    The cheapest septic system you will ever own is the one you have now. Protect your investment. Regular inspections help find and correct problems before they become major. Save money and avoid costly repairs or system replacements.

    A septic system that needs repairs can impact water quality of streams, lakes, and Puget Sound. If your system has any of the issues below, contact your septic service provider to fix them immediately:

    • Surfacing sewage.
    • Broken or missing baffles.
    • Septic tank needs pumping.
    • Tank level too high.
    • Tank not watertight.
    • Pumps not working correctly.
    • Lids not secure.
    • Soil layers that have become impermeable.
    • A saturated drainfield.
    • Broken or disconnected pipes.

    An inspection is not the same as a pumping. Inspections include measuring water levels in the tanks, checking any pumps, and evaluating the drainfield.

    The Health Department’s Environmental Health Code, Chapter 2, Section 44, lists the parts of your system a certified septic professional inspects:

    • Septic tanks. Inspector checks:
      • Liquid level.
      • Amount of scum and sludge.
      • Whether the tank needs pumping.
      • The condition of the tank and its parts and structural integrity.
    • Pump tanks. Inspector checks:
      • Liquid level in the tank.
      • The amount of sludge.
      • The pump tanks structural integrity and condition.
      • All pump controls and electronics, note the drawdown, dosing, cycles and squirt test if possible.
    • The drain field area. Inspector:
      • Walks the drainfield area and looks for surfacing sewage and damage to the drainfield area.
      • Checks monitoring ports–if available–for ponded sewage.
    • Risers or access ports:
      • Inspector checks lids and caps to ensure they are secure and in good condition.
    • Sand filters:
      • Inspector checks if filter operates properly and is in sound condition.
    • Proprietary devices like pretreatment devices:
      • Inspector checks if device operates according to manufacturer’s specifications.

     The inspector files a report in the onlineRME database. We review reports and send you a letter if your system requires repairs. You can view inspection reports at under “Report Search.”

    • The property configuration.
