The Norwesco 2500 gallon vertical liquid storage tank is the high-headroom option in this size class: it carries a 1.9 specific gravity rating, meaning the wall is engineered for liquids up to 1.9 times the weight of water. For water, rainwater, or fire-protection reserve that is far more wall than plain water demands, so the tank runs at the conservative end of its design envelope - and the same rating means one tank can later be repurposed for heavier liquids without buying a different vessel. The body is molded from high density linear polyethylene in blue, holds 2,500 gallons, and seats on a 102 by 102 inch footprint. Molded gallon indicators on the side let you read volume at a glance.
Will it work for your site
Plan around the loaded weight, not the empty shell. Filled with water this vertical storage tank carries roughly 20,850 pounds of contents; at its full 1.9 specific gravity rating it can hold up to 39,615 pounds of liquid. Either number calls for a pad that is flat, level, and continuously supported across the entire 102 by 102 inch footprint - poured concrete or a properly compacted base, never blocking or partial bearing. A tank this size is unforgiving of an out-of-level base, so confirm the pad before delivery. To square the 2500 gallon capacity against your draw rate and refill schedule, work through the Tank Sizing Calculator and the Tank Sizing Guide; the 2500 gallon vertical storage tank buyer's guide covers siting in more detail.
The mistake to avoid
The most overlooked failure point on a vertical HDPE tank of this height is the vapor-saturated headspace above the liquid line, where the wall is thinnest and premature failures tend to originate - a liquid-side inspection alone will miss it. If the tank goes into a private fire-protection or rural reservoir role, size and protect it deliberately: see HDPE tank wall thickness at the vapor-saturated headspace and the fire-water reservoir tank design guide. One more honest note: fitting sizes and positions are not listed in our spec data for this tank - confirm the inlet, outlet, and lid against the technical drawing on this page before you plumb anything in, and if you take advantage of the 1.9 rating for a heavier liquid, confirm your fitting and gasket materials suit that service first.
Freight
This Norwesco vertical tank ships by LTL freight from the nearest Norwesco plant - Hanford, CA or Merced, CA - with the rate quoted live to your ZIP code. At roughly 20,850 pounds of water weight when full it is a freight-class load, so get your number up front with the Freight Cost Estimator, or call 866-418-1777 and we will quote it for you. Listed price is before freight; freight is quoted separately to your ZIP.
