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.
