I’m thinking that’s what’s about. Many municipalities charge sewer rates based on water usage.
She has some sort of on-property septic system.
I too am thinking this is why the city is screaming foul ... Could be wrong though.
True, but most municipal water systems also have flat rate for customers that have another source of water, such as a well, but are connected to the POTW (sewer system) Also, some communities put a fire protection charge on the water bill. This is for maintainance of the fire hydrant system. If Cape Coral has such a charge then the woman would not be paying her fair share of fire hydrant maintenance costs yet she is getting the benefit. Don’t know for sure but that’s the way it works where I live.
