Long-distance pipelines are feeder pipelines over longer distances that serve transport purposes. However, they are also defined as feeders, from the reservoir or pump station to the supply area, or used to connect different supply areas (organizational units).
Main lines have a superordinate distribution function within large service territories (major cities). They usually do not have a direct connection to the consumer (Fritsch et al., 2011). The connection lines to the consumers branch off from them.
Connection lines begin at the branch point of the supply line and end with the main shut-off device of the consumer (usually in the connection room of the building).
ServiceLines are usually distinguished more precisely. This includes the collection of whether the line is used by one or more end-customers. If possible, this should be done by means of an evaluation and any internal lines must be taken into account.
Internal line starts with the main shut-off device of the consumer (usually in the connection room of the building). These are the lines within the building or area for which the consumer is responsible.
Line connecting the hydrant to the supply line (DistributionLine). This has the same character as the ServiceLine.
In Switzerland, the hydrant is not connected directly to a supply line. Connections of sprinkler systems (extinguishing system) can also be connected with the HydrantLine.
