For the past century, no tool available to water utilities has played a greater part in the conservation of water than the water meter. It has reduced waste and distributed the cost of operating a water system in the most e
37、quitable manner possible. Although patents were issued earlier, it is thought that the rst meter produced in the United States was made in 1857. It was a positive-displacement type with recipro- cating pistons. This design consisted of two cylinders and pistons with inlet and outlet ports arranged s
38、o that while water in one cylinder was discharging, the other was lling. Water owing through the meter was subject to pulsation and high friction loss. Other types of displacement meters manufactured before the turn of the 20th century were the rotary piston, oscillating piston, and nutating disc. O
39、nly the oscillating and nutating types remain in production today, as they have proved satisfactory for meter- ing domestic water services. I.B. History. Standardization of water meters was a matter of concern for many years before the rst standard was adopted. An AWWA committee appointed in 1913 pr
40、oposed the adoption of standards on overall meter lengths and connections in 1915 and 1916. The standards were not adopted officially but were recorded in the proceedings for 1915 and for 1916. The New England Water Works Association (NEWWA), in separate action, appointed a committee in 1916 that pr
41、oduced drafts of standards in 1917. Action on adoption or publication was delayed on the recommendation of manufacturers. In 1916, the meter manufacturers, which for several years had worked informally on the matter of meter standards, formally organized a meter standards committee on which most of
42、the meter manufacturers were represented. The records indicate that those who were not represented were kept informed of the committees activities and given the opportunity to comment on drafts of proposed standards. * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New Yor

44、EWWA committees met for the rst time as a joint committee to review drafts of a proposed standard that had been prepared by the manufacturers committee. Subcommittees appointed at that meeting prepared a nal draft that was approved by the joint committee and submitted to both asso- ciations for appr
45、oval. AWWA adopted the standard on June 9, 1921, and NEWWA adopted it on Sept. 14, 1921. The standard, the rst for any type of meter, was titled “Standard Specications for Cold-Water Meters, Disc Type.” The rst revision of the standard was approved as tentative by AWWA on Oct. 31, 1941. The effectiv
46、e date of the standard was delayed until Jan. 1, 1943. On Mar. 15, 1943, it was approved by NEWWA. The document was advanced from tentative to standard by AWWA on May 10, 1946. Emergency alternative provisions were imposed by the War Production Board from Dec. 1, 1942, to Jan. 8, 1945. Emergency pro
47、visions were imposed again on Jan. 1, 1952. The next edition of the standard was approved by AWWA as tentative on Jan. 23, 1961, and was later advanced to standard without revision on Feb. 11, 1964, and sub- sequently revised on Jan. 24, 1971, May 8, 1977 , Jan. 28, 1990, June 17 , 1995, June 16, 20
48、02, and Jan. 25, 2009. This edition was approved on Jan. 24, 2015. I.C. 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 certificati
49、on program for direct and indirect drinking water additives. Other members 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 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
