• Sizing methods—including assigning drainage fixture units (DFU) and 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 and maintenance and best practices for installation and placement

Participants will gain foundational knowledge and insight for further study and practice. This course emphasizes the importance of SDS in public health and environmental protection.
