Why is my water sometimes rusty looking?
There are some areas in the city where water use is low and trace elements in the water have time to settle out of solution and collect in the bottom of the pipe. These can then be stirred up by sudden high use. It is not harmful to drink but should be removed by contacting Water Production Foreman, Jacob Casebeer by email or by phone at (952) 227-1701.
What is my water’s hardness?
Chanhassen's water hardness is 21 grains per gallon.
How do I turn off the water supply to my house in the event of a scheduled plumbing repair?
Call (952) 227-1300 and set up an appointment for a water shut-off.
Is the City responsible for plumbing leaks?
The city is responsible for maintaining only the water meter inside the home. It is the responsibility of the homeowner to maintain the service line to the structure being served, including the curb box. The city is responsible for the water main, service connection, and service line up to (but not including) the curb box.
What is my drinking water quality?
Please find our current Water Quality Report on the Sewer and Water page.
Why is chlorine added to our water?

Why is fluoride added to the water?
Fluoride is added to the water as mandated by the Minnesota Dept of Health to protect children’s teeth. It is added at a dose of about 0.7 part per million.

Where can I find my water meter and how can I use it to check for leaks?

What causes the spots on my dishes?
These spots are caused by deposited calcium hardness. This is a typical sign of a malfunctioning home water softener or the absence of one.
Why does the water sometimes look milky?
Milky looking water is an indication that there is air in the water. This is not harmful and is usually caused by recent water main work or repair in your area. Notify Public Works of the problem, so they can remove the air with hydrant flushing. Contact Public Works at (952) 227-1300.
What is the small metal disk in my yard or driveway?
This is the water shut-off valve to your home. Seasonal settling can cause the valve (sometimes referred to as a curb box) to stick up above the surrounding ground and become a problem for lawn mowing or driving if it is in your driveway. Please contact the Utility Department at (952) 227-1300.
Why does my water smell like rotten eggs and how do I get rid of it?
Smelly water, or rotten egg odor, is hydrogen sulfide gas that is present in the water. It is not usually harmful at the low concentration that occurs in a household water system. The City maintains a chlorine residual throughout the system that eliminates this smell, but if water sits in any place too long (dead-end lines, unoccupied houses, new developments with only a few homes), the chlorine dissipates and results in the smell. Water heaters with a magnesium anode rode are another common cause of this odor, especially in houses where little water is used.

To eliminate smelly water caused by your water heater, turn your hot water heater up to high for several hours (150-160 degrees). This should kill the sulfur bacteria. Then flush your system, especially your water heater. Also, the magnesium rod can be replaced with an aluminum one, or removed completely. If you live on a dead-end line or in an area with just a few homes, we recommend calling the City Water Department at (952) 227-1300 so that the lines can be flushed to assure that there is chlorine present to kill the hydrogen sulfide odor.
