Williamson County
We soften and filter the water where it comes into the house, and put a reverse osmosis tap by the kitchen sink. The system is sized to your house, and you see one price before anything is ordered.
In Williamson County, it usually starts with one of these three. Each calls for a different fix, so we look at your water before we suggest anything.
The City of Round Rock's 2025 water quality report states that the average water hardness in Round Rock is 249 mg/L, which it calls very hard water. Cedar Park's 2025 report lists hardness as CaCO3 at 183 ppm.
Eight of the ten utilities across our service area list chloramine, a mix of chlorine and ammonia, as their disinfectant. Round Rock's 2025 report averages 2.15 ppm, Leander's 2.40 mg/l and Taylor's 2.87 ppm.
Leander and Cedar Park drink Lake Travis water, Taylor draws on Lake Granger, and Hutto's main supply is Carrizo-Wilcox groundwater. Round Rock and Brushy Creek blend Lake Georgetown with Edwards Aquifer wells, so two homes a few miles apart can start from very different water.
About Heritage Water Co • Close to home
Heritage Water Co works with households across Williamson County on the water that comes out of their taps. Some want the scale gone from the shower glass, some want a better glass of water from the kitchen, and some are on a well and want to know where to begin. We look at where your water comes from and what you are noticing, then suggest softening, carbon filtration, reverse osmosis, well treatment or a mix of them. You get a plain answer and a system sized to your house.

First we talk through what you are seeing at the taps. Then we tell you which system fits and what it costs. If you say yes, a licensed, insured plumber puts it in and we show you how it works.
Tell us whether you are on city water or a well, and what bothers you about it, from the kettle to the laundry. That tells us where to start.
We lay out which system suits your house and your budget, and why. Ask as many questions as you like.
Once you pick a system, a licensed, insured plumber installs it and checks that it runs properly, and we walk you through the few things it needs from you.

Homes on a well get their own sizing and their own price.

This is one example setup. Yours gets sized once the assessment is done.
Don't see yours? Add it to your assessment request and we will answer it on the call.
We give you a call and talk through your water together. By the end you know which system we would fit and what it costs. The assessment itself is free.
The written price is the one you pay. If something about your house would change it, we tell you before any work begins.
At the spot where your water line comes in. Around here that is usually the garage, a utility room or an outside wall.
Floor space for the tanks, and enough room above to lift the cabinet lid and reach the bypass.
Keep the cabinet topped up. The setup notes explain it, and that is really all there is.
It does, sized another way. A private well shifts over the year, so it is set up differently from city water. We do both.
The quieter part of the list
Often noticeable in a glass.
Harder to pick out.
No taste to go on.
So the assessment begins with the report your utility puts out on Williamson County water, rather than a hunch.
We ask for your name, phone and email. We cover the rest on a short call.
