Poly Livestock Water Tanks

These heavy-duty poly livestock tanks are built to perform in demanding farm and ranch environments where traditional metal tanks often fail. Constructed from high-quality polyethylene, they resist rust, corrosion, and damage caused by harsh feed pen acids, making them a long-lasting and low-maintenance solution for watering livestock.

Each tank is manufactured using a rotational molding process that creates a seamless, one-piece design with no thin spots or weak seams. The reinforced walls and strong rolled top edge add extra durability, helping the tank maintain its shape and strength even under heavy daily use.

For added convenience, every poly livestock tank includes a built-in drain plug that makes emptying, cleaning, and routine maintenance fast and easy. These tanks are ideal for cattle, horses, and other livestock needing reliable access to clean water year-round.

The rotational molding process ensures there are no thin edges, seams, or weak spots prone to leaking or damage. We also carry round-end stock tanks. Using polyethylene eliminates any chance of denting, rusting, or splitting along seams that can lead to leaking. The smooth poly edges and corners also enhance safety, as there are no sharp metal edges hanging out for your animals to cut themselves on. See all of our animal's safe plastic stock tanks.

Please forward the quantities and sizes you'd like and we'll forward a quote for your review. The tanks are available in 6, 7.5 and 9' diameters and are designed to nest inside each other to save on shipping.

The poly round stock tanks are available for pick up in Sioux Falls, SD. If a will-call order would be of interest to you, please let us know and we'll set some aside for you.

These tanks ship from South Dakota and unfortunately the shipping for one or two will be near the cost of the tank themselves. We would see more economies of scale when shipping 4-5 tanks as they do nest inside each other. If that would be of interest to you, please let us know and we'll reply with a quote for your review.
