The 4995 Gallon Vertical Liquid Storage Tank from Norwesco is a polyethylene bulk-storage vessel built for high-volume water and liquid duty where ground footprint matters more than spread-out capacity. It stands 142 inches tall on an 89-inch-diameter base, putting nearly 5,000 gallons of usable storage into a single vertical column. It ships LTL from the Norwesco plant in Fairfield, TX, with freight quoted live to your ZIP. With a 1.5 specific gravity rating, this is one of the heavier-duty vertical tanks in the lineup, and that rating is the first thing to understand before you fill it.
Will it work for your site?
At full water capacity, this tank holds 41,658 pounds of water, and its maximum rated contents weight runs all the way up to 62,487 pounds at the 1.5 specific gravity ceiling. That spread tells you two things. First, the 89-inch-diameter footprint has to carry a heavy, concentrated load, so a properly engineered base is not optional at this size. Second, you have real headroom to store liquids denser than water without exceeding the tank's structural rating. If you are sizing a reservoir for fire-water standby, irrigation supply, or process water, run your numbers through the Tank Sizing Calculator, review the Tank Sizing Guide, and go deeper on this exact model with the 4995 Gallon Vertical Liquid Storage Tank complete buyer's guide to confirm the working volume matches your draw and refill cycle. For fitting locations and overall geometry, see the technical drawing on this page; the standard fitting configuration (fill, outlet, vent, and manway) is confirmed at quote, so call 866-418-1777 for the exact bulkhead sizes for your plumbing.
Foundation and freight planning
A vertical storage tank this tall and this heavy demands a flat, level, fully supporting pad. Plan your pad for the full 89-inch-diameter footprint, because a loaded weight north of 41,000 pounds on that bearing circle generates serious pressure, making the pad a design decision rather than an afterthought. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies, so your foundation matches the rated contents weight rather than guesswork.
Common applications
This Norwesco vertical tank is a frequent pick for rural and remote fire-water reservoirs, industrial water reuse trains, and standby bulk storage. If fire protection is your use case, our write-up on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and freeze-protection engineering for cold-climate service. For reclaimed and blended water programs, our piece on industrial water reuse tank topology maps out grey-water, rainwater, and HVAC condensate aggregation.
The mistake to avoid
The most common error at this size is treating the 4995-gallon water number and the 62,487-pound maximum contents number as the same thing. They are not. Water fills this tank to 41,658 pounds; the higher figure exists because the 1.5 specific gravity rating allows denser liquids, but it does not mean you can add more volume. If your liquid is heavier than water, size your pad and supports to the rated contents weight, not the water weight, and confirm chemical compatibility and gasket or seal selection for that fluid before filling, so the 1.5 ceiling is matched by the right materials end to end.
