Lake Mills Light & Water obtains it's drinking water from a series of three (3) ground water wells located throughout the city. These wells draw from a sandstone aquifer approximately 800 to 900 feet deep. They utilize a state of the art ozone purification process to remove any harmful bacteria from the raw water.

Please remember to trim your shrubs and trees around your water meter. Your meter reader needs to be able to access your electric and water meters each month, so keep your meters free of branches from trees and shrubs or other plantings.

Meter readings will be much more accurate and timely if the meter reader can reach the meters safely and easily.
