Underground Utilities: Water, Sewer and Storm Drain
Our underground crews install the systems that keep a town running, from water and sewer to storm drainage and conduit.
We've installed water and sewer transmission lines for decades. Today that includes concrete pipe and box culverts, stormwater chamber systems, and the trenching, bedding and backfill around them.
Projects
Also on our list: City Creek Pump Station/Pipeline, Springdale Sewer Lagoons, 300 East Drainage.
How it gets built
How a Sewer Line Goes In
Most of a sewer job happens underground and out of sight. Here's the street cut open along the line.
Survey and Locate
We stake the line and grade, and every utility in the way gets marked and potholed before a machine digs.
Trench and Shoring
We saw-cut the road and dig the trench to grade. A steel trench box goes in so the crew works inside safe walls.
Bedding
Clean rock goes in the bottom and gets shaped to grade, so the pipe sits on an even, solid bed.
Lay Pipe and Manholes
Precast manholes are set, and the pipe is laid between them on a steady fall so it drains by gravity. Every joint gets checked.
Backfill and Compact
We backfill in thin lifts and compact each one, carefully around the pipe first. That keeps the road from settling later.
Test
Each run is plugged and air tested for leaks, then a camera goes through to check every joint.
Restore the Road
Road base goes back, the trench gets an asphalt patch, and the lids are set flush with the street. Then we restripe.
