Drilling a water well cannot be carried out without the proper authorization. In Catalonia, licenses and permits are managed mainly by the Catalan Water Agency (ACA). Below, we explain step by step how to obtain them.

Sondeo authorization request

You must submit a technical project signed by a certified professional, including plans, estimated depth, and the intended use of the water.
The ACA evaluates the risk to aquifers and protected areas before granting the permit.

Well registration

Once the work is completed, the well must be registered with the ACA, providing: exact coordinates, final depth, diameter, and intended use.

Municipal license

Some municipalities require a construction or installation permit, especially if the well is located near roads, urban areas, or industrial zones.

Discharge authorization (if applicable)

If the extracted water is used for irrigation or open systems, an additional discharge or surplus-water authorization may be required.

Practical tips

• Check whether the land is located within a hydrogeological protection zone.

• Avoid drilling without a permit: fines can exceed €10,000.

• Hire a specialized company to manage all the paperwork for you.
