Back by popular demand, the practical part of Siphonic Roof Drainage is coming. The ASPE webinar on September 17, 2008 is Part 2 of the subject of siphonic roof drainage systems. Part 2 is for the engineer, designer, or contractor who actually want to engineer or design a siphonic roof drain age system, not just find out what it is or how it works. This session will detail the design and calculations for the engineering of siphonic roof drainage systems. To engineer or design siphonic roof drainage systems requires a higher level of technical understanding and engineering analysis, somewhat similar to engineered automatic sprinkler systems and related  mechanical systems.  This webinar will cover the underlying hydraulic theory and discuss recommended design steps to arrive at efficiently designed drainage systems. The presenter will go through a step-by-step process for a single drain example and a two drain example to demonstrate the concepts of residual head and system balancing. Due to the complexity of the calculations, a commercially available software package will be used during the seminar. This webinar will provide the experienced plumbing engineer with the information and basic calculation tutorial to understand siphonic roof drainage operation and application.

The Presenter: John Rattenbury, R.G Vanderweil, LLP
John Rattenbury, PE is a professional engineer experienced in siphonic roof drainage system design. He designed a siphonic roof drain system for the 1 million square foot Boston Convention and Exhibition Center, the first ever installed in the United States. John attended Rensselaer Polytechnic Institute, Troy, New York where he earned his Bachelor of Science degree in Aerospace Engineering in 1989. He joined Vanderweil Engineers, Inc. in 1993 as an engineer. He specializes in plumbing, fire protection and process systems. Mr. Rattenbury wrote the standards for the American Society of Plumbing Engineers (ASPE), the American Society of Mechanical Engineers (ASME) and the American Society for Testing and Materials (ASTM). He has actively practiced the design of siphonic systems for many years and is the recipient of the 2006 ASPE Award of Merit for his work in this field.  Mr. Rattenbury is a registered professional engineer in 26 States.
