Over the past decade and a half, the division has prepared a series of documents under the title "Utah State Water Plan," including a statewide water plan and an individual water plan for each of the state’s eleven major hydrologic river basins prepared through inter-agency and public outreach. This document is the latest in the "Utah State Water Plan" series and is intended to focus increased attention on the opportunities for water reuse in Utah. In many states throughout the nation, water reuse has proved to be an effective and safe means to help satisfy growing water demands. Many water suppliers in Utah recognize these successes and have taken steps to investigate and implement feasible projects. In addition to summarizing key advancements in the area of water reuse throughout the U.S., this document chronicles the existing and proposed projects in Utah. It also discusses the water quality and water rights requirements for such projects, and addresses other important issues such as human health, environmental impacts, economics and project funding. This document should be a valuable resource for Utah water and wastewater managers as well as other parties interested in water reuse. The Division of Water Resources also hopes this document will assist the Legislative Task Force Studying Water Issues as it addresses important water reuse issues. In addition to the printed form of this document, the Utah Division of Water Resources has made a “pdf” version available on the Internet. This can be accessed through the division’s home page at: www.water.utah.gov. v Table of Contents vi Table of Contents TABLE OF CONTENTS ACKNOWLEDGMENTS ................................................................................................................................. iii PREFACE............................................................................................................................................................v LIST OF FIGURES .......................................................................................................................................... xii LIST OF TABLES............................................................................................................................................ xii EXECUTIVE SUMMARY ...............................................................................................................................xv Chapter Page 1 INTRODUCTION TO WATER REUSE......................................................................................................1 Purpose and Content of this Document...................................................................................................1 What is Water Reuse?.............................................................................................................................2 Why is Water Reuse Needed?.................................................................................................................3 How Can Water Reuse be Applied?
