This standard describes the reduced-pressure principle backflow prevention assembly for potable water applications. The assembly shall be capable of withstanding a working water pressure of at least 150 psi (1,034 kPa) without damage to working parts or impairment of function and for operation on hot- or cold-water lines.

This standard describes copper sulfate for use in the treatment of potable water, wastewater, or reclaimed water.

Accessibility

This standard describes hydraulic and pneumatic cylinder and vane-type actuators for operation of valve and slide gates in utility systems.

Accessibility

This standard describes electric motor actuators that are externally mounted on gate, ball, plug, cone, globe, and butterfly valves and on slide gates suitable for use in water, wastewater, and reclaimed water facilities.

This standard describes resilient-seated cast-iron eccentric plug valves, 3 in. (75mm) through 72 in. (1,800 mm) in diameter, with flanged, grooved, or mechanical-joint ends.

Accessibility

This standard describes the design, construction, inspection, and testing of composite elevated tanks that use a welded steel tank for watertight containment and a single pedestal concrete support structure. Requirements for the steel tank, concrete support structure, foundation, and accessories are included.

This standard describes the manufacture of circumferentially prestressed concrete pressure pipe with a steel cylinder and wire reinforcement in diameter sizes 16 in. (410 mm) through 144 in. (3,660 mm) manufactured with a steel cylinder and wire reinforcement. Larger sizes have been manufactured based on the concepts presented in this standard. The standard describes two types of prestressed pipe: (1) lined-cylinder pipe with a core composed of a steel cylinder lined with concrete and subsequently wire-wrapped and coated with premixed cement mortar, and (2) embedded-cylinder pipe with a core composed of a steel cylinder encased in concrete and subsequently wire wrapped and coated with premixed cement mortar. The structural design of prestressed concrete pipe for internal pressure and external load is not presented in this standard but is the subject of ANSI/AWWA C304, Design of Prestressed Concrete Cylinder Pipe. ANSI/AWWA C301 also does not include requirements for handling, delivering, laying, field testing, or disinfecting disinfection of pipe. See AWWA Manual M9, Concrete Pressure Pipe, for this information, as well as certain supplementary design considerations related to thrust restraint, subaqueous installations, and installation in corrosive environments.

This standard describes the critical requirements for the effective operation and management of a reclaimed water program. Reclaimed water, for the purposes of this standard, is treated domestic wastewater that is at all times adequately and reliably treated to the level appropriate for the end use. This is the first edition; as such, there are no major revisions.

This standard defines the methods to be used in the structural design of buried prestressed concrete cylinder pipe (PCCP) under internal pressure. These methods are provided for the design of pipe subjected to the effects of working, transient, and field-test load and internal pressure combinations. The design procedures of this standard are applicable to lined-cylinder pipe (LCP) having inside diameters of 16 in. through 60 in. (410 mm through 1,520 mm) and to embedded-cylinder pipe (ECP) having inside diameters of 24 in. (610 mm) and larger. The design for longitudinal hydrostatic thrust restraint of prestressed concrete cylinder pipe is not addressed in this standard. See AWWA Manual M9, Concrete Pressure Pipe, for information on this topic.
