Printed on Recycled Paper DOC NO. 20548303 Twenty- Fourth ANNUAL STATUS REPORT ON RECYCLED WATER USE Fiscal Year 201 2- 13 Sanitation Districts of Los Angeles County 1 955 Workman Mill Road Whittier, CA 90601 Printed on Recycled Paper DOC NO. 20548303 -ii- PREFACE In addition to its mission of collecting, treating and disposing of municipal wastewater, the Sanitation Districts of Los Angeles County (Sanitation Districts) have adopted the goal of maximizing the beneficial reuse of the highly treated effluents produced by its water reclamation plants. The Sanitation Districts work with a number of local, regional, and state agencies and other entities in an effort to continue developing recycled water as a “local” water supply to supplement the area’s limited groundwater and imported water supplies. In response to many requests for information regarding various aspects of the Sanitation Districts’ water reuse program, this fiscal year report has been prepared for distribution to interested parties. This report is the twenty-fourth of its kind and includes: historic recycled water use activities, descriptions of plant operations, diagrams of the various recycled water distribution systems, lists of the users and the quantities they used, tables of recycled water quality and plans for expanding the use of recycled water, among other subjects. This report is divided into five chapters. Chapter 1 is an overview of the Sanitation Districts’ water reuse program. Chapters 2, 3, and 4 detail the water reuse activities at each of the Sanitation Districts’ ten water reclamation plants, which are grouped in three geographic areas: Los Angeles Basin, Santa Clarita Valley, and Antelope Valley, respectively. Chapter 5 details the various proposed water recycling projects in the Sanitation Districts’ service area that are currently under development or in the planning phase. In order to improve the flow and readability of this report, the narrative descriptions of the more complicated distribution system facilities (Long Beach Water Department, City of Cerritos, City of Lakewood, Central Basin Municipal Water District’s Century and Rio Hondo systems, Walnut Valley Water District, Puente Hills/Rose Hills system, Upper San Gabriel Valley Municipal Water District’s Whittier Narrows Recreation Area Extension, and the Sanitation Districts’ Eastern Agricultural Site in Lancaster) have been moved to their own individual appendices at the end of this report. The same has been done for the chronology of Sanitation Districts’ reuse activities and all of the individual effluent quality tables. A “Facts-at-a-Glance” summary page containing a brief list of data regarding the Sanitation Districts’ water recycling program for the fiscal year appears before Chapter 1.

Cover Photo: In December 2011, the Palmdale WRP completed its conversion to activated sludge and tertiary filtration from its original oxidation pond secondary treatment process. This was followed by the conversion of the Lancaster WRP in July 2012. Recycled water produced at these two plants can now be used for all reuse applications allowable by the State Department of Public Health. All of the Sanitation Districts’ water reclamation plants, with the exception of the very small La Cañada WRP, are now tertiary treatment facilities. -iii- TABLE OF CONTENTS PREFACE .................................................................................................................................................... iii LIST OF FIGURES..................................................................................................................................... vii LIST OF TABLES ..................................................................................................................................... viii LIST OF APPENDICES .............................................................................................................................. ix FY 12-13 FACTS-AT-A-GLANCE .............................................................................................................. x 1.
