Purpose and Scope 

This Engineering Practice is a guide to engineers, technicians and farmers designing and operating systems to collect runoff from surface irrigated fields for subsequent use on the same or other fields. Tailwater runoff reuse is most commonly applied to furrow irrigation, but the concepts apply to any irrigation system that produces runoff and to the reuse of subsurface drain water. This Engineering Practice is not intended to serve as a complete set of design criteria and specifications for construction. All systems should be designed in conformance with local regulations (i.e., construction, safety, and water quality standards).
