These galvanised steel water tanks are ideal for farms, construction sites, and industrial operations. They resist harsh weather and rough conditions. Choose above-ground or underground models, each crafted for durability and long-term performance. When reliability matters most, steel is the smart choice.

Corrugated Steel Water Tanks

Corrugated Steel Water Tanks are our largest available water storage option, with capacities of up to 600,000 gallons. These tanks save on the delivery cost because they ship at only a fraction of their installed size, thanks to the sections of corrugated steel.

Once on-site, corrugated steel bulk storage tanks can be quickly installed, making them an ideal choice for farming, industrial use, or emergency water supply. They’re great for things like irrigation, rainwater collection, or holding process water. If you need bulk storage fast, and you don’t want the hassle of heavy freight, these are a great fit.

Fiberglass Tanks

Fiberglass storage tanks provide a reliable solution for liquid storage in agricultural facilities, residential properties, and commercial locations. This is safe for water storage, waste storage, and chemicals storage.

Fiberglass tanks are built to handle water, waste, or chemicals without corroding or denting. That makes them perfect for places where metal tanks might wear down, like coastal areas, farms, or underground installs. Fiberglass tanks come in various models, including above-ground dome-style tanks, underground storage tanks, and flat-top fiberglass basins.

Plastic Water Tanks

The vertical poly water tanks offer a reliable solution for outdoor water storage that specifically designed to protect your drinking water. With a dark black or green color tank, it effectively blocks sunlight, reducing algae growth and ensuring cleaner water. Constructed from FDA-approved materials, our poly tanks meet standards for potable drinking water storage. These tanks provide a durable and cost-effective option for long-term water storage needs.

Flexible Water Bladder Tanks for Temporary Liquid Storage

The flexible large-capacity water tanks, also known as pillow tanks or water bladders, are ideal for temporarily storing substantial amounts of liquid at your site. Designed to hold up to 210,000 gallons, these USA-made water bladder tanks are perfect for use during tank repairs, temporary work projects, or hydraulic fracturing (fracking). Constructed from high-quality fabrics, they are suitable for storing potable water, brine water, process/production water, fracking liquids, and even diesel fuel.

Onion Water Tanks

Onion tanks, also known as pumpkin tanks, are flexible, open-top storage solutions designed for potable and non-potable water storage. Ideal for locations that require temporary liquid storage, these self-rising onion tanks are easy to store and deploy quickly. With their fast setup and easy filling capabilities, they are perfect for firefighting, military operations, emergency relief, and more. Choose our high-quality onion tanks for dependable, convenient temporary water storage.

Why Choose a Large Water Tank

• Multiple materials, one source: galvanized and corrugated steel, fiberglass, poly, and flexible fabric, so the tank matches the job instead of the other way around.
• Capacity that scales: options run from a few hundred gallons up to bulk-volume builds. For the biggest jobs, see our bulk water storage tanks.
• Above-ground or underground: place the tank where the site allows, including underground options where footprint or freeze protection is a concern.
• Vertical or horizontal builds: space-saving formats including vertical water storage tanks for tight footprints.
• Configurable fittings and outlets for potable, process, and non-potable water service.

Common Large Water Tank Applications

Large-volume storage shows up wherever a site needs more water than the municipal line can deliver on demand, or needs to hold non-potable liquids on hand. The right material and capacity depend on what is stored and where.

• Agriculture and irrigation: crop watering, livestock supply, and on-farm reserve storage.
• Construction and site work: dust control, soil compaction, and concrete and equipment washdown.
• Municipal and rural water: potable supply, booster storage, and backup reserves.
• Industrial and process: process water, cooling, and grey water handling.
• Fire protection: on-site water supply for suppression and rural firefighting.
• Emergency and disaster relief: rapid-deploy temporary storage when infrastructure is down.
• Oil, gas, and energy: brine, process, and production water, plus frac fluid storage.
