3、 AWWA Management Standard This document is an American Water Works Association (AWWA) management standard. It is not a specification. AWWA manage- ment standards describe consensus requirements for utility management practices The use of AWWA management standards is entirely voluntary. This standard
4、 does not supersede or take precedence over or displace any applicable law, regulation, or codes of any governmental authority. AWWA management standards are intended to represent a consensus of the water industry of requirements and practices that utilities should strive to achieve. When AWWA revis
5、es or withdraws this standard, an official notice of action will be placed in the Official Notice section of Journal AWWA. The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official notice. American National Standard An American Nationa
6、l Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, w
7、hether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. Ameri- can National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Producers o
8、f goods made in conformity with an American National Standard are encouraged to state on their own responsibility in advertising and promotional materials or on tags or labels that the goods are produced in conformity with particular American National Standards. Caution n oti Ce : The American Natio
9、nal Standards Institute (ANSI) approval date on the front cover of this standard indicates completion of the ANSI approval process. This American National Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no
10、later than five years from the date of publication.

Pizzi, Environmental Engineering owners; and government regulators. The standards developed under the program are generally
15、intended to improve a utilitys overall operations and service. Among these standards is this effort to establish formal management and operations guidelines. These guidelines identify appropriate practices, procedures, and behaviors whose implementation will promote effective and efficient utility o
16、perations and contribute to protection of public health, public safety, and the environment. AWWAs standards process has been used for more than 90 years to produce American National Standards Institute (ANSI)-approved standards for materials and processes for the water and wastewater utility indust
17、ries. These standards are recog- nized worldwide and have been adopted by many utilities and organizations. Likewise, this performance standard is developed using the same, ANSI-recognized, formal pro- cess. Volunteer standards committees establish standard practices in a uniform and appropriate for
18、mat. Formal approval procedures are used to develop recognized stan- dards. Technical workgroups began the standards development process by identifying best practices for distribution system operation and management, water treatment, and source water management. Formal standards committees were then
19、 formed dur- ing the first quarter of 2001 to develop standards for distribution system operation and management, water treatment plant operation and management, and source water management. This standard is the outcome of the water treatment plant operation and management committee. I.B. History. T
20、he first edition of ANSI/AWWA G100, Water Treatment Plant Operation and Management, was approved by the AWWA Board of Directors on Jan. 16, 2005. This standard was approved on June 12, 2011. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agree
21、ment with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. Copyr

The American Water Works
23、 Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states. Local agencies may choose to impose requirements more stringent than
24、those required by the state. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including 1. An advisory program formerly administered by USEPA, Office of Drinking Water, discontinued on Apr. 7, 1990. 2. Sp
25、ecific policies of the state or local agency. 3. Two standards developed under the direction of NSF, NSF /ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, W
26、ater Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizat
27、ions within their jurisdiction. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not regulated by a USEP
28、A final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANS
29、I/AWWA G100 does not address additives requirements. Users of this stan- dard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable standards. * Water Research Foundation, 6666 W. Quincy Avenue, Denver, CO 80235

Major changes made to the standard in this revision include the following: 1. The foreword was updated to be more consistent with existing manag
35、ement standards. 2. Accreditation language was removed from the foreword. 3. References not specifically mentioned in the standard were removed. 4. Definitions of potable water, reclaimed water, and wastewater were added to this standard. 5. Requirements for record keeping now refer to ANSI/AWWA G40
36、0, Utility Management System. 6. Training requirements remain the same but were moved from the Plant Management section to Human Resources. 7. Accreditation language in appendix B was changed to read “The purpose of this appendix is to provide guidance to those considering pursuing accreditation or
37、who have successfully completed a process to achieve accreditation under established programs.” V. Comments.
