The long term care facility was constructed in 2009 in Corner Brook, on the west coast of Newfoundland. It is a Leadership in Environmental and Energy Design(LEED) Certified project. The Abydoz Engineered Wetland treatment system is used to treat all the sewage generated at the facility and was instrumental in acquiring LEED points for the overall project

Process
The wetland system is comprised of two horizontal flow wetland beds designed to provide treatment in parallel or in series. The first bed is a bilateral horizontal bed, such that its inlet is in the center of the bed and flow moves outward to both sides, bilaterally.
In regular operations both beds will operate in parallel mode. The system can also operate in series-mode to increase levels of treatment.
