Like most cities, Minnetonka treats its drinking water to improve its quality before it’s delivered to residents and businesses. The city’s water treatment procedure includes:
Disinfection: Chlorine (one drop per gallon) removes microscopic organisms.
Fluoridation: Flouride is added at state-mandated levels to support oral health and reduce tooth decay.
Iron Removal: Iron isn’t a health threat, but we remove it from the water to improve the color, taste and usefulness.
Corrosion Control: We add a corrosion inhibitor, which coats the inside of your plumbing to prevent lead or copper corrosion and contamination.
Hardness: Calcium and magnesium cause “hard water.” Our treatments do not reduce hardness levels. Residents and businesses may choose to use home-softening devices if hardness is an issue.
Flushing: Each spring the city flushes fire hydrants to remove iron and manganese from the system. During flushing, it’s normal to experience some discolored water. This water is safe to drink and can be cleared up by running cold water in your laundry tub. Call 952-988-8400 with questions or to learn more.
Water main breaks
Water mains are susceptible to breaks from ground movement when the ground freezes or thaws. If you see water running out of the ground, through cracks or behind the curb, report the issue to the city immediately.

Frozen water pipes are rare, but this can occur when winter temperatures are exceptionally cold. Follow these tips to prevent and deal with frozen pipes:
- Run cold water continuously from the lowest point in your home. The stream should be about the width of a pencil.
- Open your cabinets to allow heat to reach your pipes.
- Insulate your pipes.
- If your pipes have already frozen, running water continuously is essential. You can also use a hair dryer or space heater to warm frozen pipes.
