Livestock Water Systems

Where can livestock water come from?

Common sources include private wells, springs, ponds, streams, rural water district connections and hauled water. Each has trade-offs. Wells can be dependable but need power or a pump. Ponds and streams are cheap but can carry contamination and are easily fouled by animals themselves. Rural water connections are steady but cost money by the volume used.

Rules about using surface water, building ponds and drilling wells vary by state and county. Check with your state water agency and your county office before you build anything.

How do I get water to the animals?

Options range from gravity-fed lines and solar pumps to electric pumps and frost-protected tanks. Placing tanks where several paddocks can share them cuts the number of tanks and the work. Keep lines buried or protected where animals, vehicles or freezing can reach them.

Think about elevation, distance and power. A long run uphill needs a strong pump and more energy, while a spring above the pasture may supply water with no power at all. Your NRCS office can discuss design options and possible assistance.

Freezing deserves its own thought if you live where winters are hard. Shallow lines, exposed pipe and float valves are the first things to fail in a cold snap. Burying lines below the local frost depth, which your extension or NRCS office can tell you, and using tanks designed for winter use will save you from breaking ice every morning. The companion article on winter livestock watering covers this in more detail.

• Tanks that animals can reach from every field or pen.
• Float valves protected from being damaged by animals.
• Shutoff valves so you can repair one section without losing all water.
• Overflow directed away from wet, muddy ground.

How do I keep water clean?

Dirty water reduces drinking, and reduced drinking affects health and growth. Algae, manure and feed in tanks are the usual problems. Place tanks on firm, well drained footing with a gravel or concrete pad so animals are not standing in mud.

Scrub tanks on a regular schedule. If you use ponds, fencing animals out and piping water to a tank away from the bank protects water quality and the shoreline. Your extension office can advise about testing when water looks or smells unusual.

How much water do animals need?

Needs rise with heat, lactation, dry feed and body size. A nursing mother or an animal in hot weather drinks far more than the same animal in a cool week. Rather than looking for a single figure, make sure your system can supply much more than average demand at the hottest time, and that animals can all drink without bullying.

Allow enough tank space so low-ranking animals can drink. A tank that is too small or too crowded leaves the weakest animal thirsty.

What about heat, drought and power outages?

Plan your system for the worst week of the year. In heat, water warms and consumption spikes. In drought, ponds and shallow wells can fail. Keep a backup plan such as hauling water, a generator for the well pump, or a stored supply. Drought.gov provides local drought information and your county may share conditions and assistance.

Check on tanks daily in extreme weather, since a failed float valve or a dead pump can empty a tank in hours.

How do I plan for the long term?

Draw a simple map of your water lines, valves, tanks and power. Keep a spare parts kit for common failures. Review the system each season, because small leaks and corroded fittings grow slowly and then fail at the worst time.

If you are adding animals, check capacity first. A system that suits a small group may not keep up with a larger one.

What backup should I have when water fails?

Think through three failures: the pump stops, the line freezes or breaks, and the source itself runs low. For each, decide in advance what you will do within the first hour. That might mean a hose to a stock tank from the house, a stored barrel, or a call to a neighbor who can lend a tank. Practice the steps once so you know what equipment you actually need.

Keep records of when problems happen and what fixed them. A pattern, such as a line that always freezes at the same low spot, shows you where to invest in repairs or insulation. Your extension office can help you think through options that fit your budget.

• A spare pump or float valve if you rely on one.
• Hoses that reach each tank, stored where they will not freeze.
• A written plan for the first hour of a water failure.
