The sewer utility is comprised of both the storm and sanitary sewer utility. Please choose the tab on the left for detailed information about each one. Utility rates are not part of your taxes but are a user charge most commonly described as your "water bill". This bill includes the rate for local sewer, MMSD sewer, storm water, public fire, and the obvious water/water meter. Below is the breakdown for the storm and sanitary sewer rates that you see on your water bill.
