Status report on wastewater-treatment plant compliance with standards (data 2008)

A national action plan to upgrade the wastewater-treatment plants (WWTP) of French cities and towns was launched in October 2007 by the Ecology ministry. The government committed to bringing into compliance by the end of 2011 (taking into account reasonable technical lead times) all urban treatment plants that were not up to standards in 2006. The WWTPs that no longer met standards in 2007 and 2008, notably following their classification in sensitive zones for the treatment of nitrogen and phosphorous, were granted an additional two years to comply, i.e. until the end of 2013. This document reports on the degree of compliance achieved by wastewater-treatment plants.
