Indoor and outdoor use
Horizontal Leg Tanks are for storage and are not to be pressurized.
The compact footprint of this 35-gallon horizontal tank makes it an excellent choice when space constraints limit your options. Measuring just 33 inches in length and 19 inches in width, this horizontal configuration fits easily beneath workbenches, alongside buildings, or in utility closets where larger capacity containers won't accommodate. Homeowners frequently select this size for emergency preparedness kits, small-scale irrigation systems, or backup water supplies that need to remain accessible yet unobtrusive.
Stable Construction Without Complex Installation
The horizontal leg design provides exceptional stability without requiring additional mounting hardware. Four integrated support legs distribute weight evenly across the base, preventing tipping or shifting even when positioned on slightly uneven surfaces. This self-supporting structure eliminates installation complexity, allowing you to position your water storage wherever it's most convenient. The 8-inch threaded lid provides straightforward access for filling, cleaning, and maintenance tasks while maintaining a secure seal that prevents contamination.
Portable Water Storage for Agricultural Operations
Agricultural applications benefit significantly from the portability this size offers. Whether you're supplying water to remote pastures, supporting greenhouse operations, or maintaining livestock in multiple locations, the manageable weight when empty (17 pounds) allows one person to relocate the tank as needs change throughout growing seasons. The rotationally molded construction ensures consistent wall thickness throughout the entire vessel, creating a reliable container that withstands the rigors of farm environments.
Temperature Range for Diverse ApplicationsTemperature versatility extends the practical applications beyond basic water storage. With a maximum operating temperature of 140°F, this poly tank accommodates warm water applications, including solar-heated systems, equipment cleaning operations, and industrial processes requiring moderate temperature fluids. The 1.2 specific gravity rating confirms compatibility with water and similar density liquids, though non-potable applications should always be verified against chemical compatibility charts.
Weather-Resistant Protection for Outdoor Use
UV inhibitors integrated throughout the polyethylene resin protect your stored contents from degradation caused by direct sunlight exposure. This weatherproofing feature allows confident outdoor placement in gardens, on patios, or beside structures where shade is limited. The three-year warranty provides additional assurance that your investment in reliable water storage will serve you well into the future, backed by a manufacturer committed to product quality and customer satisfaction.

Frequently Asked Questions
Can this 35-gallon water tank be used for drinking water storage?
Yes, this tank is manufactured from food-grade polyethylene suitable for potable water storage. However, we recommend thoroughly rinsing the tank before initial use and ensuring any fittings or accessories you install are also food-grade rated. Regular cleaning maintains water quality over extended storage periods.
What's the best way to fill this horizontal water storage tank?
The 8-inch threaded lid on top provides convenient access for filling using a standard garden hose or bucket. For automated filling, you can install bulkhead fittings (sold separately) in the side wall to connect directly to water lines or pumps. Always avoid overfilling to allow for thermal expansion.
How do I prevent algae growth in my 35-gallon tank for water storage?
Algae requires light to grow, so positioning your tank away from direct sunlight helps considerably. Additionally, keeping the lid tightly sealed prevents airborne spores from entering. For long-term storage, consider adding a water preservative designed for potable water tanks.
Will this 35-gallon poly tank for water storage work in freezing temperatures?
Polyethylene tanks handle cold temperatures well, but water expands when frozen and can crack any container. If you live in an area with freezing winters, either drain the tank before temperatures drop or keep it in a heated space. Never fill completely in cold climates – leave 10-15% air space for expansion.
