Guide to calculating Falls & Gradients in Drainage

A back drop manhole is used in areas where the surface level slopes as shown below. If the underground sewer pipe is to stay below ground it must follow the average gradient of the slope. This invariably means that the pipe gradient becomes too steep, resulting in the solids being left stranded in the pipe causing a blockage.

Principles of Exterior Drainage

There are three basic forms of drainage control on a steep slope: above ground drainage diversion above the cut slope area; sub-surface drainage within the slope; and pipe drainage from within the steep slope,primarily for draining active seepage such as springs. By far the most beneficial and effective of these drainage techniques is the
