COURSE NO: C08-010
An Introduction to Wastewater Collection and Pumping
Course Highlights

This online engineering PDH course will introduce you to the principles and practices of wastewater collection and pumping.  You will learn about preliminary sewer design issues, the hydraulic design of gravity and pressure sewers, sewer system layout, appurtenances, and structural design of sewer lines. You will be introduced to the fundamentals of pumped system design, pumping stations and equipment.  You will become familiar with sewer piping and pump station components. You will also learn how to approach evaluation and rehabilitation of existing sewer systems.


This 8 PDH online course is intended for civil engineers and other infrastructure design and construction professionals who want to learn about the basic technology, design guidelines and materials and equipment used in design and construction of wastewater collection and pumping systems (sanitary sewer systems) for residential, industrial and commercial developments.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about the approach, requirements, criteria, considerations, and hydraulic calculations used in the design of gravity sewers
  • Learning about alternatives to gravity sewer systems that would require deep and expensive trench excavation, such as jacking, boring, and tunneling
  • Understanding how the operation and maintenance costs of a pumping station with a forcemain, when capitalized, may offset or be less than the construction costs of a deep gravity sewer system
  • Knowing when high groundwater, unstable soil, shallow rock, or extremely adverse topography make gravity sewers, pump or ejector stations unsuitable, low pressure systems using grinder pumps with small diameter pressure sewers may be a solution
  • Learning how to calculate the average hourly wastewater flowrate in order to design a sanitary sewer system
  • Learning how to calculate extreme peak wastewater flowrates and how to size a sanitary sewer system to accommodate them
  • Learning how to design for unintended inflow and infiltration in wastewater collection systems
  • Learning about the Manning Formula and how to use it in sewer system design
  • Understanding the importance of flow velocity in sewer pipes and velocity guidelines for various flow conditions that may be encountered
  • Knowing the basic parameters for sewer pumping station layout
  • Familiarizing with the different types of sewage pumps and ejectors and when they are used
