The intent of this standard is to describe current recommended practice for the design, construction, inspection, and maintenance of wire- and strand-wound, circular, prestressed concrete water-containing structures with the following four types of core walls: Type I - cast-in-place concrete with vertical prestressed reinforcement; Type II - shotcrete with a steel diaphragm; Type III - precast concrete with a steel diaphragm; and Type IV - cast-in-place concrete with a steel diaphragm. This edition of the standard has been edited throughout and includes revisions to stated definitions and terms to achieve a higher degree of consistency among the various AWWA standards. The technical revisions to this standard reflect current thinking and construction practices. They are too numerous to include here and can be found in the Foreward section of the standard.

The purpose of this standard is to provide purchasers, manufacturers, and suppliers with the minimum requirements for thermosetting FRP tanks, including material and design. This standard can be referenced in specifications for purchasing and receiving thermosetting FRP tanks. This standard can be used for manufacturing this type of tank. The stipulations of this standard apply when this document has been referenced, and then only to FRP tanks.

This standard describes the design, fabrication, installation, inspection, and testing of bolted aboveground thermosetting fiberglass-reinforced plastic (FRP) panel-type tanks for potable water storage. Requirements for the fabrication, handling, construction, and testing of FRP panels, concrete and steel foundation structure, foundation, and accessories are included. Site elevation and procurement, tank sizing; post-commissioning inspection and maintenance; and the design, operation, and control of the water distribution system that connects to the bolted aboveground FRP panel-type tank are beyond the scope of this standard. This is the first edition of the standard and there are no major revisions.

This standard pertains to geomembrane materials supplied in sheet form for lining, covering, or lining and covering potable water reservoirs. The successful application of this standard is dependent on an appropriate site evaluation, design, material selection, construction, as well as operations and maintenance. This standard includes requirements for material properties, fabrication, and installation. AWWA Manual M25 complements this standard by providing supplemental definitions of terms, as well as design, installation, operation, and maintenance considerations for geomembrane systems. Major revisions made to this edition of the standard include: standard title was updated; Section 3, Definitions, was updated; Sec. 4.5.5, Repairs, was updated; and, Table 2, Quality-control testing, was updated.

This standard describes minimum requirements for submersible vertical turbine pumps utilizing a discharge column pipe assembly, 5 hp or larger, used in water service, including materials, design, manufacture, inspection, and testing.
