Hastings Round Water Tanks for Livestock
Hastings round poly stock tanks provide an open watering area for cattle, horses and other suitable livestock. Choose approximately 320, 580, or 1,100 gallons of storage, with a round footprint that allows access around the tank where the site layout permits.
The tanks use high-density virgin polyethylene with UV resistance for outdoor service. Their molded bodies resist rust and corrosion, while the closed top lip and reinforced sidewall design support the tank during everyday livestock use. They provide a practical watering option where you want a large open reservoir without a galvanized steel body.
Shipping and Order Requirements
Shipping notes: These poly stock tanks are designed to nest inside each other and ship in bulk, and we are unable to ship individual tanks. Please email or call for a shipping quote before placing an order.
Due to their large size, the 10' diameter tanks cannot ship with common carriers and are only available in large quantities or for pick up in Hastings, NE.
Compare Round Tank Sizes
| Nominal Diameter | Height / Depth | Approx. Capacity | Approx. Empty Weight |
|---|---|---|---|
| 6 feet | 24 inches | 320 gallons | 55 pounds |
| 8 feet | 24 inches | 580 gallons | 83 pounds |
| 10 feet | 28 inches | 1,100 gallons | 135 pounds |
Sizes are nominal. Hastings notes that the top lip makes actual overall dimensions larger than the stated size. Confirm the measurements if the tank must fit through a gate or within a specific space. The 10-foot tank is 28 inches deep, rather than the 24-inch depth of the smaller models.
Original Capacity Reference Chart

Choose Capacity Around Your Watering Routine
Tank capacity is only one part of a livestock watering plan. Consider how many animals use the location, how quickly the supply refills the tank, and how often you can inspect it. Larger storage can provide a useful reserve between refills, but it does not make a slow or unreliable supply adequate on its own.
The 6-foot tank has the smallest footprint in this range. The 8-foot option increases storage while keeping the same listed depth, and the 10-foot tank provides the greatest capacity. Check rim height and access for the animals using the tank, especially where younger or smaller livestock share a watering point.
Polyethylene Construction and Outdoor Durability
A single molded body avoids the joined metal seams used in many steel tanks. The polyethylene will not rust, and Hastings specifies resistance to feedlot acids and UV damage. The closed lip reinforces the upper edge, helping the tank retain its shape during normal use.
Durability still depends on placement and care. Protect the tank from machinery impacts, dragging damage, and uneven support. The reinforced rim is a construction feature, rather than a guarantee that livestock pressure or other forces can never damage the tank.

Placement, Drainage and Filling
Set the empty tank on a firm, level surface that supports its base evenly. Plan the location before filling because a full tank carries substantial water weight. Leave room for animals to approach and for people or equipment to reach the drain and water supply.
Manage runoff so the watering area does not become persistently muddy. If you plan to use a float valve, confirm the fitting and mounting arrangement for the tank's closed lip. These are open stock tanks, not heated or insulated waterers, so freezing-weather operation requires separate planning.
Drain Plug and Routine Cleaning
The listed round models include a drain plug for emptying and maintenance. Check the plug and fitting before filling, then inspect them during routine cleaning. Remove sediment and buildup, clean the interior as appropriate, and rinse before returning the tank to service.
Choose a cleaning schedule based on use and water condition. An open reservoir makes visual checks straightforward, but stored water still needs regular attention. Watch the refill supply and inspect for debris, algae, or contamination rather than judging water availability by tank size alone.
Manufacturer Warranty
Hastings provides a three-year warranty on materials and workmanship for its poly stock tanks, subject to the manufacturer's terms. Keep your purchase information and contact Barn World if you need help identifying the tank or discussing a potential claim.
Frequently Asked Questions About Hastings Poly Tanks
Which capacities are available?
The round models listed here hold approximately 320, 580 and 1,100 gallons. Their nominal diameters are 6, 8, and 10 feet, respectively.
Are all three tanks two feet deep?
No. The 6- and 8-foot models are listed at 24 inches deep. The 10-foot model is 28 inches deep.
Are the diameter measurements exact overall dimensions?
No. They are nominal sizes. The top lip increases the overall dimensions, so confirm actual measurements for a tight installation or access opening.
Can I order one tank for delivery?
Barn World cannot ship individual tanks from this range. They are designed to nest for bulk shipping. Request a quote before ordering; the 10-foot model has additional delivery restrictions and may be available for pickup in Hastings, Nebraska.
Will the polyethylene rust?
No. The poly body does not rust like steel. It can still be damaged by impacts, abrasion or unsuitable placement, so regular inspection and proper support remain important.
Does the tank have a drain?
Yes. All three listed round models include a drain plug. Confirm the fitting on your tank when ordering replacement parts.
Can these tanks be left outside year-round?
They are designed for outdoor livestock watering, but they do not provide automatic freeze protection. Plan winter use around local conditions and the suitability of any separate heating or watering equipment.
What warranty is included?
Hastings specifies three years of coverage for materials and workmanship, subject to its warranty terms. This is separate from ordinary maintenance and does not promise an unlimited service life.
