Gainey’s Concrete offers advanced packaged extended-aeration wastewater treatment plants designed to deliver effective, scalable solutions for communities and large-scale developments. Serving projects from as few as five homes to systems up to 1 million gpd, Gainey’s plants are manufactured in Louisiana and shipped across the southeastern U.S., meeting rigorous standards including TDEC, LDH, LDEQ, and Ten States Standards. Built with 5,000 psi precast concrete, Gainey’s systems are engineered for long-term performance with a service life of 50 to 100 years.
By enhancing traditional extended aeration processes, Gainey’s systems can achieve advanced treatment levels as low as 5 BOD₅ / 5 TSS / 2 NH₃-N with tertiary filtration, while maintaining a small footprint and low energy demand. Designed for real-world conditions, the plants use off-the-shelf components for easier maintenance, offer a low life cycle cost, and can be installed in phases to support future growth.
