The fill rate of an MWS is determined by

• A. Individual jurisdictions
• B. Hose diameter
• C. Tank size
• D. Pump horsepower

Answer: (A)

Fill rate for an MWS is governed by local rules and procedures. Different jurisdictions set how fast water can be loaded into or offloaded from the truck to protect hydrants and the water system, ensure safety at fill sites, and coordinate with other users of the water supply. Hardware factors like hose diameter, tank size, or pump horsepower influence how water can move or how much you can carry, but they don’t by themselves establish the permitted fill rate. The local SOPs and water authority guidelines determine the allowable fill rate, which is why the correct choice is that individual jurisdictions control it.
