Horizontal Leg Tanks are for storage and are not to be pressurized.
Space-efficient and reliable, this 125 gallon water storage tank provides an ideal solution for homeowners and businesses requiring dependable water reserves without excessive footprint demands. The horizontal leg design ensures stability on various surfaces while the tan coloring naturally blends into outdoor environments, making it less obtrusive than other storage options.
This 125 gallon horizonal tank for water storage excels in residential applications such as emergency preparedness, irrigation system supplementation, and livestock watering stations. The rotational molding process creates a seamless, one-piece construction that eliminates weak points where leaks commonly develop in welded or seamed alternatives. With a maximum operating temperature of 140°F, this tank accommodates both cold and moderately warm water storage needs throughout changing seasons.
The 8-inch threaded lid provides convenient access for filling, cleaning, and adding accessories like float valves or filtration systems. At just 52 pounds when empty, this 125 gallon tank for water storage remains manageable for repositioning as your storage requirements evolve. The compact dimensions of 45.5 inches in length allow placement in tight spaces such as alongside buildings, under decks, or in utility areas where vertical water storage tanks might not fit.
Installation Advantages and Site FlexibilityUnlike permanent installations, this portable 125 gallon water tank gives you the freedom to relocate your water supply as landscaping changes or new structures are added to your property. The four sturdy legs distribute weight evenly, reducing ground pressure and minimizing settlement issues on softer soils. This feature proves particularly valuable for seasonal applications where temporary water access is needed for gardens, construction sites, or outdoor events.
The UV-resistant polyethylene construction maintains structural integrity despite continuous sun exposure, preventing the brittleness and cracking that plague inferior materials. This protection extends the service life of your investment while maintaining water quality by preventing sunlight from promoting algae growth inside the tank. The 1.2 specific gravity rating ensures compatibility with standard municipal water, well water, and rainwater harvesting systems.

Frequently Asked Questions
What's the difference between this horizontal tank and vertical models?
Horizontal designs like this 125 gallon poly tank for water storage offer a lower center of gravity for improved stability in windy or uneven conditions. They are also easier to conceal and fit into areas with height restrictions such as crawl spaces or beneath overhangs.
Can this tank handle freeze-thaw cycles?
Polyethylene demonstrates excellent flexibility during temperature fluctuations. However, we recommend draining the tank before sustained freezing temperatures to prevent ice expansion damage. For year-round use in cold climates, consider insulation or heated bases.
How do I connect plumbing to this 125 gallon water tank?
The tank accepts standard bulkhead fittings that can be installed through the sidewall for gravity-fed systems. Many users add a spigot near the base for convenient hose connections, while others integrate float valves for automatic filling applications.
Is this suitable for potable water storage?
The food-grade polyethylene material is safe for drinking water storage. Always use water from approved sources and follow local regulations regarding potable water storage, including regular cleaning and proper sealing to maintain water quality.
