The Norwesco 600 Gallon Dark Brown Vertical Water Storage Tank is a polyethylene tank built for bulk water storage. It holds 600 gallons on a 64 by 64 inch base, so it concentrates real volume onto a compact, square footprint that fits equipment yards, pump houses, and rural sites without sprawling across the pad. The dark brown color reduces light transmission into the tank, which limits the photosynthetic light that algae need in stored water and helps the tank blend into residential and farm settings. Before you order, confirm the height, base diameter, fitting locations, and outlet position against the technical drawing on this page, so the real envelope matches your space and plumbing.
Will this tank work for my application?
This is a 600-gallon vertical water storage tank rated for a specific gravity of 1.0, which means it is sized for water and water-weight liquids. Filled to capacity it carries 5,004 pounds, and that full-water weight is also the maximum rated contents weight for the tank. Use that number when you plan support and when you size the slab. For a quick check on whether 600 gallons matches your draw and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. The tank's fitting and outlet details, including bulkhead size and location, are documented on the technical drawing on this page; match the outlet size, fitting thread, and gasket material to your plumbing from that drawing before you order, since those details determine whether your existing connections drop straight in.
Siting and pad load
A loaded water tank puts its full weight on the base, so the pad matters. Spread across the 64 by 64 inch footprint, 5,004 pounds works out to roughly 176 pounds per square foot of average distributed load before any edge or dynamic concentration, which is the starting number a slab designer needs. Above-ground polyethylene tanks like this one want a continuous, level, properly sized concrete pad rather than blocking or partial support; 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. Once the tank is set, fill it with water and watch for pad settlement and fitting leaks before service; the hydrostatic test methodology for new-install acceptance covers water-fill discipline and hold-time math so you commission the tank correctly the first time.
The mistake to avoid
This tank is rated to a specific gravity of 1.0, and that rating is the trap. A 1.0 SG tank is built for the weight of water, so do not press it into service for liquids heavier than water, such as fertilizers, brines, or chemical solutions with a higher specific gravity, without moving up to a tank rated for that density. If your liquid is heavier than water, ask us for a 1.5 or 1.9 SG-rated vertical instead, or call 866-418-1777 and we will point you to the right-rated equivalent. For rainwater harvest, fire-reserve, and process-water duty this tank is a strong fit. If you are sizing a private fire-protection reservoir, our write-up on fire-water reservoir tank design covers NFPA 22 sizing discipline and cold-climate freeze protection, and if you are aggregating grey water, rainwater, or HVAC condensate, the industrial water reuse tank topology guide maps quality-banded storage trains.
