This is pretty great: today, D.C. Water — never an agency to shy away from fun ways of interacting with its customers — released “A Drop’s Life,” an “informational cartoon” to explain to the public the Clean Rivers Project, a 20-year, $2.6 billion program that’s supposed to “reduce combined-sewer runoff to the Anacostia and Potomac Rivers and Rock Creek by 96 percent.” (D.C. Water General Manager George S. Hawkins calls the project “the biggest thing we’ve ever done.”) We’re wholly in favor of this whole “using cartoons to explain large public works projects” idea — though since the agency is slated to take a $14 million hit as part of the spending cut accord reached by Congress, we probably shouldn’t get too used to it.
