This week-long workshop will be an immersion in constructed wetlands for wastewater treatment. Students will be introduced to the basic principles of domestic wastewater treatment with natural systems and explore the major design considerations including treatment requirements, process flow diagrams, and process selection. We will cover system analysis, site investigation, permitting, treatment options, design basics and material selection. The course will also cover design history and current design theory. We will spend a day visiting constructed wetlands in the area. Students are encouraged to bring specific projects to work through design considerations.  After completing the course, students will be able to design and build a small constructed wetland for wastewater treatment.

Course start time: Sunday, 5pm
Course end time: Friday, 5pm

 

  • Competency Level: Beginner to Intermediate
  • AIA credits: 35 HSW Learning Units

Materials to bring

  • Something to take notes: clipboard with paper or notebook
  • Your favorite calculator (we will have some extras)
  • Comfortable clothes / shoes: we will be sitting some, working outside a least a few days, and traveling
  • around visiting sites... so comfortable clothes that you don't mind getting a little dirty.
  • Any information on wastewater projects that you are working on or may be working on in the future
  • o Site information: maps, survey, soils information, climate data, etc.
  • Your imagination and creativity: ...to balance the three engin-nerds teaching this class.
