City Explains Water Main Break Repair Process
The city's Water Department outlined its comprehensive approach to repairing water main breaks in an educational presentation describing the step-by-step process used throughout the year.
Water main breaks occur most frequently during winter months when frost penetrates the ground, causing pipes to shift and become stressed, according to the department. Summer repairs prove more straightforward as water typically surfaces directly above the break location, while winter conditions and new road surfaces can redirect water flow, complicating identification efforts.
The repair process begins with throttling down water flow to prevent property damage and road surface impact, followed by requesting emergency locate services. Gas utilities, communication utilities and other providers mark their lines to prevent accidental strikes during excavation. When no obstructions exist, crews use excavator equipment with jackhammer attachments to remove hard surfaces and dig through frozen ground when necessary.
Workers install dig box safety equipment to prevent cave-ins before applying stainless steel repair bands with rubber lining to seal cracks in the water main. The department then charges the water main, checks for leaks and purges air from the system to prevent problems in residential connections. Crews backfill with fresh material and use tamper equipment for immediate road compaction.
The Water Department maintains staffing from 7 a.m. to 11 p.m. on weekdays with on-call coverage afterward. Officials encourage residents to report suspected water main issues early, noting that prompt response improves repair outcomes. Winter repairs receive temporary road patches, with permanent restoration completed during spring season.

Water Main Break Repair Procedures and Public Reporting
▸Meeting Analysis
“They're most common in the winter when the frost is going in the ground, the ground's moving, pipes are moving, that's when they get stressed.”
“If you have a clean hole, which means there's no other utilities or obstructions that we have to deal with, then we can use the excavator, which is behind me here. It's our fastest means of digging up the water main.”
“We'll take a stainless steel band and it's rubber lined on the inside and it just clamps down and seals the rubber around the crack. And that's actually what makes the seal to stop the leak.”
“The earlier we get out here, the better the fix is. So see something, go ahead and call.”

[0:04] - So we get main breaks
throughout the entire year.
[0:07] They're most common in the winter
[0:08] when the frost is going in the ground,
[0:10] the ground's moving, pipes are moving,
[0:11] that's when they get stressed.
[0:13] So in the summertime,
[0:14] they're actually pretty straightforward.
[0:16] Water comes up where the
break is most of the time.
[0:18] New road surfaces, things
like that can push the water.
[0:21] Frost in the winter pushes the water,
[0:23] so it gets a lot harder.
[0:24] So when we show up, it's
really kind of what we see.
[0:28] This one was from a city main,
[0:29] so it's our responsibility to fix it.
[0:32] So at that point, we throttle it down.
[0:33] That just prevents property damage,
[0:35] road surfaces from being impacted,
[0:38] and then we have to get
emergency locate tickets.
[0:40] So we have to get other providers out here
[0:42] to mark their utilities.
[0:44] We don't want to hit gas,
communication, things like that.
[0:47] So we kind of know what we're
dealing with at that point.
[0:49] If you have a clean hole, which means
[0:51] there's no other utilities or obstructions
[0:52] that we have to deal with,
[0:53] then we can use the excavator,
which is behind me here.
[0:56] It's our fastest means of
digging up the water main.
[0:59] So we'll put on a jackhammer
and we'll take the blacktop
[1:02] or concrete, whatever
our hard surface is, off.
[1:04] Then at that point, we'll either dig,
[1:06] if there's no frost, with the bucket.
[1:08] If there is frost in the ground,
[1:09] then we'll keep the jackhammer on
[1:11] because that ground's hard
and we gotta get it busted up.
[1:13] So at that point, we get down to our pipe
[1:15] and then we have a dig box,
which is for operator safety,
[1:19] so that box holds all the soils back.
[1:21] If there's a cave-in, it protects you.
[1:23] We'll take a stainless steel band
[1:25] and it's rubber lined on the inside
[1:27] and it just clamps down
[1:28] and seals the rubber around the crack.
[1:30] And that's actually what makes
the seal to stop the leak.
[1:32] So then at that point we
can charge the water main,
[1:35] check the leaks, make sure
we did get a good seal
[1:37] and purge any air that might've
gotten in the water main out
[1:41] so that we're not pushing that
[1:42] into homes and causing problems.
[1:44] And at that point, as
long as everything's good,
[1:46] we start backfilling with fresh conbit
[1:48] and then we have a
tamper on the excavator,
[1:50] so we get good road compaction right away.
[1:52] In the winter, we do do
a temporary road patch.
[1:54] We'll come back in the spring,
we'll take that back out
[1:57] and then do our permanent patch.
[1:59] Feel free to call.
[2:00] Whatever you see, give us a call.
[2:02] We're staffed 7:00 AM till 11
in the evening on weekdays,
[2:07] and we're still on call after
that, so somebody can be here.
[2:10] So we just want to get on it early.
[2:11] The earlier we get out
here, the better the fix is.
[2:13] So see something, go ahead and call.
