Implications Of NSF Std. 61 Changes And An Asset Management Based Data Driven Protocol For Potable Water Coatings Selection

Protective coatings are utilized for asset preservation on welded steel potable water tanks. The technology available to the Owner or Specifier is diverse and can be difficult to select the most sustainable solution. Data based service life assessment of the various coating options provides the best avenue for completing life cycle costing estimates for decision making.

The National Sanitation Foundation (NSF) has recently revised the NSF/ANSI/CAN Std. 61 “Drinking Water System Components –Health Effects Standard” resulting in the creation of a new standard, NSF/ANSI/CAN Std. 600 “Health Effects Evaluation and Criteria for Chemicals in Drinking Water”.  This results in changes in potable water asset owners’ options for protective coating systems. As well, in June 2021 AWWA published a new revision of the AWWA D102-21 Coating Steel Water-Storage Tanks. Many owners fail to realize a protective coatings system is itself an asset, and asset management principles should be applied to the selection of a protective coating system.
