The American Water Works Association first published consensus documents in 1908. Today, there are more than 190 AWWA Standards. From source to storage, from treatment to distribution, AWWA Standards cover all areas of water treatment and supply.

2024年11月27日 · AWWA Standards are consensus documents created by volunteer committees and accredited by ANSI. They offer minimum requirement guidelines on all facets of water. As technologies evolve, AWWA Standards are a trusted resource that reflect the state of the industry.

*For Residual Pressures at Fixture Outlet from 60-80 psi, Pressure Adjustment Factor is 1.00 per Table 4-3 Add Irrigation – Sections* x 1.16 or 0.40† = gpm – Hose Bibs x Fixture Value x Press. Adj. Factor = gpm Added Fixed Load = gpm

To determine fireline meter size, the Safe Maximum Operating Capacity in GPM must be greater than the combined sum of the domestic demand and the minimum required fire flow. For example, a domestic demand of 368 gpm plus the minimum required fire flow of 1875 gpm equals a combined domestic and fire demand of 2243 gpm.

AWWA Manual M22 The American Water Works Association published the first edition of M22, Sizing Water Service Lines and Meters, in 1975. The manual was the first effort to provide guid-ance to the water industry on sizing water meters and services to meet the objectives of water utilities and their customers. The AWWA Distribution and Plant ...

This standard describes 3- to 48-in. (76- to 1,219-mm) gray-iron or ductile-iron fittings to be used with ductile-iron pipe for water, wastewater, and reclaimed water. Requirements for fittings with mechanical joints and flanged joints are listed in Tables 3 through 21 at the end of this standard.

2024年4月1日 · 内容提示： ANSI/AWWA C207-18 (Revision of ANSI/AWWA C207-13)AWWA Standard®SMSteel Pipe Flanges for Waterworks Service, Sizes 4 In.

Table 14 lists working pressures and maximum depths of cover for standard laying conditions and standard pressure classes. Table 15 lists special thickness classes of ductile-iron pipe. This standard can be referenced in purchase documents for the thickness design of ductile-iron pipe.

2019年7月18日 · AWWA publishes over 170 standards and 52 manuals of practice. These publications are instrumental in planning, designing, specifying, construction, commissioning, and operating water facilities worldwide. Knowing how to utilize these documents is essential to owners and engineers being able to fulfill their obligation as water professionals.

note: although awwa does not recommend a continuous flow of greater than 50 percent for displacement and multijet meters, meter equivalents are calculated on a proportional basis and remain the same regardless of allowable rates.
