St. Charles County, MO

Before a contractor sets footings, bores under a road or trenches for new service in St. Peters, someone needs to know exactly where the existing lines are. Our hydrovac trucks dig with water and suction, exposing buried utilities so they can be measured and protected instead of found by accident. Our work there is mostly commercial and utility: site development, road and intersection projects, new service connections and utility crews who need lines verified before they excavate.

## Local conditions in St. Peters

St. Peters is crowded underground along its main corridors. I-70, Highway 79, Highway 94 and Mid Rivers Mall Drive carry water mains, gas lines, power and fiber that have been added to as the city filled in. Potholing at each crossing gives a crew the true depth and position of every line in the way.

Low ground near Dardenne Creek and Spencer Creek can be soft and wet, while upland sites are firm clay. Hydrovac works in both: it keeps excavation tight in soft soil and breaks up sticky clay that bogs down hand digging, all without swinging a bucket near a live line. The vacuumed material is held in the truck, which matters on tight commercial lots where there's nowhere to pile spoils.

Start with a Missouri 811 one-call ticket so the lines get marked. We then daylight at the marks, slot trench a planned route to catch anything unmarked, or dig pole and bollard holes in tight spaces near existing utilities. We can also clean out catch basins, inlets and utility vaults on commercial sites, since the same truck that digs also vacuums.

## Frequently asked questions

### Do I need an 811 ticket if you're digging with hydrovac?

Yes. Call Missouri 811 first. Hydrovac is how lines are safely exposed and verified after they're marked.

### Can hydrovac dig pole or bollard holes near existing lines?

Yes. It's a common use, because the hole stays tight and nothing is struck while digging.

### Does wet ground near the creeks slow you down?

Soil conditions affect production, but hydrovac handles wet soil well. The estimator accounts for soil type, and your written quote confirms it.
