• A. Treatment plant
• B. Distribution system
• C. Customer service lines
• D. Pumping station

Answer: (B)

Fire flow tests measure how much water can be delivered to a fire suppression operation through the water distribution system, at multiple points along that system. This helps determine available fire flow (in gpm) and retained pressures under flow conditions, so responders know whether there is enough supply to protect structures and where adjustments or improvements are needed. It’s about the network that delivers water to hydrants and buildings, not upstream treatment or a single facility. Upstream treatment plants supply water, but the test’s purpose isn’t to assess treatment capacity. A pumping station affects flow, but the test evaluates the broader distribution system’s ability to deliver fire water, not just one station. Customer service lines are smaller lateral connections to individual customers and aren’t used to gauge system-wide fire flow. Hence, the distribution system is the correct focus.
