CleanStormWater -project meeting and a pilot site visit was organized by Turku University of Applied Sciences (TUAS) in April 2022. The first time in the history of the project we were able to have a live meeting, as covid restrictions ended.
In addition to face-2-face brainstorming in workshops, Finnish pilot sites and TUAS laboratories were visited. At the time of pilot visit, the bioretention bond treating stormwater from traffic area at Turku Länsikeskus was still waiting for warmer weather and planting of vegetation. However, monitoring of the site was started already in January and first water quality results were promising.
