Sprinkler tank sizing vs fire water tank sizing
Understand the difference between sprinkler tank sizing, fire water storage, hose allowance, hydrant demand, and fire pump planning.
Short answer
Sprinkler tank sizing starts with sprinkler density, design area, hose allowance, and duration. Fire water tank sizing may include sprinkler demand, hose reels, hydrants, usable volume, refill rate, and local civil defense requirements.
Use sprinkler flow tools to estimate the demand basis, then use the fire water tank calculator to convert that demand into storage volume. Final approval still needs authority and hydraulic calculation review.
