The Norwesco 3450 Gallon Plastic Water Storage Tank (SKU N-44664) is a vertical polyethylene tank built for bulk water storage, fire reserve, irrigation, and process water supply. It stands 119 inches tall on a 96-inch-diameter footprint and holds 3,450 gallons. If you are sizing a vertical storage tank for a fixed pad and want a single large-volume vessel rather than a manifolded bank, this is the size where pad design and freight planning matter as much as the tank itself.
Will it work for your site?
This is a Norwesco vertical water tank rated to a specific gravity of 1.0, the standard rating for water and water-density contents. Here are the numbers to design around:
- Capacity: 3,450 gallons
- Full water weight: 28,773 lb (also the maximum rated contents weight at SG 1.0)
- Footprint: 96 in diameter
- Height: 119 in
Plan the slab for that full water weight of 28,773 lb (about 14.4 tons as a straight unit conversion). Size and reinforce the pad so it carries that load without settling or point-loading the tank floor. Walk through the load math with our Tank Sizing Calculator and the Tank Sizing Guide before you pour, and review concrete pad sizing for above-ground polyethylene tanks for the ACI 360R-10 framework that applies to a tank this heavy. Outlet and fitting size, count, and placement are not configured in this listing — confirm them, along with gasket selection, against the technical drawing on this page or by phone before you order.
Common uses and a mistake to avoid
At 3,450 gallons this size lands in fire-water reserve, rural and remote water supply, irrigation buffering, and industrial water reuse trains. If you are building a private fire-protection reservoir, read fire-water reservoir tank design for the NFPA 22 sizing discipline and cold-climate freeze protection that govern usable volume. For grey-water, rainwater, or HVAC condensate aggregation, the industrial water reuse tank topology guide covers quality-banded storage trains. The mistake to avoid on a vertical tank this large is commissioning it without a controlled water fill: fill it in stages on a monitored pad so you catch settlement and fitting leaks before the tank reaches 28,773 pounds. Our hydrostatic test methodology walks through the water-fill discipline, hold-time math, and pad-settlement monitoring for new-install acceptance. One more thing: the 1.0 specific gravity rating matches this tank to water and water-density fluids only. For anything heavier than water, you need a tank with a higher specific-gravity rating, and you should confirm fitting and bulkhead gasket material is compatible with your fluid against the drawing.
Freight and ordering
This vertical storage tank ships LTL freight FOB Fairfield, TX, with freight quoted live to your ZIP code. A 119-inch-tall, 96-inch-diameter vessel is a tall, oversized freight item, so pull your freight cost with the Freight Cost Estimator before you order, and tell us about site access for the delivery truck.
