Course Overview

Expand Your Knowledge of Private Onsite Wastewater Treatment Systems (POWTS)

Designing a reliable, new onsite sewerage system or trouble-shooting an existing system requires knowledge of soils, various contaminants, and the treatment processes that are available to remove them. Learn about why drainfields fail, causes of septic tank corrosion, and more. This course will provide valuable knowledge for providing reliable onsite wastewater solutions.

This event is sponsored by the Wisconsin Department of Safety and Professional Services (DSPS).

Continuing Education Credit

All attendees will earn 6 PDH (or 0.6 CEU) for attending. The course has also been approved for the following Wisconsin-specific credentials: JP, JPRS, MP, MPRS, POWTS Inspector, POWTS Maintainer, and CST.

Who Should Attend?

  • Wastewater engineers
  • Consulting designers
  • Soil Testers
  • Inspectors
  • Installers
  • POWTS Maintainers
