Engineered Plumbing Design II – Alfred Steel | Lecture 10 – Kitchen & Indirect Waste Drainage

This is the 10th lecture in our Arabic series exploring Engineered Plumbing Design II by Alfred Steel, alongside SBC 701 and its commentary. We discuss kitchen waste and indirect drainage, focusing on code requirements and practical installation considerations. Topics include: Commercial kitchen drainage: food-preparation sinks, washing sinks and dishwashers. Indirect connections to grease interceptors. Air gaps versus air breaks: applications and sizing. Walk-in refrigerator and freezer floor drains. Potable and nonpotable clear-water waste. Indirect waste piping: trapping and length limits. Waste receptors: selection, sizing, access, hub drains and standpipes. For junior engineers and anyone developing their plumbing design knowledge. #PlumbingDesign #KitchenDrainage #IndirectWaste #DrainageSystems #SBC #MEP #BuildingServices
