Water treatment and filtration solutions for residential and commercial customers
Culligan operates a 10,000+-person water treatment business across residential, commercial, and industrial segments, supported by a manufacturing and field-service footprint. The tech stack reveals a heavy operational backbone (IFS, SAP, Salesforce) paired with industrial control systems (Allen-Bradley, PLC, HMI, Modbus, BACnet) — typical of asset-intensive manufacturing with distributed field operations. Active hiring in ops and engineering, combined with projects around branch efficiency automation and lean manufacturing, signals ongoing effort to tighten margins and reduce field-service friction.
Notable leadership hires: Customer Service Director, Head of Marketing, Talent Acquisition Director
Culligan provides water softening, filtration, and treatment systems for homes, commercial buildings, and industrial facilities, alongside bottled and bottle-free water cooler services. Founded in 1936, the company operates at scale across the United States, Portugal, United Arab Emirates, Chile, and Paraguay. The business model combines product sales, recurring service contracts (field technicians, maintenance), and consumables (replacement filters, bottled water). Current focus areas include expanding industrial solutions for data center and specialized water treatment applications, optimizing field-service logistics, and driving operational efficiency through automation and lean practices.
Culligan runs IFS and SAP for enterprise resource planning, Salesforce for customer and sales operations, along with industrial control systems including Allen-Bradley PLCs, Modbus, BACnet, and Profibus. They use Microsoft Office and Power BI for analytics, and recently adopted LIMS for laboratory and quality management.
Culligan is headquartered in Rosemont, Illinois, and employs over 10,000 people globally. The company is privately held and was founded in 1936.
