The Water Guardian project first began as an avenue to protect our streams and rivers from impacts by stormwater runoff and flooding. Stormwater is the water an area will receive from rain, snow, and/or ice. Stormwater runoff is the water from rainfall or snowmelt that can no longer infiltrate into the soil and instead will flow over surfaces, and often will catch and carry harmful pollutants that enter our local waterways over impermeable surfaces such as roofs, parking lots, and roads. Flooding events will catch pollutants similar to stormwater runoff but often at a larger scale. To reduce these inputs, the PWA have turned to the strength of green infrastructure! These innovative installations can take the shape of a rain garden, green roof, or retention pond to name a few.

Green infrastructure can refer to a naturally occurring area providing valuable ecological services like a wetland, or nature-based infrastructure that can be installed like rain gardens or retention ponds. Rain gardens mimic naturally found spaces that are most effective in flood mitigation and filtering stormwater runoff. Incorporating these structures will create more green spaces while aiding in the offset carbon emissions by capturing particulate matter. They can also provide habitat for wildlife in the form of rain gardens, bioswales, green roofs, and naturalized ditches.

The PWA successfully installed 4 rain gardens within the tri-community area in 2019, with hopes of greening more of our watershed!

The Centennial rain garden in Centennial Park

The PWA installed 4 rain gardens from the end of September to November 2020 within the watershed communities of Riverview, Memramcook, Moncton, and Salisbury.

The Redwater Park rain garden in Riverview


In Salisbury we built our first residential rain garden


The College-Bridge Ballfield rain garden in Memramcook extending EOS’ rain garden
