Lake HIGH PRESSURE ZONE AREA Lake Lucy Lakke Ann HWY 5 WATER PRESSURE ZONE AREAS HIGHLow LOW Chanhassen's Newest Water Treatment Plant is Complete and Operational The new water treatment plant located at the corner of Lake Harrison Road and Galpin Boulevard is now in service. The treatment plant is designed to remove troublesome Iron and Manganese that naturally occur in deep well water. The most common result of these elements is brown or rusty colored water. Please Check Your Water Softener Setting Residents in the High Pressure Zone Area that are now receiving water from the new plant may notice some subtle changes in water aesthetics. Some attention should be given to the water softener setting. The groundwater in the Chanhassen area contains approximately 21 grains per gallon of hardness. The water treatment plant may allow your home softener an easier time treating the hardness, so a setting of more than 21 grains per gallon may not be necessary If you have any questions about your home softener setting contact your water softener company or contact Chanhassen Public Works at 952.227.1300.
