Zachry Construction Corporation is advancing work on the Central Regional Wastewater System Chlorine and Sulfur Dioxide Containment Building project in Dallas. The Trinity River Authority of Texas authorized the contract at approximately $108.5 million, according to TRA board materials dated December 3, 2025. The project is expected to wrap in Q4 2029.
Zachry is serving as prime contractor on the multi-year effort. Scope covers demolition of existing equipment and structures, modifications to existing facilities, and construction of a new chlorine and sulfur dioxide containment building and a supplemental chlorine storage building.
The team is also delivering pump stations, sitework, grading, paving, stormwater drainage, roadways, chemical solution piping, plant water piping, drain and stormwater piping, natural gas piping, and electrical and instrumentation systems.
The work is designed to modernize critical wastewater infrastructure at the CRWS treatment plant and improve containment, utility systems, and long-term operational reliability. Tyler Farella, vice president at Zachry Construction, described the project as an example of the complex civil and water work the company is built to deliver.
This project fits into a broader strategic move into the water sector for Zachry. The San Antonio-based contractor acquired water infrastructure firm Crescent Constructors in the fall of 2025 and on April 21, 2026 named Travis Mross as its next president, with water work central to that announcement.

TheJobWalk Thoughts
A $108.5 million, multi-year wastewater project with this scope has real subcontractor volume behind it. Electrical, mechanical, piping, civil, and instrumentation trades are all in play based on what is outlined. Subs and suppliers working the Dallas market should be tracking this one now, because procurement windows on long-duration public infrastructure jobs stretch out over time and getting in front of the prime early is what positions you for the work.
Zachry's acquisition of Crescent Constructors and the Mross appointment are two moves in quick succession that point the same direction. Water infrastructure is a priority lane for this company, not a peripheral one. For sales teams calling on Zachry, that context matters when walking in the door.
