Dow’s Lake is a central part of Ottawa’s Rideau Canal system—a place where people skate, paddle, and relax year-round. But beneath all that activity, the lake is struggling with poor water quality, algae blooms, and a lack of healthy shoreline habitat. That’s where our project comes in.
We’re designing and installing modular floating wetlands that filter stormwater, support native plants and wildlife, and create a more vibrant, resilient ecosystem. It’s a practical, scalable solution that improves the environment without getting in the way of how people already use and love the space.
Let's Break It Down
Each layer of our floating treatment wetland (FTW) design plays a critical role in supporting ecological function and system durability. At the surface, a cork planting matrix holds native wetland plants in place, allowing them to grow and absorb nutrients from the water. Just below, a submerged root cage provides habitat for fish and invertebrates while hosting microbial biofilms that break down contaminants. The welded aluminum frame offers structural support, anchoring the unit while allowing it to move with seasonal water levels. Together, these layers create a modular, low-impact system that filters runoff, supports biodiversity, and blends seamlessly with the surrounding environment.
This project delivers real environmental and community impact—cleaner water, more biodiversity, and a living system that people can actually see and learn from. It’s not just about planting things; it’s about creating a healthier, more connected space where ecosystems thrive and the community gets to be part of it.
