Comprehensive Underground Infrastructure Expertise
When utility infrastructure needs to go in fast, hold up under pressure and disrupt as little as possible, you want an underground utility contractor that’s done it for decades. That’s exactly what we bring to your project. Zachry self-performs wet and dry utility systems for municipal networks, transportation corridors, aviation facilities, industrial campuses and site-development projects. Our teams bring the people, equipment and field experience needed to install underground infrastructure while coordinating with the construction taking place around and above it.
We manage the entire process, with a single delivery team that coordinates dry utilities, water, wastewater and stormwater with the broader construction sequence. That coordination helps identify conflicts earlier and gives the project team clearer control over installation quality and schedule. That means more dependable execution, reduced risk and greater certainty from start to finish.
Full-Service Utility Work That Fits Your Project Goals
When power and cable systems have to go in clean and stay reliable, you want a utility installation contractor who has done it for decades. Zachry Underground and Utility Services (ZUUS) self-performs trenching and excavation, underground conduit and duct bank installation, electrical cable installation, transformer pads, transformers and risers, communications and fiber conduit systems, street-lighting infrastructure, gas infrastructure, utility upgrades and residential rehabilitation. Our crews support both new development and modernization work while coordinating construction around existing operations and neighboring communities.
Water & Wastewater Systems
When you need dependable water and sewer systems, having a utility infrastructure contractor who knows how to upgrade, modernize or install them right is critical. Zachry constructs municipal water-distribution and wastewater-collection systems, including gravity sewer, force mains and lift stations while coordinating installation with earthwork, paving and adjacent infrastructure. Our integrated approach improves constructability, reduces conflicts between project phases and supports safe, efficient project delivery. The result: a smoother installation process, stronger coordination and fewer interruptions to the work happening around it.
Stormwater Systems
Zachry installs storm sewer systems, box culverts, drainage networks and outfalls to convey runoff during construction and support permanent site drainage. Coordination with our Heavy + Highway, Water Infrastructure and Civil Sitework teams integrates drainage work into the overall construction sequence and reduces conflicts with adjacent scopes.
Zachry coordinates and executes utility relocations, conflict resolution, protection of existing utilities and multi-utility sequencing before and during construction. For highway, airport, industrial and municipal projects, our teams coordinate with owners, utilities and adjacent contractors to maintain service and keep planned work accessible.
