The CityGreen® modular StrataCell system® was the system of choice for the water harvesting project at Mill Woods Sports site conducted by the City of Edmonton in Alberta, Canada.
The harvesting system has been designed to function as a passive recreation facility for a small lake, which collects water and provides irrigation to the surrounding sports fields in the 40 hectare site.
The StrataCell structural soil cell system was installed in a continuous trench along the centre of the south parking lot to provide a filter/storage system for runoff water and at the same time, provide soil volume for six trees installed within the matrix.
The water runoff drains into the centre of the parking lot through permeable surfacing, then filtered/stored within the StrataCell system filled with washed rock. Once the water has filtered through the matrix, it reaches a perforated pipe, which is tied into the storm sewer and transferred to the storm water lake located on the southeast side of the park. The perforated pipe continues beneath trees to transfer the water to the storm line.
Natalie, a landscape architect from Stantec, says the project is expected to be finished in July 2012. They are currently waiting to pave the area and install the plant materials.
Citygreen will be posting an update on the completion of this great project – Watch this space!
