Tanks Details 2x2 Manhole 1x1 Hole 9x9x18 PCC 1 3 6 DWG Plan

This AutoCAD DWG file provides complete tank details, including underground water tank section, overhead water tank section, septic tank detail, and typical stair construction detail with precise reinforcement and material specifications. The drawing includes an underground water tank section with 3 by 4 inch cement plaster mixed with 2 point 5 percent puddle, water level indication, and reinforcement bars such as 3 bars at 8 inch and 3 bars at 7 inch spacing. The overhead water tank section includes a pedestal size 9 inches by 9 inches by 18 inches with PCC 1 ratio 3 ratio 6 base, slab reinforcement, and a manhole size 2 feet by 2 feet. The septic tank detail shows internal partition walls, inlet and outlet connections, 1-foot by 1-foot inspection holes, and PCC 1 ratio 3 ratio 6 foundation with proper base thickness. The drawing also includes a typical stair detail with beam size 9 inch by 18 inch, riser and tread reinforcement using 3 bars at 8 inch and 4 bars at 6 inch spacing, and PCC 1 ratio 4 ratio 8 base. Additional details such as 2 number 4 bars, L by 4 anchorage lengths, and slab thicknesses are clearly marked for construction accuracy. This tank and stair CAD drawing is highly useful for architects, civil engineers, and builders requiring detailed structural layouts and reinforcement information.
