Applicant site preparation, test-pit excavation, septic permit, system design, and construction.

  1. Choose new-site, repair, or recertification scope before comparing the fee.
  2. Follow the agency's test-pit and site-preparation requirements.
  3. Remember that a completed evaluation does not itself guarantee septic approval.
