Water Project Expertise That Runs Deep
Reliable water infrastructure starts with a contractor that delivers confidence. It takes a team that understands the responsibility behind every system, every connection and every deadline. Zachry builds and rehabilitates large-scale water infrastructure for communities, industries and regional systems. Our work includes dams, reservoirs, raw water conveyance, pumping facilities and treatment plants, supported by more than a century of heavy civil experience.
Zachry self-performs major scopes with our experienced crews and specialized equipment, ensuring intended progress with our advanced project control systems. This approach helps our teams coordinate interfaces and respond to changing conditions while maintaining safety, quality and schedule requirements. We support water authorities, river authorities, federal agencies and industrial users with the construction resources needed for complex water infrastructure.
Expertise Across the Water Infrastructure Lifecycle
You need treatment and processing systems to perform and stay in compliance every day. Treatment facilities bring together civil construction, complex process systems and exacting operational requirements. Zachry delivers drinking water treatment plants, wastewater treatment plants, water reuse facilities and other process facilities, with capabilities spanning new construction, upgrades and expansions. Our teams understand the coordination required among structures, mechanical piping, process equipment, electrical systems and existing plant operations. That experience helps you expand capacity, modernize aging facilities and meet evolving water needs while protecting ongoing operations.
Water storage infrastructure must perform reliably for decades. Zachry builds and rehabilitates dams, reservoirs, storage tanks and flood control structures designed for long-term performance under demanding conditions. Our experience also includes complex gate installation and rehabilitation, where careful planning, sequencing and execution are essential to working within existing water systems. From new construction to improvements on critical operating assets, we bring the heavy civil expertise to build infrastructure you can depend on.
Every connection matters when water needs to stay in motion. Zachry constructs the systems that transfer water between rivers, reservoirs, treatment facilities and industrial users, including raw water conveyance, water transfer systems, intake and pumping facilities, canals and channels. By coordinating major civil, structural and mechanical scopes in the field, our teams can address the complex interfaces and operating constraints that define large-scale conveyance projects.

Managing water also means preparing for what happens when there is too much of it. Zachry constructs and rehabilitates levees, spillways, outlet works, flood mitigation structures and stream restoration projects that help protect communities, infrastructure and natural systems. These projects demand an understanding of earthwork, hydraulic structures, environmental constraints and construction in and around active waterways. We bring those disciplines together in the field, giving you an experienced partner for infrastructure built to withstand changing conditions and perform when it matters most.

LANE CITY DAM REHABILITATION
The Lane City Dam Hurricane Harvey Rehabilitation and Recovery Project is restoring and strengthening the dam and its surrounding banks to improve long-term resilience following damage caused by Hurricane Harvey. Zachry’s work includes installing new sheet piling and grout bags along the west bank and existing dam, modifying and extending sheet piling on the east bank, and stabilizing eroded slopes with excavation, rock riprap, and other protective measures. The project also includes replacement of the gate hydraulic cylinder and construction of a new control building with upgraded electrical systems. To support construction across the site, Zachry constructed a temporary trestle…

PALMETTO BEND DAM REMEDIATION
Zachry is rehabilitating Palmetto Bend Dam for the Lavaca-Navidad River Authority in Jackson County, Texas. The project is designed to enhance embankment stability and long-term dam safety by reducing downstream water pressure and mitigating conditions that could contribute to seepage and piping. The centerpiece of the rehabilitation is approximately 1,550 linear feet of permanent cutoff wall constructed along the dam crest, including an additional test section used to evaluate performance and determine whether further extension is needed. Zachry’s work also includes improvements within the East Drain Ditch, where the team will construct a boil closure to replace the existing sand…
