How Much Does a Water Well Treatment System Cost in Texas?
Quick Answer
Well water treatment systems cost $600–$6,000+ in Texas. An iron filter runs $800–$2,500; a full multi-stage system $3,000–$6,000 installed.
Well water treatment costs in North Texas depend almost entirely on what’s in the water. Iron contamination, hardness, and bacteria are the three most common issues — and each has a well-established treatment solution with a predictable cost range. Here’s what to expect.
Common North Texas Well Water Problems and Treatment Costs
Iron and Hardness (Most Common)
Hard water and iron are the default challenge across limestone-formation counties in North Texas (Wise, Cooke, Parker, Hood, Erath, Palo Pinto). Both cause visible damage to fixtures, appliances, and laundry over time.
| Treatment System | What It Solves | Installed Cost |
|---|---|---|
| Iron filter (oxidizing media) | Iron, manganese, rotten egg smell | $800–$2,500 |
| Air injection iron filter | Iron, manganese, H₂S odor | $1,200–$3,000 |
| Water softener | Hardness (scale, soap scum) | $800–$3,000 |
| Iron + softener combo | Iron, manganese, hardness | $2,000–$5,000 |
Bacteria Concerns
Bacteria — particularly coliform — is addressed through disinfection systems. UV is the most common choice for wells because it adds no chemicals and requires minimal maintenance.
| Treatment System | What It Solves | Installed Cost |
|---|---|---|
| UV disinfection unit | Bacteria, viruses | $500–$1,500 |
| Chlorination system (chemical feed) | Persistent bacteria, ongoing contamination | $800–$2,000 |
Drinking Water Quality
Even a well that passes a whole-house filter may benefit from point-of-use treatment at the kitchen sink for drinking and cooking water.
| Treatment System | What It Solves | Installed Cost |
|---|---|---|
| Under-sink RO (5-stage) | TDS, nitrates, minerals, taste/odor | $300–$800 |
| Whole-house RO | High TDS throughout the home | $3,000–$8,000 |
Typical Complete Treatment Systems by Scenario
Scenario 1 — Iron and hardness only (most North Texas wells): Iron filter + water softener = $2,000–$5,000 installed
Scenario 2 — Iron, hardness, and bacteria concerns: Iron filter + softener + UV = $2,500–$6,000 installed
Scenario 3 — Comprehensive treatment (high TDS or agricultural area): Iron filter + softener + UV + under-sink RO = $3,000–$7,000 installed
Start with a Water Test
Don’t guess at treatment — test first. A basic water test ($50–$200) tells you exactly what you’re dealing with before spending money on equipment. Over-treating for problems you don’t have is wasteful; under-treating for problems you do have is ineffective.
We can collect a water sample during any service call and recommend a treatment solution based on actual lab results for your well.
