The Enduraplas 870 gallon dark green vertical water storage tank is a polyethylene vertical tank built for above-ground bulk water storage on farms, ranches, fire-water reservoirs, rural water systems, and industrial reuse trains. It holds 870 gallons, stands 78 inches tall on a 60 by 60 inch footprint, and is molded in dark green to reduce light transmission through the wall. The tank carries a 1.1 specific gravity rating, a durability margin built into the wall for above-ground water service.
Will this tank handle your job?
This is a true vertical storage tank: a 60 by 60 inch footprint rising 78 inches, which gives you real capacity without sprawling across your pad. Filled with water, the tank and its contents weigh roughly 7,256 pounds, and the wall carries a 1.1 specific gravity rating with a maximum rated contents figure of 7,981 pounds. Plan your pad and supports around the full-water figure, not the empty shell. The 60 by 60 inch footprint is what your concrete or compacted base has to carry, so size the pad to the full load and keep it level and continuously supported. If you are not sure whether 870 gallons matches your draw and refill cycle, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a size.
Fittings and the technical drawing
For fitting locations, port placement, and exact dimensional callouts, see the technical drawing on this page rather than working from the headline numbers alone. The drawing is the authority for where outlets and lids land, which matters when you are plumbing the tank into a manifold or aligning it with existing infrastructure. Confirm those locations against your site plan before you set the tank, because moving a plumbed-in vertical tank after the fact is a real chore. Fitting and gasket kits can be quoted to your spec, so call 866-418-1777 with your plumbing plan before the tank ships.
How it ships and the mistake to avoid
This vertical storage tank ships LTL freight from the Enduraplas plant in Converse, TX, with the cost quoted live to your ZIP code. Get your number from the Freight Cost Estimator or call us at 866-418-1777. The most common mistake on a tank this size is underbuilding the foundation: at over 7,200 pounds full, an unlevel or undersized pad will stress the tank wall and shorten its life. Read our guide on concrete pad sizing for above-ground polyethylene tanks before you pour, and once the tank is set, follow our hydrostatic test methodology to verify the install and watch for pad settlement on first fill. For rural fire-protection storage, our guide on fire-water reservoir tank design covers NFPA 22 sizing and freeze protection for cold-climate service, and if you are aggregating grey-water, rainwater, or HVAC condensate, see our industrial water reuse tank topology guide.
