  • Overview
  • Syllabus
  • Instructor
  • Location


After participating in this course you will be able to:

  • Analyze existing systems for any possible problems, maintenance and rehabilitation
  • Use the software packages: US-EPA SWMM
  • Recognize the numerous issues to consider when planning sewer and stormwater drainage systems at a given site
  • Design sanitary sewer and stormwater drainage systems to meet given planning objectives

Eighty percent of a municipality’s problems are caused by twenty percent of its sanitary sewers and stormwater drainage systems. The best way to avoid the majority of future problems is to pay greater attention to them during the design phase. This four day workshop is aimed at those who want to hone their skills in sanitary sewer and stormwater drainage systems design, and stormwater management.

In a workshop setting, under the guidance of your instructor, you will complete a sanitary sewer and stormwater drainage system design as well as use a case study to discuss and develop a plan to mitigate the environmental impact caused by urban development and the management of stormwater.
