What Maguire Iron, Inc. does
Maguire Iron, Inc. is a privately held specialty construction company headquartered in Sioux Falls, South Dakota, that designs, engineers, fabricates, constructs, and maintains elevated water storage tanks and towers for municipal water utilities, communities, and industrial customers across 33 U.S. states. The company operates a hybrid business model combining new construction project work — typically delivered through design-bid-build or collaborative build approaches — with recurring maintenance services (painting, sandblasting, containment, inspections, and emergency repair) and a smaller transactional e-commerce parts business for replacement tank components. With a workforce of 100+ employees and over a century of operating history, Maguire serves thousands of communities and competes in an elevated water storage tank market projected to reach $8.48 billion by 2030, driven by aging infrastructure replacement and regulatory compliance needs.
The company's go-to-market is built on direct field sales with dedicated local representatives in each of its 33 state service areas, including a granular four-region Texas presence. Pricing is quote-based and project-specific, structured as multi-year maintenance contracts following initial construction. Maguire has invested in content-driven demand generation, including a monthly podcast (with episodes ongoing into 2026) and a webinar series aimed at water system professionals. The company has adopted corrosion-resistant materials and smart monitoring systems within its tank construction and maintenance offerings, signaling gradual modernization of the underlying technology stack. Maguire's May 2026 hosting of an SBA roundtable with regional manufacturers and policymakers reinforces its positioning as a recognized small-business champion in U.S. water infrastructure, while its privately held, non-PE-backed ownership structure suggests organic rather than acquisitive growth as the dominant expansion mode.
