Professional Utility Trenching for Every Project
Every building needs utilities—water, sewer, electricity, gas, internet. Getting those lines from the street or meter to your structure requires careful utility trenching that meets depth requirements, avoids existing utilities, and protects the lines once installed. Our utility trenching services in Utah handle the excavation side so your plumbers, electricians, and utility companies can focus on installation.
As experienced trenching contractors in Southern Utah, we understand the soil conditions that vary across Washington County—from sandy soils near the Virgin River to rocky hillsides in St George's premium communities. We adjust our approach and equipment based on your specific site conditions.
Water & Sewer
Water service lines, sewer connections, septic trenches, and irrigation mains.
Electrical & Comm
Underground electrical conduit, fiber optic, and communication line trenching.
Gas Lines
Natural gas and propane line trenching to code depth with proper bedding.

Blue Stakes & Utility Locating
Before any trenching begins, we coordinate with Blue Stakes (call 811) to mark existing underground utilities. This critical step prevents dangerous—and expensive—accidents. In developed areas of St George, Washington, and Hurricane, there are often multiple utility lines running through easements. We respect these markings and hand-dig as needed when approaching marked lines.
