Septic Tank Plan and Section AutoCAD Drawing with Structural Details

This AutoCAD DWG file presents a detailed septic tank plan and sectional drawing prepared with clear construction dimensions and material specifications. The drawing includes a complete plan view and sectional elevation showing internal chambers, inlet and outlet arrangements, and proper flow direction. Structural elements such as 9-inch thick brick masonry walls, internal partition walls, base slab, and top RCC slab are clearly marked. The plan indicates overall tank size, internal clear dimensions, chamber spacing, wall thickness, and manhole cover locations, making it suitable for residential and small commercial sanitation planning.

The sectional detail illustrates construction layers, including PCC 1:4:8 below the base slab, PCC 1:2:4 flooring, RCC top slab, and uPVC inlet and outlet pipes with accurate levels. Depth details, chamber heights, and reinforcement zones are well defined to support execution on site. This DWG drawing is ideal for architects, civil engineers, builders, and plumbing consultants who require a standard septic tank reference for approval drawings, working drawings, or construction documentation.
