The Norwesco 950 Gallon Black Vertical Storage Tank (SKU 44818B) is a 134-inch-tall polyethylene tank built on a compact 48-by-48-inch footprint, so you get close to a thousand gallons of bulk water capacity without sprawling across your pad. The black, opaque polyethylene inhibits algae growth by keeping light out of the stored water, and the 1.5 specific gravity rating gives this Norwesco vertical tank the structural margin to hold contents denser than water, not just water alone. If you have been searching for a black vertical storage tank that holds nearly a thousand gallons in a tight ground footprint, this is the size that fits.
Will it work for your site?
Full of water, this tank carries roughly 7,923 pounds, and at its maximum 1.5 specific gravity rating it is engineered for contents up to 11,884 pounds. The tank shell itself is light enough to set by hand or strap into position before it sees any liquid, but that weight delta carries an install rule: fill it in place on its final pad. Once water is in it, you are not moving it. Plan your foundation around the loaded numbers, with a level, full-contact base rated for the full weight so the entire 48-by-48-inch footprint bears evenly. To confirm this is the right capacity for your draw and refill cycle, run the Tank Sizing Calculator or read the Tank Sizing Guide. The technical drawing on this page shows the overall dimensions for your install planning.
The mistake to avoid
The most common error with a vertical storage tank this size is the foundation. At 134 inches tall, this is a top-heavy column when full, and any slope, void, or soft spot under the base concentrates stress on the floor knuckle. Pour or set a pad that supports the full 48-by-48-inch footprint with no overhang and no high points. If you are sizing a concrete pad, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 approach for this exact scenario. Read the 1.5 specific gravity ceiling correctly, too: it is the heaviest contents the wall is rated for. Because it sits at the highest standard tier, this tank already covers many heavier-than-water liquids up to 11,884 pounds of contents, so a buyer storing dense fluids does not need to step up to a specialty vessel. Just do not assume any single liquid clears without checking its specific gravity against that 1.5 rating.
Fittings and where it fits in a water system
Outlet and fitting layout varies by tank and is not listed for this unit, so confirm the bulkhead fitting size and gasket configuration by phone at 866-418-1777 before you order and plumb it to your system. At 950 gallons this tank works as a fire-water reserve, a rainwater or grey-water aggregation vessel, or general bulk water storage. For rural fire protection sizing, our guide on fire-water reservoir tank design covers NFPA 22 discipline and cold-climate freeze protection. If you are building a reuse train, the industrial water reuse tank topology guide shows how a tank this size sequences into grey-water and rainwater storage stages.
