The McCook Public Water System (license # NE3114504) receives its water from a series of wells located in the Republican River Valley. The well field consists of 9 wells. Each well pumps water to the Water Treatment Plant (WTP) which is centrally located to the well field. The WTP came online in February of 2006 and uses ion-exchange to soften the water to 17 grains of hardness and remove arsenic, nitrate and uranium to suitable levels. The WTP has a daily capacity of 6.5 million gallons.
