Every drop matters.
Horizon Water Co installs high-performance water treatment equipment engineered for Rhode Island's water — hard, chlorinated city supply and untreated well water alike. Every system below is one we install, service, and stand behind, matched to what your in-home water test actually finds.

Softens hard water and knocks down chlorine taste and odor in a single tank — a good fit for RI homes on city water dealing with both at once.

Strains sediment, dirt, and rust out of your water before it reaches your plumbing — a simple, physical first line of defense with nothing to regenerate.

Our standard whole-home softener — hard-water minerals are gone at the source, backed by a self-cleaning valve that just keeps working.

Conditions hard-water minerals so they stop sticking to pipes and fixtures — no salt, no chemicals, no regeneration cycle, and no drain line.

A two-tank system built specifically for Rhode Island well water — sediment, iron, and sulfur odor, treated in stages for more consistent results.

Two tanks in sequence for homes that want the strongest treatment of municipal water available — chlorine, sediment, and hardness, all handled.

Oxidizes iron and rotten-egg sulfur odor out of well water, then filters the byproduct out completely — built for the toughest well water in Rhode Island.
Every system above is built from independently certified parts — not just the unit, but the media, the tank, and the valve inside it.
NSF and WQA Gold Seal are independent third-party certifications. Ask to see any of these certificates at your water test.
We test your water first, then match it to the system that actually fixes it — no guesswork, no upsell.
