The Norwesco 3000 Gallon Plastic Water Storage Tank in black (SKU N-42960) is a vertical polyethylene tank that measures 98" in diameter and 101" tall, built for bulk water storage where you need real volume without spreading across the yard. The black wall suits outdoor water supply, irrigation, and rainwater or reuse storage. Below you will find what it holds, how it ships from Texas, and the one number people forget to plan for.
Specifications and how this tank performs
This is a vertical water storage tank with a 3000-gallon capacity, a 98" x 98" footprint, and an overall height of 101". The wall is polyethylene with a specific gravity rating of 1.1, which means it is engineered to safely hold contents up to 1.1 times the weight of water. Plain water is SG 1.0, so at the 1.1 rating you have a built-in margin for cold or dense water and incidental solids. One honest caution: if you are storing anything heavier than water - fertilizer, brine, or a chemical - this 1.1-rated tank is not the right pick. Use the Tank Sizing Guide or call 866-418-1777 and we will point you to a higher-SG-rated tank. If you are comparing this against other vertical storage tank sizes, run your volume and weight through the Tank Sizing Calculator before you commit to a pad.
Site prep and the mistake to avoid
The number people forget is the full water weight. Empty, the shell is light enough for a few people to position; filled with water it carries roughly 25,020 lb, and the structure is rated to a maximum contents weight of 27,522 lb. Size the pad and any tie-downs for the full loaded weight, not the empty shell, and never fill before the base is complete. A tank this size needs a level, fully supporting base across the entire 98" x 98" footprint - compacted base material or a properly sized concrete pad, not a partial ring or uneven ground. Polyethylene tanks transfer their load straight to whatever sits directly beneath them, so any gap or soft spot becomes a stress point. For outlet and fitting sizes and positions, see the technical drawing on this page; we don't list them in the spec table for this SKU, so verify the drawing or call us before you order plumbing. For remote-site reservoir planning, our guide on fire-water reservoir tank design walks through NFPA 22 sizing discipline and cold-climate freeze protection, and the industrial water reuse topology guide covers grey-water, rainwater, and condensate aggregation.
Freight and how it ships
This 3000-gallon tank ships LTL freight from the Norwesco plant in Petersburg, Texas, with the rate quoted live to your ZIP code. Because it is a 98" x 101" non-stackable load, the freight cost is distance-driven, so get your exact number with the Freight Cost Estimator before you compare prices, or call 866-418-1777 and we will work the freight with you. For a deeper look at this exact model, see the complete buyer's guide for this 98" x 101" tank. If you need a shorter, wider profile for the same 3000 gallons, the companion guide for the 102" x 93" tank covers that separate SKU - check the footprint before you order so you set the right one.
