The Norwesco 2100 Gallon Black Heavy Duty Vertical Storage Tank is built for serious bulk water storage where capacity and durability both matter. Listed at 2,100 gallons in a black polyethylene shell, it carries a 1.9 specific gravity rating - the heavy-duty designation - which means it is engineered to hold contents up to 1.9 times the weight of water without the wall thickness becoming the limiting factor. For straight water duty that gives you a wide safety margin, and the black resin adds UV resistance and algae suppression that the natural-translucent tanks do not provide. It ships from the nearest of nine nationwide Norwesco plants, so freight is not automatically a cross-country haul.
Will it work for your site?
The footprint is exactly 87 inches by 87 inches - a 7-foot-3 diameter - with an overall height of 89 inches, so plan your pad to that diameter and allow clearance for a hair over 7-foot-5 of overall height. Filled with water this tank carries about 17,514 pounds, and its 1.9 SG rating means it is structurally cleared for contents up to 33,277 pounds. That headroom is the real upsell: the same shell cross-serves as a heavy-fluid storage tank up to 1.9 specific gravity, so you can buy once and repurpose later. The full-water weight is the number that drives your foundation - a level, continuously supported pad is not optional at this size. If you are still deciding whether 2,100 gallons is the right volume, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit.
Foundation and application
At over 17,500 pounds full, this vertical storage tank demands a properly engineered base. Our walkthrough on concrete pad sizing for above-ground polyethylene tanks covers the ACI 360R-10 framework and where the ACI 318 boundary kicks in - read it before you pour. The 2,100-gallon black Norwesco is a common choice for rural fire-water reserves, agricultural supply, industrial process water, and rainwater or reuse storage. If fire protection is your application, our guide on fire-water reservoir tank design for rural and remote sites walks through NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and condensate aggregation, see our industrial water reuse tank topology breakdown.
The mistake to avoid
Fittings are not pre-configured on this listing - the 1.9 SG heavy-duty build is the same shell whether you run it as a water tank or a denser-fluid tank, so the fittings and outlet placement are what tailor it to your job and must be specified when you order. Before you buy, confirm two things against your service fluid: the outlet and bulkhead size you need, and the gasket material that suits it. Reference the technical drawing on this page for the dimensional layout, then call us at 866-418-1777 and we will lock in the fitting and gasket configuration for your installation.
