Designers & Professional engineers

If you are looking to hire someone to design a septic system, the only people allowed to do this are licensed on-site wastewater designers and professional engineers. Snohomish County Health Department does not license designers, this is done by the state. You can find licensed designers and engineers by using the Washington State Department of Licensing Lookup online. You may want to click on Advanced Search with License Details to narrow your results to those with an active license in our county and surrounding areas. You could also do an internet search for septic system designers, and use the DOL lookup to verify that they have an active license. We recommend getting multiple quotes to find a fair price.
