What is the required minimum diameter for a sewer main in Georgia?

In Georgia, the minimum diameter for a sewer main is established to ensure adequate capacity for the safe and efficient transportation of wastewater. A diameter of 4 inches is the standard minimum, as it can effectively handle the expected flow rates and prevent blockages that could occur if the diameter were smaller.

Choosing a diameter of 4 inches accommodates the necessary volume of sewage from multiple fixtures and minimizes the risk of stagnation or backflow issues that could arise from inadequate pipe size. Larger diameters, while sometimes used for larger systems or specific situations, are not mandated as a minimum. Therefore, adhering to the 4-inch requirement provides a balance between cost-efficiency and functionality in the plumbing infrastructure. This standard is reflected in the plumbing codes and regulations to ensure public health and safety.
