First lady Michelle Obama and actress Eva Longoria will be in Watertown for an event at the Watertown High School on Thursday.
The White House says the new effort will bring together leaders from industry, entertainment, media and government to promote the health benefits of drinking water.
Watertown Mayor John David said the event is part of Obama's fitness initiative with Partnership for a Healthier America and will promote drinking water instead of soda.
David said he thinks the 24,000-population city, located roughly in between Madison and Milwaukee, was selected because it has the word "water" in its name. And, David said, "We've actually got tremendous drinking water."
But Watertown is also home to Wis-Pak, one of the country's largest manufacturers and distributors of Pepsi products. A company spokeswoman was not immediately available.
The White House announced the event on Monday. It is not open to the general public.
