2027 WE•STAND CODE DEVELOPMENT TIMELINE

The 2027 WE•Stand Code Development Timeline is now available for download.

What is the 2023 WE●Stand and what does it address?

The purpose of this standard is to provide minimum requirements to optimize water use practices attributed to the built environment while maintaining the protection of public health, safety, and welfare. The need for the WE•Stand is in recognition that with increasing demand, constrained infrastructure and supplies, climate change, and pervasive droughts globally, there is a critical need to reduce water consumption attributed to the built environment through conservation and reuse. With this comes increased risks to public health, safety, and building systems performance.

Key provisions of the 2023 WE•Stand include:

  • Maximum flow rates for fixture fittings
  • Listings for water treatment systems
  • Water meter performance specifications
  • Landscape design and installation
  • Peak Water Demand Calculator
  • Ecological-sanitation systems
  • Onsite gray water treatment systems
  • Onsite wastewater treatment systems for direct potable water use
  • Gray water-ready buildings
  • Water efficiency ratings
