A long-term wastewater infrastructure upgrade is underway in Dallas as Zachry Construction continues work on a major treatment facility modernization project for the Trinity River Authority of Texas. The effort is focused on improving operational reliability, safety systems, and utility infrastructure at the Central Regional Wastewater System site.

The project includes demolition of existing structures and equipment, followed by the construction of new facilities and system upgrades designed to support ongoing treatment operations. Key components of the work involve new containment infrastructure for treatment chemicals, additional storage capacity, and expanded support systems across the plant.
As the prime contractor, Zachry Construction is overseeing a broad scope of work that spans site development activities, grading, paving, stormwater management systems, roadway improvements, and extensive utility installations. These utilities include chemical solution piping, plant water distribution, drainage infrastructure, natural gas lines, and integrated electrical and instrumentation systems.
The project is centered on improving how the facility manages critical treatment processes while maintaining safe and continuous operations. Upgrades to containment and storage systems are intended to enhance long-term reliability and reduce operational risk in a facility that serves a growing regional population.
Large-scale wastewater projects of this type typically require extended execution timelines due to the complexity of maintaining live plant operations during construction. The current schedule anticipates completion in the fourth quarter of 2029, reflecting the phased nature of the work and the coordination required between construction activities and ongoing treatment functions.
From a construction industry perspective, the project reflects sustained investment in municipal water infrastructure across major metropolitan regions. Population growth, aging treatment systems, and regulatory requirements continue to drive demand for facility upgrades and expansions, particularly in large Texas metro areas.
For owners and contractors, projects like this highlight the increasing importance of integrated delivery approaches that combine civil, mechanical, and electrical scopes under tightly controlled sequencing. They also underscore the need for experienced teams capable of working within active industrial environments where downtime is not an option.
Once complete, the upgraded facility is expected to strengthen long-term wastewater treatment capacity and improve operational resilience for the region’s water infrastructure network.
