A damaged sewer line used to mean digging up your yard, driveway, or landscaping. Trenchless repair changed that. It fixes the line from the inside with little or no digging. Here is how it works and what it costs in Arizona.
Quick Answer: Trenchless Sewer Repair Cost in Arizona
Trenchless sewer repair in Arizona costs about $80 to $250 per foot, or roughly $4,000 to $12,000 for a typical residential line in 2026. Pipe lining and pipe bursting cost more per foot than open digging in some cases, but they save the cost of tearing up and rebuilding your yard, driveway, or slab.
How Trenchless Repair Works
Pipe Lining (CIPP)
A resin-coated liner is pulled or inflated inside the old pipe and cured in place, forming a new pipe within the old one. It works when the existing pipe is cracked or scaled but still mostly intact.
Pipe Bursting
A new pipe is pulled through the old one while a bursting head breaks the old pipe outward. It works when the old pipe is collapsed and cannot be lined.
When Trenchless Is an Option
- The line is cracked, offset, or root-invaded but reachable
- You want to avoid digging up a driveway, slab, or mature landscaping
- The pipe is intact enough to line, or accessible enough to burst
- A camera inspection has confirmed the condition
It starts with a camera inspection to confirm the line can be repaired trenchless. Our camera inspection cost guide explains that step.
Trenchless vs Traditional Replacement
Traditional dig-and-replace can be cheaper per foot but adds the cost of restoring everything you dug through. When the line runs under a driveway, patio, or mature yard, trenchless often wins on total cost. Our sewer line replacement cost guide covers the open-dig option.

| Pipe lining (CIPP) | $80 to $250 per foot |
| Pipe bursting | $100 to $250 per foot |
