What is the primary function of a grease trap in a septic system?

The primary function of a grease trap in a septic system is to separate grease from water-carried waste. This is crucial for proper septic system function because grease, when mixed with wastewater, can create clogs and lead to system failure. A grease trap is designed to intercept and capture fats, oils, and grease (FOG) before they enter the septic system or sewage line. By allowing these substances to cool and solidify, the grease trap ensures that they are removed from the flow of water, thus preventing potential issues further down the system. This separation helps maintain the efficiency of the entire septic system and reduces the risk of costly repairs associated with grease buildup in pipes and tanks.
