Guide to Creating a Community- Scale Urine Diversion Program
This document describes the work of the Rich Earth Institute (Rich Earth) in detail, primarily to support those seeking to move this work forward in their own regions. We cover the process of starting up a community-scale urine diversion program (UD program) and key elements of its operation. Throughout the document we also reference the UD program Toolkit, where we have publicly made available a host of open source documents, presentations, and other materials to support those starting a UD program. Please do let us know if you start a UD program! We’d love to hear what happens, and assist if we can.
