You will not receive another invoice from us until your next six-month billing cycle. We do not send out delinquent notices or interim invoices for remaining balances due between cycles.  

PLEASE NOTE: Non-Payment may result in a lien filed against the property served.

If you opt to pay your bill online, your current balance is always available. 

You should pay any past due amounts as soon as you can. Wastewater Management Division does not charge a late fee. If you fail to pay sanitary sewer or storm drainage charges a service lien can be filed against your property. When a service lien is filed the balance owed is increased by a filing fee and monthly delinquency interest is charged. Service lien delinquencies unpaid as of November of each year are sold at a tax lien sale. The City Treasurer will then file a tax lien against the property. If the tax lien and interest is not settled within three years from the date the tax lien is filed, title to the property may be lost to a Treasurer's Deed.
