Common Service Problems
  • Check your toilets for leaks - Put a little food coloring in your toilet tank. If, without flushing the color begins to appear in the bowl within 30 minutes, you have a leak that should be repaired immediately. Most replacement parts are inexpensive and easy to install.
  • Check your water meter for hidden leaks - Read the house water meter before and after a 2-hour period when no water is being used. If the meter does not read exactly the same, there is a leak.
  • Check your faucets and pipes for leaks - A small drip from a worn faucet washer can waste 20 gallons of water per day. Larger leaks can waste hundreds of gallons.
Water Conservation Notice
As part of the State Mandated Water Conservation Plan and in order to insure adequate water supply for water protection, the Chaska Water Department has implemented an odd-even lawn-watering program. This program greatly reduces the city's peak water demand during the heavy usage months between May 1 - September 30.

The City of Chaska Water Department requires residents to comply with this program. You are required to limit your lawn sprinkling and other non-essential water use based on your address and the calendar day of the month. If your address is an odd number, you must limit your lawn sprinkling to odd number calendar days. Likewise, your neighbor with an even numbered address must limit their lawn sprinkling to even number days.

Compliance with this ordinance is mandatory. Failure to comply may result in a $100 fine and/or termination of water service. New seed or sod that is not established is exempt from this ordinance for a 14 day period. Thank you for your cooperation.

If you have any questions or concerns regarding this ordinance, please feel free to call the Water Department at 952-448-4335.
