Water Meter Repairs
Water meters measure the amount of water used by individuals and/or businesses. Occasionally the City may need to gain access to your home to repair the water meter. You will receive a letter in the mail asking for you to call the Public Works Department at 651-458-2808 to schedule an appointment.
A uniformed City employee will arrive at your home in a City marked vehicle to make this repair at the scheduled time. The City is responsible for the repair of the water meter in your home if it is not caused by the negligence of the homeowner. If you have a meter that is leaking or not functioning properly, call Public Works at 651-458-2808 24 hours a day, 7 days a week.
Water Meter Turn-On & Turn-Off Procedures
If you need the water turned off at the curb call the Public Works Department at 651-458-2808 to schedule an appointment. Please have a lock-box code or be prepared to meet the Utility employee at the time of the shut-off. There is a $75 fee for a turn-off and $25 fee for a turn-on service that will be added to the utility bill. Water shut-off and turn-on services can take up to four days so plan accordingly. The following forms must be completed before the service.

Hydrant flushing will begin weather permitting the week of April 12, 2021. See Flushing Map here.
To protect the City's water supply, all Cottage Grove water mains will be flushed twice a year. Once in the fall and once in the spring. Notification of the flushing will be posted on the City's website and on Facebook. The crews begin in Zone One and finish in Zone Four. Please check the map (JPG) to see what zone you reside in.
This process often causes discoloration of your water. The water is safe to drink but could stain laundry. Check for discoloration before using your washer. The Public Works Department also suggests you flush out the taps in your home, as iron deposits tend to build up in the residential lines. Once hydrants have been flushed, open the outside faucets and run all the cold water taps in your home until the water runs clear. This can sometimes take 10 to 30 minutes.
Odd/even and time of day watering restrictions in effect. Residents may water lawns and/or gardens every other day, based on the last digit of your house number. If the house number ends in an even number (0,2,4,6,8), water on even-numbered days. If the house number ends on an odd number (1,3,5,7,9), water on odd-numbered days.
No watering is allowed on the 31st of the month. No watering is allowed any day between noon and 4 pm Violations shall constitute a misdemeanor and are punishable by a fine or imprisonment or both. If you have new seed or sod you can obtain a temporary permit that allows you to water outside of your schedule by contacting Public Works.
