The Enduraplas 1350 Gallon Black Vertical Storage Tank is a 1,350-gallon polyethylene vertical tank built for bulk water storage. At 71 inches tall on an 85 x 85 inch base, the wide footprint keeps the tank stable at full load while holding serious volume on a single pad, and the black wall helps slow algae growth in outdoor service.
Will it work for your site?
This is a vertical storage tank rated to 1,350 gallons with a 1.9 specific gravity wall rating, which gives you real headroom over plain water. Full of water, the tank plus contents weighs roughly 11,259 pounds, and at its maximum rated contents weight it carries up to 21,392 pounds. Those loaded figures, not the empty tank, drive your pad and foundation decisions, so size the slab to the maximum rated weight. Use our Tank Sizing Calculator and the Tank Sizing Guide to match the 1,350-gallon capacity and 85 x 85 inch footprint to your draw rate. Fitting size and placement on this vertical storage tank are confirmed at order, so call 866-418-1777 before you plumb it in, and review the technical drawing on this page for the as-built layout.
Foundation and placement
An 85 x 85 inch footprint carrying over 21,000 pounds at maximum rated load needs a properly engineered base. A poured concrete pad sized to the loaded weight is the right approach for a tank this size; our guide on Concrete Pad Sizing for Above-Ground Polyethylene Tanks walks through the ACI framework for getting that pad right. If this tank is going into a fire-water reservoir or rural water-supply role, our Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing and cold-climate freeze protection. For reuse setups, the Industrial Water Reuse Tank Topology guide shows how to band grey-water, rainwater, and HVAC condensate into staged storage trains.
The mistake to avoid
The common error on a tank this size is treating the 1.9 specific gravity rating as a license to store anything. That rating describes how heavy a liquid the polyethylene wall can safely hold, not chemical resistance. This is a water-storage tank; on any service heavier or more aggressive than water, the gasket and fitting materials become the limiting factor, not the wall, so confirm seal compatibility before filling. The other frequent miss is sizing the pad to the water-only weight instead of the 21,392-pound maximum rated contents weight.
This tank ships LTL freight from the nearer of two plants, Converse, TX or Neche, ND, so a buyer in the central or southern US draws the Texas lane while the northern plains draw North Dakota, which keeps the haul shorter and the rate lower than a single-warehouse competitor.
