The Norwesco 750 Gallon Vertical Water Tank is a 750-gallon polyethylene storage tank built for above-ground water service. It stands 107 inches tall on a 46 x 46 inch footprint, so it holds substantial volume without spreading across a large pad area. The tank is rated to a specific gravity of 1.0, which matches fresh water and confirms it is sized for water duty rather than heavier liquids. When you need a Norwesco vertical tank in the 750 gallon class for irrigation supply, rainwater holding, or rural fire-water reserve, this is the size that fits a tight footprint while keeping head height for gravity feed.
Will it work for your install?
Filled to capacity with water, this tank carries 6,255 pounds of contents. That full-water weight is the number your pad and base have to support, so plan the foundation around it before delivery rather than after. Size the pad to at least the 46 x 46 inch footprint plus edge margin, and keep it dead level. For above-ground polyethylene tanks this size, a properly sized concrete pad is the difference between decades of service and a settlement crack; our concrete pad sizing guide walks the ACI 360R-10 framework for exactly this load. If you are still choosing a size, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to draw and refill rate.
Fittings and outlets
The tank ships configured with a 1-1/2 inch standard bulkhead fitting and a 2 inch standard bulkhead fitting for plumbing your supply and outlet lines, plus a 16 inch vented manway on top for fill access and air exchange as the level rises and falls. Both bulkheads are standard gasketed connections, so confirm the gasket material suits your fluid before you plumb in, since the gasket is the seal that does the work. The vented manway matters too: it lets the tank breathe during fast fill and draw so you do not pull a vacuum on the sidewall. Confirm fitting heights and orientation against the technical drawing on this page before you trench or set your plumbing, since outlet placement drives your pad layout and valve runs.
The mistake to avoid
This tank is rated at 1.0 specific gravity, which means it is engineered for water and other liquids no heavier than water. Do not press it into service for a denser liquid; anything above 1.0 specific gravity belongs in a higher-rated tank, and overloading a 1.0 tank stresses the wall beyond its design. Keep this one on water duty and it will earn its keep. One more habit that pays off: the 16 inch vented manway is your vacuum safeguard during fast fill, so never cap or seal it off. For new installs, run a hydrostatic acceptance test after setting, and if you are designing a rural or remote fire-water reserve, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
