclosure_POLY feature class to provide a link between the feature and the polygon<\/SPAN><\/P>

    REPLICAFILTER: Code used to filter data for the creation of custom geodatabases<\/SPAN><\/P>
