Source of Water in Duluth, United States

Duluth’s tap water comes from Lake Superior, which serves as the city’s primary drinking water source. The city draws water through an intake system located offshore in the lake.

The water is treated at Duluth’s Lakewood Water Treatment Plant before entering the municipal distribution system. Treatment removes particles and microorganisms, and the finished water is disinfected to meet Minnesota and federal drinking water standards.

Duluth Drinking Fountains

Public drinking fountains in Duluth are generally safe to use when they are connected to the municipal water system, operating normally, and properly maintained. The water supply is regulated under Minnesota and federal drinking water standards.

Do not use a fountain that is damaged, visibly dirty, has stagnant water, or displays a shutoff notice. During a boil-water advisory or after service interruptions, use bottled or boiled water instead.
