Most City residents receive water service.  A number of Forest Lake properties instead draw water from private wells and are not connected to the municipal water system. 

The City of Forest Lake Water Department supplies safe, healthful, and affordable water to residents and commercial businesses.  The City-owned and operated system draws water from the Mt. Simon aquifer using 5 well pumps.  These pumps send water to one of the City’s three Water Treatment Plants for processing.  At the plants, water is chlorinated and fluoridated to meet Minnesota Department of Health standards.  The City’s water is also softened at the plant before distribution.  After treatment, water is pumped to one of the City’s two water towers.  The North and South towers, holding 750,000 and 500,000 gallons respectively, store water for use in our homes and businesses.
