ASPE announced it has partnered with the International Association of Plumbing and Mechanical Officials (IAPMO) to provide three new webinars.
Net Zero Plumbing: Addressing the Water, Energy, Carbon, and Nutrient Crises
April 1 | Instructor: John Lansing, CPD, LEED Green Associate, Plumbing Designer, PAE
As water stress is projected to continue increasing globally in the coming decades, an assessment is necessary on the role buildings play in mitigating this crisis. Recycled water and rainwater harvesting systems are becoming standard in a growing number of cities and are helping to build more resilient plumbing systems, protecting public health and sanitation in the built environment. Cities seeking to decarbonize the building sector are phasing out natural gas in new construction, which currently represents a majority of direct emissions from buildings. Electric heat pump technology has taken the lead as the primary technology for building heating systems and requires a shift in design approach for domestic hot water systems to reduce strain on electrical power grids. Phosphorus and other soil nutrients are being depleted from agricultural soils while flowing abundantly from the sanitary drainage systems in buildings with each water closet flush. How can these four crises be addressed while moving towards more holistic plumbing systems for the 21st century? In this hour, we’ll discuss the impact of water stress, decarbonization, and nutrient deficits and focus on solutions that enable buildings to integrate into the local ecology.
Water Quality 101: Theory and Practice
April 14 | Instructor: Vanessa Speight, PhD, P.E., Professor of Integrated Water Systems
Water distribution systems are complex reactors affected simultaneously by chemical, microbiological, and hydraulic conditions. Understanding how these factors interact is the key to managing water quality, in both water utility distribution systems as well as plumbing systems. This presentation will cover the fundamental reactions taking place as well as recent research into management strategies from the UK, U.S., and beyond.
New Perspectives on Water Quality: Is Water Hammer and Air in Domestic Water Pipe Causing Corrosion?
May 2 | Instructor: Phil Woolhouse, Director, Phil Woolhouse Hydraulics Pty. Ltd.
In the 1990s, Western Australia (WA) used copper in circulated hot water systems, but it was having issues with failure from pitting and corrosion. When polypropylene random copolymer (PPR) entered the WA market, engineers changed their specifications from copper to PPR. Ten years later, PPR encountered some issues, and many engineers went back to specifying copper. Instructor Phil Woolhouse asked why copper would not fail again, and nobody could provide an answer. In 2012, he began studying hot water pipe failure, and discovered issues of which many in the industry were unaware or had forgotten about due to changing technology. Phil discovered that plumbing systems have never been thoroughly measured and that when you measure something, you quickly understand that what is happening is quite often not what you think is happening.
