Although written specifically for pedestal water towers, ACI 371R-16 has become a touchstone for all liquid-containment structures, including below-grade reservoirs, clarifiers at treatment plants, and even secondary containment for industrial chemicals. Engineers often pair it with ACI 350 (which covers environmental engineering concrete structures), but 371R-16 is valued for its focused, practical guidance on elevated tanks—a niche but high-risk structure type. | Standard | Scope | Approach | Key

The guide warns against the common mistake of using standard formwork designed for walls. Silos require specialized curved formwork or slipforming to maintain circularity, as out-of-roundness > 1% of diameter can double the predicted hoop stresses. Engineers often pair it with ACI 350 (which

Through interviews with senior engineers who have applied the document , several recurring mistakes have been identified:

The report is structured to follow a tank’s lifecycle: from initial analysis through final construction. Three core themes dominate its content:
