When considering onsite wastewater systems, what is a critical factor for a grease trap?

In the context of onsite wastewater systems, the net liquid capacity of a grease trap is a critical factor because it determines how much wastewater the trap can effectively handle before reaching its maximum capacity. Grease traps are designed to intercept and separate grease and oils from wastewater to prevent them from entering the sewage system, which can lead to blockages and damage.

The net liquid capacity ensures that the grease trap can accommodate the expected volume of wastewater generated by the specific application, such as a restaurant or commercial kitchen, where grease production is significant. If the capacity is inadequate, the trap will overflow, leading to potential health hazards, environmental issues, and regulatory non-compliance.

While the location of installation, type of waste processed, and construction materials are relevant factors in the design and function of a grease trap, it is the net liquid capacity that fundamentally influences its effectiveness and the overall operation of the onsite wastewater system. Proper sizing based on anticipated load is essential for maintaining a functional system that effectively mitigates grease-related problems.
