Welcome to Harris County Water Works Online Bill Pay Service (excludes Hamilton). You must include your CUSTOMER NUMBER before you submit your payment. All bills paid on line will be assessed a $3.00 non-refundable convenience charge at time of submission of payment. Payments are credited the next business day. If paid after the due date, 10% of the balance due will be charged to your account as a late penalty.


When making payment, you may get an  OOPS or Error message... If you get this message, exit out of the system completely, DO NOT click the back button or refresh button. Try using Google Chrome as your browser. Also, if you are not sure the payment was accepted, DO NOT enter information again. Check your card statement/account the next day to see if the payment was processed.  If you are still not sure the payment was processed you may call our office 706-324-1175 to see if we received your payment. We are having to credit duplicate payments multiple times due to this issue.
