A tall 3600 gallon black vertical tank for a tight footprint
The Norwesco 3600 gallon black vertical storage tank, part number 44790B, is a rotomolded polyethylene tank 87 inches in diameter and 151 inches tall, weighing 556 lb empty. It is a tall, slender tank: more than twelve and a half feet to the crown on a base a little over seven feet across, which puts 3600 gallons on a footprint that most tanks this size cannot match. It is rated for liquids up to 1.5 specific gravity, which covers water, rainwater, most liquid fertilizers and many of the common chemical solutions that polyethylene handles; 3600 gallons of water weighs 30024 lb. It comes with a 3 inch polypropylene female NPT bulkhead fitting with a siphon tube as the outlet and a 16 inch threaded vented manway on top. The resin is FDA compliant per Norwesco, Norwesco lists its water tanks under NSF/ANSI 61 (the listing names no models), the service limit is 120 F, and Norwesco backs it with a 3 year warranty. Black keeps light out of the contents and slows algae in stored water.

Where it goes and what it holds
Buy this shape when ground is scarce and sky is not: a water tank beside a well house, a fire reserve against the back of a building, a process water tank in a plant yard, or a bulk tank in a fenced corner where a wider tank would block the drive. The height is the thing to plan around. The manway sits at the top of 151 inches, so filling, float valve service and cleaning need a fixed ladder or a platform, and the pad needs clear sky above it. A tall tank is also less forgiving of a poor pad than a squat one: a high spot under one edge becomes a visible lean and loads one arc of the base instead of the whole circle, and a full tank is fifteen tons of water. The pad has to be flat, continuous and level under the entire 87 inch base; our guide to concrete pad sizing for above ground polyethylene tanks sets out the slab. If the tank is a fire reserve, our guide to fire water reservoir design for rural and remote sites covers sizing and freeze protection, and the industrial water reuse storage guide covers grey water and condensate collection. Anything other than water gets checked in our chemical compatibility guide first, and liquids heavier than 1.5 times water need a heavy duty tank, not this one. For the volume itself, use the tank sizing calculator and tank sizing guide.
Openings and fittings
- Outlet. A 3 inch polypropylene female NPT bulkhead fitting with a siphon tube, factory installed. The siphon tube reaches down inside the tank so the fitting can sit above the floor and still draw from near the bottom; Norwesco's drawing shows the fitting height and the tube. Your valve or pump suction threads straight into the 3 inch female thread. On a tank this tall the head pressure at the outlet is higher than on a squat tank of the same volume, so support the valve and the first length of pipe on their own within a foot of the wall and use a flexible connector before the first rigid joint.
- Manway. A 16 inch threaded vented manway on top: fill from a hose, drop a float or a level sensor in, and get a hand and a brush inside to clean. Leave the vent clear so air can move as the level changes.
- Extra ports. Only the one outlet comes installed. An overflow, a second draw or a top fill port means extra bulkhead fittings; tell us when you order and we quote them with the tank.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet position, the manway and the base profile.

One step down is the 3450 gallon vertical tank; one step up is the 4000 gallon black vertical tank. Compare their diameters and heights on their pages against your pad and your clear height, because the shape changes between sizes even when the volume is close.
Shipping and receiving
The tank ships LTL at freight class 400 from Norwesco's Hanford, California plant as an 87 by 87 by 151 inch load weighing 556 lb. It travels empty and needs a forklift with long forks, a loader with straps or a crew and a clear path to the pad; the height is what makes it awkward, not the weight. 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 44790B on the bill of lading, look over the base, the outlet fitting and the siphon tube for transit damage, and fill with water the first time before the tank carries anything else.
