The bioswales that are being installed along the roads in a new development in Mississauga, Ontario, is like a Brita filter for rainwater, says Lukasz Wagner, VP of development and construction with Port Credit West Village Partners.

That bioswale natural filtration system in the Brightwater development will be one of the largest systems in North America, and it is estimated that it will process and filter 300 million litres over the next 10 years. It also will help restore the Lake Ontario shoreline on which the development is situated.
