Greywater Treatment Garden
Royal Winter Fair, Toronto

An exhibit showing how a beautiful and ecologically sustainable garden treats residential greywater with the Clivus Multrim Greywater Treatment System. Visitors walk through the process. In the Greywater Tea House, visitors learn that greywater is wash water from the kitchen, bathroom and laundry. Following the water down the drain, they see it directed to a filter box that removes particles of food, lint and hair. The water is pumped out of the filter box into perforated pipes near the surface of the garden, the most biologically active region of the soil. The greywater circulates through the garden bed, providing nutrients for fertility, sustenance and growth to plant roots and other life forms, thereby removing polluting substances and purifying the water. The purified water is then used for the pond, where a bronze figure by Canadian sculptor Liardi is about to dip her toe, demonstrating the fresh quality of the treated water.
