An 1100 gallon low profile black water tank for a low building
The Norwesco 1100 gallon vertical water storage tank, part number 40704, is a black polyethylene tank 87 inches in diameter and 53 inches tall, weighing 185 lb empty. It holds a serious reserve under a height that most sheds, lean-tos and barn bays allow. It comes with a 2 inch polypropylene female NPT bulkhead fitting as the outlet, a 1-1/2 inch polypropylene female NPT bulkhead fitting as the inlet and a 16 inch threaded vented manway on top. It is rated for liquids up to 1.1 specific gravity, so it is a water tank; 1100 gallons of water weighs 9174 lb. The resin is FDA compliant and UV stabilized, the service limit is 120 F, and Norwesco backs it with a 3 year warranty. Black stops light through the wall and with it the algae that light feeds.

Where the low 1100 goes
Buyers pick this shape when the tall 1100 will not clear the roof. At 53 inches the manway is at chest height, so a float valve, a level sensor and a cleaning brush all go in from the ground. The cost of that is an 87 inch footprint, and the whole circle must sit on a flat, level, continuous base: this is not a tank for four blocks and a sheet of plywood. Compacted gravel in a frame works for many sites; a slab is the permanent answer, and the concrete pad sizing guide explains how to size it. Typical uses are household reserve on a well, rainwater off a house roof, stock water at a barn, and the water side of a small spray rig fill station. For a rural fire reserve, the fire water reservoir design guide covers how volume, draft connections and freeze protection fit together. If the tank will collect roof water or grey water for reuse, the water reuse storage guide is the place to start. Confirm the volume against the demand with the tank sizing calculator and the tank sizing guide.
Openings and fittings
- Outlet. A 2 inch polypropylene female NPT bulkhead fitting low in the wall. A 2 inch valve threads in directly. Support the valve and the first length of pipe on their own so the fitting carries water, not hardware.
- Inlet. A 1-1/2 inch polypropylene female NPT bulkhead fitting for the fill line from a pump or a downspout.
- Manway. A 16 inch threaded vented manway on top, large enough for a float assembly and an arm.
- Rating. 1.1 specific gravity, a maximum of 9.18 lb per gallon. Water only in practice; liquid fertilizers are heavier and belong in a tank rated 1.5 or higher. Contents under 120 F.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the fitting heights and positions for your pipe layout.

Shipping and receiving
The tank ships LTL at 170 lb from the nearest of Norwesco's plants: Fairfield, Texas; Griffin, Georgia; Hanford, California; Lancaster, Ohio; Owego, New York; Shawnee, Oklahoma; Tooele, Utah or Washougal, Washington. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, or request a written quote. An 87 inch tank is wider than a pallet jack wants to handle, so plan for two or three people or a forklift at delivery. At the tailgate, check the part number against 40704 on the bill of lading, look the shell over for transit damage, and run the water fill acceptance test on the pad before the tank carries anything else.
