An auxiliary water reservoir system is disclosed for coupling with an ice making apparatus. The auxiliary water reservoir system comprises an auxiliary water reservoir. An auxiliary water supply conduit supplies water to the auxiliary water reservoir. A return conduit couples with the ice making apparatus and positions an excess water within the auxiliary water reservoir. An auxiliary water pump and auxiliary pump conduit positions the water and the excess water from the auxiliary water reservoir to the ice making apparatus. An auxiliary system controller is electronically coupled to a water inlet regulator and a water level sensor for maintaining a water level within the auxiliary water reservoir. The auxiliary water pump propels the water to the ice making apparatus for utilizing the water and the excess water.
