The 1350 Gallon Plastic Water Storage Tank from Norwesco is a vertical polyethylene tank standing 88 inches tall on a 71-inch diameter footprint, holding 1350 gallons in a single freestanding cylinder. It is a vertical storage tank sized for rural fire-water reservoirs, irrigation supply, hauled-water cisterns, and bulk water storage where a stable, gravity-fed reserve is needed.
Will it work for your site
This vertical water storage tank is rated for a specific gravity of 1.0, which covers water and water-like fluids at that density only. For anything heavier than water, a tank rated above SG 1.0 is required, so call 866-418-1777 to confirm the right option before ordering. Filled to capacity, 1350 gallons of water weighs 11,259 pounds, which is also the maximum rated contents weight, so size your pad and base for that load. The 71-inch diameter defines the bearing area: the entire load sits on that circle, which is why a level, full-contact foundation matters more on a vertical tank than almost any other factor. Note that 1350 gallons is nominal capacity; usable draw-down depends on the outlet elevation shown on the technical drawing on this page, so size your reserve off the drawing rather than the nameplate figure. Run your demand and reserve numbers through the Tank Sizing Calculator and the Tank Sizing Guide to match real draw-down to the working volume.
Fittings and dimensions
The outlet size, lid size, and gasket configuration are not specified in the listed data for this SKU, so check the technical drawing on this page and call 866-418-1777 to confirm the exact fittings and gaskets before you plumb the tank. The drawing is also the authority for overall height versus cylinder wall height and for inlet and outlet elevations; if you are running this as a gravity-fed reserve, size your head pressure off the drawing dimensions rather than the nominal 88-inch figure.
Foundation, testing, and the mistake to avoid
The most common mistake with a tank this size is treating the pad as an afterthought. At 11,259 pounds full, an unlevel or partially supported base puts uneven hoop stress on the polyethylene wall and shortens tank life. Size and pour the slab correctly for the 71-inch footprint using the framework in Concrete Pad Sizing for Above-Ground Polyethylene Tanks, then prove the install with a controlled water fill before commissioning. The Hydrostatic Test Methodology guide walks through fill discipline, pad-settlement monitoring, and fitting-leak detection so the first 11,000-pound load is also your acceptance test.
Fire-water and reuse applications
For private fire protection on rural and remote sites, a 1350-gallon vertical reserve can serve as part of a stored-water stack; the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. If you are aggregating grey water, rainwater, or HVAC condensate, the Industrial Water Reuse Tank Topology guide shows where a vertical storage tank of this class fits in a quality-banded reuse train.
This 1350-gallon Norwesco vertical tank ships LTL freight from one plant in Washougal, WA, quoted live to your ZIP. Because LTL cost is distance-driven on a load this size, buyers outside the Pacific Northwest should run their ZIP early through our Freight Cost Estimator, or call 866-418-1777 to confirm lead time and the best freight routing for your location.
