WE STAND – Water Efficiency and Sanitation Standard for the Built Environment

IAPMO WE Stand 2017 – WE STAND – Water Efficiency and Sanitation Standard for the Built EnvironmentIn November 2017, IAPMO’s Water Efficiency and Sanitation Standard (WE•Stand) was published as an American National Standard, replacing the Green Plumbing and Mechanical Code Supplement. The publication of WE•Stand is noteworthy, as it is the first-ever ANSI standard that focuses solely on achieving safe and efficient water use in both residential and non-residential buildings.

What’s in it? See below for just a few of the significant new provisions contained in the inaugural edition of WE•Stand:

• New Provisions for the Codification and Safe Use of Composting Toilets: WE•Stand contains the first set of comprehensive codified requirements for the installation, safe use and maintenance of composting and urine diversion toilet fixtures applicable to commercial and residential applications.
• New Safety Requirements for Leak Detection Systems: New safety provisions for leak detection systems that take fire suppression systems into account.
• Landscape Irrigation: New efficiency-related provisions for system inspection and performance.
• Swimming Pool Provisions: New requirements pertaining to the energy efficiency of swimming pool pumps per the latest industry standards.
• Indoor Water Efficiency: Contains thoughtful flow rate and consumption requirements for plumbing fixtures and appliances that take both safety and water and energy efficiency into consideration.
• Alternate Water Sources: Progressive provisions for uses of gray water generated from clothes washers in landscape irrigation. New requirements that reduce the cost of retrofitting gray water systems in single family homes. Allows for the installation of rainwater catchment systems up to 5000 gallons for non-potable uses without requiring inspections under certain conditions, reducing costs to owners
