Serving the Texas Hill Country & San Antonio since 1989
Seguin water is not Hill Country water. The city blends Guadalupe River water with Carrizo-Wilcox groundwater, and that mix calls for a different approach than towns further west.
The City of Seguin holds water rights on the Guadalupe River and also receives groundwater from the Carrizo-Wilcox aquifer through the Schertz-Seguin Local Government Corporation. What reaches your tap depends on how those sources are blended.
River water needs disinfection, which brings the chlorine taste many people notice. Carrizo-Wilcox groundwater is sand rather than limestone, and it is more likely to carry iron and manganese than the very high hardness of the Hill Country.
Outside city limits, rural homes across Guadalupe County depend on private wells. Depending on the formation, that water can be hard, iron-rich, or both, and it reaches the house untreated.
Everything we do is available across Seguin, McQueeney, Kingsbury, Geronimo and the rest of Guadalupe County.
Ion-exchange softening sized to your hardness reading, for city and well supplies.
Iron, sulfur, sediment, bacteria and pH, the pre-treatment a well needs.
Carbon and sediment stages for chlorine, taste, odor and grit at every tap.
A lot of the water treatment advice online for this region assumes very hard limestone water. Seguin’s supply is a different mix, so the right system here may lean more on carbon filtration for taste, or on iron removal, than on a large softener.
That is exactly why we test first. You get your actual hardness, iron and pH numbers, and a system sized to them. If a smaller system or a simple carbon filter is all your water needs, we tell you.
We have been testing and treating water in this part of Texas since 1989, and we answer the phone ourselves.
Family-owned, locally operated, and still on the same phone number after thirty-six years.
Class 3 certified by the Texas Water Commission and licensed by the Water Quality Association.
We supply the equipment and install it ourselves, with one written price that covers the whole system.
Softening, filtration and drinking water designed as one system for every tap, shower and appliance.
We test at your property, explain the numbers and put the recommendation in writing, at no charge.
Capacity and stages chosen from your test result, not from a regional average or a catalogue page.
If you are close to Seguin and not listed, call anyway. We probably cover you.
Comal County, city water and the Guadalupe River.
City supply, hard water and everything north of Loop 1604.
Hays County, city water and the San Marcos River.
It varies with the blend of river and groundwater, and private wells differ again. A free test gives you your exact number rather than a regional guess.
River water needs disinfection before it is safe to drink. Whole-house carbon filtration removes the taste and smell.
Orange usually means iron and black often means manganese, both common in Carrizo-Wilcox water. They need filtration ahead of any softener.
Maybe not. It depends on your hardness reading. Some Seguin homes are better served by carbon filtration or iron removal first.
Yes, along with the rest of Guadalupe County.
It depends on your water and your household size. After the free test you get a firm written price for the complete system, installed.
Seguin water is a blend. Guadalupe River water and Carrizo-Wilcox groundwater, rather than Hill Country limestone.
River water means disinfection. That is the chlorine taste, and carbon filtration removes it.
Carrizo groundwater leans toward iron and manganese. Those cause orange and black staining and need filtration before a softener.
Hardness still varies. Some homes need a softener and some do not, so we size from your reading.
Rural wells need their own test. Private wells across Guadalupe County draw from different formations and can differ a lot.
We have served Seguin and the San Antonio area since 1989. We supply the equipment and install it ourselves, as one job with one written price.
A whole house system treats every tap. Showers, laundry, the water heater and the kitchen all get the same treated water.
Testing is free and carries no obligation. Some visits end with us telling you a smaller system will do the job.
| Seguin supply | Common issue | What we usually fit |
|---|---|---|
| City water | Chlorine taste and smell | Whole-house carbon filtration |
| City water | Scale and spotting | Softener sized to your reading |
| Private well | Orange staining from iron | Iron filter ahead of the softener |
| Private well | Black staining from manganese | Manganese filtration |
| Private well | Bacteria present | UV disinfection |
| Any supply | Flat drinking water | Reverse osmosis at the kitchen tap |
Is Seguin water hard? It varies with the blend of river and groundwater. A free test gives you your exact number.
Why does Seguin city water taste like chlorine? River water needs disinfection. Carbon filtration removes the taste.
What causes orange or black stains? Usually iron or manganese, both common in Carrizo-Wilcox water.
Do you cover all of Guadalupe County? Yes, Seguin, McQueeney, Kingsbury, Geronimo and the surrounding area.
Seguin sits on the Guadalupe River east of the Balcones Escarpment, below the Hill Country. The geology under it is sand and clay rather than limestone.
The Carrizo-Wilcox is one of the most important aquifers in Texas, and it supplies Seguin, Schertz and other cities through regional pipelines.
Water from sandy aquifers like the Carrizo tends to carry iron and manganese. Those cause staining on fixtures, laundry and in toilet tanks.
Iron and manganese need to come out before a softener, or they foul the resin and shorten the life of the system.
Taste is often the first complaint we hear. Disinfected river water is safe, and carbon filtration makes it pleasant to drink as well.
Our advice for anyone in Seguin is simple. Do not assume your water is like Hill Country water, get it tested, and size the system from the numbers.
Check any of this against the primary sources:
