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 Cranston, RI average $51,290 a year against a U.S. mean of $53,500 — a factor of 0.959 — so the labor half is scaled by that and the material half is not.

- 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 $7,623 quote into a $9,528 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.

What the quote should include
The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $7,623 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. 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 national average.
If a bid lands outside $4,691 – $14,659, that is not automatically wrong — but it is the question worth asking out loud.
