Buildings with a basement at more than 10 m below ground level, basement should be equipped with wet or dry fire mains.
The Dry Riser pipe is maintained empty of water.
A Dry Riser comprises of an inlet connection, which is an external access point at ground level through which water can be pumped from the fire engines to outlet valves located on every floor.
Air Release Valve located on the top of the system to expel the air and a Drain Valve to completely drain the riser after use.
