6th Emerging Water Technology Symposium


May 15-16, 2018

The American Society of Plumbing Engineers (ASPE), the Alliance for Water Efficiency (AWE), the International Association of Plumbing and Mechanical Officials (IAPMO), and Plumbing Manufacturers International (PMI), in cooperation with the World Plumbing Council (WPC), convened the sixth biennial Emerging Water Technology Symposium (EWTS) on May 15-16, 2018.

This biennial event continued to provide critical insight into the future of our water related industries. Nowhere else is such focused attention provided for professionals on all facets of optimizing the safe and efficient use of water.

In fact, the sixth EWTS had more of an international flair than ever and the WPC co-located its 2018 Executive Board and General Membership meetings with the EWTS! This will be the best symposium yet.




John McNally, John Mesenbrink, Sharon Rehana and Steven Spaulding

Keynote Speaker:

Dr. Peter Williams, Independent Consultant and Advisor - Formerly Smart Cities and Resilience Lead for IBM’s Utilities Practice
Information Technology Trends and the Water Industry

Dr. Peter Williams who has played a major role in the development and delivery of IBM’s smart cities, water management and resilience solutions. He has worked with organizations as diverse as the UN and EU; many city, state and local governments; and many utilities on these issues. He co-wrote the UN’s City Disaster Resilience Scorecard, used by about 40 cities globally, and now scheduled to be used by a further 200. His key note will focus on how IT solutions, smart sensors and big data are changing what we know about consumer water use.

Peter Mayer, Principal, Water DM 
Water Demand Trends, Efficiency and the Future of Urban Water Use

Bill Hoffman, President, H.W. Hoffman and Associates: Institutional, Commercial and Industrial (ICI)
Water Use by the Numbers

Paula Kehoe, Director of Water Resources, San Francisco Public Utilities Commission
Advancing Non-Potable Water Systems
Paula Kehoe of San Francisco Public Utilities Commission updated attendees on their efforts to advance the use of non-potable water systems. The non-potable water program is an interagency collaboration with the Department of Public Health (SFDPH), Department of Building Inspection (SFDBI), and San Francisco Public Works. It has helped to establish a regulatory framework and water quality monitoring and reporting requirements for the collection and use of alternate water supplies such as rainwater, graywater, stormwater, foundation drainage, and blackwater for non-potable applications such as toilet flushing and irrigation.

Rainwater Harvesting in the 21st Century

Steven Buchberger, PhD, PE, Professor and Head Department of Civil & Architectural Engineering & Construction Management, College of Engineering and Applied Science, University of Cincinnati
Estimating Peak Water Demands in Buildings with Efficient Fixtures - Progress and Prognosis
Professor Steven Buchberger from the University of Cincinnati discussed the first statistically based update to Hunter’s Curve sine the 1940’s. This new approach to pipe sizing, which takes today’s more efficient plumbing fixtures and appliances into account, will improve the water and energy efficiency of every building that is designed using the new method. It will also reduce water residency time in premise plumbing systems, which will help to improve water quality and mitigate breakouts from opportunistic pathogens in water, all without increasing construction costs! Learn how a simple Excel based calculator will allow designers of plumbing systems to easily apply this critically important new quickly and easily.

Smart Cities and Water Re-use
Dr. Markus Lenger, Principal at Clean Blu, Inc. returned to the EWTS to discuss the role of water reuse in smart cities. We all agree that new infrastructure is needed, but what kind? Which existing systems can be reused or re-purposed and what sensors a realistic and power efficient way of collecting data needed? Dr. Lenger walked us through the trends, technologies, concepts and implementations around the world, their relationship to water reuse and how they change lives, improve efficiency and bring sustainability to a whole new level.
