Saint Sulpice la Foret : a 1000 PE waste stabilization pond boosted to 1950 PE by addition of reed bed filters. A 2,400 m², vertical flow reed bed (French system), a 1,950 m² second stage vertical flow, unsaturated plus a 10,000 m² of willow plantation and a 5,000 m² pond treating 400 m3/d of domestic effluent.

The municipal centralised treatment plant (a classic activated sludge technology) for the wastewater produced by the municipality of Jesi (Ancona province – central Italy) has been upgraded in the year 2002, with the realisation of a new “nitrification-denitrification” compartment and a hybrid Constructed Wetland as polishing stage. 

Grenoble – urban park Ouagadougou: a 1 ha urban park with reed bed filters and surface flow wetlands collecting and treating stormwater runoff from the roofs of buildings and from adjacent roads in order to meet irrigation needs of the park and to reduce discharge of stormwater into the municipal sewer system. This project was the laureate of the NOVATECH 2013 international conference of sustainable urban drainage award http://novatech.graie.org/a_present_laureats.php
