Each type may be governed by a particular set of Department of Transportation regulations, so it’s a good idea to ensure compliance/certification when considering a purchase.

Key Tank Truck Features

Tank trucks are cab and chassis trucks upfitted with tanks specific to their intended use. Some, like asphalt or chemical tank trucks, may also be equipped with related equipment, such as a spray bar for asphalt application or a pumping mechanism that provides a safe, approved way to load the tank or access the chemicals within.

The tanks are often constructed from application-specific materials, such as aluminum, high-density plastic, or steel, to preserve liquids or prevent leaks. Some are equipped with internal bulkheads that allow the transport of more than one substance, and others have internal baffles that prevent surging that may unbalance a truck and cause it to tip during a turn.

Gas & Fuel Tank Trucks

Gasoline and fuel tank trucks typically transport fuel over long distances to make deliveries to filling stations, farms, and other destinations. Some models have a bulk tank that holds a single type or grade of fuel, while others have compartmentalized tanks that can hold different fuel grades.

When fuel trucks deliver gasoline to a storage tank at a filling station, operators typically connect both a fuel hose and a vapor recovery hose; the latter reduces emissions by carrying vapors from the storage terminal to the tank truck. These trucks can also be used for refueling purposes at airports.

Septic Tank Trucks

Septic tank trucks are designed primarily to clean out the contents of a septic tank and are fitted with vacuum pump systems and tanks for transporting waste. In addition to septic tanks, these vehicles are often used to clean out sewer pump stations and portable toilets. 

These trucks use suction hoses and vacuum systems to pump feces, sludge, and wastewater out of underground reservoirs into the tank for transport to a wastewater treatment facility, where the water may be processed and used for other applications, such as to irrigate and fertilize crops, for example.

Vacuum & Industrial Tank Trucks

Vacuum and industrial tank trunks are used by businesses, municipalities, government agencies, and others to collect and remove human and animal waste, grease, sewage, spills, soil, rock, sand, water, and other materials. These versatile vehicles often include water tanks, pipes, and high-pressure spray hoses used to break down clogs and debris that may impede material removal.

Vacuum and industrial tank trucks are used across construction sites, livestock operations, oil and mining operations, sewer and septic systems, and more. Some models are designed specifically for collecting hazardous materials, while others are geared more toward hydro-excavation applications, such as drilling holes, trenching, and removing the resulting debris and water.

Water Tank Trucks

Water tank trucks deliver large volumes of water and are used for jobs like dust suppression, fire suppression, power washing, potable water delivery, road cleaning, and soil compaction. Water trucks are often equipped with components like a water cannon or a spray system designed to suit a particular job. When suppressing dust at mining and quarry sites, for instance, water trucks might use dribble bars or sprayers for ground-level application.
