Represent all Tucson Water NON-POTABLE pipelines types except for service connections to individual customers; this data set includes some known privately owned mains. Pipes are categorized in two major types. A distribution main is a pipeline generally 16" or smaller which delivers water to the service lines within a given area. A Transmission main is a major pipeline that moves water from its source to a service area. These pipes are usually larger than 16". See the Supplemental Information section for more discussion on NON-POTABLE data sets. |
