Firefighting Chapter 16 Hydrants Notes
Notes belong to Hannah Naffziger
Introduction
● Putting water on a fire cools and extinguishes it.
● Water is obtained from:
○ Municipal water systems
○ Static water sources
Rural Water Supplies
● Residents of rural areas usually depend on wells or cisterns to provide water.
● No hydrants in these areas, so water must be obtained from other sources.
Static Water Sources
● Static sources include:
○ Rivers or streams
○ Lakes, ponds, oceans
○ Canals or reservoirs
○ Swimming pools
○ Cisterns
Mobile Water Supply Apparatus
● Designed to carry large volumes of water
● Generally carry 1000–3500 gal
● May be used to pump water directly into attack engine
Portable Tanks
● Carried on fire apparatus
● Typically hold 600–5000 gal (2280-19,000 L) of water
● Tankers are used to fill the portable tanks.
● The pump operator drafts from the tanks.
● Dump valves on the tankers allow them to off-load up to 3000 gal (11,400 L) per
minute.
Water Sources
● Sources include:
○ Wells
○ Rivers or streams
○ Lakes
○ Reservoirs
● Many systems draw water from several sources.
Water Treatment Facilities
● Remove impurities
