Frank P. Sidari III, PE BCEE
V.P. SPL Consulting Services
Special Pathogens Laboratory


The field of engineering can take you on many different paths.  During this seminar Mr. Sidari will share some of his engineering experiences while providing a detailed review of Legionella and his work in this field.  Legionella is a waterborne pathogen prevalent in building water systems and is the cause of a potentially deadly pneumonia known as Legionnaires’ disease.  This seminar will provide an introduction to Legionella and Legionnaires’ disease, review of transmission risks, and discussion of engineering controls.  Mr. Sidari will also share some of his learnings on what goes into a successful engineering work product and lessons he has learned, which can be applied across engineering disciplines. 

Learning Objectives

Upon completion, participant will:
  1. Have an understanding of Legionella, Legionnaires’ disease, and controls
  2. Be able to describe the steps in the chain of infection
  3. Take away concepts to improve future engineering designs


Frank P. Sidari III, PE, BCEE, is vice president of SPL Consulting Services. A registered professional engineer, board certified environmental engineer and certified construction document technologist, Sidari has significant experience in all phases of water/wastewater engineering projects.

During his previous positions at URS Corporation and ARCADIS/Malcolm Pirnie, Sidari developed clients, prepared proposal, conducted studies, developed detailed design and specification, permitting, and provided field and construction services. His project work has focused on collection/distribution systems, pumping, storage, treatment, and disinfection on systems from 10 gallons to 70 million gallons per day.

Throughout his career, Sidari has provided engineering consultation on water systems impacted byLegionella. He began his work in Legionella at Special Pathogens Laboratory in 2000 while in the graduate program in Civil and Environmental Engineering at Carnegie Mellon. During that time, Sidari evaluated the efficacy of chlorine dioxide, and published the first field evaluation of chlorine dioxide disinfection of a hospital campus water system to control Legionella pneumophila in the Journal of the American Water Works Association

In addition to his professional activities, Sidari, who believes that encouraging youth in science, technology, engineering and math is one of the most important things he can do, mentors middle school students at The Ellis School in the Future City competition—a national, project-based learning experience where students in 6th, 7th, and 8th grade imagine, design, and build cities of the future—twice taking them to the national finals in the past five years.

A graduate of Carnegie Mellon, Sidari holds a Master of Science degree in Civil and Environmental Engineering. He received his BS in Forest Engineering from SUNY Environmental Science and Forestry at Syracuse.
