Purpose and Background

This course presents the basics of pumping systems hydraulic design for civil engineers. An emphasis is placed on the application of pumping systems in municipal water, wastewater, and stormwater systems.

Topics covered include: pump and system hydraulics; centrifugal pump selection; manufacturers interpretation of pump head-capacity curves; development of system 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; and some common pump operating problems.

This course will provide you with 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 and pumping stations.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Determine which engineering relationships apply to specific pumping situations
• Explain the impact of pump machine construction on hydraulic performance
• Marry theoretical hydraulics with practical pump station and system design
• Explain the latest approaches in wet well design including the new Hydraulic Institute/ANSI Design Standards
• Share positive experiences with other designers and engineers
• Design and select successful pumping systems
• List major classifications of pumps and how that classification affects hydraulic operating conditions and design issues
• Explain the basics of hydraulics and pressure factors as related to pump system design
• Explain flow regimes and which engineering relationships do and do not apply in each regime
• Calculate actual net positive suction head on a pump
• Calculate all system head losses in a pumping system
• Develop a hydraulic grade line
• Explain pump impellers and how different types are hydraulically applied
• Explain and interpret the manufacturers pump head-capacity curves
• Explain and apply the pump affinity laws

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and/or fill in the blank questions).

Who Should Attend?

Civil engineers and design engineers, consulting engineers and project managers, specification writers, construction and mechanical contractors, plant superintendents and operators, and approval agency plan reviewers.
