Snyder Industries 1000 Gallon Black Vertical Water Storage Tank

Four tons of water under a low eave

Full, the WB41R puts 8,340 pounds on a 72 inch circle, and a rotationally molded floor bears on the whole pad, so the pad is what matters: a compacted, screeded gravel base or a slab in full contact; at 65 inches it sits low enough that no strap is needed. Black polyethylene absorbs the ultraviolet that ages a white wall and passes no light to the liquid, so a black tank outdoors holds water clear for years; it also runs warmer than a white one, which matters for water in a hot climate. Our 1,000 gallon black water tank buyers guide compares the shapes at this volume across makers; the tank sizing calculator tells you whether 1,000 gallons covers the draw, and the tank sizing guide covers days of supply.

Snyder's 750 to 1,100 gallon water tanks

The WG41R is the same low tank in green, heavier in the wall, for a site where green hides better than black. The 32523 and 32525 stand the same 1,000 gallons on a 60 inch base at 89 inches for a corner with height and no floor, the WB42 lays 1,100 gallons of black down even lower on an 86 inch base, and the 32517 is the 750 gallon doorway tank.

The three openings

• Inlet: 1-1/2 inch polypropylene female NPT bulkhead fitting.
• Outlet: 2 inch polypropylene bolted fitting with stainless hardware, at the base; a flexible connector between the fitting and hard pipe, and the valve supported off the pad.
• Access: 18 inch threaded, vented manway, reached from a step.
• Service limit: 120 F / 48 C.

A bolted outlet spreads the load of a valve and pipe run over a ring rather than a thread, which is welcome on a tank that gets plumbed hard. A 2 inch outlet on a low tank gives a pressure pump a flooded suction to the last few inches; a garden hose runs by gravity but slowly, because there is little head. A black wall shows no level, so fit a float gauge on the manway or a sight tube off the outlet, and a float switch at low level shuts the pump off before it runs dry. If winters freeze, wrap or drain the outlet valve and the first pipe run; the body takes ice from the top down without harm.

Where we ship it

Well storage for a house and a garden under a low eave, a rain cistern beside a barn, stock water on a pasture, a haul-in water supply for a cabin, and one cell of a small fire reserve of the kind the fire-water reservoir design guide describes. Several of them are the storage stage of a reuse system for roof water and condensate, per the industrial water reuse tank topology article, where the dark wall keeps the stored water clear.

How it ships

The WB41R ships as LTL freight at class 400, the class light, bulky tanks take; the freight cost estimator shows it for your ZIP, and the listed price is before freight. Two people carry 160 pounds, and at 72 inches across it goes through a double door or a gate. Fill it to the manway once, check both fittings, and set it where the outlet faces the pump, because a low tank is not easily turned once it is full. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
