When should grease traps be cleaned according to best practices?

Cleaning grease traps at 75% of their grease retention capacity is considered best practice because this threshold ensures that the trap can effectively separate grease from wastewater. Once grease accumulates beyond the 75% capacity, the trap's efficiency diminishes. Overfilled traps can lead to grease bypassing the system, potentially causing clogs and reducing the overall effectiveness of wastewater treatment. Maintaining the trap at this level helps to ensure compliance with local regulations, prolongs the life of the grease trap, and reduces the risk of costly plumbing issues down the line.

In essence, by adhering to this 75% mark, operators can optimize the performance of their grease traps, ensuring that they adequately capture fats, oils, and grease before these substances can enter the municipal sewage system. Consequently, this practice not only supports the operational efficiency of the system but also contributes to environmental protection efforts by minimizing the impact of greasy discharges on wastewater treatment facilities.
