Use DC Water's emergency channel
DC Water directs water emergencies and sewer backups to 202-612-3400. Its flood guidance also accepts storm drains needing cleaning or repair through that number or online, with a command center staffed continuously. Give the property address and distinguish street ponding from water inside the building.
Do not equate drainage with sewer protection
DC Water describes backwater valves as devices on sewer laterals that allow flow outward and block returning wastewater. They do not stop every route of outdoor water entry. After safe drying, choose prevention based on the observed pathway rather than assuming a valve solves all flooding.

Choose the right report before repair
DC Water handles water emergencies and sewer backups by phone, and also accepts storm-drain cleaning or repair requests. Give the address and distinguish street ponding from water inside. A backwater valve blocks wastewater returning through the sewer lateral but does not stop every outdoor water pathway. Select prevention based on the documented entry route after safe drying rather than assuming one device resolves all flooding.
