Live oak, cedar elm, and pecan trees are everywhere in Round Rock — and their roots are relentless. Here's why they invade sewer lines and how to keep them out.
Round Rock's established neighborhoods — Forest Creek, Cat Hollow, Round Rock West — are beautifully treed. But those mature live oaks, cedar elms, and pecans are among the most aggressive root producers in Central Texas, and they love sewer lines.
Why roots invade sewer pipes
Tree roots naturally seek moisture and nutrients. Even a hairline crack or a leaky joint in an older clay or cast iron sewer line releases warm, nutrient-rich water — an irresistible beacon. Roots enter, thrive, and eventually choke or collapse the line.
The warning signs
Multiple slow drains at once, gurgling toilets, sewage odors, and recurring clogs all point to root intrusion in the main line.
How we stop them
A sewer camera inspection confirms the invasion. Hydro-jetting cuts roots and scours the pipe clean. For recurring problems, trenchless CIPP lining creates a seamless, root-proof inner pipe without digging up your yard.
Prevent it
If you have mature trees near your sewer line, schedule a camera inspection every 2–3 years and consider an annual enzyme treatment to keep roots at bay.
