The History of Stuth Company

Stuth Company opened its doors for business in Washington State in 1962 as Stuth Ditching. The primary operation was the installation and repair of residential septic. By 1964, owner, William Stuth (Bill Stuth, Sr.) was designing septic systems and providing pump out services for septic tanks. In September 1975, Stuth Ditching incorporated and the name was changed to Stuth Company, Inc.

In 1972, Stuth Co., Inc. purchased and relocated the company to commercial property in Renton WA and began manufacturing septic tanks and other concrete products. The company operated with two installing crews. In 1975, Bill Stuth Jr. attained his installers license and operated his own installing crew. His involvement with the company allowed further pursuit in research and development area within the industry. For example, Stuth Company spearheaded a project for King County and the State of Washington Department of Health to study the advantages of compartmenting septic tanks. This study became instrumental in the state changing from single compartment tanks to compartmented tanks.

In 1984, Stuth Co., Inc. relocated to more favorable site on the Maple Valley Highway. Bill Stuth Jr. had become proficient at installing, designing, repairing and pumping. Both Stuth’s shared an appreciation and strong interest in troubleshooting and analyzing failed systems as well as gaining an understanding of new technologies. In 1985, Bill Stuth Sr. started a research program to determine the reason for a very high rate of failures in commercial septic systems. Separately, there was a team formed to comment on and review the information. The study determined the two most probable reasons for failure were FOG (fat, oils and grease) and shock-loading.

In 1994, Stuth Co., Inc. sold its concrete manufacturing operation and pump out service. This allowed more time to be dedicated to the installation of complex commercial systems, residential systems, consulting opportunities, and troubleshooting of residential and commercial septic systems across the nation.

In 1999, William Stuth Jr. purchased Stuth Company. Bill Stuth Jr. is a state licensed designer and licensed installer throughout many counties in Washington. He and his skilled crew have also installed systems in Oregon, California and Idaho. Bill Jr. has served as the Operations and Construction manager of Stuth Co., Inc for over 20 years. The company’s primary focus is to provide high quality installations and premium service at a competitive price, which meet the needs of both the environment and the customer.
