The truck is most of what a septic pumping business costs to start. On November 8, 2026, one Florida dealer listed used septic trucks with 2,000 to 2,500-gallon tanks at $75,000 to $94,000 and new ones at $136,000 to $175,000; sellers on Pumper's classifieds asked $22,500 to $70,000 for trucks built from 1996 to 2013, most with 3,300 to 5,000-gallon tanks.^{8, 9} The truck's weight decides the license you need to drive it: at 26,001 lb or more, counting the rating or the scale weight, whichever is greater, you need a Class B CDL, plus the tank vehicle endorsement for a tank of 1,000 gallons or more.¹ After that come insurance for the truck, the job and a spill, a disposal fee of about 2 to 9 cents a gallon, and diesel at $6.29 a gallon.^{14, 15}

The trade press puts the problem plainly. "This is a capital-intensive business. Few people have the cash to buy a $200,000 septic truck," the co-owner of a new Texas septic company told Pumper in February 2026.⁶ On r/septictanks, a pumper whose company started with a $10,000 used truck added a warning about the truck itself: "You need to make sure the truck's GVWR is 26,000 or less if you don't have a CDL."¹⁰ Below: what trucks cost, how the weight line works with a full tank, the insurance, disposal and fuel, the break-even, and the state licenses on top. Pricing the pump-out itself is in how to price septic pumping.

The cost sheet does the arithmetic: make your own copy in Google Sheets or download the Excel version (.xlsx). Pick one, enter your email and I'll send the link. Put in your truck, your insurance quotes and your disposal plant's rate, and it works out what one pump-out costs, how many a month you need to cover the bills and your own pay, and how many gallons your truck can carry before it crosses the CDL line. It also holds the truck listings and disposal rates below.

Start with pumping, inspections and maintenance

Owners who did it say start small and add the big jobs later. "I focused on pumping, inspections and maintenance in the beginning and now offer new installations and repairs," one owner wrote in a June 2026 thread from someone thinking of starting.¹⁰ Another, in the same thread: "You don't need the best and shiniest equipment starting out. See if you can get something used but in good shape for a good price." He added a pricing rule worth taping to the dash: "if local companies are charging $400 to pump out, don't charge $200 just to get the business."¹⁰

Installs are where the equipment bill grows. A North Carolina installer listed what's waiting for a new septic business: "vehicles, trailers, and insurances," builders who "will want you to carry a million dollar insurance policy," workers comp, and supplier credit lines, with rainy weeks of no work in between.¹¹ A pump truck, a camera and a locator get you paid work while you build up to that.

A lot of new pumpers already run a plumbing shop. A Michigan plumber bought a used 2014 Freightliner with a 3,000-gallon tank because his plumbing customers kept asking; he and his wife took the state's required 10 hours of courses, started pumping in March 2025, and pumped "about 260,000 gallons in our first full year."⁷ If you're adding pumping to a Maryland plumbing shop, the state's septic rules are in Maryland septic license and registration.

What a septic truck costs, new and used

I read two sets of listings on November 8, 2026: Pumper's septic truck classifieds, where owners and dealers post, and the septic truck stock of one Florida dealer, National Truck Center.^{8, 9} These are asking prices, not sale prices.

Tank size is the first decision, and weight settles most of it. A bigger tank means fewer trips to the plant, but a 2,000-gallon load of water alone weighs 16,680 lb (8.34 lb a gallon), and that's before the chassis, the tank, the pump and the hose.⁵ The Texas company in Pumper chose a 2025 Mack MD6 with a 2,000-gallon tank and a jetter for its first truck, "like a Swiss Army knife."⁶ The Michigan plumber's used truck carries 3,000 gallons, and his wife is "looking into getting my Class B license so I can drive this truck."⁷ Which brings us to the line.

The 26,000 lb line: when a septic truck needs a CDL

The federal CDL rule has three parts that matter to a pumper, all in 49 CFR Part 383, and they apply "in interstate, foreign, or intrastate commerce," so a truck that never leaves your county is covered.²

• The weight. A single truck is a Group B commercial motor vehicle if it has "a gross vehicle weight rating or gross vehicle weight of 11,794 or more kilograms (26,001 pounds or more), whichever is greater." Driving one takes a Class B CDL.^{1, 2}
• The tank. A tank vehicle is "any commercial motor vehicle that is designed to transport any liquid or gaseous materials within a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more." A septic truck over the weight line with a 1,000-gallon tank or bigger needs the tank vehicle endorsement on the CDL. The endorsement is a knowledge test, and it's one of three that can go on a learner's permit.^{1, 2}
• The exception, and the trailer. Under 26,001 lb, a truck that carries no placarded hazardous materials and isn't built for 16 or more passengers isn't a commercial motor vehicle for these rules, so neither the CDL nor the endorsement applies, whatever the tank size. Hitch a trailer rated over 10,000 lb, though, and a combined weight of 26,001 lb or more makes it a Group A vehicle, which takes a Class A CDL.¹ Ask your state's CDL office before you tow equipment or haul anything other than household septage.

"Whichever is greater" is the part people miss. The door sticker sets the GVWR, but the scale sets the gross vehicle weight, and the rule counts the higher one. The pumper with the $10,000 truck again: "For us, that's our truck with a full 2000 gallon tank, and I think our truck might have been de-rated at the factory because it's stock GVWR is like 32,000."¹⁰ A de-rated sticker keeps you out of the CDL only while the truck really weighs 26,000 lb or less. Weigh it empty on a certified scale with you, the fuel and the hoses aboard, subtract that from 26,000, and divide by 8.34: that's the most you can load. A truck that weighs 14,000 lb empty can carry about 1,438 gallons, whatever its tank holds. The cost sheet's CDL tab runs those numbers for your truck.

Two more things. FMCSA's own CDL page says to contact "your State licensing bureau (e.g., Department of Motor Vehicles) for details," because states issue the license and test for the endorsement.³ And skipping the CDL doesn't skip every DOT rule: a truck of 10,001 lb or more that crosses state lines is a commercial motor vehicle for FMCSA's safety rules.⁴ For a truck that stays in your state, ask your state DOT which of those rules it applies.

Insurance: the truck, the job and a spill

A Central Texas designer and installer who knows "lots of pumpers and Maintenance Providers" said their "Major Complaints are with Insurance Companies charging them lots of money for the insurance premiums and Vehicle Maintenance costs. If the truck breaks down you aren't making any money."¹⁰ A pumping business needs three policies:

• Commercial auto on the truck. The standard personal auto form excludes vehicles used in a business, apart from a car, pickup or van you own, so a pump truck needs a commercial policy (more in contractor insurance).¹² Pumper describes the two halves: liability "covers injuries, damages and lawsuits if an employee is at fault in an accident," and physical damage "covers the cost to repair a vehicle." Independent agents write "nearly 90% of commercial auto policies," so start there.¹³
• General liability for damage at the customer's house, like a driveway cracked under a loaded truck. Minnesota won't issue an SSTS license without at least $100,000 of it.¹⁸
• Pollution liability. The standard general liability form excludes injury or damage "arising out of the actual, alleged or threatened discharge, dispersal, seepage, migration, release or escape of 'pollutants'," and it defines pollutants to include "waste."¹² A hose that splits on a front lawn is exactly that. Ask your agent, in writing, what covers a spill at a customer's house and on the road.

I found no owner who posted what a pumping business pays for these. The broker and vendor guides that give premiums don't say where their numbers come from, so the cost sheet carries placeholders marked "made up." Get three quotes before you buy the truck, because the insurer's answer can change which truck you buy.

Disposal fees and fuel

Every gallon you pump goes somewhere that charges for it. Five treatment plants' published rates for haulers, read November 8, 2026:¹⁴

So a 1,250-gallon pump-out costs $26 to $113 to dump, depending on where you are, and some plants charge by the truck's tank size, not what's in it. Call the plants near you before you price anything, and ask about permits, hours and whether they take septage from outside the county.

Fuel is the other per-job cost, and it moved a lot this year: US on-highway diesel averaged $6.292 a gallon in EIA's November 2, 2026 survey, $2.54 more than a year earlier.¹⁵ A 40-mile round trip (yard, house, plant, yard) at 7 miles a gallon burns about $36 of it. Your truck's mileage is your own number; fill the tank twice and divide.

Cost per pump-out and the break-even

The cost sheet splits the money in two. Fixed costs are what you pay whether the truck rolls or not: the truck payment, insurance, licenses, the phone and the office, and your own pay. Running costs come with each job: disposal, fuel, wear on the truck, any paid help and supplies. Here's the sheet's example, with the made-up numbers marked:

Sources for the table: listings,⁸ disposal,¹⁴ diesel,¹⁵ owners' prices.²¹

Break-even here means the business pays its bills and you, with nothing left over. Twenty-five a month sounds easy until you count the first winter. The Michigan plumber's 260,000 gallons in his first full year is about 17 pump-outs a month at 1,250 gallons each, and he already had plumbing customers asking.⁷ The fastest lever is price, not volume: at $500 the same sheet breaks even at 22. How to set that price, flat or per gallon, with lids, digging and disposal, is in how to price septic pumping.

State licenses and permits on top

Every state and county has its own say on who may pump and where the load goes. Three states where we track new septic licenses:

• Maryland. MDE still runs a registration: "any individual who provides on-site wastewater services" pays $150, renewed "every 2 years," and the county can add its own. MDE's FAQ answers the question about a county septic license and "a septage hauler license fee annually" with "Yes, the State law and regulations do not override any county or local requirements."¹⁶ The registration, the license the 2022 law calls for and its July 1, 2026 date, and what to do now are in Maryland septic license and registration.
• Delaware. Pumping takes a Class F liquid waste hauler license, which means an exam, a "valid State of Delaware Non-Hazardous Liquid Waste Transporters Permit" and "a $5,000 performance bond, or other form of security" on file with DNREC. Class F haulers sign a maintenance contract before pumping out a holding tank and send DNREC a copy within 15 days, and they file quarterly reports of the septage they remove.¹⁷ Delaware's sale rule, a pump-out and inspection before a home sale closes, is in the septic maintenance agreement template.
• Minnesota. State law says "a person may not design, install, maintain, pump, inspect, or provide service to a subsurface sewage treatment system without a license." The MPCA business license is "$200 fee for each license specialty area per year ($400 maximum)," with at least one certified individual per specialty, general liability of at least $100,000 and "a corporate surety bond of at least $25,000." Pumpers who thaw frozen systems with a boiler also need a boiler operator's license.¹⁸

Most of the money in this section is small next to the truck. The time isn't: exams, courses and a certified individual on the payroll don't happen in a week, so start them before the truck arrives. The Minnesota and Delaware rules are also in how to price septic pumping.

Buying a route instead

Search for how to start a septic business and most of what comes back is selling something. The top YouTube results include acquisition channels such as JackQuisitions and "How to Build a $100M Septic Pumping Business in 2025," and a much-upvoted Reddit post on buying a septic company (it promised "margins are 60%+ and the multiples are 2.5x") is the seventh in one author's series of industry deep dives.^{19, 20} A reply from someone who has bought three septic businesses is the useful part: "No one is paying 2.5x SDE on anything of size. 2.5x is one truck maybe 2 type of multiple. 3+ trucks is 4x EBITDA."¹⁹ By that buyer's account, a one- or two-truck business sells for no more than about 2.5 times its seller's discretionary earnings (the owner's profit plus pay for a year). That can beat building from nothing if the customer list is real, so ask for the pump-out records by address, not a revenue figure.

Where Deepsel fits

Deepsel is the field service software I build, and it doesn't run the truck side of this page. It won't track the loan, fuel, disposal receipts or manifests, plan a route, or tell you when you're near the weight line. Here's what it does for a pumping business. Pump-outs go on the schedule and get dispatched like any job, and the customer approves a quote and signs on screen. A per-gallon price goes on the invoice as a line with the gallons as the quantity, and the customer pays it by card. Each tank can be an equipment record at its address, with rows you name for the tank size, the lid location and the depth you dug last time, so the next pump-out starts with the lids found. Maintenance contracts on BAT units and holding tanks run in the service plans module on Pro: it keeps the ledger of visits owed against delivered, charges the card on the contract's schedule or sends a scheduled invoice, and sends a reminder by email when a covered visit comes due. Free covers 30 estimates and 30 invoices a month for your whole team, which holds the 25 pump-outs a month the break-even asks for; past 30 invoices a month you'd be on Pro at $29 a month with unlimited estimates and invoices (pricing).

Frequently asked questions

How much does it cost to start a septic pumping business?

The truck is most of it. On November 8, 2026, used septic trucks with 2,000 to 2,500-gallon tanks were listed at $75,000 to $94,000 at one Florida dealer, 1996 to 2013 trucks at $22,500 to $70,000 on Pumper's classifieds, and new 2,000 to 2,500-gallon trucks at $136,000 to $175,000. On top of the truck: commercial auto, general liability and pollution insurance, state and county licenses, and a few months of fuel and disposal before the work pays for itself. One pumper's company bought a used truck for $10,000 and fixed the pump itself.

Do you need a CDL to drive a septic truck?

Only if the truck is rated or actually weighs 26,001 pounds or more. Federal rules count the GVWR or the gross vehicle weight, whichever is greater, so a truck with a 25,999 lb sticker still needs a Class B CDL once a full tank puts it over 26,000 lb on the scale. If you need the CDL and the tank holds 1,000 gallons or more, you also need the tank vehicle endorsement, which is a knowledge test. The rule covers trucks that never leave your state.

How many gallons can a non-CDL septic truck carry?

Take 26,000 lb, subtract the empty weight from a scale ticket (driver, fuel and hoses included), and divide by at least 8.34 lb a gallon, what water weighs. A truck that weighs 14,000 lb empty can carry about 1,438 gallons and stay at 26,000 lb, whatever size its tank is. The cost sheet's CDL tab does the arithmetic for your truck.

How much does it cost to dump septage at a treatment plant?

Between about 2 and 9 cents a gallon at the five plants I checked on November 8, 2026: $20.50 per 1,000 gallons at Spotsylvania County, Virginia, 2.4 cents a gallon in Winston-Salem, $49.24 per 1,000 in Madison, Wisconsin, $67.27 per 1,000 at the Twin Cities' Metropolitan Council, and 9 cents a gallon in Raleigh. Several also charge a yearly permit or a monthly fee. A 1,250-gallon job costs $26 to $113 to dump at those rates.

How many pump-outs a month does a septic business need?

Divide your fixed costs a month, including your own pay, by what's left of each pump-out after disposal, fuel, wear and paid labor. The cost sheet's example (a $92,900 used truck, made-up insurance, $5,000 a month for the owner, a $450 pump-out) needs 25 a month, about 1.2 a working day. A Michigan plumber who added pumping pumped about 260,000 gallons in his first full year, roughly 17 jobs a month at 1,250 gallons each.
