AUC provides both field erected, concentric circle wastewater treatment plants as well as flexible, modular plants that are designed to expand as needs arise. AUC has successfully completed more than 1,500 wastewater treatment plants in our history, ranging in capacity from 5,000 gallons per day to over 1,500,000 gallons per day.

Our lease plant program is an extremely cost effective solution relative to traditional wastewater treatment plant options, costing only a small fraction of the required capital outlay. AUC will install, lease and expand facilities designed specifically to meet your wastewater treatment plant needs. We offer a variety of short and long term leasing options as well as a lease with the option to purchase.

While AUC has historically focused on the Texas wastewater treatment market, the company has completed projects in other states including Alabama, Arkansas, Arizona, California, Colorado, Indiana, Louisiana, Missouri, New Mexico, and Oklahoma. In addition, we have completed projects in Mexico and El Salvador. AUC is capable of providing wastewater treatment plant solution services in all 50 States as well as internationally. With our available leasing options, we are able to offer more cost-efficient wastewater solutions in every state and municipality where we build.

AUC Group has built a solid reputation of dependable, quality work with a commitment to our customers and the environment. Although our facilities have a useful life of more than 20 years, they are modular and scalable “on demand”. Our custom-designed wastewater treatment plant solutions are ready to expand as your development grows.
