Water Quality Management
Improving Storm Water Quality 
The ocean begins at your front door. Even if you live miles from the Pacific Ocean, you may be polluting it without knowing it. To help prevent water contamination, the City of Placentia has two drainage systems: sanitary sewers and storm drains.

The storm drain system is designed to prevent flooding by carrying excess rainwater away from streets; it is not designed to be a waste disposal system. Unlike the sewer system, which carries water from your indoor drains to wastewater treatment plants, the storm drain system releases untreated water into channels, rivers, and ultimately the ocean.

A little water from rain or a garden hose can carry automotive and household toxic materials through the storm drains to the flood control channel and eventually the ocean. Urban pollutants that can wind up in the street include:
  • Cleaners
  • Construction debris
  • Oil and other automotive fluids
  • Paint
  • Pesticides and fertilizers
  • Yard and pet wastes

Polluted urban runoff contaminates the ocean and beaches, harms aquatic life, and increases the risk of flooding by clogging gutters and catch basins. You can help control water contamination by being aware of the sources and the activities that contribute to stormwater pollution.
