    Vertical Water Storage Tanks

    UV-Resistant Vertical Plastic Tanks for Water and Chemical Storage

    A vertical water tank stores more in less floor space by building upward instead of outward, so it fits tight yards, corners, and indoor rooms while giving you gravity-fed pressure at the outlet. Our vertical water storage tanks are molded from UV-stabilized polyethylene for long, low-maintenance service outdoors, in a wide range of capacities for potable and non-potable water. Compare flat-bottom, cone-bottom, and open-top styles below, or step up to the full large water storage tanks hub to weigh every form and material.

    When to Choose a Vertical Water Tank

    Vertical and horizontal tanks hold the same water in very different shapes. A vertical water tank stands upright on a compact base, so it fits tight yards, corners, and indoor rooms, and its height builds pressure for gravity-fed lines. A horizontal tank lies low and wide, which suits transport, low-clearance spaces, and installs where a stable, spread-out base matters more than floor space. If you are weighing the two, our horizontal tanks page covers the flat side of that decision.

    • Tight footprint: you have limited floor space but room to build upward.
    • Gravity feed: you want pressure at the outlet without adding a pump.
    • Steady storage: the tank sits on a fixed, level pad for the long term.

    Vertical tanks also come in different bottoms. Flat-bottom tanks sit directly on a level pad for steady, long-term storage, while cone-bottom tanks slope to a center outlet so they drain completely, which is ideal for mixing and batching. If full drainage matters for your process, see our cone-bottom tanks.

    Vertical Water Tank Styles: Flat, Cone, and Open-Top

    Three vertical tank styles, and what each one is built for.
    Tank styleBest forBottom and drainage
    Flat-bottom tanks Steady, long-term storage on a level pad Flat base sits directly on the ground, drains through a side or bottom fitting
    Cone-bottom tanks Mixing and batching that must empty completely Sloped cone drains to a center outlet for full drainage, needs a stand
    Open-top tanks Easy filling, hand mixing, and access from above Open lid with straight or tapered walls, drains through a bottom fitting

    All three styles are molded from UV-stabilized polyethylene in a wide range of capacities. Exact dimensions, gallons, and fittings are listed on each product page.

    Features and Benefits

    Built to Last, Sized to Fit

    • UV-stabilized polyethyleneShrugs off sun and weather, so the tank holds up outdoors for years without cracking or fading.
    • Seamless one-piece moldingNo seams or joints to fail, which keeps it leak-resistant over a long service life.
    • Upright, small-footprint designFits tight yards, corners, and indoor rooms, freeing up ground space for other work.
    • Elevated outlet heightBuilds gravity-fed pressure at the tap, often without adding a pump.
    • Rust-free and corrosion-freeUnlike steel, poly will not rust, so upkeep stays low year after year.
    • Range of capacities and fittingsMatch the tank to your volume and connect it to your existing plumbing.

    Where Vertical Water Tanks Are Used

    Because they store a lot in a small footprint, vertical water tanks show up anywhere space is limited and reliable storage matters.

    • Homes and cabins: main or backup water supply where floor space is limited.
    • Farms and ranches: livestock water, sprayer fill, and irrigation supply.
    • Commercial and industrial: process water, washdown, and buffer storage between deliveries.
    • Rainwater collection: upright storage that captures roof runoff in a small footprint.
    • Emergency and off-grid: stored water for outages, fire protection, and remote sites.

    How to Choose a Vertical Water Tank

    Picking the right tank comes down to capacity, the space you have, and how you will connect it.

    • Capacity: size from your daily use and how many days of reserve you want. If you are unsure, our water tank sizing guide walks through the math.
    • Footprint and height: measure the pad and any clearance, like doorways or ceilings, before you commit to an upright profile.
    • Bottom style: choose flat for steady storage or cone for full drainage, using the comparison above.
    • Water use: confirm the tank is rated for potable water if you need drinking water, otherwise it works well for irrigation and washdown.
    • Fittings: match the inlet and outlet size and placement to your plumbing so the install stays simple.

    Vertical Water Tank FAQs

    When should I choose a vertical tank over horizontal?

    Choose a vertical tank when floor space is tight or you want gravity-fed pressure, since it stands upright on a small base and its height builds head at the outlet. Choose a horizontal tank when you need a low, stable profile for transport or low-clearance installs. Both hold water equally well, so the decision comes down to your space and how you feed the line.

    What capacities do vertical tanks come in?

    Vertical water tanks come in a wide range of capacities, from small tanks for homes and yards up to large upright storage for farms and commercial sites. The exact gallons available depend on the model, so check each product page for its capacity. Size yours from your daily demand and how often the tank refills.

    Can vertical tanks store potable water?

    Many vertical poly tanks are suitable for potable water, but it depends on the specific tank and its material rating. Look for a tank marked safe for drinking water, and confirm the rating on the product page or with a specialist before use. Tanks not rated for potable water still work well for irrigation, washdown, and other non-potable uses.
