Introduction.

Background.

In 1994, AWWA's Standards Council approved development of a new standard for Horizontal Centrifugal Pumps. The new standard was assigned to AWWA Standards Committee 276 for Horizontal Centrifugal Pumps. Upon review of pump standards development in 1996, AWWA's Standards Council modified the development process to include two new pump standards to replace ANSI/AWWA E101-88, Standard for Vertical Turbine Pumps-Line Shaft and Submersible Types. As part of this action, two committees were renamed. AWWA Standards Committee 276 for Horizontal Centrifugal Pumps was changed to AWWA Standards Committee 276 for Horizontal and Vertical Line Shaft Pumps. Committee 276 was charged with development of ANSI/AWWA E103, Standard for Horizontal and Vertical Line Shaft Pumps. AWWA Standards Committee 375 for Vertical Turbine Pumps was changed to AWWA Standards Committee 375 for Submersible Vertical Turbine Pumps. Committee 375 was charged with development of ANSI/AWWA E102, Standard for Submersible Vertical Turbine Pumps. During development of these two replacement standards, ANSI/AWWA E101-88 was withdrawn effective June 2000. This first edition of E103 was approved by the AWWA Board of Directors on June 24, 2007.
