To find out when your specific area will be flushed, call 763-509-5950 or check the 2025 Spring Water Main Flushing (PDF).
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.
