Underground Hydrant
An underground hydrant, also known as a flush hydrant or ground hydrant, is a valve installed below ground level used to draw water from the public supply network. These hydrants are essential for fire departments, providing a reliable and rapid water supply for firefighting and emergency operations.
Types of Underground Hydrants
- Standard underground hydrants: Designed for general use, offering dependable water access for firefighting.
- Frost-proof underground hydrants: Engineered for cold climates to prevent water from freezing within the hydrant system.
- Quick-connect underground hydrants: Allow fast and easy hose and equipment connection, improving response time.
- Above-ground/underground hydrants: Partially above and below ground, offering similar functionality to fully underground models.
Advantages of Underground Hydrants
- Reliable water supply: Provide consistent and dependable water access for fire and rescue services.
- Space-saving: Installed below ground, they do not obstruct the streetscape and are protected from damage.
- Frost resistance: Special frost-proof models ensure year-round readiness.
- Durability: Made from robust materials, they withstand weather changes and mechanical stress.
- Easy access: Quickly accessible and operable by fire crews during emergencies.
