Norwesco 1550 Gallon Black Heavy Duty Vertical Storage Tank

Why heavy duty, and why this shape

Full of water this tank holds 12927 lb of liquid; full of a liquid at the 1.9 rating limit it holds about 24560 lb. The heavy duty wall is built for the second figure. Buy it when the liquid is heavier than water, when the tank cycles full and empty often, or when the 5 year warranty is worth the extra weight. The 67 inch height is what gets it under a barn eave, a lean-to, a carport or a low shop ceiling, and lets you fill and inspect it from the ground. The trade is 87 inches of footprint: over seven feet of flat, level, continuous floor, sized for the full weight. Our guide to the pad sizing framework for above ground polyethylene tanks covers thickness and margin. For roof water, see diverter sizing for rainwater harvesting; for a rural fire reserve, our reservoir design article; for a train of tanks storing liquid by quality, the piece on quality banded storage trains. Check the volume with the tank sizing calculator and the tank sizing guide.

Openings and fittings

1. Outlet. A 2 inch polypropylene female NPT bulkhead fitting, factory installed low in the sidewall. A 2 inch ball valve, camlock or hose adapter threads straight in. Dry-fit it facing the pipe run, tighten, and support the valve and the first length of pipe on their own.
2. Manway. A 16 inch threaded vented manway on top for the fill line, a float switch and a cleaning brush. Keep the vent clear.
3. Liquid and temperature. At or below 1.9 specific gravity and at or below 120 F. Check anything other than water against polyethylene before the first fill.
4. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet height and the manway position.

Shipping and receiving

The tank ships LTL at freight class 400, upright, 87 by 87 by 67 inches and 249 lb, from the nearest of the Norwesco plants that build it: Fairfield, Texas; Griffin, Georgia; Hanford, California; Lancaster, Ohio; Owego, New York; Petersburg, Texas; Shawnee, Oklahoma; Sheldon, Iowa; St. Bonifacius, Minnesota; Tooele, Utah; or Washougal, Washington. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. Without a forklift at the stop, plan on three people to roll it off and walk it to the pad. At the tailgate, check the part number 40236B against the bill of lading, look over the sidewall and the bottom edge for transit damage, and fill it with water the first time before anything heavier goes in.
