FAQ

The operator of a facility – in this case, you as an individual – is liable for the construction and operation of the facility in compliance with the applicable provisions and for all damages that may result therefrom. You should therefore check carefully that the drilling documents are complete. These should include:

the complete drilling report.

No. The Law of 19 December 2008 on water prohibits the direct or indirect discharge of water as well as other solid or gaseous substances. Groundwater heat pumps cannot therefore be authorised in Luxembourg.

The size of the installation must be calculated in accordance with VDI (Association of German Engineers) Guideline 4640. Ask your chosen drilling company for information on this subject.

You must ensure that you have obtained all necessary permits before the works start. Contact : forages@eau.etat.lu

The exact date of the start of drilling must then be notified to the water management authority in advance. Ensure that the drilling company and the installer coordinate their schedules.
