Raven Tanks: Embracing Environmental Excellence with Secondary Containment Systems

In various industries, Above-Ground Storage Tanks (ASTs) are indispensable for storing vital liquids like water, petroleum, and chemicals. However, the potential for leaks and spills poses significant risks to the environment, human health, and business viability. To proactively address these concerns, the strategic implementation of secondary containment systems becomes crucial. 

In this insightful blog, we dive into the environmental benefits of integrating secondary containment solutions for your ASTs, underscoring the importance of environmental protection and regulatory compliance. Exploring various systems such as impervious liners, double-walled tanks, and berms, we highlight their role as additional barriers to prevent spills, minimizing the risk of soil, water, and air contamination. 

Lastly, we showcase how Raven Tanks, a distinguished provider of tank design, installation, repairs, and maintenance, can aid businesses in crafting, installing, and maintaining secondary containment systems for their ASTs. Leveraging their expertise, Raven Tanks contributes to environmental protection while helping businesses mitigate risks and liabilities associated with tank leaks and spills. 


Types of Secondary Containment Systems 

Several types of containment solutions serve as a crucial line of defense against AST leaks and spills: 


  • Impervious Liners: Crafted from materials like polyvinyl chloride (PVC) or high-density polyethylene (HDPE), impervious liners create a physical barrier, preventing liquids from infiltrating the soil or groundwater beneath the tank. 
  • Double-Walled Tanks: Featuring an additional outer wall surrounding the primary storage container, double-walled tanks contain any leaks within the secondary enclosure, averting environmental contamination. 
  • Berms and Dikes: These raised barriers, constructed from earth, concrete, or steel, encircle the tank, creating a containment area to hold potential spills. Well-designed berms can hold a specific percentage of the tank’s volume in case of a leakage or rupture. 


Environmental Benefits of Secondary Containment Systems 

The implementation of secondary containment systems yields numerous environmental advantages: 


  • Preventing Soil Contamination: Containment barriers block direct contact between hazardous fluids and the ground, reducing the risk of soil contamination that could result in long-term environmental damage or hinder future land use. 
  • Safeguarding Water Sources: Containment systems protect surrounding water sources, such as groundwater, rivers, and lakes, from contamination caused by AST leaks or spills. This safeguards the health of ecosystems, wildlife, and human populations reliant on these resources. 
  • Reducing Air Pollution: By minimizing the release of volatile organic compounds (VOCs) from AST leaks, secondary containment systems can help combat air pollution and mitigate potential human health impacts. 
  • Encouraging Sustainable Practices: Implementing secondary containment systems highlights a business’s commitment to environmental protection and sustainability, promoting industry-wide adoption of responsible practices. 


Regulatory Requirements for Secondary Containment 

Adhering to regulatory requirements is essential for businesses operating ASTs: 


  • Containment Capacity: Regulations specify the minimum containment capacity of secondary containment systems, ensuring sufficient capacity to hold potential spills. 
  • Material Compatibility: Containment materials must be compatible with stored liquids, ensuring the continued effectiveness of the barrier. 
  • Inspection and Maintenance: Regular inspections and maintenance of secondary containment systems are required to guarantee their effectiveness, similar to the primary AST. 
  • Leak Detection: Certain regulations mandate the use of leak detection systems for immediate action in the event of a containment breach.
