How to Calculate the Hydraulic Grade Line

WebIf the hydraulic grade line does not rise above the top of any manhole or above an inlet entrance, the storm drainage system is satisfactory. If the HGL rises above these points, blowouts will occur through manholes and inlets. Pipe sizes or gradients can be increased as necessary to eliminate such blowouts. Web6 apr. 2024 · This is called the hydraulic grade line, and, conveniently, it represents the height the water would reach if you were to tap a vertical tube into the main pipe.
