National averages are close to useless here. Frost depth, soil type, haul distance to a receiving facility and county permit fees all move these numbers, and all four are regional.
This is one chapter of our complete guide to owning a septic system.
Routine service
A residential pump-out generally runs a few hundred dollars, driven mostly by tank size and how far the truck has to haul the load afterward. That haul distance is why prices differ across county lines for identical work.
Filter cleaning, riser installation and minor repairs are usually incremental on the same visit, which is a reason to book them together.
Repairs and replacement
Pumps, floats and alarms are the common failures on systems that have them, and the least expensive to fix.
Drainfield replacement is the number that matters: commonly $10,000–$30,000, driven by soil evaluation results, system type and site access. A mound system on poor soil sits at the top of that range.
A complete new system, including design, permitting and installation, generally exceeds drainfield replacement alone.
What actually moves the price
Disposal. When a treatment plant caps septage intake, every hauler in that service area drives farther and completes fewer stops per day. That cost reaches the invoice.
Season. Frozen ground raises excavation cost and narrows the window. Work planned in October costs less than the same work forced in February.
Access. A tank under a deck or forty yards from the nearest truck position is a different job than one beside the driveway.

Common questions
Why is my neighbour's quote different?
Most often haul distance and tank size. Two houses on the same road can sit in different receiving-facility service areas.
Is a maintenance contract worth it?
If it locks a service interval and includes the county filing, usually yes — the failure mode it prevents costs five figures.
