The East Bowmont Stormwater Project in Calgary, Alberta, Canada was needed to polish major stormwater trunk flows draining approximately 1750 ha of Calgary’s municipal lands prior to discharging to a proposed £7.5 million constructed wetland complex.
The project featured a 90 m diameter high performance Nautilus Pond™ sediment removal preconditioning element designed and developed by the Calgary based firm Source2Source Inc. which enables removal of more than 95% of particles 50 µm and larger diameter at a continuous 5000 L/s flow rate. Construction has commenced on the project with commissioning expected in the summer of 2017.
The Nautilus Pond™ design philosophy can be further scaled up to larger flows and applied to a wide range of treatment scenarios including landfill leachate and tertiary wastewater treatment where the desire is to create a robust environment to enable settling.
