Overview

Wastewater is a part of everyday life. Every living creature and every industry on earth creates waste in some form or another. Wastewater acts as a medium to direct waste to various treatment plants by means of sanitary sewer lines. Some sewer lines use a combination of gravity flow and flow induced by pumping systems. This 4 PDH course is Part I of a two-part series. This course will focus on the sanitary sewer lines that are under gravity flow. Part II focuses on sewer lines where wastewater flow is facilitated by the use of pumps.

This course will provide information that will guide the engineer in planning, designing and constructing sanitary sewer systems. The course materials are based solely on the materials "Sanitary and Industrial Wastewater Collection (Gravity Systems)" as published by the Army Corps of Engineers. The student will learn how to determine the pipe size and flow of sanitary sewer systems. Several calculations and nomographs are presented that will be used to design such systems. The course will also discuss the safety and operational characteristics of gravity sewer systems.

The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to earn PDH credits.

State Board Acceptance

This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states that mandate continuing education for engineers, it is the individual engineer's responsibility to determine the suitability of activities for PDH credit. The state boards typically accept online* courses that cover technical, managerial** or ethical content and which are relevant to the practice of engineering. The course must have a clear purpose or objective with a content that will maintain, improve or expand the skills and knowledge of the licensee's field of practice. For questions about your mandatory PDH requirements, visit the website of your state licensing board.

*Online courses are accepted by all state licensing boards that mandate continuing education. Other than New York (which limits online courses to 18 PDH) and Iowa (which limits online courses to 6 PDH), there are no limits placed by other states on the number of hours that can be earned through online continuing education. Consult with your state licensing board if you have any questions about the acceptability of online courses.

**The New York State Board of Engineers does not accept general office management courses, but will accept project management courses that are offered by an approved provider and that are technical in nature and contribute to the engineer's professional practice.
