175 Gallon Vertical Liquid Storage Tank

Where it goes

Thirty-one inches across and 60 inches tall is a tank that holds two or three days of draw on most small systems with the top at eye height, so filling from a hose or a pump line is easy and checking the level by eye is possible. It stands in a plant room as a make-up or chemical feed tank, on a wash bay as a rinse tank, in a barn or a greenhouse as a water or nutrient tank, or in a well house as a holding tank. Thirty-one inches is wider than a standard doorway, so measure the opening it has to pass through; most double doors and every roll-up door take it upright. Full of water it puts about 1460 lb on a 31 inch circle, and a rotationally moulded base bears on everything it touches and nothing else, so it needs a flat, continuous, level surface under the whole base: a slab, a solid deck or a full sheet of plywood over joists, never two bearers with air between them.

What goes in it

Water, liquid fertilizer, wash water and the treatment chemicals that polyethylene handles are the normal loads. A 1.5 specific gravity rating means liquids up to 1.5 times the weight of water; concentrated acids and some brines are heavier than that and need a heavy duty tank. Tell us the liquid and the temperature it will be stored at and we will say whether this is the right tank. Our buyer's guide to the 175 gallon natural white vertical tank covers placement and plumbing for this capacity, and the tank sizing calculator and tank sizing guide settle whether 175 gallons is enough for your draw.

What to check before you buy

1. The fittings. Norwesco vertical tanks of this size normally ship with a bulkhead fitting low in the wall and a threaded vented lid on top. Call us with the part number and we will confirm the outlet size and lid on this one before it ships, so the valve you buy threads straight in.
2. The doorway. 31 inches across. Measure the opening, including the turn at the top of any stairs.
3. The surface. Flat, level and continuous under the whole base.
4. The valve. Dry-fit it so the handle swings clear of the wall before you seal the threads, and support the first length of pipe on its own so the fitting carries liquid, not hardware. Never pump out of a polyethylene tank with the top sealed; air has to get in as the level falls.
5. The temperature. Polyethylene storage tanks are for ambient and warm liquids, not hot process water. Tell us the temperature if it is above room temperature.

Shipping and receiving

The tank ships from Norwesco's Owego, New York plant, 31 by 31 by 60 inches at a ship weight of 34 lb. It is light for its size, so the lane matters more than the weight. The listed price is before freight; the freight cost estimator gives the cost to your ZIP. At the tailgate, check the part number 45872 on the bill of lading, look over the base and any fitting for transit damage before signing, and fill it with water the first time before it carries anything else.
