This standard describes coating systems for coating and recoating the inside and outside surfaces of steel tanks used for potable water storage in water supply service. Coating systems for new bolted steel tanks are not described in this standard (see ANSI/AWWA D103)....
Background. A composite elevated water tank is composed of a welded steel tank for watertight containment, a single pedestal concrete support structure, a foundation, and accessories. The AWWA Standards Committee on Composite Elevated Tanks was formed to prepare a...
This standard establishes minimum criteria for the design, fabrication, and erection of structurally supported aluminum dome roofs. Aluminum dome roofs can be used on any size tank erected in accordance with AWWA standards. When this standard is specified, in the case of conflict...
MANUAL PURPOSE, ORGANIZATION, AND USE This manual is intended to provide guidance to water quality specialists and engineers with theoretical and practical understanding and concepts for using aeration systems to meet current and potentially future regulatory requirements. To assist the reader,...
This standard describes reduced-wall, resilient-seated gate valves with non-rising stems (NRS) and outside screw-and-yoke (OS&Y) rising stems, including tapping gate valves, for water supply service having a temperature range of 33° to 125°F (0.6° to 52°C). Velocity. These valves are intended for...
This standard describes the materials and application of prefabricated polyolefin tape coating systems in coating plants at fixed sites using coating techniques and equipment as recommended by the tape coating manufacturer. For normal construction considerations, tape coatings are applied as a...
This standard describes online chlorine analyzer operation and maintenance (O&M) when the online chlorine analyzer is used for monitoring in the treatment of potable water, reclaimed water, or wastewater. Purpose Continuous chlorine residual monitoring is used for two primary purposes: process...
This standard describes polyethylene (PE) pressure pipe and tubing made from material having standard PE code designation PE4710* and intended for use in potable water, reclaimed water, and wastewater service. PE pipe ranges in nominal size from 3/4 in. (19 mm)† through 3 in. (76 mm) and conforms...
This standard provides the minimum requirements for coal-tar protective coatings and linings used in the water supply industry for buried steel water pipelines. AWWA steel pipe coating and lining standards are written for and based on the service temperature of potable water. For operating...
This standard describes the critical requirements for the effective operation and management of a potable reuse water program, including both direct potable reuse (DPR) and indirect potable reuse (IPR). Purpose The purpose of this standard is to define the critical requirements for the effective...
This standard describes 1-in. (25-mm) through 12-in. (300-mm) air valve and vent inflow preventer assemblies designed for use on the outlet of potable water distribution system air valves furnished in accordance with ANSI/AWWA C512 or storage facility vent pipes. The assemblies shall...
This standard describes the materials and application requirements for factoryapplied, fusion-bonded polyethylene (FBPE) coating to the exterior of steel water pipes and fittings. Maximum temperatures. AWWA steel pipe coating standards are written for and based on the service temperature of...
This standard describes sacrificial anode cathodic protection systems intended to minimize corrosion of interior submerged surfaces of steel water storage tanks. This standard does not describe automatically or manually controlled impressed current systems. Purpose The purpose of this...
This standard describes the fabrication and the testing of nominal 1-in. through 156-in. (25-mm through 4,000-mm) fiberglass pipe and joining systems for use in both aboveground and belowground water systems. Service and distribution piping systems and transmission piping systems are included. Both...
This standard describes the various types and classes of cold-water displacement meters with plastic main cases, in sizes ½ in. (13 mm) through 1 in. (25 mm), for water utility customer service, and the materials and workmanship employed in their fabrication. The displacement meters described,...
This standard describes the various types and classes of cold-water displacement meters with metal alloy main cases, in sizes ½ in. (13 mm) through 2 in. (50 mm), and the materials and workmanship employed in their fabrication. The displacement meters described, known as nutating-disc or...
Introduction As early as 1943, an AWWA technical committee concluded it was necessary to control corrosion of submerged surfaces inside water tanks. At that time, cathodic protection was identified as an effective way to prevent leaks. It wasn't until the 1970s, however, when...
