INSTRUCTOR: Mark Peterson

Purpose and Background

​​This course is the fourth of a four-part series on wastewater system analysis and design. This course will cover design of wastewater pump stations including pump curves, differences between standard water pumps and wastewater pumps, hydraulics in lift stations, wet well sizing, pipe sizing and valve requirements.

Benefits and Learning Outcomes

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

• Explain the basics of pump curves and system curves and how to determine appropriate curves to use.
• Recognize how wastewater pumps are different from standard water pumps.
• Recognize hydraulics in a lift station including the necessary valves.
• Size a wet well and what pump controls are commonly used.

Assessment of Learning Outcomes

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

Who Should Attend?

This course covers a detailed analysis of design of a wastewater lift station, including components and hydraulic calculations. The target audience includes engineers involved in the design of wastewater systems and engineers involved in review of designs of these systems.

Outline

• Pump Curve Basics
• Differences between standard water pumps and standard wastewater pumps (impellers and lower efficiencies)
• Grinder pumps
• Hydraulics in lift stations, including head losses
• Pipe sizing inside a lift station, including minimum and maximum velocities
• Required valves in lift stations and types of valves
• Wet well sizing
• Pump controls (VFD, level controls, alternating pumps)

How to Earn your CEUs/PDHs

This course is worth .2 CEUs / 2 PDHs. To receive your certificate of completion, you will need to complete a short post-test and receive a passing score of 70% or higher within 30 days of the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
