They probably don't have a picture of the flood from a few days ago on their page

You sure it is a flood? It is halfway up the tower but, it's one big ass tall tower. There may have more than one spot (roof) to bleed the system.

Someone on UT was saying it happened around the 30th to 35th floors

No clue really. I'm curious what would be the most powerful water pump used in these developments and how high it could pump the water.

FrankieFlowerpot · #**3850** Posted **Jul 20, 2017, 3:53 PM**

These towers have a intermediate mechanical room located on the 43rd floor. I'm guessing they have additional pumps in there

Water pouring out the side of a building is pretty much exclusively a sign of something gone wrong. Anything that would need to be bled would be piped to drain (sprinkler dump valves) and you'd generally only bleed closed loops for heating or cooling at the top of the loop (to bleed air) or at the bottom (to dump the system)

You can get pumps that have enough head pressure to pump as high as you want, really. For instance any building above four stories will have a fire pump capable of pumping water at significant pressure right out the top of the building

So the pipes can withstand the pressures to get water up to 70 storey high? Are then the intermediary pumps throughout the building to control downward pressure from the roof top storage tank or am I completely lost about things.

Oh yes, they'll use rolled steel pipe with either welded or victaulic connections that are capable of withstanding significant pressure. My sprinkler standpipes are pressurized to 300psi, and I am sure you could go a lot higher than that without issue. One of my last buildings had a rooftop storage cistern for fire protection, in that instance no pump is required at all, it's filled with the domestic booster pumps and all gravity fed should a sprinkler head let go. They don't do a lot of rooftop storage anymore though. It's generally just a big pump, something like this:

Very cool. thanks for sharing

That was some pretty neat highrise knowledge I had no clue about!

240glt · #**3858** Posted **Jul 20, 2017, 10:51 PM**

Lots of stuff goes on behind the scenes in buildings that are not sexy or glamourous, but still interesting. There are so many different systems that most aren't aware of. I've been either involved in commercial and institutional construction or management of high rise office buildings since 1999 and I still run into new things all the time.

Pretty much guaranteeing this will be the biggest office skyscraper project, I will see go up in my lifetime.
