Billing Issues

We are here to help resolve your billing issues.  If you disagree with your water and/or sewer bill, please contact us at 301-206-4001, toll free 1-800-634-8400, or contact us online.  A supervisor will review your billing and if you do not agree with the outcome, there are two methods to further appeal your bill.

• A Dispute Resolving Board review is a courtesy process allowing customers to dispute their unpaid charges (Dispute Resolution)
• A Refund Hearing, by law, is exclusively for disputing paid charges (Requesting a Refund Hearing).

If you have a billing dispute and we are unable to resolve it, please carefully review these sections to determine the appropriate forum.
