What does septic system installation cost?
A conventional septic system typically costs $3,600 to $12,500 installed. Alternative systems (aerobic, mound) for difficult sites run $10,000 to $20,000. Soil conditions drive most of the difference, which is why a soil or percolation test comes first.
Do I need a permit to install or replace a septic system?
Almost always. Your state or county health authority must permit new systems and most repairs, and the design has to match a soil evaluation of your site. Licensed installers usually handle permitting as part of the job; confirm it is included in the quote.
Before you hire
Confirm the license number on this page is still active with Idaho, ask for proof of insurance, and get at least three written quotes; pricing on this work varies widely by site conditions.
