This entertaining story - told through the eyes of a rain drop falling on Washington, DC - explains how the city's combined sewer system works. It also describes what we're doing to upgrade that system with the DC Clean Rivers Project. We have also just released a follow-up video - A Drop's Life, The Sequel - which explains how green infrastructure works.

A Drop's Life - The Sequel

The sequel picks up the story with a new twist - new green methods to keep that drop and its buddies out of the sewers altogether. It's a story with a happy ending.
