FOREWORD

These guidelines were developed as a joint effort between the American Society of Civil Engineers (ASCE) and the American Water Works Association (AWWA) with technical input from the Water Environment Federation (WEF), in accordance with ASCE Rules for Standards Committees, and were published initially as a proposed draft, Guidelines for the Physical Security of Water Utilities (ASCE/AWWA/WEF 2006). That consensus process included balloting by a balanced Standards Committee and reviewing during a public comment period. The provisions of this document have been written in permissive language and, as such, offer to the user a series of options or instructions but do not prescribe a specific course of action. Significant judgment is left to the user of these documents.

These guidelines use customary units with the International System of Units (SI) in parentheses. This approach was in the best interest of ASCE, AWWA, and WEF at the time of development of the initial Draft of these guidelines.
