30、GEvii Foreword This foreword is for information only and is not a part of ANSI * /AW WA D110. I. Introduction. I.A. Background. The New England Water Works Association (NEWWA) established a committee in 1958 to prepare a standard specification for the design and construction of prestressed concrete

31、water-storage tanks. The committee submitted a suggested specification to NEWWA in October 1962 as a guide to those in the water industry who wished to consider the use of these tanks. American Concrete Institute (ACI) Committee 344 concluded eight years of com- mittee work with a report titled “Des

32、ign and Construction of Circular Prestressed Concrete Structures,” published in the ACI Journal September 1970. This report referred primarily to wire-wound tanks. I.B. History. In the December 1972 issue of Journal AWWA, the applicability of the ACI report to water containment structures was discus

33、sed in four articles. As a result of these articles and continued discussion on the subject, a standards committee was authorized by the American Water Works Association (AWWA) to develop an AWWA standard for circular, prestressed concrete water tanks. An AWWA standards committee on circular, prestr

34、essed concrete water tanks was appointed and held its first meeting June 19, 1974. During its first two years, the com- mittee studied the various types of prestressed tanks then in service or under construc- tion and determined that most were of the wire-wound type. Therefore, the committee in 1976

35、 was directed to limit its scope to the wire- and strand-wound prestressed tank wall design. The first edition of this standard incorporated the work of ACI Com - mittee 344 and contained additional requirements and recommendations, specifically for potable and process water, and for wastewater cont

36、ainment structures. The new standard, ANSI/AWWA D110-86, Standard for Wire-Wound Circular Prestressed- Concrete Water Tanks, was approved by the AWWA Board of Directors on June 22, 1986, and had an effective date of June 1, 1987. The standard has been in use since approval by the American National S

37、tandards Institute (ANSI) on Mar. 3, 1987. The first revision of this standard was initiated by the AWWA Standards Commit - tee during 1990 according to AWWA Standards Council policy. The revised standard ANSI/AWWA D110-95 was approved on June 22, 1995, by the AWWA Board of * American National Stand

38、ards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.viii Directors. The next edition of the standard, ANSI/AWWA D110-04, was approved by the AWWA Board of Directors on Jan. 18, 2004. This edition, ANSI/AWWA D110-13, was approved by the AWWA Board of Directors on Jan. 20, 2013. I.C.

39、 Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement 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 memb

40、ers of the original consortium included the Water Research Foundation (formerly AwwaRF) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United S

41、tates, 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 those required by the state. To evaluate the health effects of products and drinking water additives from such prod

42、ucts, 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. Specific policies of the state or local agency. 3. Two standards developed under the direction of NSF, NSF /ANSI 60,

43、Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certificatio

44、n 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 organizations within their jurisdiction. Accreditation of certi- fication organizations may vary from jurisdiction to jurisd

45、iction. 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 * Persons outside the United States should contact the appropriate authority having jurisdiction.

Both publications available from National Academy of Sciences, 500 Fifth Street, NW, Washington, DC 20418.ix regulated by a USEPA final maximum contaminant level (MCL). The MALs of

47、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. ANSI/AWWA D110 does not address additives requirements.

48、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. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drin

49、king water. 3. Determine current information on product certification. II. Special Issues. II.A. Intent. This standard reflects a committee consensus of industry practice concerning the design, detailing, and construction of circular, prestressed concrete water tanks of several types, with or without vertical prestressing of the tank core wall. The horizontal prestressed reinforcement of the tank wall is accomplished by the application of helically wound high-tensile-stress wire or strand under controlled tension on the surface of the core wall, protected by shotcrete cover
