Pressure and Gravity Sewers

COURSE NO: C02-068
PDH CREDIT: 2
COURSE PROVIDER: Elie Tawil, P.E., LEED AP
Pressure and Gravity Sewers
Course Highlights

This online engineering courses is divided in to two parts: The first part discusses sewer systems that use pressure to deliver sewage to a treatment system. The second part discusses small diameter gravity sewers (SDGS) which convey effluent by gravity from a tank to a treatment location. Each part presents an overall description of the relevant topic along with the advantages and disadvantages of each system, design criteria, performance data, operation and maintenance and insights about cost related data.

 

Alternative wastewater collection systems can be cost effective for homes in areas where traditional collection systems are too expensive to install and operate. Pressure and gravity sewers are used in sparsely populated or suburban areas in which conventional collection systems would be expensive. These systems generally use smaller diameter pipes with a slight slope or follow the surface contour of the land; thereby, reducing excavation and construction costs. These systems convey effluent by gravity from an interceptor tank (or septic tank) to a centralized treatment location or pump station for transfer to another collection system or treatment facility.

 

This 2 PDH online course is applicable to civil, mechanical and environmental engineers, as well as design and construction personnel involved with the planning, design and installation of low pressure and small diameter gravity sewer systems.
Learning Objectives

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

  • Learning about the common types of alternative wastewater collection systems
  • Understanding the advantages and disadvantages of each type of system
  • Understanding the applicability of each system
  • Familiarizing with the design criteria,  performance data and  operation and maintenance processes of each system
  • Ability to compare conventional wastewater collection systems to alternative wastewater systems
Course Document
In this professional engineering CEU course, you need to review the document titled, “Pressure and Gravity Sewers” which is based on a compilation of the USEPA Wastewater Technology Fact Sheet, “Sewers, Pressure” and Decentralized Systems Technology Fact Sheet, “Small Diameter Gravity Sewers”.

Course Quiz
Once you complete your course review, you need to take a multiple-choice quiz consisting of fifteen (15) questions to earn 2 PDH credits. The quiz will be based on this USEPA publication.
The minimum passing score is 70%. There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
Certificate of Completion

Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you may print your Certificate of Completion after we receive your payment.) For your convenience, we will also email you your Certificate of Completion. Also, you can log in to your account at any time to access and print your Certificate of Completion.
