Water storage tank liners can last for several years, especially with advancements in technology and high-quality water treatment. Typically, these liners have a lifespan ranging from three to five years before replacement is necessary to ensure the continued preservation of uncontaminated and well-protected water inside the tank.
The National Fire Protection Association (NFPA) and the American Water Works Association (AWWA) are two organizations that provide comprehensive information and strict guidelines for the maintenance, inspection, and installation of water tanks.
In this blog post, we will closely examine the expectations outlined by these two prominent industry standards organizations, NFPA and AWWA, regarding panel tank maintenance. We will explore the risks associated with a compromised liner, including contamination and structural damage, and discuss the implications for the environment, individuals using the stored liquids, and your company’s financial performance.
The Importance of Liner Integrity in Panel Tank Maintenance
The integrity of water tank liners is paramount for two primary reasons: (1) preventing leaks or cracks, and (2) maintaining the structural integrity of your water tank.
Preventing Leaks or Cracks
Leaks in your water tank may not always result in catastrophic consequences for its contents. However, having a tank liner provides an opportunity to address any necessary repairs to uphold the tank’s integrity.
When installed properly, a tank liner ensures that the water inside remains secure and unaffected by external factors, even in the event of a crack.
Maintaining the Structure of Your Tank
It’s also crucial to protect your tank’s structure from water, as sometimes, the tank’s contents themselves contribute to the deterioration of its structural integrity, leading to leaks and cracks.
Therefore, installing water tank liners helps to extend the lifespan of a structurally sound water tank, ensuring the continued containment of water over time.
Maintaining Panel Tanks According to NFPA and AWWA Standards
Adhering to NFPA and AWWA standards enables operators to detect and resolve potential issues before they escalate into major problems.
Here’s a checklist to help you get started:
- First and foremost, thoroughly inspect the exterior of the panel tank for any signs of damage, such as cracks or rust. Any identified damage should be promptly repaired to prevent further deterioration and potential leakage.
- Next, examine the interior of the panel tank for any signs of corrosion or damage to the liner. The liner is crucial in preventing contamination and maintaining the quality of the water supply.
- Remove any accumulated sediment or debris from the panel tank using a cleaning solution that meets AWWA standards. This ensures that the water supply remains free from impurities that could compromise its quality.
- Inspect the structural components of the panel tank, including the bolts and nuts securing the panels, for any signs of wear or damage. Promptly address any identified damage through repair or replacement to uphold the stability and integrity of the panel tank.
- Check the condition and proper usage of coatings and liners. Address any damage to these coatings or liners promptly to prevent contamination and maintain the safety and quality of the water supply.
- Verify the installation and functionality of overflow and vent pipes. These components are essential for preventing overflows or underflows, which could lead to water contamination or other safety hazards.
- Finally, ensure that all maintenance and repair activities are thoroughly documented in accordance with NFPA standards. Keeping detailed records of all maintenance and repairs allows operators to promptly identify potential issues and address them while ensuring compliance with safety standards.
