Sixth Emerging Water Technology Symposium 
IAPMO > Sixth Emerging Water Technology Symposium

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.

Previously called the International Emerging Technology Symposium, the EWTS has been renamed to better associate the event with water- and plumbing-related issues. The sixth EWTS is co-convened by the four associations that have worked together closely over the past few years to grow the symposium and made it a can’t-miss event for those who work or are interested in the fields of safe plumbing, water distribution, and water efficiency. The co-conveners stress that the EWTS is still an international event and welcome abstracts and participation from across the globe.

By clicking on the titles of presentations from the 2018 EWTS program you can see the individual presentation slides. 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. (Download Symposium Program)

Featured topics:

Our Keynote speaker was 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.

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.

Eli Goldstein, CEO at SkyCool Systems, Inc. discussed the new non-evaporative passive cooling technology that can be harnessed to radiate heat to the sky, and can even cool to sub-ambient temperatures under direct sunlight and how the system works to save water.

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.

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.

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.

What is it?

There is no other occasion where participants can meet – all at once and in one place – so many well-known experts in the fields of water and energy efficiency. Attendees learned about emerging products and installation practices and witness the exchange of views on new trends in the industry. Participants heard ideas and approaches about emerging technologies coming to market; learn about innovative green plumbing and mechanical concepts; view presentations and energetic panel discussions; and engage in timely discussions on how the water utility, manufacturing, engineering and trade industries have found solutions through emerging technologies in the water-efficiency, plumbing and mechanical industries.
