Underground Utilities

Expert underground utility installation and reconstruction services.

Laying the Groundwork for Success

The toughest work on any project happens underground. Wagner’s expert utility crews install miles of water, sewer, and storm systems with precision and efficiency, even in the most unpredictable ground conditions.

From municipal upgrades to private and commercial developments, our utility crews bring the planning, experience, and adaptability to keep underground systems operating safely and securely.

Safe, Precise & Reliable

Wagner’s underground utility crews are the backbone of every project. They work strategically to keep projects moving forward while maintaining strict safety protocol, regardless of the environment.

From navigating congested municipal streets to running large-diameter pipe in remote locations, our crews work with precision to ensure underground systems are installed correctly the first time.

Wagner’s Underground Approach

Proactive, Not Reactive

Underground utilities support every phase of construction, so mistakes here ripple across the entire project. We anticipate conflicts early, coordinating excavation and installation to keep future work on schedule and risk-free.

Safe, Never Complacent

As experienced utility contractors, we know the stakes of a missed 811 call, preventable cave-in, or utility strike. Safety is never assumed — it’s actively enforced.

Experienced, Not Overconfident

Seventy years of field-earned knowledge gives us confidence, but not tunnel vision. We approach each project with fresh focus to prevent oversights and deliver right the first time.

Featured Wagner Projects

Flood Hazard Mitigation Project

The scope of the project was to construct a reinforced concrete floodwall and reroute underground utilities around the existing water treatment plant to protect the plant from flood conditions.
