Water, Sewer & Stormwater

    At this time and until further notice, past due bills are not being charged a late fee and the City is not shutting off water and sewer service for delinquent accounts.

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

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.
