Both counties have required septic work to be filed with the health department for decades, which means the answer to “what am I signing up for?” is not a guess. Across nearly 850,000 household-years of service history in Pierce and King County, the typical septic household sees about six professional visits per decade — roughly four inspections and two or three pump-outs — and has about one problem found in that time.
| Measure | Figure | What it covers |
|---|---|---|
| Professional visits, all types | 6.11 | Per household, per decade |
| …of which inspections | 3.70 | Required on a cycle; see below |
| …of which pump-outs | 2.41 | Driven by use rather than a fixed calendar |
| Problems found | 0.97 | An inspection filed as deficient, whatever the severity |
| Repairs formally recorded as complete | 0.65 | A floor: a fix only appears if someone filed it |
That last row needs reading carefully. A repair only shows up in the records if somebody came back and filed the completed work, so 0.65 is a floor rather than an estimate of how many problems get fixed. It is the number formally recorded as fixed, not the number fixed.
And a problem, in these records, means an inspection filed with a status of Deficient. Severity is not recorded anywhere, so that covers everything from a missing riser lid to a failed drain field. It is not the same thing as a broken system.
This is the rule the rest of the site refers back to. Washington sets the inspection every owner must have carried out, and it turns on one distinction only: whether the system is just a septic tank and a gravity drain field, or anything more than that.
| System | How often it must be inspected |
|---|---|
| Septic tank and gravity dispersal | Every 3 years |
| All other systems, including pressure distribution | Annually |
A local health officer may require inspection more often, never less, so these are floors rather than targets. The distinction that catches people out is pressure distribution: it is not a gravity system, so it is on the annual cycle, and any source that groups gravity and pressure together is wrong about it.
In Pierce County there is a second layer. The Health Department classifies each system by risk rather than by type, which sets how often the result must be reported to them, and it designates the Key Peninsula Marine Recovery Area as the county's only Area of Special Concern. It assigns your property's classification individually and notifies you in writing — so check your notification, or contact the Health Department, rather than assuming a county-wide rule settles your property. Source: WAC 246-272A-0270(1)(e).
Inspection is the one piece of septic work that is a legal obligation rather than a judgement call, and it is also the one most often behind. Of the inspections filed across the two counties over the past decade, 18.2% found a problem. The rate depends far more on why the inspector was there than on the age of the system — a complaint callout turns something up far more often than a routine visit does. Selling a home triggers one regardless of system type, in both counties, and that is the inspection nobody can skip.
Pumping is not on a legal calendar the way inspection is. How often a tank needs emptying depends on its size, how many people are in the house, and how much actually goes through it, which is why the honest answer to “how often?” is a range rather than a number. Across the region the middle gap between one pump-out and the next is 3.18 years, with plenty of households either side of that for perfectly good reasons. An inspection measures the sludge and scum in your tank and tells you where yours actually stands.
Across more than 144,000 septic properties in the two counties, 34.3% have had at least one problem recorded at some point. That is a larger share than most people expect, and it is worth setting against the severity point above: a great many of those are small findings put right quickly, not failed systems. What the records do show is that a problem found once makes a problem found again more likely, which is the argument for dealing with a finding rather than letting it sit.
What gets installed is decided by how much suitable soil sits under the drain field, by a designer and the health department, rather than by preference. Of the systems in the two counties whose type is on record, 15.5% are advanced rather than simple gravity — mounds, sand filters, pressure distribution and proprietary treatment units. That choice has a long tail: an advanced system is inspected annually rather than every three years, which is worth knowing before it goes in rather than after.
Septic is not spread evenly across Pierce and King County: the ten largest septic towns hold 52.5% of all the septic households in the two counties. That is why this site has a page for each of the 45 towns with enough records to say anything useful about.
The other thing worth knowing is how much of the region is quiet in any given year. Only 25.5% of septic households had a professional visit of any kind during 2025 — three quarters had no service recorded at all. If you are wondering whether you are behind, that is the number to weigh yourself against.
| Year | Visits | Inspections | Pump-outs | Households served | Companies working |
|---|---|---|---|---|---|
| 2021 | 40,778 | 25,875 | 14,880 | 31,767 | 149 |
| 2023 | 39,001 | 24,928 | 14,039 | 30,814 | 166 |
| 2025 | 46,970 | 26,233 | 20,708 | 36,736 | 188 |
Total service volume is up 15.2% since 2021, and almost all of that growth is pump-outs rather than inspections — inspections have barely moved while pump-outs are up by around a third. More companies are working the region too, up from 149 to 188.
About this analysis. Washington requires septic work to be carried out by certified professionals who file a report with the county health department, which makes those filings a near-complete record of professional septic service rather than a survey sample. There is no response bias and nothing is self-reported by homeowners.
This page draws on more than 518,000 service records covering about 144,200 septic properties in Pierce and King counties between 1997 and 2026, as recorded by the Tacoma-Pierce County Health Department and King County Public Health. Around 315,800 parcels were checked in total; the roughly 171,500 found to have no septic records matter as much as the ones that do, because recording the misses is what gives every share on this site a known denominator.
Definitions and limits. A problem is an inspection filed with a status of Deficient; severity is not recorded, so it spans a missing lid to a failed drain field, and it is never the same thing as a broken system. A repair is a problem subsequently recorded as corrected, so repair counts are a floor rather than an estimate. Per-decade figures are rates across observed household-years, not a prediction for any individual property.
Scope. Figures were queried on 29 August 2026 and the underlying record keeps growing, so counts drift and are rounded here. No figure on this site describes any single company's results, and individual property owners are not identified.
A high-level alert at a Burien home turned out to be a pump timer set well outside the system's as-built specification, flooding the pump tank. We corrected the timer, pumped both tanks, tested the pump, and found root intrusion around the risers.
King County Public Health inspected food businesses 71,580 times between January 2024 and September 2026, and closed 27 of them. For restaurant plumbing the real risk is not the citation - it is the backup that stops service, and the closure that follows.
