| Home > services > Pressure_Reducing_Valve (FeatureServer) | | API Reference |
The PRV dataset is a water model required feature class that is consumed with it's specific behaviors set as rules for long term planning of the water system. Their positions also delineate the pressure zones that exist within the City's water system. Locations are derived from as-built drawings and have their locations verified with a survey grade GPS unit.
