This one-hour webinar will provide an overview of the development and implementation of vacuum plumbing systems. The participant will learn how to apply this engineered technology as well as address apparent code related discrepancies and how to gain AHJ approval. The presentation will address the design processes required for successful implementation of vacuum in sanitary plumbing systems. Topics covered include:

  1. Overview of Vacuum System Operation
    • Benefits of vacuum plumbing systems
    • Similarities to conventional sanitary systems
    • Code requirements and approval
  2. Vacuum System Applications
    • Definition of Engineered Systems
    • Current uses and limitationsl
  3. Construction Document Preparation
    • Calculations and applicability of Hunters Curve
    • Development of waste load profiles
    • Drawing preparation
    • Construction challenges 


About the Speaker: Mark Thayer

Mark Thayer, is a senior plumbing systems designer with AECOM, a global professional services firm providing integrated design, planning, engineering, environment and program management services. Mark has an Associate of Science degree from Schoolcraft College in Livonia Michigan (1978) and a Bachelor of Science degree from Liberty University in Lynchburg, Virginia (1987). He is a charter member of the Virginia Blue Ridge Chapter of ASPE and has served as Vice President Legislative, Vice President Technical and Chapter President. His plumbing design project portfolio includes government buildings, military installations, correctional institutions, museums, nuclear test and research laboratories, healthcare facilities, retail centers, municipal buildings, parking structures, educational facilities, commercial buildings, and multi-family residential complexes.


Mark is an industry leader in engineered alternative vacuum waste plumbing systems.  In 2004, he developed the schematic design for a vacuum plumbing system in the Smithsonian Institution’s National Mueseum of Natral History in Washington, DC. In 2005, he developed the design concept and engineering for the first jail-based vacuum plumbing system on the East Coast for the Western Virginia Regional Jail, one of the first LEED Certified jails in the United States. Mark participated in the 2006 ASPE Convention in Tampa, Florida, as co-presenter on the subject of vacuum sewer and waste systems. Mark has authored two industry articles on vacuum plumbing, including PM Engineer Magazine’s “The Next Frontier, Vacuum Plumbing Systems,” the magazine’s cover story for the February 2008 issue. He also wrote the March 2010 green feature in ASPE’s Plumbing Systems & Design, “Escaping the Shackles of Tradition,” which won a green feature writing award at the 2011 APEX Awards for Publication Excellence. Most recently, Mark accepted a nomination by the ASPE Design Standards Committee to serve as Work Group Chairman for the development of a Design Standard on Vacuum Plumbing Systems. As leader of this effort, he has assembled a team of eight engineers and technicians to write the standard, which is expected to be presented for public review in 2012.
