The International Association of Plumbing and Mechanical Officials (IAPMO) recently held a technical committee meeting to address public comments on a new water efficiency and sanitation standard.
When published later this year, WE•Stand will be the nation’s only American National Standard devoted entirely to plumbing and water efficiency. The technical committee addressed these issues:
- Improved provisions for indoor water efficiency and landscape irrigation
- Appropriate permitting and cross-connection prevention requirements for alternate water systems
- Revisions to water heating design provisions allowing new fitting types that help to mitigate biofilm growth by providing improved scouring action in potable water pipes
- Inclusion of a revised, statistically based pipe sizing method for residential applications in the appendices that will support the use of a water demand calculator to assist plumbing system designers to more accurately size systems to be consistent with the lower flow rates and consumption values from water efficient plumbing fixtures and appliances
The final technical committee ballot to review public comments on the 2017 WE•Stand will begin on April 17 and conclude on May 15.
