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...
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 for disinfection of water-storage facilities describes materials, facility preparation, application of disinfectant to interior surfaces of facilities, and sampling and testing for the presence of coliform bacteria, chlorine residual, and acceptable aesthetic...
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...
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...
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...
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...
The purpose of this standard is to provide minimum requirements for the design, construction, inspection, and testing of new cylindrical, factory-coated, bolted carbon steel tanks for the storage of water. This standard is only applicable to tanks with a base elevation...
The purpose of this standard is to provide minimum requirements for the design, construction, inspection, and testing of new welded carbon steel tanks for the storage of water at atmospheric pressure. Tank roofs. All tanks storing potable water shall have...
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...
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...
This standard describes the composition, performance requirements, construction practices and workmanship, design, and methods of testing thermosetting fiberglass-reinforce
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...
