Choose appropriate drainage pipe materials for sanitary systems by evaluating PVC, UPVC, CPVC, HDPE, and PE against application, installation conditions, and code requirements to ensure durable, code-compliant installations.
Understand the external drainage network with inspection chambers and manholes as access for inspection, cleaning, and maintenance, including benching, invert levels, and cover selection to support gravity flow.
Compare septic tanks and holding tanks for on-site wastewater, explain basic treatment versus storage, and outline sizing and design considerations like soil conditions, groundwater levels, and environmental regulations.
Learn a complete sanitary drainage workflow: review fixtures, determine DFU values, size pipes to code, verify slope and invert levels for gravity flow.

Welcome to the Complete Sanitary Drainage Design Masterclass presented by Engineering Hub Academy!
Sanitary drainage design is an essential part of plumbing and MEP engineering. Every building needs a reliable drainage system to safely collect and discharge wastewater from toilets, wash basins, showers, kitchens, floor drains, and other plumbing fixtures.
In this course, you will learn the fundamentals of sanitary drainage systems and understand how drainage networks are designed, sized, routed, installed, and coordinated in real building projects.
The course covers key topics such as sewage types, drainage system arrangements, pipe materials, pipe installation requirements, gravity flow, pipe slopes, Drainage Fixture Units, pipe sizing, drainage routing, cleanouts, floor drains, interceptors, inspection chambers, manholes, sump pumps, septic tanks, holding tanks, and AI-assisted plumbing design.
You will also go through practical calculation examples related to pipe slope, invert levels, DFU calculation, sump pump head, sump pit volume, septic tank sizing, and holding tank sizing.
