This is the green, California-only build of Norwesco's 550 gallon vertical water storage tank, and it ships from Norwesco's Hanford, CA plant. If you are ordering outside California, call 866-418-1777 before you go further so we can route you to the correct out-of-state build and avoid a freight or fulfillment block. For California water storage installs, this is a workhorse vertical: 550 gallons in a squat 67-inch diameter footprint that stands just 44 inches tall, which makes it a stable choice where overhead clearance is tight but ground space is available.
Will this tank work for your job?
This is a polyethylene vertical water tank with a 1.0 specific gravity rating, meaning it is built for water and water-density liquids only. Filled, it carries 4,587 pounds, which is also its maximum rated contents weight - that loaded figure, not the empty shell, is the number to design your pad and base support around. The footprint is 67 x 67 inches with a 44-inch overall height, so plan a level, continuous foundation under the entire base plus overhead access at the top for the fill and lid. See the technical drawing on this page for the dimensional layout before you pour a pad or frame a stand. If you are not sure this capacity matches your draw-and-refill cycle, run it through our Tank Sizing Calculator and the Tank Sizing Guide first.
The mistake to avoid
The 1.0 specific gravity rating is the constraint to respect. This tank is engineered for water and similar water-weight liquids - it is not rated to safely hold anything denser. Heavier liquids load the wall beyond what it was built for, so keep this unit on water service; if you need to store something heavier than water, call 866-418-1777 and we will get you a correctly rated tank instead. The second common miss is the foundation: at 4,587 pounds full, a soft or uneven pad lets the base flex and settle. A flat, continuous concrete pad sized for the loaded weight is the right approach, and our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting it right.
Fittings and putting it to work
Fitting configuration on this tank - lid, inlet, outlet, and any bulkhead placement - follows the manufacturer drawing and is confirmed at order, so check the technical drawing on this page and call 866-418-1777 if you need a specific outlet size or position verified before you buy. This vertical storage tank is a common pick for rural and remote water storage, including private fire-protection reservoirs where a buffered volume of water matters more than mains pressure; our write-up on fire-water reservoir tank design for rural sites covers NFPA 22 sizing discipline and freeze protection for cold-climate service. It also fits grey-water, rainwater, and HVAC condensate aggregation in water-reuse trains, detailed in our industrial water reuse tank topology guide. Once the tank is set, fill and prove it before you rely on it - our hydrostatic test methodology guide covers water-fill acceptance, pad-settlement monitoring, and hold-time math.
