So, this UW-Madison chilled water break happened on June 17, though AC wasn't reduced on campus until later in June. Only yesterday (July 13) was this stated in a campuswide email:
To give you an idea of the scope of the challenge, the pipe that broke is approximately 4 feet in diameter, buried 20 feet underground, and is surrounded by other buried utilities. Before repairs can begin, the adjacent infrastructure is being stabilized, and soil retention is being installed so the site can be fully excavated, and the entirety of the situation can be assessed.
I don't question the need to stabilize the surroundings first. This explanation just seems like something I would have shared earlier. (They've been sending weekly email updates since the end of June, making this the third update.)
This week is hotter outside, and therefore hotter inside the buildings that aren't healthcare/labs with living subjects but aren't closed. It's been 78 degrees in my library office all morning.
Oh, and I was wrong about the fuel for the rented chillers. They're diesel fueled, or so is my guess based on the daily visits from the Dieselex fuel tank.
