In light of the recent report about medical drugs in our water (http://www.cnn.com/2008/HEALTH/03/10/pharma.water1.ap/?iref=hpmostpop), and the fact that Cleveland sewage flows into Lake Erie, our water supply, here's an interesting article about how Milwaukee treats their lake water with ozone.  Someone at Cleveland Water should look into this.

Milwaukee is definitely a city with a lot of experience in dealing with water pollution.  Lake Michigan gets progressively more disgusting the closer you get to Chicago. Having two cities so close lying directly on the lake is a real stress on the environment. There's a lot of density around that area to cause pollution, and it takes strong ideas like this to keep the situation livable.
