Surface visibility

Indication of presence, not exact location

On the surface, the path of a pipeline is marked out using beacons and markers. However, it should be borne in mind that a beacon or marker only shows the route of a pipeline and does not tell you its exact location. To determine the exact location and depth of the pipeline, you should contact Fluxys’ regional operating sector. A patrol officer will come on-site to mark out the course. 

 

Different kinds of beacons and markers

  • Beacons are intended for use by Fluxys helicopter patrols.
  • The measuring posts are used for monitoring a pipeline's cathodic protection system. They are not markers as such, but indicate the presence of a pipeline as well.
  • PVC markers are placed at the boundary of the nearest plot.
  • PVC markers with flat head are placed beside railways, waterways and verges.
  • If the pipeline is beside a road, there will be markers in the road surface. 

Tips for using search operators

Use "quotation marks" to search for a series of words or a phrase in a specific order.

Boolean operators

You can find a group of words or a phrase by using the link words AND, OR and NOT:
known as Boolean operators, these words are used to combine terms in the search field.

  • AND: All the search terms must be included in the publication. Typing in Apple AND Pear will return publications containing both the word Apple and the word Pear.

     

  • OR :  At least one of the search terms must be included in the publication. Typing in Apple OR Pear will return publications containing either the word Apple or the word Pear or both.

     

  • NOT: The term preceded by NOT must not be included in the publication. Typing in Apple NOT Pear will return publications containing the word Apple but not the word Pear.
