Bruce, you have a good point. I should not have made that statement without numbers to back up "many." I'm searching for data.
Edit:
I just called NYSERDA (New York State Energy Research and Development Authority), who are just in the process of completing a survey of waste water treatment in that state. In NY, about 140 treatment plants use anaerobic digestion to treat waste and about 10% of those are generating electricity from the gas produced. I'm awaiting a call back so I can find out how much electricity is being produced and what the others are doing with the AD gas. I'm also trying to find a national source, so I don't have to call every state's energy department.
