What is a Fire Water System?

A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected. Although historically only used in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price. Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings completely protected by fire sprinkler systems, over 96% of fires were controlled by fire sprinklers alone.

A firewater system generally has four main sections:

1. A supply of firewater. This can come from storage tanks, a firewater lagoon, or a natural body of water such as the sea or a lake or river.

2.A pumping system that provides a sufficient flow of water to extinguish the fire.

3.A header network of pipes, often in the form of a ring main that transfers the water from the pumps to the fire.

4.Hydrants, nozzles, sprinklers, or other local devices for directing the firewater to the location of the emergency.
