Rainwater Drainage Tank Detail Plan Section Pipe Layout Design

The Rainwater Drainage Tank Detail drawing presents a technical layout illustrating the design and construction details of a rainwater drainage tank system used in building infrastructure. The drawing includes plan views and sectional details that show the internal structure of the drainage tank, wall thickness, inlet and outlet pipe connections, and overflow arrangement. The layout clearly demonstrates how rainwater is collected and directed through drainage pipes into the storage or discharge chamber. Structural elements such as tank base slab, side walls, and cover slab are also illustrated to provide a clear understanding of the tank construction configuration used in drainage system planning.
