The RO city
Cape Coral was one of the first cities of its size in the U.S. to rely completely on reverse osmosis to make its drinking water. Its Southwest RO plant is described as the oldest continuously operating RO treatment facility in the world, and by 1985 the city had the largest low-pressure RO plant anywhere. ([City of Cape Coral water report](https://www.capecoral.gov/2022 Water Quality Report 6.22.2023.pdf))
RO removes most dissolved minerals, which is why Cape Coral city water is only moderately hard. On city water, a whole-house softener usually isn't the priority. Filtration for taste and RO at the sink for drinking water are.
Why so many Cape Coral homes have wells
Cape Coral was built as a huge pre-platted city, with lots sold long before city water reached them. Early on, many lot owners simply dug their own wells. ([Florida Water Resources Journal](https://fwrj.com/techarticles/0417 FWRJ_t2.pdf))
Today, utility lines have expanded, but plenty of homes still run on private wells. And well water here is a different animal: local water treatment companies regularly report sulfur, iron and hard water as the common problems.
If you're on a well, the first step is a free well test. Then we build a well system in the right order for what's actually in it.
