Effluent from a grease trap should be directed to the septic tank rather than directly to the field lines because field lines are part of the drainage system meant to distribute treated wastewater into the surrounding soil. The primary function of a grease trap is to separate fats, oils, and grease from the wastewater before it enters the septic tank. If the grease trap effluent were to bypass the septic tank and go straight to the field lines, it could disrupt the balance of the septic system and lead to potential clogs, poor drainage, and environmental contamination. The septic tank is designed to further treat this wastewater, allowing solids to settle and anaerobic bacteria to break down the waste, ensuring that only relatively clean effluent is sent to the field lines for distribution. By sending effluent from the grease trap to the septic tank first, it ensures proper treatment and lowers the risk of system failure. This further emphasizes the importance of treating wastewater appropriately before it enters the drainage components of the system.
