Big condo fire in Prestwick last night, sounds like CFD used more than 3 million liters of water to fight it!

This sounds like an issue that has plagued pipes from the 70’s and many American cities have had similar catastrophic failures.
The PCCP repair and reinforcement project caused by mistakes of the 70s
Below specification PCCP installed across the US in the 1970s has left Amercian water companies facing massive repair and reinforcement projectspiperepair.co.uk
Basically they used less steel in the pipe thinking it was stronger, which causes the concrete to fail.
That's the question that I find the most intriguing. The water main is suppose to have a lifecycle of 100 years and yet it catastrophically ruptured at year 49.
Did the manufacturer lie about the pipe specifications?
Was the pipe under too much pressure?
Was the flow rate too great?
Was there a change in the way the city treated water since 1975 which affected the concrete and steel of the pipe?
was the pipe installed incorrectly?
The video of the fire was insane. I'm amazed it was limited to the roof. I wonder what caused it? Errant cigarette butt or roof repairs? Though it happened at 3:00 am I think, so it's hard to say.Big condo fire in Prestwick last night, sounds like CFD used more than 3 million liters of water to fight it!
The massive fire in Fort Mac was suspected to be started by someone on a quad chucking a butt.I'm curious how many fires are started by idiots pitching butts. The big fire in Millrise 14 years ago was a guy putting a butt in a planter on a super windy day. Lots of similarities with the Prestwick fire actually. I think a guy in Kelowna was charged with pitching a butt out the window of his car and starting a forest fire! All for what, to slowly kill yourself? I really don't get the point of smoking lol.
Probably many, but fewer than in the past due to declining smoking rates. Grass fires in Fish Creek and Nosehill parks used to be almost monthly occurrences compared to every few years now. Vehicle exhaust systems burn hotter now due to emissions controls and likely start more fires than in the past. All it takes is parking in tall grass.I'm curious how many fires are started by idiots pitching butts.

I remember nose hill being blackened basically every year in the 90’s. Now much more rare for sure.Probably many, but fewer than in the past due to declining smoking rates.

I can't find the news story anymore, but I remember they were out on an ATV trail around the area where the fire had started and identified a cigarette butt as the possible/probable cause. Maybe they've since ruled it out....idk? Apparently a number of fires in that area over the past decade have come from cigarette butts.I knew about the ATV part, thought it was grass caught on the muffler or something. Yikes!
I'd be really curious what happens to the overall water usage over time - sure it will go back up a bit, but there's that whole saying about it takes 3 - 4 weeks to form a habit in general. I wouldn't be surprised if water usage takes a long while to creep back up to "normal" or that the new normal is a bit lower than previous. Anecdotally, I did not find the restrictions overly impactful for my situation - but just made me really think about length of showers, really filling the dishwasher up etc.Will we have a new water normal. Pretty interesting that even though people threw their hands up that we were pretty successful at reducing water use.
It shows me, even after covid seemingly divided us, we can still come together and do what we have to for one another. It shouldn't take things like this to reassure me that things aren't so bad but it does.
Good job everyone, lets celebrate with a great Stampede.
It'd be interesting to see who the big water users are in Calgary. To see a residential vs. Industrial/Commercial split and to see a break down of of water consumption of a high-rise residential unit vs. SFH. In the last 20 years there have been a few golf courses which redeveloped into residential areas which probably helped out with the per capita water consumption. With that said I assume some of the golf courses along the river like Inglewood, McKenzie Meadows and Blue Devil have a water license and just pull it straight from the Bow river.I'd be really curious what happens to the overall water usage over time - sure it will go back up a bit, but there's that whole saying about it takes 3 - 4 weeks to form a habit in general.

Overall, the long-term Calgary's water usage story is quite remarkable, here's two graphs awkwardly shoved together going back to 1972 on daily consumption to give an idea of the trend. Tried to line it up so the line is approximately a consistent scale. We are on a consistent, downward trend in usage per person for decades.
Water usage peaked in the early 1980s at ~800 L / person / day. After a few decades innovation in appliance and fixture design, water meters and better awareness, by in 2023 we are at 351L / person / day. During these recent restrictions we were 20 - 25% even below that (~300 - 325 L / person / day). That's remarkable.

And it's not just us either making huge efficiency improvements. For comparison, here's a similar article from Las Vegas, a notably desert place with big time water issues. Converting the usage from gallons to litres for he graph below, they have trended similarly and are sitting at around 335L / person / day in 2023, very similar to Calgary.
