Family-Owned Septic Company Serving Grass Valley, CA
For more than six decades, RS Clark Septic has been part of the Grass Valley, CA, community. Founded by Ron Clark in 1962, our company was built on hard work, hands-on experience, and a commitment to helping local property owners when they need septic and sewer service.
Today, RS Clark Septic remains family-owned, family-operated, and locally owned. While the equipment and technology used in the industry have changed over the years, our approach has remained simple: provide dependable service, treat customers with respect, and be available when problems cannot wait.
With more than 64 years of industry experience, we bring generations of knowledge to every job, from routine septic pumping to unexpected sewer emergencies.
