Aransas Pass Water/Wastewater System Expansion

Location San Patricio County, TX

Client City of Aransas Pass

As part of the federally funded American Rescue Plan, the City of Aransas Pass is installing several segments of water and gravity wastewater mains. The project expands the City’s water and wastewater system to provide service to areas of Aransas Pass that previously did not have service.

The project consists of three construction packages totaling 5,600 linear feet of 6-inch water main and 5,900 linear feet of 8- and 12-inch gravity wastewater main across several locations. The project includes pipeline design, bid, and construction phase services for the water and wastewater system expansion. During preliminary engineering, we performed limited topographic survey in the feasibility stage to ensure that functional gravity wastewater mains could be installed, given the flat terrain. We also performed subsurface utility exploration to locate existing utilities and ensure they did not conflict with the proposed design.

Due to budget constraints, our team worked with the City to include additive alternatives in the bid package, such as construction of the water main in Package 1 and the pavement overlay in Package 2, so that the City could evaluate whether it was more cost effective for the work to be performed by the contractor or done in-house. The project required proactive communication from our team where technical decisions needed to be made quickly. During the construction phase of Package 1, our team stayed in near-constant contact with the City and the contractor to ensure the design was implemented correctly. Coordination with the GLO Federal Consistency Coordinator also ensured there were no negative impacts to the Texas Coastal Management Program, and we coordinated with the Texas Historical Commission to confirm no archaeological impacts.

The expansion brings 99 additional sewer services and 106 additional water services.
