Notes
- Where the number comes from. The national price for a septic drain field replacement is $13.00 per ft² of drain field — drain field replacement pricing published for 2026, $8–$25 per ft² of field. Labor is about 55% of that. Septic Tank Servicers and Sewer Pipe Cleaners near Federal Way, WA average $68,670 a year against a U.S. mean of $53,500 — a factor of 1.284 — so the labor half is scaled by that and the material half is not. Source: BLS OEWS May 2025 for the Seattle-Tacoma-Bellevue, WA metro area, SOC 47-4071.
- Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
- What is in the price: excavation, gravel or chamber media, perforated pipe, the distribution box, backfill, grading and labor.
- What is not: the tank itself, a new perc test, engineered plans, a pump chamber if the site needs one, and county permits. These are the lines that turn a $15,027 quote into a $18,784 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.
