In 2016 the EPA ruled on The Toxic Substances Control Act. This ruling was about prioritizing, evaluating, and regulating chemicals and included a requirement for industry reporting of chemicals manufactured or processed in the U.S. over the past 10 years. Two of the chemicals that were listed under this act were PFAS and PFOS. In August of 2018, the Town of Marana Council made a unanimous decision to pursue the design and construction of a water treatment facility for the two impacted systems in Marana Water found to contain unregulated compounds (PFOS & 1,4-dioxane).

In 2018 the Town of Marana put out a CMAR project with a construction value of $14M to design and build two treatment campuses at the existing wells, the Picture Rocks and Airline Lambert Treatment Campuses, to treat PFAS through GAC (Granular Activated Carbon). According to Archer Western, “The Airline Lambert and Picture Rocks Water Treatment Campuses are among only a handful of full-scale municipal drinking water treatment facilities in the U.S. employing a UV-hydrogen peroxide advanced oxidation process (UV AOP) for 1,4-dioxane destruction, followed by GAC for both excess peroxide quenching via a catalytic reaction and PFAS adsorption.”

Victaulic worked with the stakeholders of the project to optimize the piping throughout the Picture Rocks Treatment Campus facilities. Victaulic delivered a prefabricated design to simplify the installation and accommodate the multiple jobsites and minimal laydown yards. Victaulic’s solutions were utilized on the Picture Rock Campus on the GAC Contractors, UV AOP Building, bag filters, and desanders applications. Throughout these applications, the following Victaulic solutions were installed:

• Style W77 AGS Flexible Couplings
• AGS Grooved Fittings
• Style 107N QuickVic™ Rigid Couplings
• Style 177N QuickVic™ Flexible Couplings
• Style 77 Flexible Couplings
• Style 257C Dynamic Movement Joints
• Victaulic Series 761 Vic-300™ Masterseal™ Butterfly Valves

Victaulic delivered a repeatable, reliable, and dependable design to the Town of Marana that accommodates their need to expand their city’s infrastructure requirements. The Town of Marana has significantly benefited from utilizing Victaulic’s solutions for the water market and is now looking to standardize around Victaulic on not only their future 26 sites but in all applications that support their infrastructure needs.
