Septic Tank Pumping Companies in Washington

According to the Washington State Department of Health, state and local public health regulations require septic system owners to have a complete evaluation of their system every one to three years. Your local health jurisdiction can confirm the schedule for your system type.

The Department of Health says to have the tank pumped if scum exceeds 6 inches, sludge exceeds 12 inches, or total depth exceeds 18 inches. Island County also offers a rule of thumb of every 3 to 5 years. An inspector or pumper can measure these layers for you.

It depends on the county. Spokane Regional Health District, for example, requires owners of onsite sewage systems, including holding tanks, to obtain an operational permit and submit inspection records annually or every three years. Conventional gravity systems are inspected every three years, other system types annually, and holding tanks annually.

The Department of Health directs homeowners to their local health jurisdiction or local health department for guidance and for licensed professionals. They can explain the inspection and pumping requirements that apply to your address.

The Department of Health recommends avoiding garbage disposals and septic additives, fixing leaky toilets promptly, spreading out water use, keeping heavy equipment and vehicles off the drain field, diverting gutter and sump pump water away from it, and avoiding deep-rooted plants nearby.
