PIPE SLOPE DRAIN

Description of Practice

A pipe slope drain is a pipe that is installed to convey surface runoff down the face of unstabilized slopes. It is used to minimize erosion on the slope face. Use of flexible piping is preferred.

Conditions Where Practice Applies

Pipe slope drains are used in conjunction with earth dikes. The dikes direct surface runoff to the slope drain, which conveys concentrated flow down the face of a slope. When the pipe slope drain is used to convey water down an unstabilized fill slope on a road construction project, the drainage area will be limited to 2 acres. When the pipe slope drain is used as an inflow protection device, the drainage may be up to 5 acres.
