Pre-Payment of Sewer Service Charges

In an effort to assist customers in managing the amount of their annual sewer bill amounts, New Castle County allows you to pay on your account in advance.

Any advance payment made will post to your account as a credit and apply to the next bill generated on your account.  The County accepts “pre-payments” by all accepted payment types listed in the above “Methods of Payment” section.
You may also choose to make pre-payments through an online payment service, possibly through your bank.  If you choose to make payments to us in this manner, you will need to have your account number (for sewer bills, this is referred to as your “parcel number”), and our name and mailing address for payments.

You may get your account/parcel number from your bill or from our website. You may search for your account/parcel number on our website with your property address by clicking HERE.

For example, sewer service bills due February 29, 2016 cover the calendar year ending December 31, 2016. Sewer service bills are based on a property's actual water usage over a prior 12-month period. The property's water company provides this information in quarterly amounts to New Castle County.
