The standards for water tank inspections encompass protocols for assessment and maintenance, aiming to achieve expected safety standards. Organizations such as the National Fire Protection Association and the American Water Works Association develop detailed guidelines and specifications customized for each water tank and its specific purposes.
NFPA and AWWA: what are these Organizations?
The National Fire Protection Association (NFPA) is an international nonprofit organization dedicated to advancing fire and life safety. It develops and publishes codes and standards related to fire protection, including regulations for fire water storage tanks.
The American Water Works Association (AWWA) is a nonprofit organization representing the largest community of water professionals worldwide. It provides education, resources, and advocacy to promote safe water practices. Additionally, AWWA publishes standards and guidelines covering various aspects of water supply and treatment, including regulations for potable water storage tanks.
NFPA Standards for Panel Tanks
NFPA standards for fire water storage tanks are outlined in NFPA 22: Standard for Water Tanks for Private Fire Protection. Chapter 4 of NFPA 22 specifies general requirements, with subsequent chapters addressing specific types of water tanks. Compliance with these standards and specifications can lead inspection companies to obtain NFPA certification.
General Requirements:
NFPA standards for fire water storage tanks, as delineated in NFPA 22: Standard for Water Tanks for Private Fire Protection, establish various criteria and specifications aimed at ensuring the safety and reliability of these tanks. Here are key points derived from the general requirements:
- Capacity and Elevation: Tank size and elevation are determined based on specific property conditions.
- Water Sources: The water source supplying the tank must be sufficient and dependable, with consideration for future reliability.
- Tank Location: Tanks must be strategically positioned to protect both the tank itself and adjacent structures from fire exposure.
- Tank Materials: Acceptable materials for tanks include steel, wood, concrete, coated fabrics, and fiberglass-reinforced plastic.
- Workmanship: Tank manufacturers must adhere to specified requirements and deliver structures that demonstrate reliability under defined conditions.
- Plans: Contractors must submit stress sheets and plans for approval by relevant authorities to obtain building permits and licenses.
- Contractor Responsibility: Experienced contractors are accountable for ensuring all work is performed with precision and expertise. Tanks undergo water tightness testing upon completion before official inspection.
- Attachments to Tank Structures: Any attachments, such as signs or flagpoles, must be designed specifically for attachment to tank structures.
- Strength: Tank materials must be free of defects that could compromise their strength or performance.
- National Standards: Only tank materials meeting recognized national standards are permitted.
- Roof Standards: All tanks must include roofs, with OSHA-compliant standard railings installed around roof utility holes and other access points.
- Roof Vent Standards: Steel roofs, which are essentially airtight, require vents positioned above the highest water level, fitted with corrosion-resistant screens to prevent contamination.
AWWA Standards for Water Tank Inspection
The AWWA standards governing water tank inspections are detailed in AWWA D100: Standard for Welded Carbon Steel Tanks for Water Storage. This standard not only specifies design, fabrication, and construction requirements for potable water storage tanks but also provides guidance on maintenance and inspection protocols.
Similar to NFPA standards, the AWWA standard encompasses various specifications and guidelines covering different aspects of water tanks. This includes criteria for tank design, specifications for accessories, and recommendations for tank placement to ensure compliance with safety and quality standards.
Importance of Adhering to NFPA and AWWA Standards for Tank Inspections
Both NFPA and AWWA emphasize the critical importance of regular maintenance and inspections for water tanks, establishing minimum requirements for these activities. Their guidelines are essential for maintaining the integrity of water tanks and ensuring a safe and clean potable water supply for consumers.
It’s essential to recognize that these standards set by NFPA and AWWA represent minimum requirements and may not comprehensively cover all local jurisdictions. Local codes and regulations might impose additional requirements for the maintenance and inspection of water tanks, tailored to specific regional considerations and environmental conditions.
