Donald Trump on Tuesday signed a bipartisan bill to improve the nation’s water infrastructure, including a Florida project intended to reduce toxic algae blooms in south Florida.

The new law will help create a reservoir south of Lake Okeechobee designed to filter out toxins that contribute to harmful algae blooms.

The America’s Water Infrastructure Act of 2018 authorizes more than $6 billion in spending over 10 years for projects nationwide, including the $1.3 billion Everglades Agricultural Area reservoir.

The law also boosts projects to restore Gulf Coast wetlands damaged by Hurricane Harvey and sets up a new framework intended to increase local input on large water projects run by the U.S. Army Corps of Engineers.

The bill passed the Senate 99-1, with Utah Republican Mike Lee the lone dissenter.
