Septic Tank Section Details DWG with Capacity Layout and Dimensions

This AutoCAD DWG file includes detailed septic tank drawings with plan and section views prepared for multiple buildings, such as special lecture buildings, library buildings, administration buildings, dormitories, and assembly halls. The drawings clearly indicate septic tank capacities ranging from 7.0 cubic meters to 15.0 cubic meters, internal chamber layouts, vent pipe positions, sewage pit connections, and concrete cover dimensions. Section details show waterproof concrete with cement mortar steel trowel finish, partition walls between chambers, PVC pipe sizes of 100 mm diameter, vent pipes with insect screens, and finished ground levels. Accurate horizontal and vertical measurements are provided in millimeters, including overall tank lengths, chamber widths, wall thicknesses, slab depths, and cover slab sizes. These septic tank section details DWG drawings are suitable for external drainage system design, construction detailing, and technical documentation for architects, civil engineers, and builders working with AutoCAD-based workflows, with reference to compact condominium floor plan drawings prepared with clear light layout coordination and professional drafting standards.
