A composite elevated water tank is composed of a welded steel tank for watertight containment, a single pedestal concrete support structure, foundation, and accesso

41、ries. The AWWA Standards Committee on Composite Elevated Tanks was formed to prepare a standard for the design, construction, inspection, and testing of composite elevated tanks. ACI 371R, Guide for the Analysis, Design, and Construction of Elevated Concrete and Composite Steel-Concrete Water Storag

42、e Tanks, and ANSI/AWWA D100, Welded Carbon Steel Tanks for Water Storage, are used as source documents. Work covered by this standard is usually procured under a designbuild contract. It is intended that ANSI/AWWA D107 be used as a reference standard in project docu- ments prepared by purchasers and

43、 engineers specifying composite elevated water tanks. I.B. History. The A WWA Standards Committee on Composite Elevated Tanks was formed in 1992 to prepare a standard for these structures. This is the first edition of ANSI/AWWA D107, and it was approved by the AWWA Board of Directors on Jan. 17, 201

44、0. 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 certification program for direct and indirect drinking water additives. Oth

45、er members of the original consortium included the American Water Works Association Research Foundation (AwwaRF, now Water Research Foundation) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Wa

Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health * Americ
