Save the Date for the Virtual “Updating the Hunter’s Curve Summit”

Updating the Hunter's Curve SummitASPE and the International Association of Plumbing and Mechanical Officials (IAPMO) are co-hosting “The Water Demand Calculator: Updating the Hunter’s Curve Summit,” a virtual event on November 4, 2021, from 9 a.m. to 5 p.m. CST.

This virtual event will review the history of Hunter’s curve and discuss what the future holds for the Water Demand Calculator. It will specifically focus on adapting the WDC to commercial needs and explore the challenges it needs to overcome. Come join us as we explore the future of plumbing and make history together. Details and registration will be provided soon.

During this event, the following topics will be covered:

  • “History of Hunter’s Curve,” Dan Cole, Sr. Director of Technical Services at IAPMO
  • “Water Demand Calculator Development,” Steven Buchberger, Professor of Civil and Environmental Engineering at the University of Cincinnati
  • “The Future of the Water Demand Calculator,” Tim Wolfe, TRC Worldwide Engineering MEP LLC
  • “Data Analytics, Machine Learning, and Engineer Research Initiatives,” Dustin Schafer, Chief Technical Officer at Henderson Engineers
  • “Manufacturers and Data Collection,” Tory Schira, COO of LiquiTech
  • “International Perspective: German Domestic Water Sizing Methodology,” Frank Schmidt, International Market Developer at Gebr. Kemper GmbH + Co. KG
  • “European Perspectives on Water Distribution,” Vanessa Speight, Professor of Integrated Water Systems at the University of Sheffield

The WDC represents the first major update to plumbing sizing requirements since the 1940s and provides a new alternative to Hunter’s curve when estimating water supply demand for residential buildings. The WDC predicts peak water demand for single- and multifamily dwellings when water-efficient fixtures are installed. It works in conjunction with any commonly accepted rules and procedures for sizing the water supply system, which results in improved scouring action in water pipes, shorter water dwell times in premise plumbing systems, improved water quality, faster hot water delivery times throughout the plumbing system, reduced energy use, and reduced construction costs.
