Why do trucks spray water?

Have you seen big trucks on the road spraying water? They do this for many good reasons! Let’s find out why.

What Are Water Spraying Trucks?

Water spraying trucks are big vehicles with water tanks. They spray water on roads, in the air, or other places. These trucks help keep our cities clean and safe.

Main Reasons Why Trucks Spray Water

1. Dust Control

The most common reason trucks spray water is to keep dust down. This happens a lot in:

• Construction sites
• City streets
• Places with lots of pollution

In China, they use many trucks to spray water in the air to reduce dust. Some people in Singapore wonder why they don’t do this there too, since they have problems with volcanic ash and dust.

2. Road Anti-Icing

Did you know? Some trucks spray water that has salt in it! This is not just water – it’s a special mix.

The Minnesota Department of Transportation uses 800 trucks for this job. These trucks take:

• 1-2 hours to finish routes in cities
• Up to 8 hours in the country

People often ask: “Why spray water on a clear day?” The answer is that they are anti-icing. They put salt water on roads so ice and snow won’t stick to the road later.

How Water Spraying Works

Let’s see how these trucks work:

Part	What It Does
Water Tank	Holds the water or special mix
Pumps	Push the water out
Spray Nozzles	Control how the water comes out
Controls	Let the driver decide when to spray

Types of Water Spraying Trucks

There are many kinds of trucks that spray water:

1. Dust Suppression Trucks

These help keep dust down at construction sites and on dirt roads. They make the air cleaner for everyone to breathe.

2. Road Maintenance Trucks

These trucks spray salt water on roads in winter. They help keep ice from forming.

3. Street Cleaning Trucks

Some trucks clean streets by spraying water and then sweeping up the dirt.

4. Multi-Purpose Trucks

New trucks can do many jobs at once! Some can sweep and spray water at the same time.
