A Note About Sewer Billing

As of August, 2012, customers with multiple units serviced by a single meter will now see two line-items on their bill where previously there was only one. The two items are the Sewer Rate and the Base Sewer Fee. Previous bills had these two items combined into a single charge. These fees are calculated as follows:

  • Sewer Rate = Base Meter Fee + Charges for water per Unit
  • Base Sewer Fee = Number of Units X Additional Unit Fee
