Find a large container that will hold water. The size of container depends on the size and quantity of animals that will be using it. Plastic or metal containers will be sufficient; it just needs to be large enough to be effective.
Place the container in an open area where the livestock can have access to it. Attach one end of a garden hose to a nearby spout.
Place the other end of the hose inside the trough. Fill the container with water. Turn the water off once the trough is filled to the top. Check the container often to make sure clean, fresh water is available to the animals throughout the day.
