18、d G100 SECTION 2: FOREWORD is operational guide has been written as a guidance tool for the imple- mentation of water treatment plant operation and management best practices, as set forth in ANSI/AWWA Standard G100, Water T reatment Plant Operation and Management (AWWA G100; 2011b). AWWA G100 is par

19、t of the voluntary man- agement standards for water utilities, initially established in 2004. e original idea for the operational guide series to accompany the utility management standards came from utility managers who participated in a two-year pilot project that was conducted and supported by the

20、 American Water Works Association (AWWA) Utility Quality Programs Committee, the AWWA Accredi- tation Committee, and nearly 30 utility professionals from more than 10 North American utilities. e pilot project assessed the applicability and practicality of the series of AWWA utility management standa

21、rds by working with two utilities Birmingham (Ala.) Water Works and Sewer Board and Washington County (Va.) Service Authorityand a team of volunteers from utilities, consulting rms, and other organizations. During the pilot process, the utility managers requested that AWWA develop some type of guida

22、nce or how-to documents to go along with the management standards. ese guidance documents would serve two purposes: one, help util- ity managers understand the purpose and function of these new standards, and two, help them implement and incorporate the standards into everyday operations. From this

23、suggestion the series of operational guides was conceived. SECTION 3: INTRODUCTION In order to consistently supply high-quality water drinking water to custom- ers, the eective operation and management of drinking water treatment plants is essential. Critical requirements for the eective operation a

24、nd management of drinking water plants are the subject of this guide, which provides suggestions and examples to assist water treatment plants in using AWWA G100. Water Treatment Plant Operation and Management 3 e US Environmental Protection Agencys (USEPAs) Safe Drinking Water Act ensures public sa

25、fety by setting extensive regulatory requirements for public water suppliers. However, progressive utilities may voluntarily subscribe to addi- tional requirements, such as the AWWA utility management standards, in order to take a more proactive approach to guarantee that a high-quality product, whi

26、ch exceeds regulatory requirements, reaches the consumers taps. ANSI/AWWA Standard G100, Water Treatment Plant Operation and Man- agement, is based on water treatment plant operation and management best prac- tices, developed by consensus of the AWWA Standards Committee. AWWA G100 also calls for qua

27、lity operation and maintenance of water treatment plants through the appropriate expertise of those operating and managing the system. is guid- ance document has been established to assist any water treatment plant, large or small, in adopting those practices set forth in AWWA G100. is guide breaks

28、AWWA G100 down into the following components: Standard Languagee Standard Language is each section of A WWA G100, as written in the latest standard document. Rationalee Rationale gives background on the topic in each section of the standard and discusses why the requirements are important for water

29、treatment plants. Examplese Examples given do not cover every aspect of the standard and will not apply to every utilitys situation. ey are not intended to be a com- plete instruction guide for the implementation of AWWA G100, rather they are intended to point interested parties in the right directi

30、on and give insight on how processes and procedures may be properly implemented in accordance with parts of the standard. In order to keep this publication to a reasonable size, only a hand- ful of examples per topic were included, and most point to a secondary publica- tion with current standard op

31、erating procedures and practices used by utilities in a standardized format. ere are also many sources of additional information listed in the References and Resources section. Questions to Check Progresse Questions are listed as a tool to self-assess the status of a utilitys compliance with AWWA G1

32、00. If a utility can conrm that it has all items in the questions in place, management may wish to consider apply- ing for recognition, or the utility may be able to leverage that information when negotiating a bond rating.4 Operational Guide to AWWA Standard G100 e Audit Checklist is included to fu

33、rther assist utilities in performing an initial gap analysis or assessing their progress in implementing AWWA G100. is tool will help identify any gaps that may exist in current procedures and those required to meet the standard. It asks specic questions and looks for proof and documentation that pr

34、ocedures are indeed in place where called for by the stan- dard. Just as the examples are not an instruction manual for implementing all of AWWA G100, 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

35、 AWWA G100 standard well covered in its operating and management procedures and practices. SECTION 4: REQUIREMENTS e minimum requirements for the operation of drinking water treatment plants can be divided into four major categories: regulatory compliance require- ments, operational management pract

36、ices, plantreal property management and maintenance, and water quality management. is standard requires that the utility establish measurable goals for each category, implement a monitoring sys- tem to measure performance against the goals, employ an optimization strategy to identify opportunities f

37、or improvement, and maintain consistent operation that satises the goals under conditions. Goals must be set with the concept of protecting public health foremost in mind, and shall include water quality and quantity targets. Many relationships and linkages exist among the major elements of water tr

38、eatment plant operation and maintenance. e requirements listed in this stan- dard are meant to apply to water treatment plants. However, the system operator is cautioned to consider the eect of one requirement upon another based on site-specic conditions. Water Treatment Plant Operation and Manageme

39、nt 5 Sec. 4.1 Compliance With Regulatory Requirements e plant shall satisfy the requirements of all applicable federal, state or provin- cial, and local regulations that apply to the operation of the plant. Plants shall demonstrate that as a minimum they meet the applicable drinking water regula- ti

40、ons for their own jurisdiction. Rationale Customers expect their utility to meet or exceed all applicable regulations. In fact, maintaining consumer condence demands that the utility maintain com- pliance. Protection of public health requires that water treatment plants produce water that meets all

41、local, state, provincial, federal, or other regulatory require- ments. e list of requirements that apply may be dierent for dierent treatment plants as some requirements are tied to the type of source water or treatment pro- cesses utilized. Responsibility for tasks that maintain compliance with the

42、 regula- tions applying to treatment plants might fall to personnel outside the plant sta, so coordination within the utility is essential to ensure that compliance requirements are met and documented. Plants that are initiating eorts to meet AWWA G100 and require coordination across the utility to

43、meet regulations would prot from parallel application of ANSI/AWWA Standard G400, Utility Management Sys- tem, and its companion Operational Guide to AWWA Standard G400 (Ginley and Humphrey 2009). One approach to managing regulatory requirements is to simply make a list of them, keep it up to date,

44、and identify where the regulation can be found (e.g., a URL on the Internet or a book of codes). To make this list even more use- ful, identify the person(s) or sta position(s) responsible for ensuring compliance.
