This series of pictures shows how the equipment (pictured in the foreground) heats, stores, and pumps the warm water.

The farm needed several batches of warm water. This All-American candidate standing in the Aqua Cow tank was not "down". She had a bruised, swollen udder, and her owners wanted to use the tank for repeat treatments with epsom salts to reduce swelling and to hasten circulation and healing. The dairy also had a fresh heifer with stiffness and swelling that also could benefit from warm water therapy.

The farm couldn't provide the warm water, and trucking warm water to the farm for several days was impractical. They needed portable equipment.
