What causes discolored or cloudy water?

Water may come become discolored with a brown tint or cloudy due to a number of things happening in the water distribution system.  There can be several reasons why you experience discoloration, such as:

  • Hydrant flushing
  • Watermain gate valve operations
  • Repairs of a watermain break
  • Plumber working on your house or neighbors
  • Builder connecting watermains for new construction

This type of work could stir up sediment that has collected in the watermain and happened to flow through the system into your home.  Although it is not harmful, it may cause stains in your laundry.

First, we always recommend that you contact the Public Works Department at 763-785-6165.  Staff will be able to answer your questions and provide assistance.  It also helps us hear about potential problem areas in your neighborhood so we can respond if necessary.
