What steps can be taken to build a well in the garden?

All domestic groundwater collection works (wells and drills) must be declared by the mayor at least 1 month before the start of work. You must fill out a work return form.

Statement of work: domestic sampling, well and drilling

This form must be accompanied by an extract from the cadastre (or a map of the location of the work at the scale of 1/25000) which can be obtained online:

Search, consultation and ordering of cadastral map sheets

All documents must be sent to the town hall by registered letter with notice of receipt.

Before starting your work, you must report your project to underground network operatorsby means of a teleservice:

Teleservice Networks and piping

If you intend to build a well over 10 meters deep, you must also file a prior declaration with the Regional Directorate for Environment, Development and Housing (Dreal), at least 1 month before the start of work. Your Dreal will inform you about the form to complete.

Once the well is built, if the water you are going to take is for human consumption, an accredited laboratory must perform a water analysis.

No later than 1 month after the end of the work, you must report completed work on the initial declaration of work form, attaching the results of the water analyzes of your well. This declaration is sent by registered letter with notice of receipt to the town hall.

In order to prevent the risk of pollution of the public water system, a drinking water service agent can access your property and check your well on the basis of the information contained in the declaration of work deposited in the town hall. Only water service subscribers can be monitored..

In the event of a risk of contamination of the water of the public distribution system, the service shall ask the subscriber to implement the necessary protective measures. If these measures are not implemented, the service may close the water connection.
