The Founding Story
A father, a water bill, and a problem that wouldn't go away.
Calvin's daughter started getting recurring chest tightness in the shower. The pediatrician traced it back to chlorine reactivity from the city water. The family was already paying a municipal bill — and still buying bottled water for cooking.
He installed a whole-house system at his own home. The chest tightness stopped within days. The bottled-water habit ended that week. Calvin spent the next year studying media chemistry, sizing math, and Florida-specific well treatment — then started installing for neighbors who were dealing with the same thing.
Today Intiwater serves twelve cities across Southwest Florida from a single Cape Coral base. Every system is sized to a 5-test panel taken at the customer's actual tap. Every install is documented, numbered, and filed. Every service call for the next fifteen years is included — no prorated math, no fine print.
Three principles
- I
Family-first thinking
Calvin started this for his own household. That perspective shapes every install — sizing, media choice, warranty terms, response time.
- II
WQA-member discipline
Card-carrying members of the Water Quality Association. Continuing education, peer-reviewed standards, real accountability.
- III
Six-person bench, no call centers
Hand-picked technicians on a small team. You talk to the person who'll install your system — not a national booking line.
