Lots of cities around the world, including Toronto, have (at least partially) what is called a combined sewer system. If the sewer system was built prior to the 1940s and it hasn't been replaced, there's a good chance that it could be a combined system. About a quarter of Toronto and about 60% of New York City still run on combined systems.
What this means is that both stormwater and sewage run in the same pipes. Most of the time this is fine, but if there's a heavy precipitation event and the system backs up, then you have poop getting diverted into rivers, lakes, and other bodies of water. In Toronto, this happens in places like the Don River and the inner harbor, and in Paris it happens in places like the Seine.
I was recently reading something suggesting that sewage generally gets dumped into the Seine about 12x per year as result of major rain events. This is why it's such a difficult and expensive task to make these bodies of water swimmable, which is something that Paris wants to do before it hosts the Olympics next year.
Thankfully, Toronto also wants to do the same. And in 2018, it started construction on the largest stormwater management program in the city's history. The overall budget is about $3 billion. Once complete, it should more or less eliminate combined sewer overflows, meaning our waters will become a lot cleaner and more swimmable.
This certainly isn't the sexiest capital project to announce and talk about. It largely happens behind the scenes. But it is going to lead to a significant quality of life upgrade for the cities willing to take it on -- one that will pay dividends well into the future.

One of the most exciting city building projects going on in Toronto right now is the revitalization of the 715-acre Port Lands area (here's a map if you'd like to get situated). Despite its massive scale, it doesn't seem to be receiving a lot of attention. And that's probably because, at this stage, it's mostly infrastructure work. It's just a lot of soil being moved around.
But it's of course important work. The mouth of the Don River (where it meets Lake Ontario) was never properly engineered for resiliency, and so the entire area is at risk of flooding. That's why this $1.25 billion effort to re-naturalize its interface is currently underway. The above video does a good job explaining just what that entails.
At the same time, it is creating a wonderful city building opportunity -- new parks for the illegal drinking of craft beers, new wildlife habitat, new meandering rivers for kayaking, and of course new housing and new jobs. But when you look at what's planned, it's hard not to feel like we're missing the mark in terms of density.
The plan for Villiers Island calls for some 4,900 homes (according to this Globe and Mail article). And the plan for the entire area calls for only about 20,000 homes (according to this recent Bloomberg article). Surely there's room for at least a few more -- especially if we're hoping to support a new LRT line to the area.

My good friends over at Urban Capital recently released a short film about the making of their River City project here in Toronto. (If you can't see the embedded video above, click here.)
For those of you who aren't familiar, River City is a 4-phase development on the east side of downtown that was really the first project in what was known as the West Don Lands area. Urban Capital secured the right to develop the then government-owned lands in 2008 through a public tender process that was run by Waterfront Toronto.
It's a tricky and unobvious kind of site in that it's surrounded by infrastructure and it came with a whole host of development challenges, including flood risk. But the team figured it out and River City has gone on to win a number of awards including the Ontario Association of Architect's Lieutenant Governor’s Award for Design Excellence.
River City is an important project for Toronto in that it dared to be different. It's like no other project in the city, and I'm not just saying this because they're my friends. I'm saying it because I want our city to be a global leader in architecture, design, and development, and to continue to push the envelope.
River City did exactly that.
