Drainage and storm water network for a large-scale cricket stadium project. Layout covers the site infrastructure including waste (WP), soil (SP) and rain water (RW) pipe runs with precise invert levels (I.L.) and gradients like 1:100 or 1:150. Key components included: – Manholes: MH-01 (800×800) and 900×900 types with heavy-duty C.I. covers. – Pump room: 9.6m x 6.6m x 5.85m H layout with sump pump discharge details. – Kitchen drainage: Type-B grease traps and 4000x300x150mm deep channel gratings. – Sections: MH section A-A and B-B at 1:25 scale, plus sand trap and catch basin details. Pipe sizes vary from 82mm and 110mm dia. risers up to 600mm SSD mains. We’ve specified materials such as cast iron covers, G.I. frames, and S.S. sediment buckets throughout. It’s a solid template for stadium infrastructure or complex commercial drainage coordination.
