1000 Gallon Doorway Water Tank

Where a thousand gallons goes on a slim footprint

This tank is bought for a barn, a shop, a pump house, a greenhouse or a basement with a walk-out double door, where the job needs a thousand gallons and the floor plan does not have room for a round tank. A well holding tank for a slow well, a fire reserve at a rural property, a rainwater store under a large roof, a process water tank beside a wall. It stands 89 inches, almost seven and a half feet, so check the ceiling and the door header. Full, it is 8340 lb of water on a 92 by 40 inch rectangle, carried entirely by the moulded base, which is why the pad is the install: level, continuous, in full contact, with no drain, joint or lip under the footprint, and on a wood structure a look underneath before the first fill, not after. Our 1000 gallon doorway tank buyer's guide goes through the common installs, the doorway tank sizing guide by application helps you confirm that a thousand gallons is the right amount, the fire water reservoir design guide covers a rural fire reserve, and the water reuse tank guide covers rainwater and grey water systems.

What goes in it

Water is the normal load, and the white wall lets you see the level through it in good light. The 1.5 specific gravity rating, a maximum of 12.52 lb per gallon, means it will also hold most liquid fertilizers and the common solutions polyethylene handles. Keep the contents under 120 F. For drinking water, keep the manway closed and the tank out of direct sun; light grows algae in standing water. To check that a thousand gallons is the right reserve, run your daily draw and your refill interval through the tank sizing calculator and take the freeboard from the tank sizing guide.

Openings and fittings

1. Outlet. A 2 inch polypropylene female NPT bulkhead fitting, factory installed low in the wall. A 2 inch valve, a camlock or a pump suction threads straight into it. Support the valve and the first length of pipe on its own so the fitting carries water, not hardware.
2. Manway. A 16 inch threaded vented manway on top: wide enough to fill from a hose or a pump, to drop a float switch in, and to get an arm and a brush inside to clean. The vent lets air in as the tank drains, so never seal it.
3. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, gives the exact outlet and manway positions.

Sizes nearby

One size down: the 750 gallon doorway water tank, which is the largest doorway tank that still passes a standard 3 foot door. If the opening is the problem and not the volume, two of the 750s side by side hold more than this tank and each goes through an ordinary door; the sizing guide above compares the family.

Shipping and receiving

The tank ships LTL on a pallet, 92 by 40 by 89 inches and 384 lb, from the nearest of Norwesco's plants in Lancaster, Ohio, Shawnee, Oklahoma and St. Bonifacius, Minnesota. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, and for a purchase order you can request a written quote. At 384 lb empty and over seven feet tall, moving it is a job for a machine or a crew, so plan the path from the truck to the opening before delivery day and have the pad ready. At the tailgate, check the part number 44045 against the bill of lading, look over the wall and the fitting for transit damage, and fill it with water the first time before it carries anything else.
