INSTRUCTOR: Mark Peterson
Purpose and Background
??This course is the third of a four-part series on wastewater system analysis and design. This course will cover design of sewer force mains including pipe materials, friction factors, minimum and maximum velocities, thrust restraints, water hammer and air/vacuum requirements.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Recognize how to select an appropriate pipe material for a force main.
- Create the hydraulic calculations involved in the design of a force main and how to select an appropriate friction factor.
- Explain the importance of thrust restraint on a force main and how water hammer impacts the required thrust restraint.
- Recognize where to place air/vacuum valves in a force main system.
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 force main, including pipe selection, pressure requirements 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
- Appropriate Pipe Materials (challenges with ductile iron)
- Friction Factors
- Hydraulic Calculations, including minimum and maximum velocities
- Thrust restraint – thrust blocks vs. restrained joints
- Water hammer/hydraulic transients
- Air/vacuum valve requirements and challenges
- Discharges from force mains
How to Earn your CEUs/PDHs
This course is worth .3 CEUs / 3 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]
