Chanhassen's water hardness is 21 grains per gallon.

Call (952) 227-1300 and set up an appointment for a water shut-off.

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.

Please find our current Water Quality Report on the Sewer and Water page.

Our water is disinfected with a small amount of chlorine to guard against disease causing organisms, and pathogens.

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.

Contact Water Production Foreman, Jacob Casebeer, by email or by phone at 952-227-1701.

These spots are caused by deposited calcium hardness. This is a typical sign of a malfunctioning home water softener or the absence of one.

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.

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.

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.
