The Catalan Water Agency (ACA) publishes the service ACA - Overhead and Underground Crossings of Lines and Pipelines in the Hydraulic Public Domain (DPH), which allows to request the authorization to carry out aerial and underground crossings of lines and conduits in hydraulic public domain (DPH). The characteristics of these crossings are:
- Overhead line crossings in DPH they are works that occupy the flight of a channel of the hydraulic public domain. In general, these are wiring or pipes that cross a channel (being able to take advantage of other existing passage structures, such as bridges, drawers, viaducts, ..) so that their support structures are located outside the channel.
- Underground crossings of lines and conduits in DPH they are works that cross a channel in an underground way occupying the hydraulic public domain.
