Hyrdoelectric power generators in the sewer systems

Hydroelectric power generators can come in any size really. Obviously the Hoover Dam isn't going to fit underneath a city, but what about several small generators placed strategically throughout our sewer systems that can use the flow of water runoff to generate power. It won't be enough to power a whole city, but it could be enough to run some street lights. Every little bit helps.
