Liz Horvath From: Scott Horvath Sent: Monday, May 6, 2019 1:30 PM To: Liz Horvath Subject: Memo to BPW Memorandum TO: The Board of Public Works FROM: Scott Horvath DATE: 5-6-19 EMERGENCY MAIN [ZEPAIR On 4-26-19 at approximately 2:42 pm the water works received a call about water coming up in the 20200 Auten Rd. One of the tech's went out to assess the situation and relayed back to the meter room it was a class 5 leak meaning over 250 gallons a minute. By the time he had reached the area and seen what was happening it was after 3:00 pm when the construction & maintenance staff leaves for the day. The meter room dispatcher called the job leader on call to inform him of the leak. The job leader could not get a crew to come in for the repair, so he called me. While driving into the to the shop about 3:30 pm I had already seen a video of the main break and received the call from the job leader about no crew to do this repair. I called Scott Riley from Selge Construction before his crew left for the day to see if they could handle this repair. At 4:06 prn Scott Riley called me back and told me they have a crew heading to the job site to handle the repair. This wasn't typical a main break it had a 3" hole in the pipe and it was a catastrophic failure. Which meant we couldn't just put a full circle clamp on the pipe, it had to be cut out and replaced with another piece of pipe with two compression sleeves to put it back in service. This process took about 5 hours to complete and it took an additional 3 hours get the water back on to everyone. The area we had shut off encompassed over 2.5 miles of water main so we had to turn it on slowly to avoid breaking the pipe somewhere else. From our maps we initially anticipated this would have affected 1000 people and could not wait until morning to repair. Due to this main being on the very edge of our system and not looped in like most places it had to be handled accordingly. The classifications we use to account for water loss has 6 classes a class 5 the earlier mentioned projection was just a generalization, after the fact learning it was a 3" hole in the pipe it was displacing approximately 1200 gallon per minute. An emergency response was the only adequate response.
