The Enduraplas 1750 gallon vertical liquid storage tank is a polyethylene bulk-water vessel that stands 89 inches tall on an 85 x 85 inch square footprint, putting a substantial reserve on a compact pad. It carries a faint green tint that cuts light penetration to slow algae growth across the long dwell times typical of potable reserve, irrigation, and rainwater storage, and it is rated to a 1.9 specific gravity. That 1.9 rating is the reason to look hard at this tank: the shell is built to hold heavier water-based liquids - brine, many liquid fertilizer blends, and ag or industrial solutions up to 1.9 SG - where a standard 1.0 to 1.5 SG vertical tank would be under-rated. For rural fire reserve, irrigation, rainwater aggregation, or general industrial water storage, this is a tank sized to do serious work without sprawling across your site.
Will it work for your site
Run the numbers before you pour a pad. Filled with plain water at a 1.0 specific gravity, this tank carries roughly 14,595 pounds of contents - about 7.3 tons sitting on that 85 x 85 inch base. Because the shell is rated to 1.9 specific gravity, the maximum rated contents weight climbs to about 27,730 pounds, near 13.9 tons, if you fill it with a denser liquid - so plan crane or forklift capacity against the load you actually intend to lift and store, not against water alone. The structure is not the limit on heavier mixes; your foundation, rigging, and freight are. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 1,750 gallons matches your actual daily draw and refill cadence rather than guessing high. The 89 inch overall height matters for inlet plumbing and any overflow access, so check your fill point and overhead clearance against that dimension before delivery.
Fittings and foundation
Fitting and bulkhead configuration - inlet, outlet, overflow, and lid size - is not listed on this record, so confirm port sizes, thread type, and gasket material for your liquid by phone at 866-418-1777 before ordering. See the technical drawing on this page for the dimensional layout. A vertical tank this heavy then lives or dies on its base. Over seven tons of water on a square footprint demands a level, continuously supported pad - a flat-bottom poly tank should never bridge across high spots or rest on point loads, or the floor knuckle takes stress it was not designed for. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework for getting that slab right. If this tank is going into a private fire-protection reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For reuse setups blending rainwater, grey water, or HVAC condensate, the industrial water reuse tank topology guide shows how to band quality across a storage train.
The mistake to avoid
The common error on a tank rated to 1.9 specific gravity is assuming that rating governs your install. It does not - it governs the tank wall. The real constraints are the 89 inch height against your overhead clearance and the contents weight against your pad and rigging. Spec the foundation for the liquid you actually intend to store, not for plain water, and confirm your access height before delivery. One wall-thickness note worth reading: vapor-saturated headspace at the top of an HDPE tank is where premature failures often begin and routine liquid-side inspection misses them - the HDPE wall thickness guide explains the ASTM D1998 sizing logic behind it.
