Principles of Exterior Drainage - NDS Stormwater Management

Chapter 5: Subsurface Drainage Design NDS Principles of Exterior Drainage - Short Course 29 The pipe size required to drain a certain acreage depends on the pipe gradient, since an increase in gradient results in a greater velocity of flow and permits the pipe to drain a larger area.Pipes are placed at constant gradients,or variable gradients with

Diagrams show test load applied to grates through a 9" x 9" (225 x 225mm) test block. At 4" and 8" widths, grate is NOT tested - the load is taken by supports rather than grate - results from these tests are questionable. Only at 12" and wider is grate being tested and relevant results will be provided.
