Question Details:They charge for sewer that I'm not using. If my water bill is $30, they charge $30 for sewer . If my water is $20 , my sewer is $20 ,They have no way of knowing the amount I use and was told. That is how they do it because there is no way to monitor how much I use, with all my dogs and plants; I know I am not using their sewer as much as my water.
The best way to have your question answered is to contact your local water company and go over the way that you and other customers are charged for your water and sewer bills.That is how your question will be answered in the most detailed and concise manner.
My experience is that one's water and sewer bill with a given water company is simply based upon the amount of water use a particular customer has on a given month.
