Septic Truck for Sale: Matching Tank Size to Your Route

A 1,200-gallon septic truck suits lighter routes and tight access, while a 6,000-gallon build suits heavy collection with fewer trips to the disposal site. Choose the size that covers your typical day, then confirm the loaded weight against your chassis rating.

Tank capacity	Best fit	Water-equivalent load
1,200 to 2,000 gallons	Lighter routes and tight access	10,008 to 16,680 lb
2,500 to 4,000 gallons	Mixed residential and commercial routes with fewer disposal trips	20,850 to 33,360 lb
5,000 to 6,000 gallons	Heavy collection and high-volume work	41,700 to 50,040 lb

Water weighs 8.34 pounds per gallon, so a full 1,200-gallon tank carries about 10,000 pounds of liquid and a full 6,000-gallon tank about 50,000 pounds. Septage can weigh more than water, and the chassis rating sets the real limit. The team confirms chassis compatibility before the build starts.

Tank Size and the Federal Tank Vehicle Line

Federal rules treat a commercial motor vehicle that carries tanks over 119 gallons each, with 1,000 gallons or more of combined capacity, as a tank vehicle, and CDL drivers of tank vehicles need a tank endorsement.

These septic packages start at 1,200 gallons, so they sit above that line. Operators who want to stay below it can look at a 999-gallon slide-in unit.

Licensing also depends on the vehicle weight rating and state rules, so confirm requirements with your licensing agency before you choose a tank size.

Septic Truck for Sale FAQs

What size septic tank trucks does KeeVac manufacture?

KeeVac manufactures septic tank truck packages from 1,200 gallons to 6,000 gallons, depending on chassis capacity and your route requirements. Smaller builds suit tighter routes, and larger builds suit heavy collection with fewer trips to the disposal site.

What materials are used in KeeVac septic truck tanks?

Septic truck tanks are fabricated from 5454 aluminum, which resists corrosion and gives a strong structure at a lower weight, so more of the chassis rating is available for payload.

Can I customize my septic vacuum tank package?

Yes. You can configure inlet and outlet sizes, lighting packages, pump systems, heated valves, hitch options, and add-ons such as pressure washers and jetter-ready features.

What pump brands are available for KeeVac septic tank trucks?

KeeVac offers pump packages featuring Masport, Fruitland, Jurop, and NVE, along with rotary vane and tri-lobe blowers. The team matches the system to your tank capacity, hose runs, and service conditions.

Do KeeVac septic tank packages come with a warranty?

Yes. KeeVac septic tank packages include a 7-year no-leak manufacturer defect warranty on the tank and typically a 1-year warranty on pumps.

Which chassis brands can KeeVac septic tank packages be mounted on?

KeeVac septic tank packages are commonly mounted on Kenworth, Freightliner, Mack, Peterbilt, Western Star, and other commercial chassis brands.

Can KeeVac build a septic tank package for a chassis I already own?

Yes. Include your chassis make, model, and frame details with your quote request so the team can confirm tank size, mounting, and pump options for that chassis.

What is the difference between a septic pump truck and a septic vacuum truck?

The names describe the same equipment: a truck with a sealed tank and a vacuum pump that pumps out septic tanks and hauls the waste. Septic pump truck, septic pumper truck, septic vacuum truck, and septic tank truck are used interchangeably.

How much does a septic truck cost?

The price depends on tank size, the pump package, options such as heated valves or jetter-ready features, and the chassis. Request a quote with your chassis, tank size, and pump preference to get exact pricing for your build.
