Water & Sewer

Areas of Dayton have begun the transition from private water and sewer systems to city services. As more businesses and residents hook up to these utilities, we have been inspecting the work of the contractors to ensure old septic tanks have been properly abandoned. As part of the utility hook ups, MXU devices are being installed to make reading water meters less invasive for property owners, and to cut costs for staff. The water and sewer department monitors the City’s infrastructure and provides maintenance. Some maintenance most noticeable to the public is the routine flushing of fire hydrants which happens in April and October each year.

Odd/Even Irrigation Restrictions

The mandatory odd/even irrigation ordinance has been adopted by the City Council. The ordinance will be effective from July 23, 2020 through October 31, 2020. The ordinance is designed to restrict the use of lawn irrigation by implementing an odd/even system. The ordinance prohibits watering of lawns, trees or shrubs between the hours of 10:00 a.m. and 7:00 p.m.

  • Properties with even numbered post office addresses may irrigate on even numbered calendar days.
  • Properties with odd numbered post office addresses may irrigate on odd numbered calendar days.
  • The day begins at midnight and ends at midnight.
  • Irrigation is not permitted between 10:00 a.m. and 7:00 p.m.


You live at 12001 Dayton Lane, you may irrigate on June 1 starting at midnight up until 10:00 a.m. If you prefer watering in the evening you may irrigate beginning starting at 7:00 p.m. up until midnight.

  • Properties with private wells are exempt from the irrigation restrictions.
  • New sod installation is exempt for 4 weeks.

Water Quality Reporting Forms

There are two forms, an initial questionnaire which needs to be filled out on the first contact which is designed to gather specific information about the home and types of treatment the home has. The water quality tracking form should be used for every subsequent reporting of water quality issues. If you have questions please contact Public Works on 763-427-3224.

Water Conservation
  • Summer generates an increase in water usage; this is due primarily to irrigation of lawns. The majority of new homes have an automatic sprinkler system and these systems are set up initially by the builder to run frequently to establish newly installed sod. Once the turf is established the irrigation system should be adjusted to water less frequently. To maintain a lawn takes approximately 1” of water per week during the summer, which equates to resetting the irrigation system to run 3 times a week for 20 minutes.
  • The City of Dayton has a tiered water billing system, the more water you use the more you are billed. Water used at the home is monitored by a meter that is installed where the water enters the home. Water entering the home is billable no matter what it is used for, so the water used for lawn maintenance is billed in the same way the water used for the laundry or showering is billed. A home with an automatic sprinkler system and an average winter bill of $86 may increase to $228 a billing cycle during peak use due to an unadjusted sprinkler system.
  • Reducing residential watering can save you money and help the City manage future infrastructure costs so improvements do not have to be made prematurely. In addition to preserving water outside, there are ways to conserve water within the household. Some of these things are simple such as turning off the faucet while brushing teeth, taking showers instead of baths, and using only full loads of laundry to be washed so that no water is wasted. Household water leaks may also occur, so make sure those repairs are completed as soon as possible.
