Description
This systems approach study will supply practical information on the technical and cost aspects of the innovative option,suggested by published research, of redeveloping an obsolete, lagoon-based wastewater treatment plant into aconstructed wetland that will provide state-of-the-art tertiary treatment for municipal wastewater; reduce future capitaland operating costs and energy use compared to similar treatment options; and create attractive urban green space andwildlife habitat that also serves as municipal wastewater treatment infrastructure. If shown to be the case by this project,such retrofits could transform an increasingly common Canadian municipal liability (decommissioned sewage lagoons)into a long-term asset (attractive urban green space wetlands) and reduce the need to dedicate other open space forfuture water treatment. The findings will be relevant for many small municipalities facing similar wastewater infrastructurereplacement situations.
