Bushman 100 Gallon Plastic Vertical Liquid Storage Tank in Black

The Bushman 100 Gallon Plastic Vertical Liquid Storage Tank in black is a compact, freestanding polyethylene water tank built for tight footprints. At 30" diameter and 42" tall, it holds 100 gallons inside a 30.0 x 30.0 inch footprint, so it fits along a wall, in a utility closet, on a trailer, or in a pump house where a wider tank will not go. The black resin blocks sunlight, which slows algae growth in stored water - a practical advantage over translucent tanks for any outdoor or semi-shaded installation.

Will it work for your application?

This is a vertical water storage tank rated to a specific gravity of 1.0, meaning it is engineered to hold water-weight liquids. Filled to capacity, 100 gallons of water weighs about 834 lbs, which is also the maximum rated contents weight - plan your pad, stand, or floor for that load before you fill it. A full vertical tank needs a level, fully supported base; never set a loaded tank on an uneven or partially supported surface. Two fittings come on the tank: a Ø2" FNPT spin-weld outlet in polyethylene low on the wall for draining or plumbing to a pump, and a Ø10" OD / Ø8" ID twist-lid assembly on top giving roughly 8" of clear access for filling, inspection, and venting. The outlet is female NPT, so bring a 2" male NPT nipple or bulkhead and seal the tapered threads with PTFE tape - or use a poly/EPDM bulkhead gasket kit if you are running a through-wall connection rather than threading directly. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 100 gallons matches your draw-down and refill cycle. Exact dimensions and fitting placement are detailed on the technical drawing on this page.

Common uses and sizing

Buyers reach for a 100 gallon vertical storage tank for rainwater capture, pump-fed irrigation, livestock and garden water, and emergency or backup supply. If you are sizing for rainwater harvesting, the Bushman first-flush diverter sizing guide walks through the capture math. For rural fire-protection reservoirs, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection. Comparing colors or capacities? The 100 gallon vertical tank buyer's guide lays out the trade-offs against the natural-white version.

The mistake to avoid

This tank is rated to a specific gravity of 1.0 - water-weight liquids only. The decision rule is simple: if your liquid is heavier than water, this is the wrong tank. Anything denser than water can overload the wall thickness this tank was designed for, so step up to a tank rated SG 1.5 or 1.9 for heavier-than-water contents and reserve this one for water and water-weight liquids. Match the liquid's specific gravity to the 1.0 rating and the tank will serve a long life. The second common error is on the outlet: confirm you have the right thread gender (the port is female NPT) and do not assume the top opening is a full manway - it is an 8" ID twist lid, not a wide-mouth access.

This tank ships LTL freight from Fairfield, TX, and freight is quoted live to your ZIP code. Empty shipping weight is low and the tank moves as a single 30 x 30 pallet, so liftgate or limited-access delivery is usually the main cost driver rather than weight - get an exact number with our Freight Cost Estimator or call 866-418-1777. Run the estimator before you order so the freight cost is in front of you, and our team can confirm liftgate or limited-access service if your site needs it.
