Occupation of a plot of land included within the protection perimeter for the purposes of carrying out the work provided for in article L. 1322-8 may only take place by virtue of an order issued by the representative of the State in the département, which sets the duration of the order.
When the occupation of land included within the perimeter or the application of articles L. 1322-3 to L. 1322-7 deprives the owner of the enjoyment of the income for more than one year or when, after the work, the land is no longer fit for the purpose for which it was used, the owner of this land may require the owner of the source to acquire the occupied or denatured land.
In this case, the compensation is set in accordance with the provisions in force for expropriation in the public interest.
In no case may expropriation be instigated by the owner of the spring.
