What is the purpose of a liquid collection point in a UST system?

The purpose of a liquid collection point in a UST (Underground Storage Tank) system is to gather condensate. This is important because, during the operation of the UST, vapors can condense into liquid form due to temperature changes or other factors, especially in systems that involve the storage of fuel and other volatile liquids. By having a designated point to collect this condensate, it can be effectively removed from the system, preventing potential issues such as corrosion, contamination, or disruptions in the flow of the primary liquid being stored.

The liquid collection point helps manage and maintain the integrity of the UST system by ensuring that excess liquids that can accumulate and cause problems are properly dealt with. It supports the overall safety and efficiency of the UST operation, as regular removal of this condensate can prevent hazardous conditions and ensure compliance with regulations. Other options like enhancing flow, collecting excess vapor, or facilitating pressure testing pertain to different functions within the UST system and do not directly align with the specific role of gathering condensate.
