For all matters concerning sewer service in Port Costa, the correct number to call is always (510) 787-2992.

Our staff will respond quickly to all inquiries, complaints or reports of sewer problems. If no one is in the office when you call, a recording will give you an alternate emergency number for reporting a sewer overflow that day. That number will change from day-to-day, so be sure to always call 787-2992 first. Calling any other number will only slow down or prevent a response. NEVER use email to report a sewer overflow or to seek fast assistance!
