Underground hydrants are a critical part of South Africa’s firefighting infrastructure, providing essential access to water while being less visible and less prone to tampering. Unlike above-ground hydrants, they are installed below the surface and require additional equipment to operate.
At Woodlands Fire, we locally manufacture high-quality underground hydrants that meet industry standards, ensuring that firefighters and emergency responders have reliable access to water when it matters most.
1. Compact and Protected Design
- Installed below the surface, reducing the risk of vandalism or accidental damage.
- Typically covered by a hydrant box or manhole cover for added security.
2. Reduced Environmental Exposure
- Unlike above-ground hydrants, underground hydrants are not exposed to harsh weather conditions, prolonging their lifespan.
- Less likely to be affected by corrosion or UV damage.
3. Secure Access
- Hydrants are accessed using a standpipe, poker, and key, preventing unauthorized use.
- The system ensures controlled water flow, which is essential in fire emergencies.
4. Cost-Effective and Space-Saving
- Ideal for public areas, roads, and urban environments where space is limited.
- Designed for minimal obstruction while maintaining full functionality.
Each underground hydrant is designed with a specific outlet type, requiring a corresponding standpipe for connection to fire hoses. The three most common outlet types found in South Africa are:
- Recognized by its round-threaded connection.
- Used in various municipalities and private installations.
- Features a vee-shaped thread design, providing a secure coupling.
- Often specified in older hydrant systems.
- Uses a quick-locking mechanism instead of a threaded connection.
- Preferred in areas where rapid response is essential.
When selecting an underground hydrant, it’s important to ensure that the standpipe matches the outlet type for a proper and secure connection.
Left-Hand Closing (LHC) vs. Right-Hand Closing (RHC)
Underground hydrants are designed to open and close in different directions, classified as either left-hand closing (LHC) or right-hand closing (RHC):
- Left-Hand Closing (LHC) – The hydrant is closed by turning the key anti-clockwise (left).
- Right-Hand Closing (RHC) – The hydrant is closed by turning the key clockwise (right).
It is important to know the closing direction of a hydrant before use to ensure a quick and efficient response in emergencies.
Maintenance and Compliance with SANS 1475-2
Underground hydrants must be fully maintained in accordance with SANS 1475-2 to ensure they function properly when needed. Regular maintenance includes:
- Checking for leaks and corrosion in the hydrant body.
- Ensuring hydrant outlets are clean and accessible.
- Testing water flow and pressure to meet operational requirements.
- Inspecting and replacing seals or components as necessary.
At Woodlands Fire, we offer a full range of spare parts to keep underground hydrants in top condition, reducing downtime and ensuring compliance with safety regulations.
