What is the minimum diameter for the outlet baffle size?

The minimum diameter for the outlet baffle size is specified as 4 inches in the standards for sewage systems. This size is vital to ensure that effluent can flow freely from the tank while also preventing solids from escaping into the drain field, which is essential for the proper functioning of the system. A 4-inch diameter baffle allows for adequate hydraulic flow, minimizing the risk of clogs and ensuring that the sewage is treated effectively before reaching the soil absorption system. This size strikes a balance between preventing backflow and maintaining steady flow rates, thus contributing to the overall efficiency and longevity of the septic system. Adhering to the specified dimensions is crucial for compliance with regulations and for the health and safety of the environment and public.
