How long does a septic system last in Cheyenne County?
A well-maintained septic system in Cheyenne County typically lasts 25-30 years, though some components may need attention sooner. The concrete septic tank itself can last 40+ years, while the drainfield — the most critical and expensive component — usually lasts 15-25 years depending on soil conditions (Cheyenne County has predominantly well drained soils).
