This Septic Tank Detail DWG file provides a complete construction drawing of an underground septic tank system with sectional detailing. The drawing illustrates reinforced concrete walls, base slab, and cover slab with finished floor level clearly marked. Internal chamber layout shows inlet and outlet pipe positions, flow direction, slope for wastewater movement, and central inspection access. Layers such as compacted subgrade, concrete blinding, reinforced concrete base, and surrounding natural soil are clearly identified. Dimensions for tank depth, wall thickness, slab levels, and pipe alignment are accurately mentioned to support correct construction execution.
