Sloped Drain POLLUTANTS ADDRESSED: Sediments
ALTERNATIVE MANAGEMENT MEASURES Detention Basin Erosion Control Fabric Irrigation System, Tailwater Recovery
DESCRIPTION: A sloped drain is a pipe to convey water from one elevation to a lower one without erosion.
LOAD REDUCTION MECHANISM: Sediment Reduction – Because the water conveyed by the drain does not flow directly over the land, erosion is prevented and thus sedimentation does not occur.
PERMITTING REQUIREMENTS: Contact county representative
LAND USE CLASSIFICATION: Construction sites Agricultural lands Mining areas
POTENTIAL TREATMENT AREAS: Agricultural Lands Developed Lands
ADDITIONAL BENEFITS: Water is directed to areas of need.

PLANNING AND IMPLEMENTATION: Sloping drains should be engineered with enough capacity to carry expected flows. If not, water will flow around them creating erosion and threatening the drain. Inlets should regularly be cleared of debris.
