Norwesco 1550 Gallon Black Vertical Storage Tank

Where the short, wide tank wins

Under a barn eave, a lean-to, a carport, a low pump house roof or a deck, 67 inches of height is what gets the tank in. The same height lets you fill, look in and clean it standing on the ground, and the low centre of gravity suits a windy site. The trade is the footprint: 87 inches is over seven feet of clear, flat, level floor the whole way round, and a full tank puts well over six tons on it, so a poured pad or an existing slab is the normal base. Compacted gravel needs a sand cap; stones print into the floor of a full tank. Our guide to the pad sizing framework for above ground polyethylene tanks gives thickness and edge margin. If the tank collects roof water, read the first flush diverter sizing guide before plumbing the inlet. For a rural fire reserve see reservoir design for rural and remote sites; for grey water or condensate storage, the reuse tank topology piece. 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 so the tank breathes as the level moves.
3. Liquid and temperature. At or below 1.5 specific gravity and at or below 120 F. Heavier liquids belong in the heavy duty version below. 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 220 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 N-40235B 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 it carries anything else.
