The Benefits of Regular Panel Tank Inspections in accordance with NFPA and AWWA Standards

The standards for inspecting water tanks cover both the procedures for assessment and upkeep of water tanks and the anticipated safety levels resulting from these practices. Organizations like the National Fire Protection Association and the American Water Works Association establish comprehensive guidelines and specifications tailored to each water tank and its intended functions.

NFPA and AWWA: what are these Organizations?

The National Fire Protection Association (NFPA) is an international nonprofit organization dedicated to promoting fire and life safety. It formulates and publishes codes and standards concerning fire protection, including regulations for fire water storage tanks.

The American Water Works Association (AWWA) is a nonprofit group that represents the largest community of water professionals globally. It offers education, resources, and advocacy for the promotion of safe water practices. Additionally, the AWWA publishes standards and guidelines covering different aspects of water supply and treatment, including regulations for potable water storage tanks.

NFPA Standards for Panel Tanks

NFPA standards concerning fire water storage tanks are detailed in NFPA 22: Standard for Water Tanks for Private Fire Protection. Chapter four of NFPA 22 outlines general requirements, with subsequent chapters addressing specific types of water tanks. Compliance with these requirements and specifications can lead tank inspection companies to receive NFPA certification.

 General Requirements: 

NFPA standards for fire water storage tanks, as outlined in NFPA 22: Standard for Water Tanks for Private Fire Protection, establish various requirements and specifications to ensure the safety and reliability of these tanks. Here are some key points from the general requirements:

  1. Capacity and Elevation: Tank size and elevation are determined based on individual property conditions.
  2. Water Sources: The water source supplying the tank must be sufficient and reliable, with consideration for future reliability.
  3. Location of Tanks: Tanks must be positioned to shield both the tank and surrounding structures from fire exposure.
  4. Tank Materials: Permissible tank materials include steel, wood, concrete, coated fabrics, and fiberglass-reinforced plastic.
  5. Workmanship: Tank manufacturers are expected to adhere to specified requirements and deliver structures that demonstrate reliability under specified conditions.
  6. Plans: Contractors must provide stress sheets and plans for approval by the relevant authority for building permits and licenses.
  7. Tank Contractor Responsibility: Experienced contractors are responsible for ensuring all work is conducted with care and expertise. Once completed, tanks are tested for water tightness before official inspection.
  8. Attachments to Tank Structures: Any attachments to tank structures, such as signs or flagpoles, must be specially designed for that purpose.
  9. Strength: Tank materials must be free of defects that could compromise their strength or performance.
  10. National Standards: Only tank materials meeting the requirements of recognized national standards are permitted.
  11. Roof Standards: All tanks must have roofs, and OSHA-compliant standard railings must be installed around roof utility holes and other access points.
  12. Roof Vent Standards: Steel roofs that are essentially airtight require vents above the highest water level, equipped with corrosion-resistant screens to prevent contamination.

AWWA Standards for Water Tank Inspection

AWWA standards for water tank inspections are detailed in AWWA D100: Standard for Welded Carbon Steel Tanks for Water Storage. This standard outlines design, fabrication, and construction requirements for potable water storage tanks, along with guidance on maintenance and inspection procedures.

Similar to the NFPA standards, the AWWA standard list encompasses various specifications and standards for different aspects of water tanks. This includes design criteria, specifications for accessories, and recommendations for tank location to ensure compliance with safety and quality standards.

Importance of Following the NFPA and AWWA Standards for Tank Inspections

Both the NFPA and AWWA emphasize the importance of regular maintenance and inspections for water tanks, setting forth minimum requirements for these activities. Their guidelines play a crucial role in preserving the integrity of water tanks and guaranteeing a clean, potable water supply for users.

It’s important to note that the standards provided by these organizations represent minimum requirements and may not cover all jurisdictions comprehensively. Local codes and regulations may impose additional requirements for the maintenance and inspection of water tanks, reflecting specific regional considerations and conditions.

Wrapping Up

Securing water sources is paramount, and investing in water tanks is a wise choice. With proper care, water tanks can have a significantly extended service life.

Understanding the necessary steps to prolong the lifespan of your tanks is crucial. Following the standards established by reputable organizations with extensive research and expertise guarantees a continuous supply of clean, potable water.
