How do you finance a septic pump truck?
Septic pump truck financing usually means an equipment finance agreement: we pay the seller, the truck is the collateral, and your company makes one fixed payment a month. Here’s what new and used vacuum trucks were listed for in November 2026, what those prices work out to monthly, and what to check before you buy a used one.

How does septic truck financing work?
You find the truck. We pay the seller. Your company makes a fixed monthly payment until it’s paid off, and the truck itself secures the deal, so a blanket lien on the whole business usually isn’t needed.
Most pump trucks go on an equipment finance agreement (EFA). The truck is yours from the start, and the funder keeps a security interest until the last payment. EFAs run 24 to 84 months. A septic truck is a titled vehicle with a tank body on it, and when the tank, pump and hose come with the truck on one invoice, they go on one agreement together.
A septic truck goes through our vocational and utility truck financing, listed on our commercial truck financing page, and our vac truck financing covers the vacuum side, including combination sewer and jetter trucks. On a clean file, approval can come in as little as 30 minutes, and money can go out in as little as 24 to 48 hours once you’ve signed.
The work repeats, which helps. The EPA says household septic tanks are typically pumped every three to five years.
How much does a septic pump truck cost?
Roughly $85,000 to $275,000 in the dealer listings we checked. The low end is an older chassis carrying a fresh 2,500-gallon tank, and the top is a new three-axle truck with a 5,000-gallon tank.
| Truck | Tank and pump | Miles | Listed price |
|---|---|---|---|
| 2027 Western Star 47X, new | 5,000-gallon steel tank, NVE 4310 blower | Not listed | $275,000 |
| 2027 International HV, new | 4,000-gallon steel tank, Masport Cobra pump | Not listed | $188,000 |
| 2027 Freightliner M2, new | 2,500-gallon steel tank, NVE B500 blower | Not listed | $165,000 |
| 2026 Hino L6, new, derated non-CDL | 2,500-gallon steel tank, NVE B500 blower | Not listed | $144,900 |
| 2020 Kenworth T680, used chassis | New 3,500-gallon steel tank, NVE 887 pump | 306,232 | $115,000 |
| 2020 Kenworth T270, used chassis | New 2,500-gallon steel tank, Masport Mamba pump | 198,936 | $88,000 |
| 2018 Freightliner M2, used chassis, non-CDL | New 2,500-gallon steel tank, 422 CFM pump | 195,487 | $85,000 |
Listed asking prices we found, checked November 7, 2026, not appraisals or offers. All seven come from one vacuum truck dealer based in Georgia, linked in Sources, so they’re examples, not a national average. Tax, title and delivery may be extra.
All three used trucks carry a new tank on an older chassis, which puts them well under a new truck. For a sense of what a municipal buyer pays, Summit County, Ohio, put a new 2026 Peterbilt 548 vacuum tank truck for its sewer department before its council in March 2026 at up to $273,965.
What tank size, pump and license does the truck need?
The smaller trucks in the listings above carry 2,500 gallons, and the bigger ones run 3,500 to 5,000. A bigger tank means fewer trips to unload, but a heavier truck, a higher price and usually a CDL.
The pump matters about as much as the tank. Listings name the vacuum pump or blower and often its airflow in CFM. The 2018 Freightliner above lists 422 CFM, and the Western Star lists 940. Ask the seller for the pump’s make, model and service history, not just the tank size.
On the license, federal rules put any single vehicle with a GVWR of 26,001 pounds or more in the Class B CDL group. That’s why some dealers sell derated, non-CDL trucks, like the Hino and the 2018 Freightliner in the table. A derated truck can carry less weight, so check what it’s rated for against the loads you plan to haul, and confirm the license rules with your state.
What’s the monthly payment on a septic truck?
On a 60-month term, the trucks above land between roughly $1,760 and $5,710 a month. Five of them, for an established business putting nothing down:
| Truck | Listed price | 48 months | 60 months | 84 months |
|---|---|---|---|---|
| New Western Star 47X, 5,000 gallons | $275,000 | About $6,843 | About $5,709 | About $4,424 |
| New International HV, 4,000 gallons | $188,000 | About $4,678 | About $3,903 | About $3,025 |
| New Hino L6, 2,500 gallons, non-CDL | $144,900 | About $3,606 | About $3,008 | About $2,331 |
| 2020 Kenworth T680, 3,500 gallons | $115,000 | About $2,862 | About $2,387 | About $1,850 |
| 2018 Freightliner M2, 2,500 gallons | $85,000 | About $2,115 | About $1,764 | Depends on the truck |
Estimates for an established business on an EFA, nothing down, before tax, title, delivery or soft costs. “Depends on the truck” means we’d look at the chassis, tank and records first. No model year sets it, though older equipment typically gets a shorter term, and not every truck qualifies for every term. Your real payment will depend on credit, the equipment and the term. These are examples, not quotes.
Stretching the International from 60 to 84 months, if the truck qualifies, drops the payment by about $878 a month and adds roughly $19,900 over the life of the agreement. I’d pick the term by how long the truck will stay on your route. Run your own numbers in the Quote Builder, which doesn’t pull credit.
Adding a second truck? Say an established company buys the new Hino and the used 2018 Freightliner together. That’s $229,900 on one agreement, or about $4,772 a month over 60 months. Delivery or an extended warranty can usually be added to the payment too. How much can go on? Usually around 20% of the equipment amount, depending on credit and collateral.
Should you finance or lease a vacuum truck?
Most pumpers finance. A septic truck usually stays in the fleet for years, and an EFA means it’s yours once the payments stop.
Leasing is the other route. Our lease terms are 24 to 60 months, with a $1, 10% or fair market value buyout at the end. The FMV version usually has the smallest payment, which can suit a company that expects to trade up to a bigger tank in a few years. A financed truck and a leased truck need two separate agreements.
The structure also changes the tax picture, including Section 179, so ask your CPA before you choose.
What should you check on a used septic truck?
The tank, the pump and the chassis, in that order. This is buyer advice, not a Five West rule.
- Tank. Steel tanks can rust from the inside. Look inside if you can, and check the seams, the rear door seal and the valves for rust or leaks. A new tank on an older chassis, like several of the trucks above, takes care of most of this.
- Pump or blower. Ask for the make, the hours if it has a meter, and any rebuild or oil service records. Have it pull a vacuum while you watch.
- Hoses, shutoffs and hoist. Cracked hose and a sticky primary shutoff are cheap fixes, but they tell you how the truck was kept. If the tank hoists, run it up and down.
- DOT inspection. Federal rules say a commercial motor vehicle has to pass a periodic inspection at least once every 12 months, with proof kept on the vehicle. Ask for the latest report or sticker.
- Chassis. Miles, engine and transmission records, tires and brakes, the same as any work truck. Our used box truck checklist covers the straight-truck side well.
There is no age limit, though older equipment can be tougher to get done. Condition and records count, so send what you have.
Can you buy a used pump truck from another septic company?
Yes. Private-party purchases are welcome, and a titled truck is fine. We search for liens first, and a larger truck may get an inspection or appraisal. Payment goes directly to the seller. Does the seller still have a loan on it? Then we pay that lender off at closing, the lien comes off, and the seller gets the balance.
Because the lien search and inspection are built into the file, a private sale doesn’t slow things down compared with buying from a dealer. With good credit, you usually don’t need a down payment, even on a private sale. Before you hand anyone money, here’s how to check a truck for liens, and have your attorney look over the bill of sale.
Can you finance a grease trap pumping truck?
Yes. A grease truck is a vacuum truck too, so it goes through the same vocational truck financing. Some septic companies also pump grease traps for commercial kitchens, and the truck you buy for it is financed the same way as your septic rig. If you’re weighing a truck that also jets lines, combination sewer and jetter trucks are on our vac truck list, and our hydrovac truck financing guide covers the digging side of vacuum work.
Buying a jetter or a slide-in tank with the truck? Send the whole invoice and ask what fits on one agreement. The $15,000 usual minimum counts on the whole bundle.
What credit and time in business do you need?
For an established company, a 600 FICO is the starting point on many programs. Two or more years in business gets you the widest choice, and one to two years still works on many deals. With good credit, you usually don’t need a down payment.
A pumping company adding a second or third truck for routes it already runs makes a strong file. Steady deposits help too. The full list is on our qualification guidelines.
Can a new septic pumping business get a truck financed?
Sometimes, and experience in the work counts for a lot. A company under a year old goes through startup underwriting, which typically means 700+ personal credit, real time spent pumping tanks or running a route for someone else, and working capital left after the purchase. Startups usually put some money down.
Signed service contracts help if you have them. More in our startup equipment financing guide.
Frequently asked questions
Can you finance a used septic truck?
Yes. Five West finances used septic and vacuum trucks from dealers, auctions and other pumping companies. There is no age limit, though older equipment can be tougher to get done. Older trucks typically get a shorter term.
How much does a septic pump truck cost?
In the dealer listings we checked on November 7, 2026, trucks ran from about $85,000 for a used chassis with a new 2,500-gallon tank to $275,000 for a new three-axle truck with a 5,000-gallon tank. Those are listed asking prices, not appraisals or offers.
What is the monthly payment on a septic truck?
As an estimate for an established business with nothing down, a new 2,500-gallon truck listed at $144,900 comes to about $3,008 a month over 60 months, and a new 4,000-gallon truck at $188,000 comes to about $3,903. Your payment depends on credit, the equipment and the term.
Do you need a down payment for a septic truck?
With good credit, you usually don’t need a down payment, even on a used truck or a private-party sale. Startups usually put some money down.
Do you need a CDL to drive a septic truck?
Under federal rules, a single vehicle with a GVWR of 26,001 pounds or more falls in the Class B CDL group, which covers most full-size pump trucks. Some dealers sell derated non-CDL trucks with a lower weight rating. Check the rules with your state licensing agency.
Can I get working capital from a pump truck I own?
If your company owns the truck free and clear, it can back an equipment leaseback, since construction and vocational equipment both qualify. You pledge the truck, get a lump sum and keep running it, and the lien is released when the balance is paid. It takes two or more years in business, and funds typically arrive 2 to 5 business days after signing.
Picked out a pump truck?
Send the listing, the VIN and the mileage with one short application. A soft credit inquiry starts it, and a dedicated funding professional handles it from there to funding.
