The Norwesco 1550 Gallon Plastic Water Storage Tank (SKU N-40627) is a vertical polyethylene water tank measuring 87 inches in diameter and 67 inches tall, sized for bulk water storage where you need real volume on a compact footprint. At 1,550 gallons, it fits rainwater collection, irrigation reserves, livestock water, and fire-water reservoir duty at rural and remote sites. It is a water storage tank in the truest sense: a molded vertical storage tank rated for water and water-weight fluids, not for chemical service.
Will it hold up under a full load?
This tank carries a specific gravity rating of 1.0, which means it is engineered for fluids up to the weight of water. Filled completely, you are loading roughly 12,927 pounds of contents onto the base, and that figure is also the maximum rated contents weight. That ceiling is a buying constraint, not just a number: this tank is suitable for water and water-weight fluids only. Do not store liquids denser than water in it. Many fertilizers, brines, and chemicals exceed specific gravity 1.0 and require a higher-rated tank. If your fluid is heavier than water, this is the wrong tank. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 1,550 gallons matches your draw and refill cycle.
Planning the pad and the install
Because a vertical water tank this size transfers its entire load through the base, 12,927 pounds bearing on an 87-inch footprint demands a properly engineered, level pad. Plan for an 87-inch (7'-3'') diameter pad with working clearance around the full circumference for fill, vent, and outlet access; overall height is 67 in (5'-7''). A settled or out-of-level pad is the single most common install mistake at this scale, so size the foundation to the load first. Work through our concrete pad sizing framework before you set the tank, then prove it: our hydrostatic test methodology guide covers water-fill discipline, pad-settlement monitoring, and the hold-time math for new-install acceptance.
Fittings, application, and reuse service
Fitting configuration (bulkhead outlet, fill, and vent) is confirmed per order. See the technical drawing on this page for available bulkhead locations, and verify the bulkhead and gasket material is rated for your stored fluid before install. For fire-water reserve storage, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For greywater, rainwater, or HVAC condensate aggregation, our industrial water reuse topology guide walks through quality-banded storage trains and treatment-stage sequencing.
