The idea to serve only water started as a pop-up art project in 2014, a collaboration between artists Shanai Matteson and Colin Kloecker of Works Progress Studio.
The bar intends to serve local tap water to increase awareness about problems concerning water quality.
"Water Bar is an itinerant open space for the generation of conversations and connections around the life-sustaining, precarious, communal activity of drinking tap water," the bar's website states.
"We invite Water Bar visitors to engage with one another, as well as with project collaborators, who tend bar and share their knowledge of water and water issues."
The bar employs the motto "Water is all we have," and allows visitors to sample flights of tap water free of charge, so they can taste the difference between private well water and public tap water.
The project is set to open its first location in its home state of Minnesota in order to combine with an art studio and hopefully extend its reach.
