All About Watermains - An Insiders View

Mark E. Hughes, P.E.

Course Outline

This three hour course looks at how early watermains were constructed, the reasons for watermain construction, how water is supplied to a community and discusses the details of what factors must be considered when designing a watermain including requirements from the Environmental Protection Agency. It also gives you an overview of watermain materials, the fittings that are commonly used, how they are connected to the new watermain and how a watermain is put into service. This course will enable the designer to gain a greater understanding of what's involved in getting a watermain built and what is important for whom the main is being designed.

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course the student will be able to:

Intended Audience

This course is intended for Civil Engineers involved in the design or overseeing the construction of watermains.

Attendee Benefits for the Attendee

Attendee of this course will be able to know what's important to a municipality or client contracting the engineer to design a watermain system. They'll also know what happens in the field during the construction of a watermain and what to expect.

Course Introduction

Watermains are designed for various reasons from supplying previously unsupplied areas to replacing older or undersized mains. There are many factors to consider when designing a watermain including location of existing utilities and design criteria mandated by the Environmental Protection Agency. Selection of the type of watermain material that is specified also plays an important role depending on the physical conditions that the watermain will be subject to. Understanding how the watermain is physically constructed is also important to the design engineer so that problems during construction will be minimized by providing a set of plans that is clear and concise.
