Thirty-one states have water supplies dipping below normal. Droughts have formally been declared in 22 of them. How we use water has never been more important, especially in the American Southwest, where drought conditions are the most severe in a generation — and could last another 1,000 years.

The vast majority of the water we use goes toward generating power (41 percent) and nourishing agriculture (37 percent). But one in 12 gallons of water is consumed at home.

That’s a small but critically important slice of the water used to make the nation tick. And it’s a slice that every single person in the United States can directly control.

As part of a two-year project examining America’s water crisis, ProPublica is teaming up with CUNY’s Graduate School of Journalism to gather data on how Americans use and consume water at home. We’d like to know what you use. Grab your water bill. Complete the survey below. We’ll tell you how you stack up to your neighbors.
