NFPA 22 Standard for Water Tanks
NFPA 22, which is the standard for water tanks for private fire protection, offers thorough advice on how to plan, construct, put in place, and maintain these tanks and their associated gear.
The 2023 edition introduces several updates to improve its usability and align it with current practices. Key revisions include: eliminating redundant sections for better clarity, updating guidance on external forces such as wind, snow, and live loads to conform to other standards and replace outdated design methods, modifying tank sizing regulations to ensure pump suction pressure is factored into the design, updating tank construction details to meet new and relevant industry standards, adding more provisions for valves to simplify maintenance, specifying clearances between fill lines and suction pipes to prevent fire pump cavitation, and correcting minor issues like unit conversions. Additionally, all citations have been updated to reflect the latest codes and standards.
