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, 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 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 and pumping stations.

• Determine which engineering relationships apply to specific pumping situations
• Know the impact of pump machine construction on hydraulic performance
• Learn how to marry theoretical hydraulics with practical pump station and system design
• Learn the latest approaches in wet well design including the new Hydraulic Institute/ANSI Design Standards
• Learn how to design correctly for viscous sludges without using inaccurate rules of thumb
• Share positive experiences with other designers and engineers

• Learn how to design and specify successful pumping systems
• Know the major classifications of pumps and how that classification affects hydraulic operating conditions and design issues
• Review the basics of hydraulics and pressure factors as related to pump system design
• Understand flow regimes and which engineering relationships do and do not apply in each regime
• Understand and calculate actual net positive suction head on a pump
• Understand and calculate all system head losses in a pumping system
• Develop a hydraulic grade line
• Understand pump impellers and how different types are hydraulically applied
• Understand and interpret the manufacturers pump head-capacity curves
• Understand and apply the pump affinity laws
• Review the comparative features of different types of pump stations
• Review and discuss suggested approaches to specifying pumps
• Review and discuss design review items during shop drawing review
• Learn why traditional hydraulic design methods do not work with non-newtonian fluids and sludges
• Review associated station design elements
• Discuss design blunders and how to avoid future errors

Throughout the seminar, class exercises, group discussion, calculation and interpretation of materials taught will help assess students’ achievement.
