Water and Sewer Service

    Any water and sewer bill issued after Jan. 1, 2022 will be subject to late fees and service interruption for delinquent accounts. A penalty charge will be assessed on unpaid bills 30 days or more past their due day. Service will be stopped on any accounts that are delinquent 60 days after the bill date. Any unpaid balances before Jan. 1 are not subject to these terms.

    Also effective Jan. 1, 2022, all applicants for financial assistance must have a notice of pending disconnection or have already had their service disconnected, and must apply with the Montgomery County Department of Health and Human Services. Montgomery County DHHS will submit a referral to the City of Rockville Community Services Division on behalf of eligible city residents.

    Due to COVID-19, applications for financial assistance with water utility shutoffs are being processed by phone and email.

    Residents are encouraged to pay bills online. If you need assistance, please email Utility Billing.
