Source Water Protection Operational Guide to AWWA Standard G300
|Publication Date:||1 January 2017|
AWWA's primary goal is to support water utilities in the evaluation and improvement of their water quality, operations, maintenance, and infrastructure. Several programs and types of publications are used to support this mission.
A key program is the AWWA Standards Program, which has existed for more than 100 years to produce peer-reviewed standards for the materials and processes used by water and wastewater utility industries. These standards, which are American National Standards Institute (ANSI) approved, are recognized worldwide and have been adopted by many utilities and organizations. The AWWA Standards Program is designed to assist water and wastewater utilities and their service providers
in meeting the expectations of their customers, investors, and government regulators. The standards developed under the program are generally intended to improve a utility's overall operations and service.
Recently, AWWA also developed a series of management standards for water and wastewater utilities. The Utility Management Standards Program provides a means to assess service quality and management efficiency based on recognized standards for best available practices. Through these standards and formal recognition by professional organizations, the program serves water and wastewater utilities by promoting improvements in the quality of services and efficient management.
The utility management standards address the utility manager's need to have consistency and reliability and to know what is expected in the management and operation of a utility. These standards are also valuable resources for the many issues that utilities face, including increased scrutiny on accountability, increased regulation, and difficult economic realities such as aging infrastructure, changing demand for water, and a shrinking workforce.
The utility management standards are designed to cover the principal activities of a typical water and/or wastewater utility and include the following:
• G100, Water Treatment Plant Operation and Management
• G200, Distribution Systems Operation and Management
• G300, Source Water Protection
• G400, Utility Management System
• G410, Business Practices for Operation and Management
• G420, Communications and Customer Relations
• G430, Security Practices for Operation and Management
• G440, Emergency Preparedness Practices
• G480, Water Conservation Program Operation and Management
• G481, Reclaimed Water Program Operation and Management
• G510, Standard for Wastewater Treatment Plant Operations and Management
The utility management standards are developed using the same formal, ANSI-recognized, AWWA-managed process. Volunteers on the standards committees establish standard practices in a uniform and appropriate format. Formal standards committees are formed to address the individual standards of practice for the diverse areas of water and wastewater utility operations.
ANSI/AWWA Standard G300, Source Water Protection, is the definitive standard for a drinking water utility to use to protect its drinking water supply source(s). The first edition of ANSI/AWWA G300 became effective on July 1, 2007, and was revised on June 1, 2014. The standard outlines the six primary components of successful source water protection (SWP) programs and the requirements for meeting the standard.
Given that every water system is unique, SWP elements vary from utility to utility. The standard can be used to guide development of a SWP program by following the framework presented. Also, it can be used to evaluate the completeness and potential effectiveness of an existing SWP program by comparing a program's components with those listed in the standard to ensure all important parts are included.
This guide is intended to provide support and guidance to help utilities plan, develop, and implement successful SWP programs that will meet the criteria listed in ANSI/AWWA G300. However, it is not intended to be a complete instructional guide for implementation of ANSI/AWWA G300 and may not apply to all situations encountered by individual utilities. It also does not have any specific regulatory linkage and does not specifically address source water selection or certain aspects of source water management (e.g., treatment of reservoir water to control algal growth and stratification).
This guide starts with acknowledgments (Sec. 1) of key individuals who assisted in the development of ANSI/AWWA G300 and this associated operational guide. Section 2 (this Foreword) describes the basic tenets of the AWWA Utility Management Standard Program and describes the outline of this guide.
Section 3, Introduction, includes basic information and guidance about SWP programs and activities and a brief description of the six essential elements (or phases) that comprise a successful SWP program. This section explains how this guide can be used to assess whether a SWP program has met the criteria of ANSI/ AWWA Standard G300.
Section 4, Requirements, lists the specific requirements of the SWP standard. There are six subsections, one for each of the six basic elements of a successful SWP program. Each subsection includes a description of the rationale for the specific requirement, a description of the program component and related issues, some suggested approaches, and, for some elements, a list of resources for further information.
Section 5, Verification, includes a description of documentation and human resources needed to verify compliance with the standard.
Section 6, Glossary of Abbreviations, lists the abbreviations used in this guide.
Section 7, Resources, lists relevant national-level stakeholders.
Section 8, Annotated Bibliography for Select Information Sources, provides descriptions and web links for helpful reports, websites, databases, and other sources of information and guidance.
Section 9, References, lists all references cited in this guide.
Section 10, Worksheets, contains many questions in checklist format that utilities can use to self-assess their progress. These questions serve as the basis for reporting progress related to ANSI/AWWA G300, Standard for Source Water Protection. These worksheets are not intended to serve as blueprints to all SWP programs. However, a utility that has all the components represented in the checklists is likely to have the principle elements of the ANSI/AWWA standard incorporated into its SWP program and practices. The worksheets can be used to ensure that important subjects are covered for each component, to find additional ideas that may not have been included in the existing program, and to help identify gaps that may exist in a utility's current procedures compared to the requirements of the standard. The worksheets also serve to solicit proof and documentation that procedures are indeed in place where called for by the standard.
Section 11, Case Studies for Source Water Protection, describes three successful SWP programs for the following utilities: Philadelphia Water (Pa.), Central Arkansas Water (Little Rock), and Remsen Municipal Utilities (Iowa). Each case study follows the framework of the ANSI/AWWA Standard and thus provides examples of different ways to accomplish each necessary component. They also show innovative elements that go beyond the minimum requirements of the standard. Philadelphia Water and Remsen Municipal Utilities are past recipients of the AWWA Exemplary Source Water Protection Award, which is based on following the concepts laid out in the standard.
