JUG Waterers by Bakko Industries, Inc.
For almost 3 decades, JUG Waterers have been providing horses with the freshest, cleanest water available to them.

About Bakko Industries, Creator of JUG Waterer

The JUG was developed in central Iowa in the early 1980s, and came on the market in 1984. Bakko Industries (a family owned company at Glenwood Minnesota) purchased the JUG product line in 2005. The JUG is marketed throughout the US, and Canada, mostly through Bakko's Territory Rep / Dealer Network. Open territory, and overseas sales are handled directly out of the Glenwood office. Bakko Industries continually strives to produce the highest quality products possible, and follows the sale with excellent, friendly, and informed customer service. Water is the most vital nutrient your horses can have! Even though you provide access to water for your horses, it does not necessarily mean they are staying properly hydrated. The quality of their water can deter them from drinking, thus limiting their daily intake for digestion, energy, and overall health.

How The JUG Works-- a Natural Drinking Design

Thanks to the open bowl design and unique draw tube water supply system, horses can see and smell clean, fresh water. No learning how to lift flaps or push balls or floats out of the way to get a drink. A horse simply places its mouth in the open pool of water in the drinking bowl and sucks up the water just as it would from a natural water hole.


Jug Is Designed To Provide Your Horse With Clean Drinking Water

JUG Waterers feature a weather-sealed water reservoir which blocks out sunlight. This virtually eliminates algae growth in the tank. Water is fed to the open drinking bowl through the draw tubes. These tubes are attached to the drinking bowl with a feed trap which keeps feed debris from the horse’s mouth out of the reservoir, thus reducing any bacterial growth. As a horse drinks from the JUG, a suction/swirling action is created in the feed trap area. This action causes feed from the face of the horse to be consumed as it drinks. And because water is "turned over" whenever a horse drinks, there is always clean, fresh water in the bowl.

Even though the design of our units keeps the water free from feed or hay, most water contains iron bacteria which will leave a residue in the tank over time. The external drain plug will allow you to easily drain water from the tank periodically. Once the unit is full again, an internal pilot-operated float valve automatically keeps the water in the bowl at the determined level. The water level is easily adjusted from the outside of the JUG.


Natural Thermal Energy-- NO "Electricity" Required!

Jug Waterers rely primarily on thermal energy (not electrical) to help regulate a constant water temperature. This means warmer water in the winter and cooler water in the summer for your horses to drink. This is accomplished through the following design features:

* Draw Tube Water Supply System - There are actually three draw tubes in the unit, two copper and one Cpvc. As the water gets cold in the bowl, it becomes heavier and sinks down the Cpvc tube, forcing warm water from the tank up the copper tubes and into the feed trap area and bowl. Since copper is an excellent heat conductor, heat is transferred during this water replenishment process, keeping the water in the bowl from freezing.
* JUG Earth Tubes - Stand-alone models are often installed with insulated and uninsulated earth tubes. These create a heat well under the unit which supplies additional heat from the ground. The insulated tube extends below the frost line, minimizing heat escape to the frozen ground in winter. When heat from the ground flows through the uninsulated tube into the heat well, it is used as additional energy to keep the water in the JUG fluid.

The JUG Saves You Money On Utility Costs!

In marginal climates you need enough horses to keep the water in the tank warm enough to provide heat energy (at least 15 head per bowl). Otherwise, a low wattage heater and thermostat are recommended.

Note: In 2021, a research study* performed and published in the Iowa Sate University Animal Industry Report concluded that JUG Waterer units with heat output (thermostat) control reduced the energy usage by 85% over a competitor’s waterers without thermostats or earth tubes. The JUG Waterer units cost only $0.11 per day to operate. The utility cost savings was over $110 during the study period.
*The study was conducted at Iowa State University Beef Nutrition Farm in Ames, IA from October 23 thru December 14, 2020.

With The JUG- You Get Quality at Every Turn!

The exterior design of our JUG Waterers, coupled with out patented clean water technology inside, promotes a natural drinking experience your horses will enjoy.

Our Stand-Alone Waterers come in three models:

Single Bowl, Double Bowl, and Four Bowl. The durable rotomolded polyurethane construction makes them tough on the outside, while weather-sealing keeps the inside free of dirt and debris. All three models are equipped with an anti-siphoning float valve to prevent back siphoning into your water supply. An exterior inspection plate can be easily removed for examination and service to the float valve. An external adjustment screw (to minimize the amount of water exposed to the weather) and drain plug are included for hassle-free maintenance.

What About JUG Waterer For Your Horse Stalls?

The same clean, fresh water technology of the stand-alone models are also offered in a stall version for your horse's stalls. . Available in both wall and corner mount, the Stall Waterers feature strong polyethylene construction with an 18 gauge stainless steel bite guard (which prevents damage from cribbing). With its 2 gallon reservoir and quick recovery float valve, the stall units offer plenty of water capacity for your horses. For colder climates (or if you have a cold barn), we offer a low 30-watt thermostatically controlled heated version for the assurance of frost-free water. And our insulated rise tube protects the water supply line from the cold. For warmer climates (or if you have a heated barn), our energy free version is the model of choice.

Of Course, We Have the Strongest Warranty in the Industry!
JUG Waterers are backed by the strongest warranty in the industry, along with the highest possible level of customer service. Due to the minimal maintenance features of the JUG, warranty needs are typically uncommon. However, should an issue ever arise, we offer the following against manufacturer defects:

* 2 Full Year Warranty on float valve parts and electrical components
* 15 Year Prorated Warranty on bases and lids

In addition, we offer a 60 Day Satisfaction Guarantee. If you’re not satisfied with the quality of our product or the water it provides, we will gladly buy it back from you within 60 days of purchase.

Now You Know The Facts, Don't Your Horses Deserve The JUG?
We believe they do! Best design, natural drinking, and most powerful warranty in the industry. Call us today and let us help your horse enjoy the benefits that JUG has to offer!

What makes the JUG Waterer drink like a natural water source?

The JUG uses an open-bowl design paired with a patented draw-tube water supply system, so horses can see and smell clean, fresh water exactly the way they would at a pond or stream. There are no flaps or paddles to push and no float for the animal to manipulate, which removes the hesitation that keeps shy or young horses from drinking. A weather-sealed reservoir blocks sunlight to stop algae growth, and a feed trap keeps hay, grain, and debris out of the tank. Because the quality of the water can deter a horse from drinking, this clean-water focus is the heart of the design and directly supports daily intake for digestion, energy, and overall health.

How does the JUG keep water from freezing without burning electricity?

The JUG relies primarily on thermal energy, not electrical heat, to hold a constant water temperature. Each bowl is fed by three draw tubes, two copper and one Cpvc: as the water in the bowl cools it grows heavier and sinks down the Cpvc tube, forcing warmer reservoir water up the copper tubes and into the bowl. Copper is an excellent heat conductor, so this constant convection transfers heat into the bowl and keeps it from freezing. The result is water that runs warmer in winter and cooler in summer, with a reported seasonal electric cost averaging $10.00 for the entire season on units that use the optional heater.

The corner-mount and wall-mount stall waterers built for horses

For barns, Bakko Industries makes a dedicated equine stall waterer in two mounting styles: a Corner Mount for the corner of a stall and a Wall Mount (flat back) for a flat wall surface. Both share a 2-gallon reservoir, rotomolded plastic construction with rounded edges, and a stainless steel bite plate that protects the unit from cribbing horses. A marked water-level line on the bowl shows the suggested fill height, a quick-recovery float valve with an adjustment screw refills the bowl fast, and an external drain plug makes cleaning simple. For cold regions a 30-watt thermostatically controlled heated version delivers frost-free water in an unheated barn.

Earth Tubes and riser tubes that pull heat from the ground

Stand-alone pasture JUGs can be installed with insulated and uninsulated JUG Earth Tubes that create an underground heat well reaching below the frost line. Heat flowing up through the uninsulated tube into the heat well becomes extra energy that helps keep the JUG water fluid, while the insulated tube minimizes heat loss to the frozen ground. Stall units use 4-inch Schedule 80 PVC riser tubes with a 2-inch Schedule 40 PVC interior; the insulated version is spray-foam injected for cold climates, and both protect the water line from animal kicks. Water can be supplied bottom-fed through the riser tube or fed overhead through a back-corner access hole.

Pasture models sized from a single bowl to four bowls

The pasture line scales to the size of any operation. The Single Bowl measures 25 inches long by 20 wide by 24 high, holds 7 gallons, weighs 53 lbs, and serves up to 25 dairy, 50 beef, or 75 sheep. The Double Bowl is 41 by 20 by 22.5 inches, holds 14 gallons, weighs 76 lbs, and serves up to 50 dairy, 100 beef, or 150 sheep. The Four Bowl unit is 39 by 37 by 22 inches, holds 45 gallons, weighs 105 lbs, and serves up to 125 dairy, 250 beef, or 300 sheep. Every model includes anti-siphoning float valves, external inspection covers, adjustment screws, and drain plugs for maintenance.

The Solution Section (FAQ)
How do JUG Waterers keep water clean without flaps or floats?
JUG Waterers use an open bowl design fed by a unique draw tube water supply system, so horses can see and smell clean, fresh water and simply drink from an open pool the way they would from a natural water hole. A weather-sealed reservoir blocks sunlight to virtually eliminate algae growth, and a feed trap keeps feed debris out of the tank. Because the water is turned over every time a horse drinks, there is always fresh water in the bowl.
Do JUG Waterers require electricity to keep water from freezing?
No electricity is required for the core design. JUG Waterers rely primarily on thermal energy to regulate water temperature, using three draw tubes (two copper and one CPVC) so cold water sinks and forces warmer tank water up the copper tubes, which conduct heat to keep the bowl from freezing. Stand-alone models are often installed with insulated and uninsulated earth tubes that draw additional heat from the ground below the frost line.
How much does a JUG Waterer cost to operate?
In a research study published in the Iowa State University Animal Industry Report, JUG Waterer units with heat-output (thermostat) control cost only $0.11 per day to operate. The study found these units reduced energy usage by 85% compared to a competitor's waterers without thermostats or earth tubes, for over $110 in utility savings during the study period. The study ran at the Iowa State University Beef Nutrition Farm in Ames, IA from October 23 through December 14, 2020.
What stand-alone JUG Waterer models are available?
Stand-alone JUG Waterers come in three models: Single Bowl, Double Bowl, and Four Bowl. They are built with durable rotomolded polyurethane that is tough on the outside while weather-sealing keeps the inside free of dirt and debris. All three include an anti-siphoning float valve, a removable exterior inspection plate for servicing the valve, an external water-level adjustment screw, and a drain plug for easy maintenance.
Is there a JUG Waterer for horse stalls?
Yes. The same clean, fresh water technology is offered in a stall version available in both wall and corner mount. The Stall Waterers feature strong polyethylene construction with an 18 gauge stainless steel bite guard to prevent cribbing damage, a 2 gallon reservoir, and a quick recovery float valve. A low 30-watt thermostatically controlled heated version is available for colder climates, while an energy-free version suits warmer climates or heated barns.
How many horses do you need for a JUG Waterer to stay frost-free without a heater?
In marginal climates you need enough horses drinking from a bowl to keep the tank water warm enough to provide its own heat energy — at least 15 head per bowl. With fewer horses than that, a low wattage heater and thermostat are recommended to keep the water fluid in cold weather.
What warranty and guarantee come with a JUG Waterer?
JUG Waterers are backed by a 2 full year warranty on float valve parts and electrical components and a 15 year prorated warranty on bases and lids, all against manufacturer defects. They also include a 60 Day Satisfaction Guarantee — if you are not satisfied with the product or the water it provides, Bakko Industries will buy it back within 60 days of purchase. Because of the JUG's minimal-maintenance design, warranty needs are typically uncommon.
How can I learn more or order a JUG Waterer?
JUG Waterers are made by Bakko Industries, Inc., a family-owned company in Glenwood, Minnesota, and are sold throughout the US and Canada, largely through Bakko's Territory Rep and Dealer Network. You can call 800-584-6675 to talk with their friendly staff or visit https://www.bakkoindustries.com/jug-waterers to learn more. Open territory and overseas sales are handled directly out of the Glenwood office.
How does the JUG Waterer keep water from freezing without electricity?
It relies primarily on thermal energy rather than electric heat. Three draw tubes (two copper, one CPVC) create a natural convection loop: cooling water in the bowl sinks down the CPVC tube and pushes warmer reservoir water up the copper tubes. Because copper conducts heat well, this constant exchange keeps the bowl water fluid in cold weather.
Is the JUG truly energy-free for horses?
In the right conditions, yes. Stand-alone pasture units use ground heat through optional JUG Earth Tubes plus the copper draw-tube convection system to stay frost-free with no power. In marginal climates or with fewer than about 15 head per bowl, a low-wattage heater and thermostat are available, and Bakko Industries reports that option averages about $10.00 in electricity for the entire season.
Does Bakko Industries make a JUG waterer specifically for horse stalls?
Yes. There is a dedicated stall waterer with a 2-gallon reservoir, available as a Corner Mount for stall corners and a Wall Mount (flat back) for flat walls. Both use rotomolded plastic with rounded edges and a stainless steel bite plate to resist cribbing damage.
What is the stainless steel bite plate for?
Horses that crib or chew can damage plastic fixtures over time. The stainless steel bite plate on the stall waterer protects the unit's edge from that chewing and cribbing behavior, extending the life of the waterer in a horse stall.
How many horses can a JUG bowl serve?
Capacity is rated by species. A single bowl serves up to 25 dairy, 50 beef, or 75 sheep; a double bowl handles up to 50 dairy, 100 beef, or 150 sheep; and a four-bowl unit serves up to 125 dairy, 250 beef, or 300 sheep. For horses on the energy-free system, Bakko recommends at least 15 head per bowl in marginal climates so the herd's drinking keeps reservoir water warm enough; otherwise the optional heater is used.
What sizes and capacities do pasture JUG waterers come in?
There are three pasture models. The Single Bowl holds 7 gallons (25x20x24 inches, 53 lbs), the Double Bowl holds 14 gallons (41x20x22.5 inches, 76 lbs), and the Four Bowl holds 45 gallons (39x37x22 inches, 105 lbs).
What are JUG waterers made of?
The pasture units use durable rotomolded polyurethane construction with a weather-sealed reservoir. The horse stall waterers use rotomolded plastic with rounded edges and a stainless steel bite plate. Internal plumbing uses copper and CPVC draw tubes, and stall riser tubes are PVC.
How does the JUG keep the water clean?
The reservoir is weather-sealed and blocks sunlight, which prevents algae from growing in the tank. A feed trap stops hay, grain, and debris from getting into the reservoir, and the suction and swirling action created in the feed-trap area as the animal drinks helps clear feed from the bowl. The open-bowl design lets the horse see and smell clean water before drinking.
Why does water cleanliness matter for a horse's health?
Poor water quality can discourage a horse from drinking, which limits daily intake. Adequate water intake is essential for digestion, energy, and overall health, so a clean, fresh, algae-free supply encourages horses to drink the amount they need.
What are JUG Earth Tubes?
Earth Tubes are an installation option for stand-alone pasture units that create an underground heat well. Heat from the ground flows up through an uninsulated tube into the heat well to add thermal energy that keeps the JUG water fluid, while an insulated tube extends below the frost line to minimize heat loss to frozen ground in winter.
How is a stall waterer plumbed and installed?
Stall units use 4-inch Schedule 80 PVC riser tubes with a 2-inch Schedule 40 PVC interior, which protect the water line from animal kicks. The insulated version is spray-foam injected for cold climates, and the uninsulated version suits warm or heated barns. Water can be bottom-fed through the riser tube or supplied overhead through a back-corner access hole.
Is there a heated version for very cold barns?
Yes. The stall waterer offers a 30-watt thermostatically controlled heated version that provides frost-free water in unheated barns. It only draws power as the thermostat calls for it, keeping operating cost low.
How do I keep the JUG waterer clean and maintained?
Every model includes maintenance-friendly features: external inspection covers, an external drain plug for emptying and cleaning, and a float valve with an adjustment screw. The stall waterer's quick-recovery float valve refills the bowl fast and is easy to access for service.
How long have JUG Waterers been on the market?
The JUG was developed in central Iowa in the early 1980s and came on the market in 1984. Bakko Industries, a family-owned company in Glenwood, Minnesota, later purchased the JUG product line, and the waterers have been providing livestock and horses with fresh, clean water for nearly three decades.
Who makes JUG Waterers and where are they located?
JUG Waterers are manufactured by Bakko Industries, Inc., a family-owned company based at 28958 198th Avenue, Glenwood, MN 56334.
How do I buy a JUG Waterer or get pricing?
