The Norwesco 250 Gallon HD Vertical Storage Tank is a heavy-duty, vertical polyethylene tank built for above-ground bulk water storage where you need real capacity without a sprawling footprint. It stands 86 inches tall on a 31 x 31 inch base, holds 250 gallons, and carries a 1.9 specific gravity rating - the "HD" designation - so the tank wall is engineered for liquids substantially heavier than water. For straight water storage, that gives you a generous safety margin on a single Norwesco vertical tank. It ships from Fairfield, Texas, so Texas and South-Central buyers get the shortest LTL lane and the lowest freight on this model.
Will it work for your site?
This is a tall, small-footprint vertical storage tank: 86 inches of height on a 31 x 31 inch footprint. That geometry packs 250 gallons into roughly two and a half feet of ground space, which is why these vertical tanks suit tight pump houses, equipment yards, and sheds where horizontal tanks won't fit. Budget at least 90 inches of vertical clearance - the 86-inch tank plus room for fill-port and fitting access - so you can fill and service it in place. Confirm that height and your fill access before you commit a location.
Weight is what dictates your pad. Filled with water, the tank and contents reach about 2,085 pounds; against the 1.9 SG rating, the tank is built to carry up to roughly 3,962 pounds of contents - about 1.9 times the weight of plain water. That headroom means the same tank handles heavier-than-water solutions, such as brine and some agricultural or process fluids, without stepping up a model. A tank this tall and this loaded needs a level, fully supporting base - poured concrete or a continuous, flat compacted pad. The practical install sequence is to position the empty poly tank first (light enough for one or two people to set), then fill it in situ. For pad design specifics, see our guide to concrete pad sizing for above-ground polyethylene tanks, and use the Tank Sizing Calculator if you're still settling on capacity. The Tank Sizing Guide walks through matching tank size to draw rate.
Common applications and the mistake to avoid
With its high SG rating and tall vertical profile, the 250-gallon HD is a workhorse for water storage, rainwater collection, and rural and remote water reserves. If you're sizing a fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, our water-reuse tank topology guide lays out the storage train. Harvesting rain? The first-flush diverter sizing guide follows the Texas Manual on Rainwater Harvesting.
The mistake to avoid: under-building the base. The tall 86-inch profile puts the center of gravity high, and 2,000-plus pounds of filled water concentrated on a 31 x 31 inch footprint is unforgiving of a soft, sloped, or partial support. Set this Norwesco vertical tank on a full, level, load-rated pad. One more note: the outlet and fitting configuration is not published in this listing, so confirm your outlet plumbing and fitting sizes against the tank's specifications - and by phone at 866-418-1777 - before you trench or pour.
