#  Axius Water Brings Solutions Together for STOPPING NUTRIENT POLLUTION at WEFTEC 2026 

Sep 28, 2026  [News & Press](https://microc.com/resources/news) 

**NEW ORLEANS, LA USA (September 28, 2026):**

Axius Water, now part of Oldcastle Infrastructure™, A CRH company, will showcase its industry-leading water and wastewater treatment solutions at **WEFTEC 2026** in **Booths 7425**, **7839,** and **5938**. Learn how Axius Water can now deliver a broader range of integrated water infrastructure solutions across municipal and industrial systems to help stop nutrient pollution. WEFTEC 2026 takes place **September 28-30, 2026,** at the Ernest N. Morial Convention Center in New Orleans.

Nutrient pollution continues to challenge communities across North America, as utilities face increasingly stringent discharge requirements, aging infrastructure, and the need for cost-effective treatment solutions. The challenges are different for large vs. small communities but all are equally complex.

[EPA's 2022 Clean Watersheds Needs Survey (CWNS)](https://sdwis.epa.gov/ords/sfdw_pub/r/sfdw/cwns_pub/wastewater-dashboard) data indicates that more than 80% of publicly owned treatment plants in the United States serve communities with flows of less than 5 MGD. These facilities often must balance regulatory demands with limited staff and resources, creating a need for practical, reliable treatment solutions that are easy to operate and maintain.

According to **CEO Chris McIntire**, "At Axius Water, we help utilities and communities of all sizes solve complex water and wastewater challenges through proven technologies, process expertise, and practical solutions that deliver measurable results. We're especially proud to help smaller communities achieve their goals through expert guidance, dependable solutions, and approaches that make the most of existing infrastructure. And we're excited to enter this next chapter as part of Oldcastle Infrastructure, whose resources and reach will allow us to bring our solutions to even more communities facing wastewater challenges."
