Separate the Causes
Check whether the issue starts with excess water, solids, damaged piping, pump delivery or soil saturation.
Review Distribution
A blocked box, damaged lateral or dosing problem may affect only part of a system. Confirm the actual condition.
Check the Permit Scope
DEQ classifies repair work. Replacement of an absorption facility or treatment unit can require major repair review.
Protect the Soil
Keep roof runoff, traffic, paving and excavation away from the treatment and replacement areas.
Choose Repair or Replacement
Explain practical options and limits. Aeration or additives are not a guaranteed cure for failed soil treatment.
