The Enduraplas 1750 Gallon Black Vertical Water Storage Tank is a polyethylene vertical tank rated to hold 1,750 gallons, built for above-ground bulk water storage where you need a large reservoir on a compact pad. The black color blocks light to discourage algae growth, making it a practical choice for long-term water holding. It stands 89 inches tall on an 85 x 85 inch footprint, and carries a 1.1 specific gravity rating, so it is built around water-density service rather than heavier liquids.
Will it work for your site?
Size the pad and the plumbing around real loaded weight, not the empty shell. Filled to 1,750 gallons of water this tank carries roughly 14,595 pounds of contents, and at its maximum rated contents weight it reaches about 16,055 pounds. The 85 x 85 inch footprint means you need a level pad at least that wide on every side, and the 89 inch standing height puts the fill point well overhead, so plan ladder, fill-line, and overflow access before delivery. This compact footprint at 1,750 gallons is why this size shows up so often as a vertical water storage tank for rural homes, fire-water reserve, ranch supply, and rainwater aggregation. If you are weighing this against other capacities, run your demand numbers through the Tank Sizing Calculator and read the Tank Sizing Guide before you commit.
Pad and install discipline
A vertical tank this tall and this heavy lives or dies on its base. Pour and cure a level pad sized to carry the full 16,055 pound rated load, then verify the install before you trust it. Our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide walks the ACI 360R-10 framework, and the Hydrostatic Test Methodology guide shows how to water-fill for acceptance, monitor pad settlement, and check fittings for leaks during the hold time. For fire-protection reservoirs and cold-climate sites, see our guides on fire-water reservoir tank design and industrial water reuse topology for grey-water, rainwater, and HVAC condensate trains. The technical drawing on this page gives the dimensioned reference for fitting and overflow placement.
The mistake to avoid
The common error on a tank this size is treating the 1.1 specific gravity rating as a license to store anything liquid. This tank is rated for water-density service; it is not specified here for heavier chemicals or higher-SG liquids. If your liquid is denser than water, you need a tank with a higher SG rating, not this one. Equally important, confirm the fitting, gasket, and outlet plan for your fluid and operating temperature before you plumb the tank, since the right bulkhead and gasket selection is what keeps a fitting leak-free under the loaded head pressure. Do not undersize the pad or the supply line for the loaded weight figures above.
