| Tough, Durable, and Dependable  The JUG is a heavily insulated, tough, livestock waterer that provides clean, cool water to your animals. It is well suited for herbivores of all sizes. The open-bowl design makes it easy to use by young sheep, goats, calves and foals, yet rugged enough for use by mature cattle, horses, bison, and elk. There are no balls, lids, or flaps for animals to move out of the way. Patented
Draw Tube Design:  The unique draw tube works like a giant straw - the animal uses its normal method of drinking by placing its muzzle over the opening in the drinking bowl and sucking up the water, just as it would drink from a natural water hole. The draw tube is attached to a feed trap that prevents feed debris that falls off of the animals' mouths from entering the reservoir, keeping the water in the tank exceptionally clean. An external adjustment screw allows you to easily raise or lower the water level in the drinking bowl. The JUG is available in one, two, and four bowl models:
1 bowl
7 gallons
45 lbs.
26" long x 21" wide x 23" high 
2 bowl
16 gallons
72 lbs.
42" long x 21" wide x 23" high

• Perfect for the littlest lamb or the biggest bull How animals drink from the JUG:  It all hinges on the “draw tube” - a word coined to describe a unique design for supplying the animal with water. It is much like a giant straw so the animal can use its normal method of drinking. The animal places its muzzle over the opening in the drinking bowl and sucks up the water just as it would drink from a natural water hole. Even timid animals adapt to the Jug easily. Clean Fresh water: Designed for clean, clean water: JUG water is clean. No more smelly water from heavy bacterial growth. The draw tube is attached to the drinking bowl with a feed trap (see above) which keeps feed debris that falls from the animal’s mouth from dropping into the reservoir. Besides sucking up water, the animal draws up any accumulated debris in the trap and bowl areas, providing further assurance of cleanliness. With the JUG waterer, you will not have the usual slime problem. Additionally, of course, no algae will grow in the JUG since it is a light-tight waterer. The bowl is sealed with Weather Seal. Water is a nutrient and absolutely essential for maximum productivity. You know what the vets say: If the water is palatable, the animal will drink the quantities it needs for maximum feed efficiency and rate of gain.
Quality = Quantity = Productivity It's easy to acclimate animals to the JUG
 With the JUG, animals can see and smell clean water. They do not have to learn to lift flaps or push balls and floats out of the way to get a drink, but they do have to know where the water is located. To this end, the JUG has an external adjustment screw (simply turn the screw with a coin) - there is no lid to remove - which allows you to raise the water level in the drinking bowl. When the animals know the JUG is their drinking station, return the water to its lower operating level to minimize the amount of water exposed to the weather. An internal, pilot-operated float valve automatically keeps the water at the determined level.
Thermal energy, supplemented with electrical energy
The draw tube is really three tubes: two copper and one CPVC. As the water gets cold in the drinking bowl, it becomes heavier and sinks down the CPVC tube, forcing the warm tank water up the copper tubes into the drinking bowl. This keeps the water in the bowl from freezing by slowly circulating it and replenishing it with warm water. In addition, the copper tubes are designed with a large surface area in the trap. Since copper is an excellent conductor of heat, heat is transferred from tank water to the trap area through the copper tube walls. One copper tube conducts sufficient heat to keep water from freezing in the bowl, but we have in two for safety.
The JUG will operate energy free with a minimum number of animals drinking from it. The Energy Efficient (with heat) units work fine no matter how many or few animals you have drinking from the JUG. A small 65-watt heater is used to make the JUG energy-efficient. In either case, it is primarily thermal energy, not electrical energy, keeping the water fresh and at a constant temperature, summer and winter. In 1993-94, an electrical consumption test was conducted at Northeast Iowa Community College in Calmar, Iowa. This, in the end, was the third coldest winter in recorded Iowa history. The JUG used 108 Kw-hrs for the 120 day trial. At 8 cents/Kw-hr, it used only $8.64 of electricity.
The JUG is super-insulated with urethane foam to conserve heat loss, but the middle of the bowl area is left free of insulation so the internal heat will melt away ice that could form on the exterior from sloppy drinking. The Jug is very reliable in extreme cold and wind chills. It's like a Thermos jug.
External Drain Plug  The external drain plug makes it easy to drain water from the JUG tank. The JUG’s design keeps the water free from feed or hay, but most water has iron bacteria which will leave a
residue in the tank over time. It is, therefore, wise to
drain the tank periodically. We recommend once a year, in the fall, when you check the heater and thermostat prior to the on set of cold weather
Inspection Cover  The JUG has an inspection cover that can be easily removed for inspection and service to the float valve. Milk inspectors requested that we provide this so they can easily check to see if the JUG is meeting requirements.
Energy-Free & Energy-Efficient
Installations Using Earth Tubes
Energy-Free:
The energy-free JUG uses energy from ground water (45o to 550F if
the supply line is buried at least 18" to 24" below the frost line and
from a heat well to prevent freezing of water in the tank and bowl.
The JUG is super-insulated and has very little heat loss.
When an animal drinks, the water in the JUG is replenished by the
warm ground water. In addition, when using an insulated earth tube
and an uninsulated earth tube, a heat well is formed which supplies additional energy from the ground. The insulated earth tube extends below the frost line which prevents heat loss to the frozen ground in winter. The heat well works because heat from the warm ground flows through the uninsulated earth tube into the heat well and then is used as additional energy to keep water in the JUG from freezing.
In summary: Heat from the incoming warm water and heat from the
ground that flows into the heat well is used to keep the JUG
frost-free. There must be the recommended minimum number of
animals drinking (10 cattle per drinking bowl) to replenish the water
in the JUG tank.
Energy-Efficient:
The Energy-efficient JUG is the model of choice if there are fewer
than the recommended minimum number of animals drinking, or if
you live in an area where long cold winter storms can cause
prolonged periods of non-drinking by the animals. The small,
low-wattage heater provides "insurance".
JUG Product History
The JUG
waterers were designed by Wayne Noland of Carlisle, Iowa. In 1990, the
family company was sold to Bill Edstrom, who later moved production to
Wisconsin, and it became a part of Edstrom Industries, Inc. Bakko
Industries, Inc. purchased the agricultural watering product lines from
Edstrom Industries in 2005, and production has since moved to Glenwood,
Minnesota.
