Static water source is defined as

• A. A water source produced under pressure by a municipal network
• B. A water source such as a pond, river, or stream not under pressure
• C. A pressurized reservoir used for firefighting
• D. A pumping station supplying water to high-rise buildings

Answer: (B)

Static water source means a body of water that is not under pressure; water isn’t supplied through a pressurized system, so you must draw and pressurize it yourself to use it for firefighting. A pond, lake, river, or stream fits this definition because they sit at atmospheric pressure and rely on pumps or gravity to create the needed pressure in your hose lines. The other options describe sources that are already pressurized or actively delivering water under pressure—such as a municipal network, a pressurized reservoir, or a pumping station—so they are not static.
