ACI 350.3-06, "Seismic Design of Liquid-Containing Concrete Structures," provides essential procedures for calculating impulsive and convective forces acting on tanks during seismic events. It details hydrodynamic pressure formulas crucial for designing secure water treatment and storage infrastructure, though the standard has been updated in more recent versions.

The standard dictates when a tank must be anchored to its foundation versus when it can sit unanchored (gravity base). It defines the overturning moment ($M$) and base shear ($V$) specifically for circular and rectangular tanks.
