This webinar will provide information on the background, operation and design of siphonic roof drainage systems. The webinar will cover the underlying hydraulic theory and discuss recommended design steps to arrive at efficiently designed drainage systems. The course also covers various practical issues such as authority approvals, product specification and existing standards.

Siphonic roof drainage is easily one of the "hottest" new technologies to be introduced into the American plumbing engineering field. Siphonic roof drainage requires a certain level of technical analysis similar to engineered automatic sprinkler systems and other mechanical systems.

This webinar is an introduction to siphonic roof drainage technology for the experienced plumbing engineer to gain understanding of siphonic roof drainage operation and application.

The Presenter: John Rattenbury, R.G Vanderweil, LLP
John Rattenbury, PE is a senior engineer at R.G. Vanderweil Engineers, Inc. of Boston, Mr. Rattenbury designed a siphonic roof drain system for the 1 million square foot, $450 million, Boston Convention and Exhibition Center, the first ever installed in the United States. Mr. Rattenbury 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 specialized in process utility systems including high-purity water systems, USP clean utilities, compressed air systems, process vacuum systems, wastewater systems, water reclamation systems and siphonic roof drainage. He practices in many of these fields today. 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 the States of Connecticut, Massachusetts, New Jersey, New York, Mississippi, and Virginia.
