Reporting Spills, Dumping, And Back-Ups In Palo Alto
The following information is for Palo Alto residents only
Call to Report Hazardous Spills
If you notice any unusual substance in or around a storm drain, or if you see someone dumping anything into a storm drain, don't wait! Call the City of Palo Alto 24-hour communications line at 650-329-2413 immediately.
Call the City at 650-329-2413 if you see any spill of a potentially hazardous material in or around a street, or gutter, in or around local creeks or the Bay, or elsewhere in the outdoor environment.
If you find out that hazardous materials have been dumped in the sewer system, call the Regional Water Quality Control Plant at 650-329-2598
Call if a Sewer Line is Blocked
Call the Utilities Emergency Line: 650-329-2579
Note: If your drains back up because roots are clogging the sewer line, use mechanical root removal, not crystal-form root killers you flush down the toilet. Mechanical root removal is the most environmentally sound method of controlling roots in sewer pipes. Use of crystal-form, copper-based root killers have been banned in the Bay Area. They are also not as effective as mechanical removal, and they contribute significant amounts of copper (which is toxic to marine life) to the Bay's sensitive ecosystem.
Call for a Clogged Storm Drain
In an emergency (flooding imminent)-call the Utilities Emergency Line at 650-329-2579
If it's not an emergency, call Storm Drain Maintenance at 650-496-6974
