évolutions réglementaire et normative de l’assainissement non collectif : comment modifient-elles en profondeur le paysage technique ? Recent evolutions on French regulation and normative documents about on-site treatment: How do they also change the technical aspects?

En France, la réglementation relative aux prescriptions techniques applicables aux installations d’assainissement non collectif ne cesse d’évolueret conduit à l’apparition sur le territoire de nombreux produits comme les micro-stations . Cette note réalise un focus des principales évolutions et fournit un tableau de classification de ces filières. The regulation relative to technical requirements applicable to on-site treatment evolved in 2007. It introduced the possibility of implementing new types of approved wastewater treatment plant. It also described guidelines to get new treatment plant approved. Experimental tests have to be carried out which duration depends on tests carried out beforehand during a EC marking. This regulatory evolution has led to the appearance on the French territory of numerous new products, called "micro-wastewater treatment plant”. The present note first provides a focus of the main regulatory evolutions and then proposes a classification of the recently introduced wastewater treatment plants.
