Stormwater Management Facilities

In June 2024, Amanda Pinto and Brendan Hummelen represented Crozier at the Canadian Water Resources Association National Conference in Saskatchewan, where they presented the findings from our stormwater management facilities research with Wilfrid Laurier University. The presentation focused on two research ponds in the City of Waterloo; the Dorwood Pond and the Yarmouth Pond. Water quality had been measured at the inlet and outlet of these facilities over a period of one year. Under existing monitoring requirements, continuous monitoring of these facilities was not required. As such, their year-round performance was often unknown.

Based on the results from the findings, we came to the conclusion that seasonality had an impact on the water quality in the pond and downstream. We also observed incredibly high concentrations of chloride entering these facilities indicating the need for source control. High concentrations of contaminants could cause biotic effects downstream of these ponds and impact aquatic life.

On May 31, 2021, Amanda Pinto represented Crozier at the Canadian Water Resources Association National Conference to present the most recent findings in our stormwater management facilities research alongside our research partners from Wilfrid Laurier University.

 

Stormwater management (SWM) ponds are among the most common approaches to stormwater management in Ontario, often as part of a treatment train.

Vegetation is a key but often overlooked component of SWM ponds; there is little information regarding targeting vegetation plantings to optimize treatment functions.

We have undertaken a comprehensive survey of stormwater management pond vegetation and its relation to hydraulics and water quality to better inform stormwater management pond design and optimize its functionality.

Our sites in southern Ontario have been selected based on the availability of design specifications and monitoring of water quality and hydraulics. Vegetation characteristics (species richness, diversity, evenness, percent cover, density) are being quantified and water quality samples obtained from the inlet and outlet. Water samples are being tested for BOD, COD, TSS, and pH.
