Septic System Installation questions

Do I need a permit?

Yes. Every county here requires a construction permit and, in most cases, a soil or perc evaluation first. See our permit requirements pages by county.

How long does installation take?

Typical residential installs run 1 to 3 days of on-site work once permits are approved; the permit and evaluation stage usually takes longer than the digging.
