Septic questions, answered
For homeowners in Delaware and Union counties.
Is this a septic company or the health department?
Neither. This site is a referral service. We connect you with one independent septic contractor who is registered with your county health district. Contractors pay us for referrals, and it's free for you.
How often should my septic tank be pumped?
Traditionally every 3–5 years. DPHD cites Ohio State University data suggesting about every 5.9 years for a typical three-bedroom home with three occupants. Household size, garbage disposals and tank size change that, so have the layers measured at each service.
How much does septic pumping cost?
HomeGuide lists $300–$700 typically, and $500–$1,000 with additional cleaning. Larger tanks, digging for lids and extra compartments cost more.
What is an O&M permit?
Under Ohio's 2015 sewage rules, health districts issue operation permits and run operation and maintenance programs so systems are evaluated periodically. In Delaware County, conventional systems have 5-year permits and mechanical systems 1-year permits. In Union County, permits run on 5-year cycles ($10/year), with annual inspections for many systems.
Does the O&M permit cost money?
In Delaware County, DPHD currently charges nothing for the O&M permit, but there's a maintenance inspection fee if the district has to do the evaluation ($75 on the 2025 schedule). In Union County, the operation permit is $50 per five-year cycle.
Does the contractor have to be registered?
Yes. Ohio requires septage haulers, service providers and installers to register with each local health district where they work (OAC 3701-29-03), with insurance, bonding, testing and continuing education.
My aerator alarm is going off. What should I do?
Cut back water use, check that the breaker hasn't tripped, and call for service. Don't just keep silencing the alarm or unplug the aerator.
Do I need a permit to repair my septic system?
Pumping and routine service don't need an installation permit. Alterations and replacements do, and must be done by a registered installer. Ask your health district.
Should I use septic additives?
Most experts say a properly used system doesn't need them, and some products can push solids into the leach field. Regular pumping is what works.
Which areas do you cover?
Delaware County (Delaware, Sunbury, Galena, Ostrander, Ashley and the townships) and Union County (Marysville, Richwood, Plain City area and the townships).
