Three things people notice first

Most water problems in Dallas and Houston come down to one of these three. Each one is treated differently, which is why the assessment comes first.

Dallas runs on surface water

Dallas Water Utilities draws entirely on surface water, from seven reservoirs in the Trinity River system including Lakes Ray Roberts, Lewisville, Grapevine, Ray Hubbard and Tawakoni, treated at three plants.

Houston blends two sources

Houston's Main System blends surface water from the San Jacinto River at Lake Conroe and Lake Houston, and the Trinity River at Lake Livingston, with groundwater from 104 wells in the Evangeline and Chicot aquifers.

In Houston it changes by address

Houston is served by six separate water systems, and many suburbs including Cypress, Katy and The Woodlands sit on their own Municipal Utility District wells rather than City of Houston water, so what comes out of the tap changes address to address.

Chlorine, chloramine and PFAS

And the stuff you cannot taste.

Chlorine

You can usually taste it.

Chloramine

Most people cannot.

PFAS

Nobody can.

Which is why the assessment starts with what your utility publishes about Dallas and Houston water, not a guess.

Questions we get asked

If yours is not here, send it with your assessment request. There is no wrong question about your own water.

We call and go through your water with you. Then you get the system we would put in and the exact price. The assessment is free.

The number we put in writing is the number. If something in your house would change it, you hear about it before any work starts.

Wherever the water enters the house, usually a basement, a utility room or a garage.

Enough floor for the tanks plus room to open the cabinet lid and get to the bypass.

Top up the cabinet when it runs low. That is the whole routine, and the setup notes cover it.

Yes. A private supply changes through the year, so it gets sized differently from a municipal one. We handle both.
