Toronto’s Water: exploring where it flows from and where it flows to

October 4, 2023 @ 7:00 pm 8:30 pm

Register Now
In a big city like Toronto, it’s easy to live unaware of the massive water flows that support our daily existence. Have you ever turned on the tap and considered how exactly the water got to you? Have you ever flushed the toilet and thought, where it is all going? After a rainfall have you ever wondered where all the rain disappears to? This talk for the curious explores Toronto’s water, sewage, and stormwater infrastructure in a clear and engaging manner. Using maps, we’ll investigate where TBG’s water, sewage and stormwater comes from or goes to! We will learn about the Leslie elevated water tank, the Coxwell Sanitary Trunk Sewer, Wilket Creek, and more. Don’t miss this opportunity to deepen and foster a stronger connection to place. As Mariko writes, “Once we know where things come from and where things go, we are no longer lost. We are connected and have a foundation upon which to develop a caring relationship with our environment.”

Wednesday, October 4, from 7-8:30 p.m. Doors open at 6:30 p.m.

TBG Member $ Free, TBG Guest ticket $5, Public $20 (plus applicable taxes and fees)
