Work to Begin on Addendum to AWWA C651, Disinfection of Water Mains

The AWWA Standards Council is happy to announce that work on an addendum to a standard has been authorized and is now beginning on the development of the following: 
AWWA C651a, Addendum to AWWA C651, Disinfection of Water Mains

This Addendum will describe procedures for disinfecting building potable water plumbing and service lines in new or repaired systems, prior to beneficial occupancy and is not intended to be applied as a remedial disinfection procedure for any building. It will cover minimum recommendations for the preparation and flushing of building potable water systems, application of chemical disinfectants, chemical disinfectant testing, and microbiological validation.

Addendum to AWWA C651 has been assigned to the existing Standards Committee on Disinfection of Facilities. Please contact Amanda Dail (adail@awwa.org) if you would like to participate or if you have any questions about the work on the addendum.
