The Enduraplas 340-gallon white vertical storage tank is a 74-inch-tall polyethylene tank on a compact 40 x 40 inch footprint, carrying a 1.9 specific-gravity rating. Read the SG number first: it tells you this tank is built to hold contents heavier than water. Plain water in it weighs 2,836 lb when full, but the tank's maximum rated contents weight is 5,388 lb. Do the arithmetic and that ceiling works out to roughly 15.8 lb per gallon across the 340-gallon volume - about 1.9 times the weight of water. For straight water storage, you are well inside the structural envelope with room to spare.
Does this Enduraplas vertical tank work for your site?
At 74 inches tall on a 40 x 40 inch footprint, this is a true vertical tank that stacks storage upward instead of spreading it across your pad - it delivers 340 gallons at roughly 1.85 feet of height per 100 gallons, so it eats far less floor space than a squat tank of the same volume. The 40 x 40 inch base means a 4-foot-square pad fully captures it. Size your slab to the 2,836 lb full-water load and treat the 5,388 lb max rated contents weight as your structural ceiling for any denser liquid down the road. The body is molded polyethylene in natural white. Run your draw and refill cycle through the Tank Sizing Calculator and the Tank Sizing Guide to confirm 340 gallons fits your demand before you commit. Storing water now but planning a denser product later? This same vertical storage tank is already rated to 1.9 SG, so you would not need to re-buy when you switch service.
Pad and setup
A vertical tank this tall wants a level, fully supporting base. Because all 2,836 lb of full-water load rides on that 40 x 40 inch footprint, the pad has to carry the weight uniformly. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that base right. If this tank is headed into rural fire-protection storage, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and if you are aggregating rainwater, grey-water, or HVAC condensate, the industrial water reuse topology guide covers banded storage trains.
The mistake to avoid
The common error on a vertical storage tank like this is ordering before you have confirmed the fitting, outlet, and gasket configuration against your plumbing. Call 866-418-1777 to confirm fitting and outlet placement and gasket material for this tank before you order, and check the technical drawing on this page - reworking connections after a 74-inch tank is set and filled is the expensive way to learn. Verify your overhead clearance too: at 74 inches the tank needs room to stand and room above it to fill.
