Sewer line cost by method in Colorado
Enter the run length (most home laterals are 40–100 ft, house to street). Per-foot ranges are localized to Colorado labor.
| Method | Per foot | Total (60 ft) |
|---|---|---|
Open-trench (dig & replace) Traditional dig-up. Cheapest per foot but adds surface restoration (lawn, driveway, patio). | $55–$136 | $3,250–$8,200 |
Pipe bursting (trenchless) Pulls a new pipe through the old one via two access pits — minimal digging. | $65–$218 | $3,900–$13,100 |
CIPP lining (cure-in-place) A resin liner cured inside the existing pipe. No trench, but the pipe must be intact enough to line. | $87–$273 | $5,250–$16,350 |
Add surface restoration for open-trench (concrete/driveway $2–$25/sq ft) and permits where a run crosses into the public right-of-way. Per-foot ranges are national benchmarks localized to Colorado labor — a research estimate, not a quote.
