Norwesco 100 Gallon Black Vertical Storage Tank

Where a 100 gallon vertical tank goes

At 28 inches across and 43 inches tall this tank goes through a standard door upright and still holds a useful hundred gallons, which is why it ends up in basements, well houses, greenhouses and shop corners. Typical jobs are a holding tank ahead of a booster pump, a brine or chemical day tank for a treatment system, nutrient solution for a greenhouse, and backup water for a house on a well. Full of water it weighs 834 lb, so it needs a flat, continuous floor under the whole base; a sound slab or a solid wood floor carries it without an engineered pad. Outdoors on soil, set it on a paving slab or a bed of compacted sand so the base is supported edge to edge. Our guide to bearing surfaces under polyethylene tanks covers what the ground has to do. If you are choosing between this shape and the rest of the range, our doorway tank sizing guide walks through what each shape is for.

What goes in it

Water, liquid fertilizer and the common treatment chemicals that polyethylene handles are the normal loads. Check anything else in our chemical compatibility guide before it goes in, and ask us about anything that is not listed. Liquids heavier than 1.5 times water need a heavy duty tank, not this one, and nothing hotter than 120 F should be stored in it. For a cold climate reserve, the piece on reservoir sizing on remote sites and freeze protection is the one to read. The tank sizing calculator and tank sizing guide turn a guess at the volume into a number.

Openings and fittings

1. Outlet. A 1-1/4 inch polypropylene female NPT bulkhead fitting, factory installed low in the side wall. A valve, a hose adapter or the suction line of a pump threads straight into it. Support the valve and the first length of pipe on their own so the fitting carries liquid, not hardware.
2. Lid. An 8 inch threaded vented lid on top: room for a fill hose and a float switch, and a vent so the tank breathes as a pump draws it down. It is not an arm-sized opening; clean the tank by flushing.
3. Extra fittings. A second outlet, an overflow or a return line is a bulkhead fitting added through the wall. Tell us before the order and we quote it with the tank. Dry-fit before tightening; hand tight plus a quarter turn is enough.
4. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows where the outlet and lid sit.

The same capacity in white, where you want to read the level through the wall: the 100 gallon white vertical tank, and a second 100 gallon vertical tank in a different footprint. One step up: the 105 gallon black vertical tank, a narrower and taller shape. The colour swatches above the price switch between the versions of this tank.

Shipping and receiving

The tank ships LTL at freight class 300 from the nearest of Norwesco's plants, which include Fairfield, Texas; Griffin, Georgia; Hanford, California; Owego, New York; Shawnee, Oklahoma and Tooele, Utah. On the pallet it is 28 by 28 by 43 inches and 34 lb. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. At the tailgate, check the part number against 44328 on the bill of lading, look over the wall and the fitting for transit damage, and fill it with water the first time so any problem shows up with something harmless in the tank.
