SUMMARY:SIANI Event: Spectacular Outdoor Wastewater System
LOCATION:Alhagen
DESCRIPTION:This  large wetland of 28 hectare is  the final step of a waste water  treatment (following mechanical and  chemical processes). The wetland  was built instead of retrofitting the  existing plant by conventional  methods for nitrogen removal, a choice  that has been found very wise.
