An Introduction to Hydraulic Design of Sewers

COURSE NO: C02-031
An Introduction to Hydraulic Design of Sewers
Course Highlights

This online engineering PDH course will introduce you to the principles of hydraulic design of sanitary sewers.  You will learn how to calculate quantities of wastewater, the approach to design of gravity and depressed sewers, required pumping capacity, hydrogen sulfide gas control, and sewer system features such as manholes, building connections, cleanouts, and pumping stations and equipment.


This 2 PDH online course is applicable to civil engineers and construction professionals seeking to understand the fundamentals of design of sewer systems.  This course will provide civil engineers and construction professional an introduction to the terminology, fundamentals and methodologies for the hydraulic design of sanitary sewer systems.

Learning Objectives

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

  • Learning how to evaluate the contributing population for the sewer system
  • Learning about Average Daily Flow, Average Hourly Flowrate, Peak Diurnal Flowrate, and Extreme Peak Flowrate
  • Learning how to calculate extreme peak flowrates from average flowrates
  • Learning how to accommodate groundwater infiltration into the sewer system when designing the sewer system
  • Learning how the Manning formula is used in design of gravity sewers
  • Learning about acceptable values for the roughness coefficient in the Manning formula
  • Learn about acceptable design velocities for gravity sewers
  • Learning the 10 parameters that need to be identified and quantified after a preliminary layout for the system has been established
  • Learning the importance of critical flow in gravity sewer design
  • Learning about velocity and flow analysis of depressed sewers
