Yes, I do believe they are good, and very useful as long as they are properly maintained with access. Definitely if someone is the low guy on the street they need one. just makes someone else the low guy and they need one to and so on and so on. $$$$ if you can sell them to everyone.
But regardless everyone's sewer will back up atleast with a back flow preventer they can control how much they flood and can stop usage. The City line on the other hand can keep on coming up big mess
Charging less does not mean more call volume it just means you have to work harder to reach your goals.
