System Inspections

As you may know, the Health Department requires all septic systems to be professionally inspected at regular intervals. In Washington State septic systems with pumps are required to be inspected every year while gravity septic systems are required to be inspected every 3 years. Our office has worked with Clark County Public Health and helped their agency to obtain a waiver from the WA Department of Health to reduce the inspection frequency for Pressure Distribution type sytems from one year to two years. Now in Clark County all gravity systems, regardless of a pump or not, are required to be inspected every 3 years. Pressure Distribution systems are required to be inspected every 2 years and all other alternative type systems are required to be inspected yearly (Note- Some system manufacturers recommend inspections more often for the first two years (more advanced type systems); be sure to meet the conditions of your warranty).

Clark County has many licensed septic inspectors. If you want to see a whole list of Clark County approved septic inspectors, please visit :

Some specialize in different types of systems or work mostly in cetain geographic areas. Many pumpers will also inspect your system. If you need a referral, please give us a call at (360)687-9919. If your property is in Skamania County, Cowlitz County, Wahkiakum County or Pacific County, we know good people who can serve you there as well.

These required inspections have several objectives:

• Check the sludge and scum layers in the tank to determine if the tank needs to be pumped.
• Check the inlet and outlet baffles and filter
• Check for proper float and pump functions (if so equipped)
• Check pre-treatment device for proper function and treatment (if so equipped)
• Check all effluent distribution plumbing for signs of plugging – pressure jet if necessary.
• Check timer settings (if system so equipped)
• Check for signs of groundwater intrusion and hydraulic overload.

With the increasing complexity of septic systems today, it is important to choose a contractor who understands the technology required for your project. Many contractors are good excavators, but don’t necessarily have the expertise or specialized equipment needed to successfully install advanced treatment systems. For highly advanced treatment systems and those which are proprietary in nature (AdvanTex filters, Enviro-Flo Aerobic sytems, Glendon Biofilters, etc), the installer must also be trained and pre-qualified by the product manufacture.

EGSD recommends hiring contractors who are members of the Washington On-Site Sewage Association (WOSSA). WOSSA is a state-wide association dedicated to the education and professionalism of the septic industry.
