Water and Sewer Service

    Gov. Larry Hogan has issued an emergency order that prohibits electric, gas, water, sewage, phone, cable TV and internet service provider companies from shutting off any residential customer’s service, or charging any residential late fees during the COVID-19 emergency.

    If you’ve recently received a shut-off notice from the City of Rockville, you can disregard it. The city will not be shutting off water and sewer service if you did not meet the payment deadline by March 15. Any utility bills issued after Feb. 15 will not be assessed late fees while the governor’s emergency order is in effect.

    Residents are encouraged to pay bills online. 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).
