Chaska's Municipal Water System

Chaska has 6 ground water wells that pump water from wells that are 330 ft to 817 ft deep. Water is drawn from the following aquifers: Mt. Simon, Hinkley, Franconia, Ironton, Galesville, Jordan, and Glacial Drift aquifers. Chaska has recently completed the construction of the new Water Treatment Plant that is capable of treating 12.6 million gallons per day, for iron and manganese removal to only trace levels by gravity filtration. Sodium hypochlorite is used to disinfect the water for bacteria and fluoride is added to enhance tooth protection, as required by state law. Water is pumped to the distribution system after treatment and is stored in 4 elevated towers that have the capacity to hold 4 million gallons.
