| Title | Living Soil Filtration Project |
| Organization(s) | The Town of Okotoks in partnership with Source 2 Source Environmental Design, Bow River Basin Council, City of Calgary and the Universities of Calgary and Victoria |
| Water quality issues |
|
| Location/place | The Town of Okotoks – adjacent to the Environmental Education Centre |
| Sector | Municipal – 2018 winner in the water category of Federation of Canadian Municipalities’ (FCM) Sustainable Communities Awards |
| Funding sources | Watershed Restoration and Resilience Program (WRRP) and others |
| Timeframe | 2014 – present (ongoing) |
| Project cost | Initial funding from the Watershed Resiliency and Restoration Program (WRRP) was $125,000. With the addition of research partners and more stakeholders the funding at the site has reached approximately $1.2 million. |
The Town of Okotoks has an existing public works yard and wastewater treatment plant immediately adjacent to the Sheep River. In keeping with their long-standing leadership in sustainable design, the Town sought a riparian bioretention installation to serve as the main stormwater management facility for this site. Different soils and plants in the wetland (bioretention installation) capture and filter stormwater to increase the quality of runoff that is eventually released to the Sheep River. The installation, like natural wetlands, also acts as a buffer to reduce risks of flood and drought.
Conventional flood mitigation techniques often address a limited set of the consequences of a flood, whereas absorbent landscapes are designed to enhance basic processes at their source. The Source 2 Source (S2S) vision is to utilize the hydrological functionality of plants and permeable soils to establish self-sustaining riparian systems that would beneficially alter site scale water cycling, and reduce the risks of flood and drought. Vegetated bio-retention features are capable of capturing, storing, and gradually releasing water, all of which cumulatively prevents rapid fluctuations in surface water and lessens frequency and severity of flood and drought occurrences. Correctly designed, such features also have many ancillary benefits such as nutrient and contaminant capture, biodiversity, and natural aesthetics.
There was a need to manage stormwater runoff from a public works yard and wastewater treatment plant adjacent to the Sheep River, as well as interest from the research community to investigate processes and interactions in riparian bioretention. This initiative was created to address both water quality and quantity concerns as well as provide valuable information that can be used for future initiatives like this one.
