Healthcare industry case study
St. Luke’s Health System
Problem: St. Luke’s Health System faced the critical challenge of ensuring uninterrupted access to high-quality water essential for patient care and emergency situations. The hospital required a water system with continuous uptime, built-in redundancy, and reliable performance to support its complex healthcare environment. Additionally, the system needed 24/7 support and an emergency water supply agreement to maintain operational resilience during unexpected crises.

Hospitality case study
The Maxwell, Apartment Complex | San Antonio, Texas
Problem: A multi-unit apartment complex faced recurring boiler failures due to hard water in the hot water system, leading to high maintenance costs, tenant complaints, and system inefficiencies caused by cross-connection leakage and a complex recirculating pump setup.
Solution: The complex partnered with Culligan to install a CTM Water Softener for commercial-scale softening and a HOT Water Portable Exchange Softener to treat return lines, effectively addressing hardness in the hot water recirculation system.
Results: Culligan’s solution eliminated hardness in the return line, protecting the boilers and restoring consistent hot water. With cross-connection repairs underway and improved water quality, the complex saw fewer complaints, lower maintenance costs, and greater tenant satisfaction.

Education industry case study
(Confidential) Local Independent School District | San Antonio, Texas
Problem: A school district faced an urgent sanitation issue when new red lunch trays developed a white film after dishwashing, making them look dirty. This raised hygiene concerns, required manual scrubbing, affected multiple schools, and led to increased labor and costs. The district turned to Culligan for a fast and effective solution.
Solution: Culligan installed a hot water portable exchange softener to treat hard water in the dish machines, effectively eliminating the minerals causing the white film on trays.
Results: Culligan’s solution delivered immediate improvements, including clean, residue-free trays, better dish machine performance, reduced detergent costs, and simplified maintenance with a salt-free system.

Car wash case study
Soft Suds Car Wash, Midland & Odessa, Texas
Problem: Soft Suds Car Wash faced frequent system failures and costly downtime because their franchise-recommended water treatment system couldn’t handle the extremely poor water quality in West Texas. This led to significant losses in operational efficiency and revenue.
Solution: To resolve the water quality issues, Soft Suds partnered with Culligan, who provided a custom-engineered solution that included high-capacity softeners, carbon tanks for chlorine removal, and multiple stage-specific reverse osmosis systems. A final RO system was also added to recycle rinse water, improving water efficiency and reducing waste.
Results: Culligan’s solution delivered major improvements for Soft Suds Car Wash, including elimination of downtime, dramatically improved water quality (TDS down to 15 ppm, and hardness and chlorine at non-detectable levels), reduced chemical use, and optimized water usage through recycling. These results led to greater efficiency, cost savings, and operational stability.
