Point Feature Classes

The utility points of the water data model are stored in separate attribute feature classes, one for each point type. They are grouped in the Point topic.

Geometry is stored separately from attribute data. The network point geometry is stored in the Point feature class in the Topology topic.

Each point feature class has a corresponding label feature class with one default label definition.

Most point feature classes have an associated model table (*_MODEL). Reservoir and Source do not have model tables. Model tables can be found in the Administration topic of the data model, under Manufacturer.

Feature Class Name	Table Name	Description
Armature	WA_ARMATURE	An armature is an assembly that connects pipes.
Emitter	WA_EMITTER	An emitter is a drip irrigation component that dispenses water to plants at a known rate.
Fitting	WA_FITTING	A fitting is used to connect, cap, or plug a pipe carrying water.
House Connector	WA_HOUSE_CONNECTOR	A house connector is a service connection point on or inside a building. It is the last point of a water network and represents the connection between the network and the consumer/customer.
Hydrant	WA_HYDRANT	A hydrant is an apparatus that dispenses fluids.
Meter	WA_METER	A meter is a device installed in a line for measuring the quantity and rate of water flowing to a facility or through a section of line. You can use the related feature class WA_MAINTENANCE to create events such as meter readings, installation, mounting, or calibration. For more information, see Maintenance.
Pig Launch	WA_PIG_LAUNCH	A pig launch is a point where a pigging device is inserted to clean up a pipe fitting.
Pressure Reduction	WA_PRESSURE_REDUCTION	Pressure reduction is a water system component that reduces the downstream pressure of water. It is used in irrigation systems, particularly drip systems.
Pump	WA_PUMP	A pump is a mechanical device for a water system that draws material into itself through an entrance port and forces the material out through an exhaust port.
Reservoir	WA_RESERVOIR	A reservoir is a body of water that supplies water to a water distribution system.
Sample	WA_SAMPLE	This feature class stores point locations where one or more water samples are collected from a water utility or system.
Source	WA_SOURCE	A source is the point from which water is supplied for processing and distribution.
Tank	WA_TANK	A tank is an above or below grade receptacle or chamber used for holding water on a temporary basis prior to transfer or use.
Valve	WA_VALVE	A valve is a fitting or device used for shutting or throttling flow through a water line.
Vent	WA_VENT	A vent is a valve installed in a line to either release air trapped in the line, and/or allow air into a line to relieve a vacuum condition.
