Okotoks Bioretention Research
The Town of Okotoks Operations Centre is the home of a long-term research site. ALIDP Director Anton Skorobogatov is the first student undertaking bioretention research on the site through the University of Calgary with lead investigator Dr. Jennifer He.
Twenty-four 2 m by 2 m beds compare the performance of three media types and the influence on and response of native perennials and woody species. Two of the media under investigation meet the specifications set out in the City of Calgary Bioretention and Bioswale Design and Construction Module. The third media is loam amended with a large proportion of organics. Let the trials begin!
This long-term research site is fully monitored for water quantity and quality with a synthetic water application and contaminant-dosing regime. These beds were planted in 2017 and experimental runs began in earnest in 2018. See the presentations from the 2018 site visit in the related files for more information.
The ALIDP is spearheading an additional number of smaller experimental cells to investigate amendments for phosphorus removal. If you know of a potential amendment to be investigated or of a student who would like to be involved in this work, please contact the ALIDP.
