Septic pumping in Covington, by the records
Every septic pump-out in King County is filed with the health department, which means we can say what actually happens in Covington rather than repeat a rule of thumb.
The middle gap between one pump-out and the next in Covington is 2.57 years, shorter than the regional median of 3.18 years. That is a description of what households here do, not a recommendation for yours: the interval that suits your property depends on how many people use it, how much water and solid matter go through it, the size of the tank and the type of system.
| Measure | Figure | What it covers |
|---|
| Median gap between pump-outs in Covington | 2.57 years | From about 702 observed intervals |
|---|
| Properties with no pump-out on record | 21.4% | A filing gap as much as a service gap |
|---|
| Last recorded pump-out over five years ago | 21.8% | Of properties that have one on record |
|---|
| Properties on septic in Covington | 1,185 | Not on sewer |
|---|
21.4% of septic properties in Covington have no pump-out on record at all. That is not the same as never pumped: county filings only become dense from about 2013, and a company that does not report would never appear. What it does mean is that nobody can currently demonstrate when those tanks were last serviced. Of the properties that do have one on file, 21.8% have not had a pump-out in more than five years, which is past the outside edge of the three-to-five-year range the EPA describes.
One caution on comparing towns. Some of the variation between them is real and some of it is a difference in how consistently pump-outs get filed locally, and these records cannot separate the two. Treat the figures as a description of Covington's paperwork as well as its plumbing.
If you do not know where your own system stands, a septic inspection measures the sludge and scum in the tank and tells you whether it needs emptying yet. There is more on how the interval is set, and the figures for every town we cover, on our septic pumping page.
