Water, Sewer & Stormwater

  1. Water Problems?
    For emergency water or sewer problems, call the 24-hour emergency hotline at 240-314-8567.
  2. Any water and sewer bill issued after Jan. 1, 2023 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, 2023, 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 at invoicecloud.com/rockvillemd. If you need assistance, please email utilitybilling@rockvillemd.gov.

The City of Rockville provides water and sewer service to 70 percent of the city or about 12,000 accounts. All other Rockville residents and businesses are serviced through the Washington Suburban Sanitary Commission (WSSC).

Every Rockville resident pays a stormwater utility fee which funds the city's actions to help reduce flooding, protect private property, protect the environment and contribute to happier, healthier communities.


If you are experiencing a water, sewer or stormwater problem, including discolored water or a leak, contact the 24-hour emergency line at 240-314-8567.
