A 4000 gallon black crosslinked tank for water, fertilizer and light process liquids
Snyder part number 7421100N46 is a 4000 gallon vertical storage tank in black crosslinked linear polyethylene, 120 inches in diameter, 100 inches tall and 810 lb empty. It is the standard wall version of the 7421100 tank, rated for liquids up to 1.5 specific gravity, which is up to 1.5 times the weight of water. Four thousand gallons of water weighs 33,360 lb (4000 x 8.34). The top opening is an 18 inch threaded vented manway. Snyder puts the service limit at 140 F (60 C) and backs it with a 3 year warranty. The black wall blocks light, which slows algae in stored water and protects light sensitive liquids.

Where this shape earns its floor space
This is the wide and short way to hold 4000 gallons: ten feet across and 100 inches to the top. It goes under a low roof, a loft or an awning where a taller tank will not, the fill line and vent land comfortably above the opening, and a short step ladder reaches the manway. In exchange it takes a ten foot circle of level floor, and that circle does not pass a normal doorway, so measure the route in before you order. The 1.5 rating covers water, rainwater, most liquid fertilizers and the common farm and treatment liquids that polyethylene handles. If the liquid is denser than 1.5 times water, a brine or a concentrate, step up to the black heavy duty 7421100N48, rated 1.9, rather than running this one near its limit. Crosslinked polyethylene gives you more margin on chemistry than ordinary polyethylene; check anything beyond water and fertilizer in our chemical compatibility guide before the first fill.
Full of water the tank puts 33,360 lb on the pad, spread over the whole floor. The slab has to be level and in complete contact; a low corner carries the weight alone and the wall finds it early. Our concrete pad sizing guide gives the method. Do not plan on filling to the rim: leave freeboard for thermal expansion and sloshing, and read our note on freeboard sizing and the real volume you can actually use when you size the order. Run the volume through the tank sizing calculator and the tank sizing guide. For a rural fire water reserve, the fire water reservoir design guide covers sizing and freeze protection.
Openings and what to confirm before you buy
- Manway. 18 inch, threaded and vented, on top. Land the fill line here with a dip tube to the floor so a fill does not free fall and aerate the load, and size the vent to the truck's pump.
- Outlet. The listing does not state an installed outlet. Tell us the drain size and material you want and we will confirm with Snyder what the tank ships with.
- Temperature. 140 F (60 C) service limit. Fine for ambient storage; ask before putting a hot process stream in it.
- Drawing. Snyder's drawing is linked on this page under Technical Drawing, with the profile and fitting positions for your layout.
The other 7421100 versions and the neighbours

The natural white standard version, so you can see the level through the wall, is the standard 7421100N40, and there is also the heavy duty 7421100N42. Close in volume: the 3900 gallon 5190000N40 and, one step up, the 4100 gallon black heavy duty 7360000C34; compare their diameter and height on their own pages.
