What is an Underground Fire Hydrant?

Underground fire hydrants, also known as below-ground fire hydrants or buried fire hydrants, are fire hydrant systems where the main valve and water supply connection are located below ground level. Unlike the traditional above-ground fire hydrants that have a visible standpipe, underground hydrants are designed to be more discreet and aesthetically pleasing while still providing access to water for firefighting purposes.

Construction of a Fire Hydrant

The underground fire hydrant system typically consists of a buried water main that connects to the hydrant valve, which is housed in an underground chamber. This chamber is usually made of durable materials like cast iron or reinforced concrete to protect the valve and associated components from damage or freezing temperatures.

Types of Underground Fire Hydrants

Wet Barrel Hydrants

Wet barrel hydrants are the most commonly used type of underground fire hydrants. They have a visible above-ground outlet or nozzle connected to an underground chamber that houses the valve.

In wet barrel hydrants, the valve is always in contact with water, hence the term “wet.” This design allows for faster response during firefighting operations since water is readily available at the outlet. Wet barrel hydrants are typically used in areas with moderate to mild climates where the risk of freezing is low.

Dry Barrel Hydrants

Dry barrel fire hydrants are primarily used in regions with cold climates where the risk of freezing is high. Unlike wet barrel hydrants, the valve in dry barrel hydrants is located below the frost line, below the water level. This prevents water from continuously filling the barrel and freezing during cold weather conditions.

When firefighters connect their hoses to a dry barrel fire hydrant, they need to operate the valve, and water flows into the barrel, enabling access to the water supply. Dry barrel hydrants require additional time to open the valve and allow water flow compared to wet barrel hydrants.

Both wet barrel and dry barrel hydrants serve the same purpose of providing access to water for firefighting. The choice between the two types depends on the local climate conditions and the likelihood of freezing temperatures. Additionally, there are variations and specific designs within these two main types to accommodate the specific needs and requirements of different regions or fire departments.

Why Underground Fire Hydrants?

Aesthetically Appealing

Underground fire hydrants are designed to be more visually appealing and blend in with the surroundings. Their concealed nature helps maintain the aesthetic appeal of streetscapes, parks, and urban areas while still providing essential firefighting capabilities.

Saves Time for Firefighting

Underground fire hydrants are strategically placed throughout urban areas, ensuring that firefighters have quick and easy access to a reliable water supply. The readily available water source enables them to initiate firefighting operations without delay, saving crucial time in extinguishing the fire.

Provides High Water Flow

Another attractive feature is that they are designed to deliver a high volume of water at high pressure.

This allows firefighters to effectively and rapidly distribute water to extinguish flames and control the fire’s spread. The substantial water flow provided by these hydrants helps in achieving efficient fire suppression.

Discreetly Integrates with the Surrounding

The underground placement of fire hydrants allows them to blend seamlessly with the surrounding environment. This discreet integration ensures that fire hydrants do not obstruct traffic or create visual distractions, enabling a smooth and efficient response.

Keeps it Protected from Damage

Being less exposed, Underground fire hydrants are less susceptible to intentional damage, accidental collision, or vandalism.

The underground chamber protects the hydrant valve and associated components, reducing the risk of damage. This protection is a good way to keep the hydrants stay in functional condition, ready for immediate use during emergencies.

Offers Improved Safety

The concealed nature of underground fire hydrants minimizes the risk of accidents and injuries.

Above-ground hydrants can pose tripping hazards or become obstacles in busy areas, but with underground fire hydrants, these risks are significantly reduced. The enhanced safety allows firefighters to focus on their firefighting tasks and navigate the scene more efficiently.

Exhibits Weather Resilience

Underground fire hydrants are less prone to extreme weather conditions, such as freezing temperatures.

By being located below ground, they are protected from frost and ice buildup that can hinder their operation. This weather resilience ensures that the hydrants remain functional and ready for use in all seasons, improving overall fire response efficiency.

Maintenance accessibility

While underground fire hydrants may require regular maintenance, the access points, and chambers are designed to be easily accessible for inspections, repairs, or valve operations. This ensures that the hydrants remain in optimal working condition.


In conclusion, underground fire hydrants serve as crucial assets for efficient fire response. They provide immediate access to a reliable water supply, enabling firefighters to connect hoses and initiate firefighting operations swiftly.
