Works at less than 5 metres: tell Fluxys’ regional operating sector 48 hours in advance

If you plan to carry out earthworks within 5 metres of a Fluxys pipeline, you must tell Fluxys, even if you have already notified Fluxys of the works and we have already sent a patrol officer to inspect your site before the works began.

Our patrol officer will then set time aside in the inspection schedule to come and inspect the works taking place within 5 metres of the pipeline. To tell Fluxys about your works, you should contact Fluxys’ regional operating sector.

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.
