This chapter discusses water supply systems used by firefighters. It covers the different types of water sources and supply systems, including underground piping and storage tanks. It also describes the valves used to control water flow and the different types of fire hydrants, their locations, and how to inspect and operate them. Alternative water supply methods for rural areas are discussed, such as water shuttles using portable tanks and relay pumping from nearby sources. The chapter emphasizes the importance of firefighters understanding local water supply systems and how to access water for firefighting.

Use of self-filling vacuum mobile apparatus has increased. 14–40
Relay pumping is used when the water source is close enough to the fire scene. 14–41
REVIEW QUESTION What are the common operations for accessing rural water supplies? 14–42
• Because water is the primary fire extinguishing agent used by firefighters, and because fires often occur considerable distances from major water sources, fire departments must develop ways to transport the available water from its source to the place it is needed. Summary 14–43 (Cont.)
• Firefighters must be familiar with the water supply systems in their response areas. • They must know about water sources, pumping systems, gravity systems, and the system of underground water mains used to distribute the water. Summary 14–44 (Cont.)
• They must also know how to inspect, maintain, and operate the fire hydrants in their jurisdictions. Summary 14–45
Operate a hydrant. This objective is measured in Skill Sheet 14-I-1. Learning Objective 6 14–46
