Commercial & Industrial Water Treatment
Commercial & Industrial
Softening, filtration, deionization, reverse osmosis, and custom-engineered membrane systems — sized to your flow rates, your contaminants, and your uptime requirements.
Commercial water treatment is not residential equipment scaled up. Boilers, cooling towers, dish machines, ice makers, autoclaves, RO/DI labs, beverage lines, and process loops each have specific water chemistry windows — and missing them costs you in scale, downtime, warranty disputes, energy, and product quality. Our commercial team designs around those windows. We start with a site survey and a defensible water analysis, then specify equipment, install it cleanly, and keep it running with a service plan that matches the criticality of your operation. Commercial service is available nationwide — single sites, regional portfolios, and multi-site national accounts, all under one program.
What We Solve
- Hardness and scale destroying boilers, water heaters, dish machines, and ice machines
- Iron, manganese, sulfur, TDS, silica, and chloramine impacts on process water
- RO/DI water for laboratories, electronics, optics, and pharmaceutical applications
- High-flow filtration and disinfection for food, beverage, and bottling operations
- Compliance pressure on lead, PFAS, disinfection by-products, and Legionella risk
- Multi-site water programs with consistent specs across every location

Why Operators Choose Culligan
Culligan has been engineering commercial water systems for more than 85 years. That depth shows up in three places: equipment overbuilt for the duty cycle of a business, the largest commercial water service network in North America so we can put a technician on your site in almost any U.S. market, and lab-backed analytics that turn a water problem into a specification.
Frequently Asked Questions
Do you provide commercial water treatment nationwide?
Yes. We deliver commercial water treatment — softening, filtration, RO, DI, membrane systems, salt delivery, and service — to facilities across all 50 states. Single sites, regional portfolios, and multi-site national accounts are all supported under one program with one point of contact.
How fast can you get someone on site?
Same-week site surveys are standard for new commercial accounts. For contracted multi-site customers we operate to defined SLAs with same-day response targets for critical-loop calls, anywhere in the country.
Do you handle equipment we did not install?
Yes. We routinely take over service on softeners, RO skids, and DI exchange programs originally installed by other vendors. We will audit the existing equipment, document any gaps, and quote service or replacement against your actual water chemistry and flow profile.
Can you write a water-quality spec for our facility or process?
Yes. Send us your incoming water analysis, your equipment manufacturer water requirements, and your peak and average flow. We will return a treatment train recommendation and a target effluent spec you can hold us accountable to.
