How many water tanks can a single fire truck hold? And how much water can it hold per each tank?
How Many Water Tanks Can a Fire Truck Hold?
Have you ever seen a big red fire truck zoom down the street? These special trucks help put out fires! But how do they carry water? Let’s find out how many water tanks a fire truck can hold and how much water fits in each tank.

The Main Facts
Most fire trucks have one main water tank. This big tank holds all the water the fire truck takes to a fire. Some special fire trucks may have extra tanks for foam or other things that help put out fires.
How much water can a fire truck hold? Let’s look at the numbers:
| Fire Truck Type | Number of Tanks | Water Tank Size | What It’s Used For |
|---|---|---|---|
| Regular Pumper Truck | 1 main tank | 300-1,250 gallons (most have 500-750 gallons) | City fires, uses fire hydrants |
| Big Pumper-Tanker | 1 main tank + possibly extra portable tank | 1,000-3,000 gallons (main tank) + 2,000 gallons (portable tank) | Fires in places with no fire hydrants |
| Water Tanker Truck | 1 main tank | 1,000-5,000 gallons (some big ones hold up to 20,000 gallons) | Big fires or industrial accidents |
| Ladder Trucks | No tank or 1 small tank | 200-500 gallons (just for starting to fight fires) | Tall building rescues, helping people |
| Wildland Fire Truck | 1 small tank | 200-500 gallons | Forest and grass fires |
| Industrial Tanker | 1 main tank | 5,000-20,000 gallons | Construction sites, oil fields |
Different Types of Fire Trucks and Their Water Tanks
Fire Truck Water Tank Capacity
Regular Pumper
500-750 gal
Most common type, uses hydrants.
Water Tanker
1,000-5,000 gal
For areas with no hydrants.
Pumper-Tanker
Up to 3,000 gal
Combines pumper and tanker.
Ladder Truck
0-500 gal
Focus on rescue, not water.
Wildland Truck
200-500 gal
For forests and grass fires.
Industrial Tanker
5,000-20,000 gal
Construction, oil fields, big fires.
Regular Pumper Trucks
These are the most common fire trucks you see. They have one water tank that holds between 300 and 1,250 gallons of water. Most pumper trucks you see on the street carry about 500 to 750 gallons.
A pumper truck can spray water very fast – about 750 to 1,000 gallons every minute! That means they can empty their tank in just a few minutes.
These trucks work best in cities where they can hook up to fire hydrants to get more water when they run out.
Water Tanker Fire Trucks
Water tanker fire trucks are made to carry lots of water to places that don’t have fire hydrants. They have one big main tank that can hold between 1,000 and 5,000 gallons of water.
The smallest tanker fire trucks hold about 1,000 gallons. Medium-sized tankers hold about 2,000-2,500 gallons. These medium ones are good because they carry lots of water but aren’t too hard to drive.
Some really big industrial tankers can hold up to 20,000 gallons! But these are very special trucks not used for regular fires.
Pumper-Tanker Trucks
These trucks are a mix of pumper trucks and tanker trucks. They have one main water tank that can hold up to 3,000 gallons in some cases. They also have pumps to spray the water.
These trucks are perfect for areas that don’t have many fire hydrants because they can bring lots of water and also pump it onto the fire.
Sometimes these trucks also bring portable water tanks that can hold about 2,000 gallons. They set these up at the fire scene like a small swimming pool to hold extra water.
Ladder Trucks
Ladder trucks (also called fire trucks by some firefighters) have very small water tanks or no water tanks at all. If they do have a tank, it usually holds between 200 and 500 gallons of water.
These trucks focus on rescuing people and helping firefighters get to tall buildings. They have big ladders instead of big water tanks.
Wildland Fire Trucks
Trucks that fight forest fires usually have smaller water tanks that hold between 200 and 500 gallons. These trucks need to drive on rough roads, so they can’t be too heavy.
Why Don’t Fire Trucks Have More Tanks?
Fire trucks usually have just one main water tank for a few good reasons:
- Space – Fire trucks need room for other things like hoses, tools, and firefighters.
- Weight – Water is very heavy! One gallon weighs about 8.3 pounds. A truck with 1,000 gallons carries 8,300 pounds just in water!
- Simplicity – Having just one tank makes the pumping system simpler.
- Rules – There are rules about how much weight trucks can carry. Single-axle trucks can only carry about 2,000 gallons safely.
How Fire Trucks Get More Water
Since fire trucks can use up their water quickly, they need ways to get more water. Here’s how they do it:
- Connect to fire hydrants in cities
- Use natural water sources like lakes or rivers
- Set up portable tanks that other trucks can fill
- Get water from other fire trucks in a relay system
The National Fire Protection Association says firefighters need at least 150 gallons of water per minute from each hose to fight a house fire. Most fires need several hoses going at once, using 300 to 1,000 gallons every minute!
Fire Trucks vs. Fire Engines: What’s the Difference?
Many people get confused about the difference between fire trucks and fire engines:
- A fire engine (or pumper) carries water, hoses, and pumps to fight fires
- A fire truck usually has ladders and rescue equipment but no water tanks
However, many people call all firefighting vehicles “fire trucks” even if they’re technically fire engines.

Special Features of Fire Truck Water Tanks
Fire truck water tanks have some cool features:
- Baffles – These are walls inside the tank that stop the water from sloshing around when the truck turns.
- Tank level indicators – These show firefighters how much water is left in the tank.
- Quick dump valves – These let the truck empty water very fast into portable tanks.
- Fill ports – These let the truck fill up quickly from hydrants or other sources.
Why Water Tank Size Matters
The size of a fire truck’s water tank is very important:
- Big tanks (1,000+ gallons) are good for areas without fire hydrants
- Medium tanks (500-750 gallons) work well in suburbs with some hydrants
- Small tanks (300-500 gallons) are good for city trucks that can quickly connect to hydrants
Firefighters must pick the right truck for each area. A truck with too small a tank might run out of water before more help comes. A truck with too big a tank might be too slow or hard to drive on small roads.
Fun Facts About Fire Truck Water Tanks
- The water in a fire truck tank weighs more than the truck itself!
- Most fire trucks can spray all their water in less than 5 minutes at full power.
- Modern fire trucks can mix foam with water to make it work better on certain fires.
- Some fire trucks have heated tanks so the water doesn’t freeze in cold weather.
- A full 1,000-gallon tank weighs over 8,300 pounds – that’s as heavy as two cars!
What Kids Want to Know About Fire Truck Water
Kids often ask great questions about fire trucks and their water:
Q: Do fire trucks carry regular water?
A: Yes! It’s the same water that comes from your tap at home.
Q: Can a fire truck run out of water?
A: Yes, they can run out in just a few minutes when fighting a big fire.
Q: Where do they fill up the fire truck?
A: Usually from fire hydrants, but sometimes from lakes, rivers, or swimming pools if needed!
Q: How fast can they spray water?
A: Very fast! Up to 1,000 gallons every minute – that would fill a bathtub in just seconds!
In Simple Words
To make it super simple: most fire trucks have just one big water tank. The size of this tank depends on what kind of fire truck it is:
- Big water tankers: 1,000-5,000 gallons
- Regular city fire trucks: 500-750 gallons
- Ladder trucks: 0-500 gallons
- Forest fire trucks: 200-500 gallons
Fire trucks need to be ready to put out fires fast! They carry their own water, but they also know how to find more water when they need it.
Next time you see a fire truck, remember it’s carrying hundreds of gallons of water ready to keep you safe!
