Xerxes

What Xerxes does

Xerxes Corporation, founded in 1979 and headquartered in Minneapolis, Minnesota, is a North American manufacturer of corrosion-resistant fiberglass underground storage tanks and stormwater management products. The company sells a broad engineered-product portfolio organized around three solution families: Tank Solutions (fuel tanks, DEF tanks, water and wastewater tanks, grease interceptors, oil-water separators, flare knockout tanks, anchoring, containment sumps, and the Truchek hydrostatic leak-detection system); the HydroChain stormwater line (S-29B, S-22, C-10, and M-6 chambers, vaults, Aquamod crate modules, and water-quality components such as the Main Header Row, Vortex Filter, and Prime Separator); and the Phoenix System tank upgrade retrofit. Underlying technology centers on proprietary composites: double-wall fiberglass construction, Parabeam 3D glass fabric bonding for interstitial space and structural reinforcement, and UL-listed resins for corrosive liquids and biofuels. Founded to displace corroding steel underground tanks, Xerxes pioneered the industry's first UL-listed double-wall fiberglass tank in 1984, the first wet-interstice double-wall tank in 1989, the Truchek monitoring system in 1993, the 3D glass-fabric bonding technology in 2002, and the world's first long-fiber thermoplastic stormwater chamber in 2025.

The company makes money primarily through direct hardware sales of custom-engineered tanks and stormwater systems, priced project-by-project via quote-based sales, with a free digital tooling layer (XerxesConnect tracking and design calculators) tied to customer engagement. Go-to-market is enterprise field sales through a North American network of representatives organized by geography and market segment (fuel, water/wastewater, stormwater). Customer segments span fuel retailers and major oil companies, mission-critical facilities (hospitals, data centers, airports), municipalities, real estate developers, industrial sites, and government/infrastructure customers. Products are manufactured at seven facilities across the U.S. (Minneapolis, Seguin TX, Tipton IA, Williamsport MD, Blythewood SC, plus a 2025-added Rockwall TX chamber plant) and Canada (Edmonton AB, Drummondville QC), and are carried by a broad certification stack (UL 1316, NSF/ANSI 61, NFPA, IAPMO, ASTM, EPA, NJCAT) that supports specification lock-in.

Xerxes is a wholly-owned subsidiary and key brand of Mattr (formerly Shawcor), which acquired the company in 2019 and rebranded from Shawcor to Mattr in 2023 as a focused critical infrastructure materials company. The firm has shipped more than 225,000 composite fuel and water tanks across North America and installed 100,000+ Truchek hydrostatic monitoring systems over 30 years. Recent strategic activity includes the 2021 launch of the HydroChain stormwater product line, the 2024 opening of a seventh manufacturing facility, the 2025 acquisition of Triton Stormwater Solutions, and the 2025 introduction of the long-fiber thermoplastic S-29B chamber.
