Serving Napa County Since 1947
Maintaining your septic system is a vital part of your home’s maintenance. We recommend pumping your septic tank every 3 to 5 years for optimal functioning.


Our Story- 75 Years and Counting!
Napa Septic Tank Service has been handed down through the family through three generations, beginning with Bill H. Kroplin, Jr. in 1947. When Bill retired, he handed the business to his daughter Vicki and son-in-law John Rawlins in 1960. They retired and handed the business to their daughter Laura and son-in-law Jose Ceja in 2010.
It is with pride and gratitude that Jose and Laura carry forth the tradition started by Bill and John, to serve the Napa County with high-quality workmanship, honesty and fair prices!
As a local, family owned and operated company, we value the quality that we put into every project. Our experienced staff strives to offer fair, honest and trustworthy service for every customer.
