The purpose of this standard is to provide guidelines for use in preparing purchase documents for the procurement of GAC reactivation services where GAC is used as an adsorptive medium for treatment in potable water, wastewater, and reclaimed water systems.

The purpose of this standard is to provide the minimum requirements for ductile-iron, steel, and alloy high-performance butterfly valves suitable for raw, potable, and reclaim/reuse water service.

The purpose of this standard is to provide the minimum requirements for potable cold-water meters of the electromagnetic and ultrasonic type, in sizes 1/2 in. (13 mm) through 20 in. (500 mm), for revenue applications.

This standard describes essential procedures for the replacement of lead water service lines and flushing following replacement. This standard also describes procedures for partial replacement and repair situations where complete lead service line replacement is not possible or practical.

This standard describes the double check-valve 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 potable water lines.

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 the critical requirements for the effective operation and management of drinking water treatment plants.

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

This standard describes gravel, high-density gravel, silica sand, high-density media, anthracite filter materials, and the placement of the materials in filters for water supply service application. ANSI/AWWA B604, Standard for Granular Activated Carbon, addresses use of GAC as a filter medium and as an adsorbent.

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