Constructed throughout the 1930s, the R.C Harris Water Treatment Plant (pictured above) is the largest water treatment plant in the City of Toronto. It produces over 120,000 million liters of water each year, which represents about 30% of Toronto's drinking water.

Designed by Scottish architect Thomas Canfield Pomphrey, it is also the city's largest collection of Art Deco buildings. This makes the complex pretty unique. Because it was designed to be both a critical piece of municipal infrastructure and an architectural icon.

If you've ever visited the grounds, you'll know that the plant is the furthest thing from utilitarian. There's an opulence to the buildings and an incredible attention to detail, both of which are characteristics of the Art Deco movement. And if you've never been, I would encourage you to go.
