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 free 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.
We test your water first, then match it to the system that actually fixes it — no guesswork, no upsell.
