Abstract
A recirculating, animal watering system has an upright reservoir with a tubular sidewall extending between upper and lower end caps. The sidewall has an open mouth nearer the upper end cap. Thus the reservoir below the mouth serves as a water supply pool. A water supply conduit extends vertically from a lower communication port submerged in the water supply pool and at least one fountain discharge outlet arranged in the reservoir above or at the level of the mouth. An air supply line is included and extends between a source of pressurized air and a submerged air injection site into the water supply conduit. Given the foregoing, a small steady stream of air lifts water from the water supply pool, up the water supply conduit by plug or slug flow and out through the at least one fountain discharge outlet to trickle or drizzle back into the water supply pool.
