History of the Washington Onsite Sewage Association
WOSSA was formed in 1990 to provide a united defense against a lawsuit that impacted non engineering designers in the State of Washington as affected third parties.
The legal right of local health jurisdictions to certify licensed engineering designers was challenged in court. WOSSA was able to make a reasonable defense and participate in the process, which has allowed non-engineers to continue to practice.
This effort helped lead to the current statewide designer licensing program currently being developed and administered by the Department of Licensing.
From that beginning, the organization has grown to encompass all disciplines within the industry, from regulators to pumpers. In about 1998, the state Pumpers organization merged with WOSSA adding their voice.
Bill Stuth Sr., was WOSSA’s first President, serving from 1990 to 1992. He is also one of the two original founders of WOSSA. Jerry Stonebridge was the other founding member of WOSSA and served as WOSSA President from 1995 to 1997.
