Septic pumping & service in Marysville, Ohio

Union County's five-year permit cycle and annual aerator inspections.

Marysville, the Union County seat, is mostly on city sewer, but much of Union County is rural, with farmhouses, newer homes on large lots, and small villages relying on septic systems. Union County's soils, like Delaware County's, are largely slow-draining glacial till, so aerators, mounds and other engineered systems are common on newer lots.

Operation permits run on a five-year cycle at $50 ($10 per year). The current permits cover 2025–2029, and renewal notices are mailed the fall before expiration. Unpaid fees can be added to property taxes.
Many systems, especially aerators and discharging systems, need an annual inspection. You can meet that with a contract with a registered service provider, by registering to service your own system, or by having the health department inspect (inspection only, no maintenance).
New systems need a site and design application, house plans, and a soil report from a registered soil scientist, and get a follow-up inspection 12 months after installation.
UCHD publishes lists of registered service providers and septage haulers.
