Better water. Better price.
Right here at home.
Coastal Water Systems is a locally owned water filtration company based in St. Augustine. Your neighbors, not a national chain.
Our story
Plumbing first, sales second
We live, work and raise our families in the same communities we serve, and we deal with the same water you do every day.
That's why we know firsthand the water quality challenges local homeowners and businesses face, and why we take the time to understand your property before we recommend anything.
Built on 30+ years of plumbing
Coastal Water Systems was founded on a simple belief: water treatment should be designed, installed and serviced by experienced professionals, not salespeople. The connections, drains and pressure details get handled properly, never improvised.
One local company, start to finish
Every system we provide is carefully built, professionally installed and fully supported by the same local company.
- No subcontractors
- No out-of-town service crews
- No disappearing sales representatives
When you call, you're working directly with local experts who stand behind their work and their reputation.
Homes and businesses
We install filtration for residential and commercial customers alike. Whether it's protecting your plumbing, improving drinking water or providing cleaner water for your business, the goal stays the same: the right system at a fair price, with real local service.

How we work
What you can expect from us
Experience behind the install
30+ years of plumbing work means connections, drains and pressure details are handled properly.
No pressure, no gimmicks
We explain your options, tell you what we'd do and let you decide. No scare tactics, no one-day-only pricing.
Genuinely local
When you need filters or service, you're calling a neighbor, not a national queue.
Better water, better price
Independent means lower overhead, and we'd rather pass that along than pad a quote.
