The Norwesco 1000 Gallon Black Vertical Storage Tank (SKU 44111B) is a 1000-gallon polyethylene vertical storage tank rated to 1.5 specific gravity, built for bulk water and high-density liquid storage where a tall, compact footprint matters. It stands 66 inches tall on a 72 x 72 inch base, so it holds a serious volume without spreading across your pad. The 1.5 SG shell is the spec that sets it apart from a standard 1.0/1.1-rated water tank: it carries heavier liquids a basic water tank cannot, and that headroom is the reason to choose this SKU. The black resin blocks sunlight, which limits algae growth in stored water far better than translucent or light-colored tanks.
Will it work for your job?
Plan around weight, not just gallons. Filled with plain water, this tank carries roughly 8,340 pounds of contents. Because the shell is rated to 1.5 specific gravity, you can store denser liquids up to a maximum rated contents weight of about 12,510 pounds, which is the ceiling the tank is built to handle. Those 8,340 to 12,510 pounds are the working range you are paying for. Use those numbers to size your foundation and to confirm the spot you have in mind can take the load. The 72 x 72 inch footprint should sit on a level, fully supporting pad with no overhang, no point loads, and no gaps under the base. To match gallons to your actual draw and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a size.
Fittings and fitment
This is a vertical storage tank, and its fitting layout (outlet, vent, and lid) is confirmed against the technical drawing on this page per order rather than pre-spec'd in a generic kit. Any outlet connection needs the matched bulkhead fitting and gasket sized to the drawing's port, not a hardware-store part that can leak or strip the threads. Review the technical drawing on this page for the exact dimensions, port locations, and base detail before you set the tank or plumb a connection, and call us if you want to confirm the right configuration for your install.
How it ships and the mistake to avoid
This SKU ships empty via LTL freight from the Norwesco plant in Hanford, CA. Because that is the single origin for this tank, East and Midwest buyers should pull a live ZIP quote before budgeting rather than assume a flat number. Freight is quoted live to your destination through the Freight Cost Estimator and is never folded into the list price. The most common mistake on a 1.5 specific-gravity tank is treating the gallon rating as the only limit. It is not. A 1000-gallon volume of a heavy liquid can hit the shell's weight ceiling long before the tank is physically full, which is why the 12,510-pound maximum rated contents figure exists. Match your liquid's specific gravity against that ceiling and pour a pad that carries the loaded weight. If you are designing storage for fire-water reserve, our guides on fire-water reservoir tank design and concrete pad sizing for above-ground polyethylene tanks walk through the engineering.
