Sewers and Sewerage

Basic Civil Engineering – Sewers and Sewerage                                        

Course Description
Piping, underground structures and pumps are just a few of the items needed when moving wastewater to an area where it can be treated. When designing sewerage, there are different methods to look at, and there are pitfalls you must be careful to avoid.
In this course, we will look at types of pipe, manholes, lift stations, force mains, and regulations.
Learning Objectives

At the conclusion of this course, you will be able to: 

  • Recall the terminology and history associated with sewerage projects
  • Perform the necessary tasks to ensure the sewerage job is completed successfully
  • Identify the types of sewer lines
  • State current regulations for sanitary sewer overflows
Introduction

During a visit to Crete, we toured an excavation of a large building that they were uncovering. We were told that it was built in 3000 BC. One item of interest was what was described to us as the “bathroom.” It was in the center of the building on the second floor, and consisted of an area about 4 feet square. It appeared that originally, there were walls on two sides and just a 3 inch high sill on the other two sides. There was a gouged out trough behind the sill leading up to a hole in the floor about 2 inches in diameter. The trough started about 1/4 inch deep and was 2 inches deep when it got to the hole. It appeared that water was introduced from above and was collected and conveyed away below. At that point, they had no
