Rubbermaid 300-Gallon Stock Tank – Heavy Duty Rigidcell Construction
Best for large operations requiring a high-capacity, durable water or feed container. The stock tank features rigidcell construction for long-lasting performance in all weather conditions. It is backed by a category-leading 10-year limited warranty and proudly made in the USA. This model suits cattle operations, large livestock areas, or outdoor clean-up tasks where volume matters. Caution: very large footprint; ensure space and transport capacity before purchase.
Behlen Country Little Giant Oval 15 Gal Stock Tank
Best for small to medium setups needing a compact, easy-to-move waterer. The oval shape provides a balance of capacity and space efficiency, making it suitable for limited outdoor areas. Designers emphasize simplicity and reliability for day-to-day farm tasks. Limitation: smaller capacity than larger stock tanks, so not ideal for high-volume water needs.
Behlen Country Farm Flex 6ft x 2ft Round Stock Tank
Best for moderate to large outdoor storage needs with a flexible, sturdy poly design. The Farm Flex stock tank offers ample space for water or feed and is designed to withstand outdoor conditions. Choose this if you need a longer, rectangular footprint without sacrificing round-tank reliability. Caution: shape and size may require adequate space for full use and cleaning.
Rubbermaid 50-Gallon Black Plastic Stock Tank
Best for medium storage needs or as a compact water trough. This BPA-free, weather- and abrasion-resistant stock tank is suitable where a smaller, reliable container is required. It is a practical option for smaller operations or as a secondary tank. Limitation: lower capacity compared to larger tanks for high-volume water tasks.
Buying Guide
Key considerations when selecting heavy duty stock tanks include capacity, material, durability, and intended use. Below are practical questions and guidance to help compare options.
- What capacity best fits my operation? Large farms benefit from 300+ gallon tanks, while small ranch sites may do well with 15 or 50 gallons. Consider daily water or feed demand and space for placement.
- What material meets my weather and terrain needs? Poly and plastic tanks are lightweight and cost-effective, while rigid plastic variants offer long-term durability in harsh climates. Steel or metal options are typically heavier and more durable in extreme conditions, if available.
- Is a warranty important for long-term usage? Tanks with extended warranties provide confidence for outdoor installations and frequent use.
- Will the tank’s shape influence handling and cleaning? Oval shapes or longer footprints can affect space utilization and ease of maintenance.
- Are there safety considerations? Ensure the tank is BPA-free if used for drinking water and verify compatibility with livestock or pets to avoid injury or contamination.
- Can the container serve multiple roles? Some stock tanks double as feed tubs, wash basins, or temporary pools; align the model with your primary need to maximize value.
