A 75 gallon black vertical tank that stands in a 23 inch circle
The Norwesco 75 gallon black vertical storage tank, part number 43785, is a polyethylene tank 23 inches in diameter and 49 inches tall, weighing 28 lb empty. It is a tall, narrow tank for a spot where floor space is tight and height is not: a utility room, a pump house, the corner of a greenhouse or a wash bay. It comes with a 1-1/4 inch polypropylene female NPT bulkhead fitting at the outlet and an 8 inch threaded vented lid on top. The tank is rated for liquids up to 1.5 specific gravity, which covers water, most liquid fertilizers and many common chemicals; 75 gallons of water weighs 626 lb. The resin is FDA compliant, Norwesco lists the tank as NSF 61, the service limit is 120 F, and Norwesco backs it with a 3 year warranty. Black keeps light out, which stops algae in stored water.

Where it goes
At 49 inches tall with the lid on top, the tank needs a little more than that in headroom to fill and inspect; measure the ceiling before you order, especially under a stair or in a crawl space. The 23 inch footprint fits through any door and beside most equipment. Typical duties are a pressure tank or make-up water reservoir in a pump house, a day tank feeding a chemical pump, a rainwater or condensate collection tank indoors, and a reserve for a small fire pump or a sprinkler test loop. For the larger version of those jobs, our guides to water reuse tank layouts for grey water, rainwater and condensate and fire water reservoir design for rural sites explain where a small poly tank fits in the system. It needs a flat, continuous surface under the whole base; on a new outdoor pad, see our guide to concrete pad sizing for above ground polyethylene tanks.
What goes in it
Water, fertilizer solution and the treatment chemicals that polyethylene handles are the normal loads. Check anything stronger in our chemical compatibility guide before it goes in, and keep the contents at or below 120 F. Liquids heavier than 1.5 times water belong in the heavy duty version of this tank, linked below. For the volume, the tank sizing calculator and tank sizing guide walk through the choice.
Openings and fittings
- Outlet. A 1-1/4 inch polypropylene female NPT bulkhead fitting, factory installed low in the side wall. A 1-1/4 inch ball valve, a hose adapter or a pump suction threads straight in. Dry-fit the valve so the handle clears the wall, and support any pipe on its own so the fitting carries liquid, not weight.
- Lid. An 8 inch threaded vented lid on top: big enough to fill from a hose, drop a float in, and get a brush inside. Keep the vent clear so a pump can draw without pulling the walls in.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the exact outlet and lid positions.

Shipping and receiving
The tank ships LTL at freight class 300 from the nearest of Norwesco's plants, 23 by 23 by 49 inches and 28 lb; Norwesco moulds this size across the country, so the lane is usually short. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, or request a written quote. One person can carry it. At the tailgate, check the part number against 43785, look at the bulkhead fitting for transit damage, and fill it with water the first time before it carries anything else.
