Pumping Systems Design for Civil Engineers

Instructor

David Hanna, P.E.
David Hanna is a graduate of Rensselaer Polytechnic Institute with a M.S. degree in environmental engineering, and a B.S. degree in marine engineering/mechanical from the United States Merchant Marine Academy. Mr. Hanna is an Associate Professor at Ferris State University with faculty responsibilities in the construction management and surveying engineering programs.

Mr. Hanna worked for several consulting engineering and construction management firms for eighteen years before joining the faculty at Ferris State University in 1991. Mr. Hanna is a licensed professional engineer in Michigan and Ohio. He has designed numerous pumping stations and pumping systems associated with water and wastewater projects. Sizes of the facilities range from 80 gallons per minute to 30 million gallons per day. His experience includes design, construction administration, construction installation and quality control, and startup of new facilities as well as evaluation and troubleshooting of existing pumping and treatment facilities.

Mr. Hanna has served as an Instructor on hydraulics, pumping systems, and treatment processes to the New York State Department of Environmental Conservation and the New York State Department of Health with operator training and certification programs. He is a technical reviewer of pumping standards for the Hydraulic Institute and a member of ASCE.

Course Description

This seminar presents the basics of pumping systems design and specifications for civil engineers. An emphasis is placed on the application of pumping systems in municipal water and wastewater systems.

Topics covered include:

• Pump and System Hydraulics
• Centrifugal Pump Selection
• Interpretation of Manufacturers Pump Head-Capacity Curves
• Types of Pumping Stations
• Series and Parallel Operation
• Variable Speed Systems
• Friction Losses in Sludge Pumping
• Wet Well Design
• Specifying of Pumps
• Shop Drawing Review Considerations
• Common Pump Operating Problems.

This seminar will provide the hydraulic engineering design needed for successful pump station projects and for providing pumping systems with the necessary hydraulic flexibility required on water and wastewater treatment plants.
