Instructor:  Mark Peterson, P.E.

Course Length: 1.5 Hours

Purpose and Background

Sanitary sewer collection systems serve as one of the backbones of any community. These systems collect wastewater from homes and businesses and convey that wastewater to appropriate treatment facilities. This webinar covers the basic design requirements for sanitary sewer systems and provides some insight into proper application of these requirements to provide a design that exceeds the absolute minimum standards. The webinar also discusses the common construction materials and some selection criteria for different materials.

Primary Discussion Topics

  • Energy concepts in sanitary sewers
  • System Layout
  • Materials
  • Installation depth
  • Design velocity and flow depths

Learning Outcomes

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

  • Determine the basis for minimum slopes for sanitary sewer systems and when they should be avoided
  • Identify how the configuration of sanitary sewer systems are typically determined
  • Gain an understanding of what materials are commonly used and when different materials are appropriate
  • Know how velocity and depth of flow impact the design of sanitary sewer systems

Webinar Benefits

  • Learn how minimum slopes were established for gravity sanitary sewers
  • Examine when minimum slopes should be avoided
  • Find out where structures should be installed in a sanitary sewer system
  • Learn what pipe materials are commonly used in sanitary sewers and how to determine which material is most appropriate for a specific design
  • Find out when flow depth or velocity can become a design consideration

Assessment of Learning Outcomes

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

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

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