The registration Health and Safety Code 117405 requires
Under Health and Safety Code 117405, nobody may clean septic tanks, chemical toilets, cesspools or seepage pits, or dispose of the cleanings, without an unrevoked registration from the local health officer of the city, county or city and county. Ask the company for it by name. Then call the issuing office and confirm it hasn't been revoked, since that's the word the statute turns on.
One pumping visit in California: the range seven company prices set
Our model's figure is $325 to $600 per visit, an estimate, not a quote. It's the middle half of seven California companies' published pumping prices, and our national estimate only sets a floor under it.
EPA's row is a national maintenance figure spread over three to five years, so it isn't the price of one visit.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $325 to $600 per visit | The middle half of 7 California company prices for this job (25th to 75th percentile, $325 to $600); our national estimate ($275 to $865: built from one national published range, adjusted by the California septic tank servicer wage ratio (1.08)) only sets a floor, and the companies' lower quarter sits above it. Seven California companies publish a septic pumping price or typical range (only two print a firm $450) and one a $350 inspection; the pumping range is the middle half of those pumping prices, and a single inspection price is too few to move that estimate. Installation prices from three companies (from $5,000 in the Central Valley to $20,000 or more in the Sierra foothills) are recorded in the price file and not used. Basis: company sample (n=7), interquartile range. |
| Septic tank servicer pay, California mean | $27.70 an hour | What the people who pump tanks in California are paid (BLS, May 2025, statewide), which is not the price you're charged. |
| Routine maintenance every three to five years (U.S. EPA, national) | $250 to $500 | EPA's national maintenance figure; not a California price for one visit. |
Estimated range. Built from national published ranges (1 source), adjusted by California's septic tank servicer wage ratio to the US (1.08, BLS May 2025). Not a quote. Seven California companies publish a septic pumping price or typical range (only two print a firm $450) and one a $350 inspection; the pumping range is the middle half of those pumping prices, and a single inspection price is too few to move that estimate. Installation prices from three companies (from $5,000 in the Central Valley to $20,000 or more in the Sierra foothills) are recorded in the price file and not used. Seven California companies publish a price we could count for this job, so the range runs from the lower quarter to the upper quarter of those prices (the middle half of them). Full method. Prices as of Oct 23, 2026.
Pumping interval: ask the county program
None of the state sources on this page sets a pumping interval, so ask your county's environmental health office whether its program does. EPA's national cost comparison counts routine maintenance every three to five years. Keep the date of every visit.
Pumping calls that can't wait for a booking
- Wastewater is coming up through a floor drain, tub or toilet.
- Sewage is surfacing in the yard or pooling over the tank.
- A routine pumping that your county or company has put on the calendar.
- One slow sink while the rest of the house drains normally.
Before the truck is booked
- Find the tank lid if you can, and the date of the last pumping.
- Ask for the company's registration from the local health officer, and call that office to confirm it.
- Get the price in writing, with what it covers.
What a pumping visit needs on paper
The paper to see is the pumper's registration from the local health officer. If the visit turns up a failing system, it falls into Tier 4, and the local agency's program says what the repair needs.
