Oregon Sanitary Drainage Systems

This four-hour course on sanitary drainage systems (SDS) is designed to teach Oregon plumbers the core principles of designing, installing, and maintaining efficient systems in commercial and residential settings.

Discover what makes a proper SDS by reviewing the following:

• Proper installation practices—planning, material selection, and an overview of relevant codes commonly adopted in the United States
• Sizing methods—including assigning drainage fixture units (DFU), determining system drainage load, horizontal drainage slope using Darcy and Manning’s formula, and alternative calculation methods for sizing
• Fluid dynamics—piping layout and system design
• Alternative systems and methods—eco-friendly and sustainable practices; advanced and non-traditional sanitary drainage systems
• Grease interceptors—including installation, maintenance, and best practices for placement

Plumbers who finish this course will get a robust foundation for continued study and practice. The course also highlights the essential role of SDS in protecting public and environmental health.

After each section, multiple-choice quizzes verify your understanding of the material. Detailed answers and explanations help you identify any areas that require further review.
