Septic System Estimate Template

Perc test, design, tank and drainfield, priced against soil nobody has dug yet. Free PDF, no account.

Edit this template

A septic system is designed by the soil, and the soil is tested in a hole the width of a bucket. Everything downstream of that hole — tank size, trench length, whether a conventional bed will do or the county requires a mound with a pump — depends on numbers that come back from a test the health department watches. So a septic estimate is written in two halves: the part priced against a design that exists, and the part that changes if the soil comes back slower than the test hole suggested.

This is an estimate, not a bill. Prices may change.
What this assumes
Priced as a conventional gravity system on the perc rate expected for this soil series. A slower rate, or a limiting layer nearer the surface, changes the design and this estimate with it.
Description Qty Rate Tax Amount
Soil evaluation and perc test
Witnessed by the county sanitarian; two test pits
1$875.00$875.00
1,250 gallon concrete tank, supplied and set
Includes risers to grade and effluent filter
1$4,300.00$4,300.00
Drainfield — conventional gravity trench, per linear foot
Estimated 300 ft on the design's assumed perc rate
300$31.00$9,300.00
Old tank pumped and crushed in place
As the county permits; removal would be quoted separately
1$980.00$980.00
Subtotal$15,455.00
Total$15,455.00
Terms
Perc test invoiced when complete. System deposit on permit issue, balance at the county's final inspection.

What this estimate commits you to

How long it stands
Thirty days from the date the county design is stamped; a design that has expired or been revised takes this estimate with it, and the health department's fee schedule changes at the county's own pace.
What it does not cover
Restoration of the site: seeding, topsoil, final grading beyond rough, driveway repair where the truck ran, and the removal of any tree or stump standing in the drainfield footprint.
What would change the price
The soil and the water table. A perc rate slower than the test pits showed, a seasonal high water table that forces a mound or sand filter with its pump chamber, rock in the trench line, and a replacement drainfield that has to go somewhere the excavator cannot easily reach.
How the client accepts it
Sign the estimate with the stamped design attached; we apply for the county permit on that signature and the install is scheduled for the week after it is issued.

What to put on a septic system estimate

  • The perc or soil evaluation as its own line, done and paid for before anything else is priced
  • The design the estimate is built on, by designer and permit number, and the system type it calls for
  • Tank size and material, and whether the old tank is pumped and crushed, pumped and filled, or removed
  • Drainfield trench length or bed area, since that is what the soil rate actually decides
  • County health department permit and inspection fees, at cost and named
  • That the estimate assumes a conventional gravity system unless the design says otherwise

Questions

Why can a septic estimate change after the perc test?

Because the perc rate sets the system. A slow rate means more trench, a shallower limiting layer means a mound or a sand filter, and either can add a pump chamber and its electrical work — so an estimate written before the soil evaluation is priced against a system the county may not approve.

Does the old tank have to be removed?

It has to be dealt with, and the options are priced very differently. Most counties accept pumping and crushing in place or pumping and filling with sand; a few require removal and disposal. Name which one your estimate assumes, because it is a machine day and a disposal fee apart.

Who pays the health department fees?

The homeowner, in almost every county, and the estimate should pass them through at cost rather than mark them up. They are public figures — a client can look up the schedule — and a marked-up permit line is the fastest way to make a fair estimate look dishonest.

About the free estimate generator

Is this estimate generator really free?

Yes. There is no fee, no trial period and no watermark on the PDF. Nothing on this page requires a credit card.

What is the difference between an estimate and a quote?

An estimate is your best assessment of what the work will cost and can move if the job does. A quote is a fixed price you are offering to hold. If the figure you are about to send is one you intend to stand behind, use the quote generator instead.

Does an estimate commit me to the price?

Not in the way a quote does. An estimate is an informed projection, and the document prints that in as many words — "This is an estimate, not a bill. Prices may change." What it does commit you to is being straight about why a final figure differs, which is why the exclusions are worth writing down.

Do I need to create an account?

No. Fill in the form and download the PDF directly — there is no sign-up and no login for this tool.

Can the client accept the estimate online?

Not from a downloaded PDF — a file has no button. Saving the estimate to an account gives it a link the client opens and answers on, and the answer is recorded against the document.

What happens after the client says yes?

The estimate becomes an invoice for the same work. In an account that is one step and the figures carry across; from a PDF it means typing them again.

Can I use this for any currency or country?

Yes. Choose any currency and country for either party — the totals and formatting follow your selection.
