  Certified Septic System Professionals  
 
 

Environmental Health maintains a current list of septic system professionals that are certified to perform services in Thurston County. Although we strive to keep these lists current, we recommend you check with your contractor to make sure they are still certified.

To be certified, contractors must pass a test and have their equipment (i.e. pump trucks) inspected every three years (for specific requirements, see Article IV [PDF], Section 23).


PLEASE NOTE


Thurston County does not regulate the business practices of certified contractors.
Get several estimates, check references, and be clear what services are requested
before hiring a contractor.


The following contractors are certified to perform services in Thurston County.
