2024年11月27日 · AWWA 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 the products and processes related to all areas of water treatment and supply. These documents reflect the state of the industry.

AWWA D100-11, Welded Carbon Steel Tanks for Water Storage: This standard applies to design of welded steel reservoirs and standpipes. AWWA D100: a minimum of 2 round or elliptical shell manholes within first ring. Each a minimum of 24 inches in diameter or 18” x 22” elliptical. One shell manhole at least 30 inches in diameter.

• AWWA “Steel Water Storage Tanks” (2010) Chapter 10, Page 381: “Why have a maintenance program? The answer is simple: Preventive maintenance has been, and always will be, less expensive than crisis maintenance.” • DETERMINATION OF MAINTENANCE NEEDS FOR ONE OF THE WATER SYSTEMS MOST VALUABLE ASSETS:

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.

This standard provides 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 substantially at ground level.

A complete engineering reference on steel water storage tanks, including siting, design, fabrication and construction. Covers welded, bolted, ground-supported and elevated tanks.
