Report a sewer drain issue

Last updated June 19, 2025

Water overflowing from a sewer drain? Cover missing or not on properly? Has something fallen through the grate? Let us know. We’ll take care of it.

Help us respond quickly and effectively by reporting an issue with a sewer drain on the street or sidewalk or in a park.

If possible, provide a photo of the area around the sewer drain (no close-ups, please) to help our teams find the exact location using visual cues.

If the situation is potentially dangerous or requires immediate response, contact 311.

If your report involves a hole around a manhole cover, please visit the “Report a pothole” page instead.
