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.

There are two ways to get a payment receipt:  (1) Enter an email address on the Payment Information screen to receive a receipt via email.  (2) Click on Print Receipt after the transaction is completed successfully.

Email confirmations are only generated if you enter an email address on the Payment Information screen.  The receipt will go to the email address that you provide in that field.  If you entered a correct email address and did not receive a receipt, contact Wastewater Management Division Customer Service at 303-446-3500 or
