So what happens during our inspection of your home’s Alternative Septic System?

  • We thoroughly assess your Alternative Onsite Septic System (AOSS), checking the following:
    • If your system has a pump, is it functioning as designed?
    • Are the floats which turn the pump on/off and trip the alarm if something goes wrong working correctly?
    • Is the drainfield intact? We look to see if sewage is surfacing from a break in a line or other drainfield component. We also look for trees growing on or near the drainfield, which could damage the system’s integrity.
  • During this time, we also clean any associated filters and/or rake peat when applicable.
  • And at the end of each business day, we file our report online with the Loudoun County Health Department.
  • Afterward, we will provide you with a copy of our report for your records.
    • For more information on reports, check out no. 5 of our FAQs.
