Figure out two things:

1-how much revenue this will generate
2-WHO specifically will be paying what (by class ie industry, residential, ag, etc) and in what proportion

With this info you will see what city hall already knows and you will gain insight into who they really wanted to pay this new tax.

THIS info is what you want to hand to local media if necessary.

I'm curious why they didn't just raise sewer rates. This would seem the obvious thing to do. Perhaps your public services commission (or whatever regulatory agency you have) said 'no' so they had to do an end run around the system. THIS would be key to putting the smack down on this new 'tax'. There is a reason it is worded like it is. Find out why.
