One of the contractors working here turned the power off to the sewer pump station on a Thurs....we're closed on Fridays...Sat security noticed/heard water under the stairwell of one of our buildings. The building has wide exterior stairs that go to the 2nd floor library...underneath is how you access the rest of the building...2 1/2 ft high of literally shi*t! That was an all day clean up and they had to call professionals out.
4 days later...on my way to work my boss is calling in a panic for me to get to the office ASAP because the sewer line had back up into the cafeteria...65 gallons of cr*p.
