What is the minimum size and grade for a gravity flow sewer line on city right-of-way?

4 inch and a grade of 0.25 percent
6 inch and a grade of 0.50 percent
8 inch and a grade of 1.0 percent
10 inch and a grade of 1.5 percent

The correct answer is: 6 inch and a grade of 0.50 percent

The correct choice highlights that a minimum sewer line size of 6 inches is commonly specified for gravity flow systems in urban settings, which contributes to effective wastewater management and minimizes the risk of blockages. Additionally, the requirement for a grade of 0.50 percent ensures that there is sufficient slope to maintain appropriate flow velocity, preventing sediment buildup and ensuring efficient transport of wastewater. These specifications reflect industry standards aimed at ensuring functionality, reliability, and compliance with public health regulations. Larger sizes and steeper grades may be found in various contexts, but the selected answer provides a balanced and effective choice for typical city infrastructure.
