Central Texas has some of the hardest water in the state. If you have lived here long enough, you have seen the white crusty buildup on faucets, the spotty dishes, and the dry skin after showers. The question most homeowners ask is: do I need a water softener or a water filter? The answer depends on what problem you are trying to solve.
What a Water Softener Does
A water softener removes dissolved minerals — primarily calcium and magnesium — that make water "hard." It works through a process called ion exchange. Hard water flows through a tank filled with resin beads that are charged with sodium or potassium ions. The resin grabs the calcium and magnesium and releases sodium in their place. Periodically the system regenerates by flushing the resin with a salt solution to recharge the beads.
What it fixes: Scale buildup in pipes and water heaters, spots on dishes and glass, dry skin and hair, stiff laundry, reduced appliance lifespan. A water softener can extend the life of your water heater by 3–5 years by preventing sediment accumulation.
What it does not fix: Chlorine taste, bacteria, sediment particles, or chemical contaminants. A softener only addresses mineral hardness.
What a Water Filter Does
A whole-house water filter removes contaminants from your water supply before it reaches any fixture in the home. The specific contaminants removed depend on the type of filter. Carbon filters remove chlorine, taste, and odor. Sediment filters catch sand, rust, and particulates. More advanced systems like reverse osmosis remove heavy metals, fluoride, and dissolved solids.
What it fixes: Chlorine taste and smell, sediment and rust particles, some bacteria and parasites (depending on filter type), chemical contaminants. Filtered water tastes better and is gentler on skin.
What it does not fix: Hard water. A standard water filter will not prevent scale buildup or the mineral-related issues that come with hard water.
Central Texas Water: Why You Probably Need Both
Most municipal water supplies in our service area test at 15–25 grains per gallon of hardness — well above the 7 gpg threshold that the Water Quality Association considers "hard." On top of that, city water is treated with chlorine or chloramine, which affects taste. Well water users in areas like Giddings, Lexington, and Rockdale often deal with even higher hardness plus iron, sulfur, or sediment.
For most Central Texas homes, the ideal setup is a water softener to handle hardness paired with a carbon whole-house filter to improve taste and remove chlorine. This combination protects your pipes and appliances while giving you clean, great-tasting water at every faucet.
Cost Comparison
Water softener installed: $1,500–$3,500 depending on capacity and brand. A family of four typically needs a 32,000–48,000 grain system. Annual salt costs run $100–$200.
Whole-house water filter installed: $1,000–$3,000 depending on the filtration type. Carbon filters need media replacement every 3–5 years ($200–$400). Sediment pre-filters should be changed every 3–6 months ($20–$50 each).
Combined system: $2,500–$6,000 installed. Kimco offers free water testing to determine your specific water chemistry so we can recommend the right size and type of system. We provide a flat-rate quote before starting any work.
How to Decide
If your main complaints are scale buildup, spots, and appliance damage — start with a water softener. If your main complaints are taste, odor, or water clarity — start with a filter. If you are building new or remodeling and want to address everything at once, a combined system is the most cost-effective approach.
