Reverse Osmosis Water Filtration in St. George UT
St. George’s tap water is known for its hardness, and for containing minerals and contaminants that can affect taste, plumbing, and long-term health. A reverse osmosis (RO) water filtration system offers the highest level of protection, removing impurities that basic filters can’t touch.
At Element Plumbing, Heating & Air, we install, repair, and maintain reverse osmosis and whole-home filtration systems tailored to southern Utah’s unique water challenges.

How Reverse Osmosis Filtration Works
Think of reverse osmosis (RO) as a powerful, multi-step cleaning process for your water. It uses pressure and ultra-fine filters to remove even the tiniest impurities, things most other systems can’t catch.
1. Pre-Filtration
Before the water reaches the RO membrane, it passes through sediment and carbon filters that remove sand, rust, chlorine, and chemical odors. This protects the membrane and improves taste right from the start.
2. RO Membrane
Next, water is pushed through a microscopic membrane that removes up to 99% of dissolved solids, including arsenic, lead, PFAS, chromium, and nitrates. What gets through is clean, purified water; what doesn’t is safely flushed away.
3. Post-Filtration & Storage
Finally, the filtered water moves through one last polishing filter and into a small storage tank, ready whenever you turn on the tap. The result is crystal-clear, great-tasting water for drinking, cooking, and even making better coffee or ice.
In a city like St. George, where minerals and contaminants can build up quickly, reverse osmosis provides the purest, most reliable water possible, right from your own kitchen.

Why Reverse Osmosis Matters in St. George
Even though St. George’s city water meets federal safety standards, recent analysis from the Environmental Working Group (EWG) shows 15 contaminants exceeding EWG’s own health-based guidelines, including arsenic, trihalomethanes (TTHMs), and haloacetic acids (HAA5/9).
- Arsenic: 9.6 ppb — near the federal limit (10 ppb) and 2,400× higher than EWG’s ideal guideline
- Total TTHMs: 35 ppb — 236× higher than EWG’s benchmark
Radium 226/228: 0.89 pCi/L — 18× higher than recommended

Meanwhile, the city’s hard water levels (20–25 grains per gallon) accelerate mineral buildup and scale inside appliances and plumbing. As drought reduces supply and increases mineral concentration, filtration and purification systems are more essential than ever.
A reverse osmosis system provides a final layer of defense, delivering pure, great-tasting water right from your tap.
