The Norwesco 3000 Gallon HDPE Vertical Liquid Storage Tank (SKU N-43138) is a 102-inch-diameter, 93-inch-tall polyethylene vertical tank built for bulk water and liquid storage where footprint matters more than height. At 8.5 feet across and just under 8 feet tall, it holds 3,000 gallons in a stable, low-profile cylinder that suits rural water supply, irrigation feed, fire-water reserve, and general process storage. This is a Norwesco vertical storage tank, and the spec line below is the short version of what you need before you buy.
Will it work for your site?
The numbers that decide your install, straight from the spec sheet: full of water this tank weighs 25,020 lb, and at its 1.9 specific gravity rating — the densest legal fill — the maximum rated contents weight is 47,538 lb. That 1.9 rating means the polyethylene wall is engineered to hold liquids up to 1.9 times the density of water, so for plain water (SG 1.0) you sit well inside the wall rating with comfortable margin. Before delivery, pour or compact a level pad of at least 102 in (8.5 ft) diameter rated for the full 25,020 lb water weight — size the base for the loaded tank, never the empty one. Confirm your liquid's specific gravity against that 1.9 number before filling, and use the Tank Sizing Calculator and Tank Sizing Guide to match capacity, weight, and pad loading to your actual draw.
Fittings and how it ships
This Norwesco vertical ships with a standard lid and threaded outlet, but the exact outlet size, fitting layout, and gasket material are confirmed by the technical drawing on this page and verified at quote before your order goes in — so spec them rather than assume them. The tank itself is manufactured in California and ships LTL freight from the nearest Norwesco plant to you, Hanford, CA or Merced, CA. Freight is quoted live to your ZIP code rather than rolled into the list price, because a 102-inch-diameter tank moves as oversized LTL and the rate depends entirely on distance and destination. Run your ZIP through the Freight Cost Estimator for a real number, or call 866-418-1777 and we will quote it for you.
The mistake to avoid
The most common error on a tank this size is under-building the foundation. A 3,000-gallon vertical applies its full 25,020 lb of water weight straight down through the base; an undersized, unlevel, or poorly compacted pad leads to uneven loading and stress on the polyethylene floor. The second mistake is reading the 1.9 SG rating as a chemical clearance — it sets the density limit, not chemical compatibility. For anything other than water, verify both the polyethylene wall and the gasket and fitting elastomer against your specific liquid before filling; the density rating and the material compatibility are two separate checks. If you are weighing this 3000-gallon size against neighboring options, compare the 1.9 SG rating on this unit against the lighter-duty 3000-gallon 102 x 93 natural-white builds in the buyer's guides linked on this page — if you are storing something denser than water, the heavier-wall 1.9 SG version is the one you want.
