The Norwesco 1075 Gallon Dark Green Vertical Water Storage Tank is a polyethylene vertical tank built for bulk water storage on farms, rural homesteads, fire-water reservoirs, and remote sites. It holds 1,075 gallons inside an 87-inch diameter, 51-inch tall body, so it stores serious volume while staying low and stable. The dark green color cuts light penetration to slow algae growth in outdoor service, and the wide footprint keeps a full tank planted instead of top-heavy.
Will it work for my site?
Footprint is the first thing to check: this tank stands on an 87.0 x 87.0 inch base — a full 87-inch diameter circle — so measure your pad before ordering. Filled with water it carries 8,966 pounds, which is also its maximum rated contents weight at the 1.0 specific gravity this tank is built for, and all of that load lands on that 87-inch circle. Under-built pads are the most common install mistake on a tank this size, so the pad has to carry the loaded weight and the ground under the pad has to carry the pad. If you are sizing a pour, our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground poly tanks. Not sure 1,075 gallons fits your draw and refill cycle? Run the numbers in the Tank Sizing Calculator or read the Tank Sizing Guide first. See the technical drawing on this page for the full dimensional layout.
Specs and fittings
Capacity is 1,075 gallons. Diameter is 87 inches, overall height is 51 inches, and the material is polyethylene rated for contents up to a specific gravity of 1.0 — built for water and water-weight liquids, not heavier chemicals. This is a vertical water storage tank in the classic Norwesco vertical tank form, sized for water storage and vertical storage tank duty wherever a stable, large-volume reservoir is needed. Fittings (outlet size, lid, and any inlet or overflow) are confirmed by phone before the tank ships — call 866-418-1777 and we will verify the exact configuration, the gasket material at any bulkhead or outlet connection, and the outlet thread so your plumbing tie-in matches before it leaves the dock.
The mistake to avoid
This tank is rated to a 1.0 specific gravity, the density of water. Do not put a liquid heavier than water in it — most fertilizers, brines, and chemical concentrates exceed 1.0 and would overload the wall this tank was designed for. Keep it on water-weight service. If you need fertilizer, brine, or chemical storage above 1.0 SG, this water tank is not the right tank; call 866-418-1777 and we will match you to a higher-SG-rated tank instead. If your plan is fire-water reservoir storage, read our fire-water reservoir design guide for NFPA 22 sizing and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the water reuse topology guide covers quality-banded storage trains. Before you put it into service, the hydrostatic test methodology guide covers the water-fill acceptance check that catches pad settlement and fitting leaks before they cost you.
