What is the required length consistency for both primary and secondary piping between containment sumps?

The requirement for both primary and secondary piping in underground storage tank (UST) systems to have continuous lengths between containment sumps is critical for ensuring the integrity and reliability of the system. Continuous piping helps to minimize the potential for leaks and failures by reducing the number of joints and connections that can become points of failure due to environmental stress, corrosion, or mechanical wear.

When primary piping is continuous, it allows for a seamless transport of fuel or other substances from the tank to the dispensing point, while also ensuring that any monitoring systems put in place can operate effectively over the uninterrupted length of the pipe. The same principle applies to secondary piping, which is crucial for containment and must also maintain a continuous path to effectively manage any leaks or spills.

Using isothermal principles and proper installation techniques, continuous piping vastly improves the reliability of leak detection systems and maintains the necessary structural integrity within the containment areas. Regular inspections and certifications rely on this continuity to ensure compliance with safety and environmental regulations, thereby protecting both the environment and public health.
