Gopher State One Call
Under state law, if you are planning to do any work on your property that involves excavation more than six inches deep, you need to contact the Gopher State One Call system 48 hours before you plan to dig. Gopher State One Call will notify any known parties who have underground utilities in the area that a locate has been ordered. The operators are then required by law to mark their utilities with paint or flags within 48 hours. There is no fee for this service. The number for Gopher State One Call system locate is (651)454-0002.
If your yard or boulevard has been marked with paint or small flags, this means that someone is planning to perform work in the area, and has called Gopher State One Call system for a utility locate. If you have questions please contact Gopher One by visiting the Gopher State One Call website.
Private Owned Utilities
When a property owner or tenant has any type of privately-owned underground facility (underground sprinkler systems, invisible fences, pool heaters, etc.), they are responsible to locate those facilities or hire someone to locate them. For more information about locating privately-owned facilities, visit the Gopher State One Call website
If you notice water leaking near the meter, it’s essential to determine the source of the leak by contacting a plumber. If the issue lies with the water meter connections or surrounding plumbing, the responsibility falls on the homeowner. Maintenance, repair and replacement of these elements are the homeowner’s responsibility.
The City will replace the water meter if it is damaged. If you have additional questions or need a staff member to help determine the leak source, please contact Public Works at (763) 427-3224 or email publicworks@daytonmn.gov
Water Shut Off
Please contact Public Works Department at 763-427-3224 or email publicworks@daytonmn.gov to schedule an appointment. We require 48-hour notice unless the repair is an emergency.
After hours emergency, please dial 911.
There are two forms, an initial questionnaire form is designed to gather specific information about the home and types of treatment. The water quality tracking form should be used for every subsequent report of water quality issues. If you have questions, please contact Public Works at publicworks@daytonmn.gov or call (763) 427-3224.Initial Water Quality Questionnaire

Final Odor Study Report PHASE 1
To help maintain a high level of water quality, the City of Dayton flushes hydrants in Fall & Spring. Flushing hydrants also provide a way to verify operation for maintenance or repair. The process of flushing the water system may result in low water pressure, cloudy or discolored water during the days the system is being flushed. Please be aware of the water quality while doing laundry to avoid staining. The discolored water is not dangerous to your health and is safe to drink. Water can be cleared up by running the cold water through out the home.
To find out when your neighborhood will be flushed, please watch for signs in your neighborhood.
Providing water to residents is one of the City of Dayton's most important and fundamental services. Each year, the city will send out a Utility Bill in the Summer with the link to the report. It provides information about the city’s tap water and how it compares to standards set by the Environmental Protection Agency. View the Dayton Drinking Water Report
Wellhead Treatment Plant is fully online!
The City of Dayton is excited to announce that the new Wellhead Water Treatment Plant is fully online! The plant is designed to remove high levels of iron and manganese that are present in the water drawn from the aquifer, that supplies the northeast Dayton water distribution system. The Plant is served by 2 high-capacity wells that can produce up 2,000 gallons of water per minute. The plant is capable of producing nearly 3,000,000 gallons per day at peak capacity. Currently, our peak capacity is around 1,250,000 gallons per day. Staff purposefully managed the transition from the non-filtered water to the filtered water to purge the non-filtered water out of the system and replace it with the treated water. Staff has also rigorously flushed hydrants in the fall and the spring to try and remove the residual mineral deposits in the water mains.
How was this project funded?
A majority of this project was funded from Federal and State grants totaling $5,750,000. The additional 3,000,000 needed to complete the project came from City Water Funds.
Will water pressure change?
There should not be noticeable changes to water pressure from the new plant.
Will water smell or taste different?
The water should be consistently clear, and not have problems with odor, because more of the impurities are being permanently removed at the filtration plant. There should not be a noticeable high chlorine smell. Minnesota Department of Health (MDH) requires the City to feed a low dose of chlorine for disinfection purposes.
Who manages the water quality checks?
Trained City staff will manage a majority of the water quality sampling. We test for a whole panel of different criteria, chlorine, fluoride, ammonia, pH, iron, manganese, sulfate amongst others. There are also specialized tests required by MDH that we send to a certified professional laboratory for analysis. MDH conducts frequent site visits and sampling. The results can be found in the Drinking Water Report available on the City
website under the Water Department.
Drinking Water Report
The Drinking Water Report is a water quality report that provides information about the quality of drinking water. The U.S. Environmental Protection Agency (EPA) requires every community water supplier to provide a Consumer Confidence Report (Drinking Water Report) to its customers. The latest Drinking Water Report for the City of Dayton, Maple Grove, and Champlin is available on the City website. You may request a paper copy by emailing publicworks@daytonmn.gov. If you have questions, please email Martin Farrell at mfarrell@daytonmn.gov.
Like most cities, Dayton 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 is added at state-mandated levels to remove microscopic organisms.
- Fluoridation: Flouride is added to support oral health and reduce tooth decay.
- Hardness: Our treatments do not reduce hardness levels. Residents and businesses may choose to use home-softening devices if hardness is an issue. Please refer to the softener setting below or contact the Public Works Department at (763) 427-3224 if you have additional questions.
North West System (Historic Village)
- Iron content .5 parts per million
- Hardness 30 grains
- Softener setting should be 35
North East System
- Iron content .5 parts per million
- Hardness 38 grains
- Softener setting should be 20-22
South System (Maple Grove)
- 19-22 grains
- 370 parts per million
- Softener setting should be at 40.5
Water Quality Testing
The City tests water daily to verify the water meets all healthy and safety standards. If you would like the water tested at your property, please contact publicworks@daytonmn.gov or (763)427-3224 to schedule an appointment.

Make an Impact Indoors
You can find ways to conserve water inside your home to save money on your water bill annually. Here are some tips for conducting in-home audits:
- Take shorter showers and use a timer. Replace showerhead with and efficient showerhead.
- Old toilets use more water to flush. To save water, purchase a toilet with the WaterSense label and dual flush.
