What should piping trench liners be sloped toward in order to facilitate the detection of leaked product?

Piping trench liners should be sloped toward a collection point within the lined area to facilitate the detection of leaked product. This design ensures that any leaks from the piping system drain towards a designated area where liquid can accumulate, making it easier to monitor and identify leaks.

The collection point serves as a central location for detection systems to be installed, allowing operators to quickly assess leaks and take appropriate corrective actions. By directing any leaked product towards this point, it enhances safety measures and helps prevent environmental contamination. This proactive approach is essential in complying with environmental regulations and ensuring the integrity of the underground storage tank system.
