A failing sewer line usually announces itself gradually, through slow drains that get worse over months, then a backup that will not clear, before it becomes obvious the problem is the underground line itself and not a fixture. In Erie, the two most common root causes are the same expansive clay that affects slab plumbing across the whole Front Range, and, closer to Old Town, decades of tree root intrusion into older lines.
What actually damages a sewer line here
The expansive clay under most of Erie swells when wet and contracts when dry, and a rigid sewer line does not flex with it. Over years, that movement pulls joints apart at connection points and can shift entire sections of pipe out of the grade they need to drain properly, so water sits instead of flowing, which is often what turns a minor issue into a full backup.
Older sections of Old Town Erie, built up during and after the town's coal-mining decades, still have some clay or early cast-iron laterals that are decades old, and those lines have had far more time for both soil movement and root intrusion to do damage. A camera inspection is really the only honest way to tell the difference between a line that needs one targeted repair and one that has multiple failure points and is better replaced outright.
Colorado 811 locates are required before any digging on a job like this, without exception, and that step typically adds a few business days to the timeline before excavation or trenchless work can begin. It is worth factoring into scheduling expectations upfront rather than being a surprise once the camera inspection confirms the line needs physical repair.

- Camera inspection of the full line length to map every problem area, not just the one causing the current backup
- Trenchless pipe lining or pipe bursting when the line's condition allows it, which avoids digging up a yard or driveway
- Traditional excavation and replacement when the line has collapsed sections or a grade problem that lining cannot fix
- A written explanation of what the camera actually showed, not just a recommendation to replace
| Method | When it fits | Disruption |
|---|---|---|
| Trenchless lining | Line is intact but cracked or root-damaged along its length | Minimal digging, usually one or two access points |
| Pipe bursting | Line diameter needs to increase or lining is not viable | Moderate, follows the existing line path |
| Open trench replacement | Collapsed sections, bellied pipe, or grade has failed | Most disruptive, but sometimes the only option |
Signs the sewer line itself is the problem
- Multiple drains backing up at the same time, especially the lowest one in the house
- Sewage odor in the yard, particularly after rain or snowmelt
- A noticeably greener or soggier patch of lawn tracing the line's path
- Gurgling toilets when a washing machine drains

A backup that keeps returning is usually cleared first with drain cleaning or hydro jetting so the camera can get a clear look at what is actually damaging the line before deciding on a repair method.
