Transforming Drainage

EDWRD – Tool Documentation

Evaluating Drainage Water Recycling Decisions (EDWRD) is a tool to estimate the potential benefits that result from capturing drainage agricultural water for reuse as irrigation, a practice referred to as drainage water recycling. This page contains various documentation and resources to help users utilize EDWRD. Materials such as tutorials and "how-to" guides are being developed and will be posted to this page. Users can access forms below to provide feedback, report an issue, and sign up to receive updates about EDWRD.
