Hillsborough County
Local water
Tampa's municipal water comes from the Hillsborough River, and the City's 2024 water quality report puts average total hardness at 185 mg/L — 10.8 grains per gallon, which the USGS classifies as very hard. The pool-like taste people notice is chloramine, formed by adding chlorine and then ammonia so the water stays disinfected through the pipes. Hardness and chloramine are separate problems: softening handles the first, carbon filtration the second.

A free test confirms it, but these are the systems Tampa homes ask for most.
Yes. Tampa Bay Water serves much of the city, and the supply is consistently on the hard side — enough to leave spots on glassware and scale inside water heaters and fixtures. A free in-home test gives you the exact number for your address.
The City of Tampa's 2024 report describes adding chlorine to filtered water and then ammonia to create chloramine, so the water stays disinfected as it travels through the pipes. Chloramine is what most people are tasting. It does not dissipate the way free chlorine does if you leave a jug on the counter, so reducing it takes a properly sized carbon filter at the point of entry.
Most Tampa homes benefit from one because the city water is hard whether you're downtown or in the suburbs. The softener stops scale and spotting and helps your appliances last longer — the free test confirms whether it's worth it for you.
The City of Tampa's 2024 water quality report gives an average total hardness of 185 mg/L for its finished water, which the City states is equivalent to 10.8 grains per gallon. The USGS classifies anything above 180 mg/L as very hard. That is a system-wide average — we measure your actual hardness on-site for free, so any system is sized to your reading rather than an average.
Yes. We work throughout Tampa, including older homes where existing plumbing needs a careful, code-compliant install. We'll assess your setup during the free in-home visit.
