Family Owned and Operated Since 1975, Serving Knox & Licking Counties



On-Site Sanitation, LLC, started in 1975 by Ed and Sue Sims, serves the Mount Vernon, Ohio community with quality sanitation, service, and septic tank maintenance. They founded the company on the value of doing something worthwhile for someone else being their most important service—a value that they built a long lasting company on.

Together, they strive to maintain the same high level of excellence that his parents started. Together, with the rest of his highly trained team, they work hard to bring you the best and most efficient septic tank repair service.
