OSS O&M Providers

This is a list of individuals that are licensed by Cowlitz County to perform O&M inspections on septic systems. Cowlitz County does not endorse, guaranty, or warranty the workmanship of any of these companies or individuals.

There are three different levels of license for O&M professionals. Level I providers are licensed to provide inspections for gravity systems including pump to gravity. Level II providers can provide inspections on all types of systems except for those that are considered ’proprietary’. Proprietary systems must be inspected by a professional specifically approved for that product by the manufacturer.

Visit our webpage for more information on O&M requirements.

Do Your Homework

 As with any professional you hire, do your homework. The County is not able to give suggestions or references. If you have any complaints concerning one of these companies please report them to the Environmental Health Unit (EHU) at 360-414-5599, email at omseptic@cowlitzwa.gov, or fill out a Request for Investigation form and submit it to Health & Human Services.
