The City of Orono maintains a municipal water system consisting of 34 miles of water main, two treatment plants, four wells, 278 Hydrants and 266 Valves. The water system is divided into three main zones: the north zone around the highway 12 corridor, the Navarre zone in Navarre and a eastern zone that is connected to the Wayzata system..
Water to residents is an important and fundamental service City of Orono provides. Each year, the city sends a water system report to all residents. It provides information about the city’s tap water and how it compares to standards set by the Environmental Protection Agency.
City of Orono water is tested by an independent, state-certified laboratory and the results are submitted to the Minnesota Department of Health. Public water supplies are regularly tested for more than 100 contaminants that can cause health concerns, such as bacteria, nitrate, pesticides, solvents and metals.
Water plant operators also test water multiple times per day for appropriate chemical levels and water quality.
The City of Orono works every day to provide safe and high quality drinking water service to residents and businesses. Before distribution, the city treats water by disinfecting and it improves the quality by removing iron, manganese and minerals that can affect the taste and cause staining.
Water Main Breaks
If you see water bubbling to the surface along a roadway, it may be a water main break. If you suspect a water main break, please call 952-249-4600 . After regular business hours, call the public safety dispatcher at 952-258-5321.
The city will investigate the problem and determine if there is a leak in either the public or private service line to the building. If there is a leak in the private service line, the city will notify the property owner to correct the problem. If the leak is in the city’s system, the city will have it repaired.
Water Main Flushing
To help maintain a high level of water quality, the City of Orono typically flushes water mains in the spring. During water main flushing, your water could be rusty and you may notice a reduction in water pressure. These conditions are more likely on the day crews are flushing mains in your neighborhood. Avoid doing laundry on that day. If you notice discolored water, let your outdoor water faucet run until the water is clear. Water main flushing schedules are publicized in the city newsletter, local newspapers and on this city website.
