Best known for our ­flexible, customized wastewater treatment solutions, AUC offers temporary, interim or permanent plants based on individual customer needs. We thrive in situations where moratoriums are placed in development due to lack of capacity, when developers wish to build on land without existing infrastructure and when existing facilities need to be replaced.

Our total wastewater treatment solution includes a leasing program that enables financial fl­exibility with a variety of short and long-term lease arrangements as well as the option to purchase. Coupled with our proven modular plant design for phased growth, customers can expand capacity when needed at the most affordable rate.

With over 1,500 installations since 1970, the AUC Group total solution is a forward-thinking alternative to traditionally slow-moving delivery methods.

In 2018, AUC became the wastewater division for Seven Seas Water, a multinational developer, owner and operator of water and wastewater treatment plants and businesses. Pioneers of the Water-as-a-Service® approach, Seven Seas Water provides customers with all-inclusive custom desalination, advanced water and wastewater treatment, and water reuse services, at a guaranteed cost, quantity and quality.
