Pollution Prevention

All outside drains are part of the storm drain system which carry flows directly to the nearest creek. These creeks are more than flood control channels and can include fish and wildlife habitat, recreational areas and drinking water supplies. Flows to the storm drain system (street gutters, inlets, pipes, and creeks) are not treated to remove pollutants like the sanitary sewer system does with waste water from our homes and work facilities. Storm drain flows are runoff from rain, irrigation and other sources. Any material that has been deposited on the ground or street is picked up and carried to the storm drain system. This material is what pollutes the runoff and our waterways. 

Pollution sources are many and varied:

  • sediment from grading operations
  • concrete by-products from construction projects
  • sanitary waste and pathogens from temporary restrooms and pet waste
  • debris from discarded building material
  • soil and grease from cars and equipment
  • paint, chemicals and solvents
  • fertilizers, pesticides and herbicides
  • yard clippings
  • soapy water from car washing
  • dirty wash water
  • used cigarettes and other litter

To help protect and enhance the water quality of our watercourses, Sonoma County developed a Storm Water Ordinance which prohibits the release of polluted storm water to the County's storm drain system.
