Service areas and supply zones
Every pressure zone, supply district or maintenance territory borders others. When a valve setting changes or a district is reorganised, the line between two zones moves, and both zones must change in the same edit.
- Move a zone border once for both zones
- Split a supply district when the network grows
- Merge two maintenance territories into one
- Trace a new zone along existing zone borders
- Keep zones, routes and labels in a layer tree
