Project Description: A DoubleTrap stormwater detention system was needed to replace an existing stormwater detention pond under a local park in the South Unionville neighborhood of Markham, Ontario.

Challenge: The main challenge of this project was to meet the Ontario Ministry of the Environment and Climate Change guideline for enhanced water quality control that requires 80% total suspended solids (TSS) removal.

Solution: StormTrap designed a full-scale underground stormwater detention wet pond, complete with a forebay and a permanent pool of water under the complete stormwater detention area. The system achieved 82% removal efficiency for TSS.
