Reverse Osmosis Water Systems in South Carolina

Dubya Water installs reverse osmosis (RO) systems that deliver the purest drinking water possible directly from your kitchen tap. Reverse osmosis removes up to 99% of dissolved contaminants including lead, arsenic, fluoride, nitrates, chlorine, and total dissolved solids. Whether you want crystal-clear drinking water for your family or need purified water for a specific application, our RO systems provide reliable, on-demand water purification without the expense and waste of bottled water.

How Reverse Osmosis Works

A reverse osmosis system pushes water through a semi-permeable membrane with pores so small that only water molecules pass through. Contaminants, dissolved minerals, and impurities are flushed away as waste water. Modern RO systems include multiple filtration stages: a sediment pre-filter, a carbon pre-filter, the RO membrane, and a carbon post-filter for final polishing. The result is exceptionally pure water stored in a pressurized tank under your sink.

What RO Removes

Lead, mercury, and heavy metals
Arsenic, fluoride, and nitrates
Chlorine and chloramine
Total dissolved solids (TDS)
Bacteria and viruses (when combined with UV)
Pesticides and herbicides
Pharmaceutical residues

Point-of-Use vs. Whole-Home RO

Most residential RO systems are point-of-use, installed under the kitchen sink to provide purified drinking and cooking water. Whole-home RO systems are available for situations where every tap needs purified water, but they require larger equipment and produce more waste water. Your Dubya Water technician will recommend the right configuration based on your water quality and goals.

Frequently Asked Questions

Under-sink RO systems typically cost $400 to $1,200 installed in South Carolina, depending on the number of filtration stages and features. Whole-home RO systems range from $3,000 to $8,000. Dubya Water provides free water testing and upfront pricing. Call (803) 855-1055.

Sediment and carbon pre-filters should be replaced every 6-12 months. The RO membrane typically lasts 2-3 years. The carbon post-filter is replaced every 12 months. Filter replacement costs average $50-$100 per year for standard under-sink systems.

Traditional RO systems produce 3-4 gallons of waste water per gallon of purified water. Modern high-efficiency systems have improved to 1:1 or even better ratios. The waste water can be redirected to garden irrigation or other non-potable uses.

Yes. Reverse osmosis water is safe and highly purified. Some people add a remineralization stage to restore beneficial minerals like calcium and magnesium for improved taste. Your Dubya Water technician can install a remineralization filter if desired.
