INTRODUCTION

Just as important as the quality of the water supplying the distribution system is the quality of O&M used to maintain that system. If the infrastructure used to transport water to customers is allowed to deteriorate and operate without any level of standards, the quality of the water delivered cannot be guaranteed safe for consumption, let alone of high quality.

The US Environmental Protection Agency's (USEPA's) Safe Drinking Water Act ensures public safety by setting extensive regulatory requirements for public water suppliers. However, progressive utilities may voluntarily subscribe to additional requirements, such as the AWWA G-series of standards, in order to take a more proactive approach to guarantee that a high-quality product, which exceeds regulatory requirements, reaches the consumers' taps.

ANSI/AWWA G200, Distribution Systems Operation and Management, is based on water distribution system O&M best practices, developed by consensus of the AWWA Standards Committee. AWWA G200 also calls for quality O&M of distribution systems through the appropriate expertise of those operating and managing the system. This guidebook has been established to assist any water distribution utility, large or small, in adopting those practices set forth in AWWA G200.

This guidebook breaks AWWA G200 down into the following components:

Standard Language-The Standard Language is wording from a section of AWWA G200, as written in the latest standard document. In this guidebook, the standard language is shaded in gray.

Rationale-The Rationale provides background on the topic in each section of the standard and relevance to why the requirements are important for water distribution utilities.

Example of Methods or Procedures-The Examples given do not cover every aspect of the standard and will not apply to every utility's situation. Additionally, they are not intended to be a complete instruction guide for the implementation of AWWA G200, rather they are intended to point interested parties in the right direction and give insight on how processes and procedures may be properly implemented in accordance with parts of the standard. In order to maintain this publication at a reasonable size, only a handful of examples per topic are included. There are also many sources of additional information listed in the References and Resources section (Sec. 6).

Questions to Check Progress-The Questions are listed as a tool to self-assess the status of the utility's compliance with AWWA G200. If the utility can confirm that they have all items in the questions in place, they may wish to consider applying for recognition.

The Audit Checklist in Sec. 7 is included to further assist utilities in performing an initial gap analysis or assessing their progress in implementing AWWA G200. This tool will help identify any gaps that may exist in their current procedures and those required to meet the standard. It asks specific questions and looks for proof and documentation that procedures are indeed in place where called for by the standard. Just as the examples are not an instruction manual for implementing all of AWWA G200, neither is the checklist a blueprint. However, a utility that has all the components represented in the checklist is likely to have a majority of the G200 standard well covered in their operating and management procedures and practices.
