The discharge of pollutants to the storm drain system is the leading source of water pollution in local creeks and San Francisco Bay. To maintain the health of the Bay, federal and state laws require Bay Area cities to reduce pollution.
Through the implementation of its Clean Water Program, the City is committed to performing necessary services and providing residents and businesses with practical solutions to help reduce pollution. We need everyone's help. If you see a spill or illegal dumping, report it!
The Clean Water Program uses a multi-faceted approach to prevent stormwater pollution. Program elements include:
Public Outreach and Education
New Development Design Review
Industrial and Commercial Facility Inspections
Construction Site Inspections
Illicit Discharge Inspections and Response/Enforcement
Trash Load Reduction
Heavy Metals and Legacy Pollutant Controls
Storm Drain System Cleaning and Maintenance
Storm Drain System Improvements and Upgrades (e.g. pump stations, storm mains)
Participation in the Alameda County Clean Water Program
Contributions to a Regional Water Quality Monitoring Program
Anything other that rainwater that enters storm drains may be harmful to people and the environment.
So remember: only rain down the storm drain!
We are required to implement its Clean Water Program as a condition of the National Pollutant Discharge Elimination System (NPDES) permit for the City’s storm drain system. The conditions of this permit direct municipal compliance with the Federal Clean Water Act to protect the quality of local stormwater runoff. The City implements the permit requirements with all other Alameda County local agencies as a co-permittee in the Alameda County Clean Water Program.
Stormwater pollution is water runoff that becomes polluted as it runs over land. It's harmful to fish, wildlife, and human health. It can lead to loss of recreational uses and loss of biological and aesthetic value.
Pollution occurs when water from rainfall, garden hoses and sprinklers picks up oils, litter, pesticides and other substances from city streets, gutters and sidewalks. The contaminated water enters the storm drain system, and from there, is carried untreated to the Bay and Estuary.
Many stormwater pollutants are invisible. But, if you see an oily sheen or turbidity on water flowing off paved surfaces, you've have seen an example of stormwater pollution.
Maps of the City of Alameda’s storm drain system are available for viewing at the front desk of the Public Works Department.
