Water Pollution Control

The Water Pollution Control Division is responsible for the regulation, collection, treatment, and disposal of wastewater from all residential and commercial sources within the City's sewer service area. It is our mission to responsibly, cost-effectively and professionally:

  • Collect and biologically treat wastewaters
  • Recycle biosolids
  • Protect San Francisco Bay water quality
  • Supplement the local limited water supply with recycled water
  • Protect the environment
  • Educate and create partnerships with the public

The Water Pollution Control Division provides operation and maintenance of the Water Pollution Control Plant, 125 miles of sanitary sewer pipelines, 13 remote sewage pump stations and the inspection and maintenance of the City's storm water collection system.

The Division also provides contract operation, maintenance, and laboratory services to the East Bay Dischargers Authority and environmental oversight of hazardous materials, wastewater pretreatment pollution prevention, and storm water permitting. The Plant serves the approximately 50,000 residents and the businesses in the northern two-thirds of San Leandro.

Report a Sewer Overflow

Sewer spills have many causes and may look like wet ground around the manhole in the street, leaking water from cleanouts or unusually odorous wet areas. If you have a sewer spill, immediately call the Treatment Plant at 510-577-3434. If there is no answer, please call the San Leandro Police Department at 510-577-2740. Our crews will locate the blockage and determine whether it is in the public sewer; if it is, the crew will remove the blockage and arrange for cleanup.
