The storm drain system is for the control of flooding only and the water that enters the drains is not treated before emptying into local creeks that flow to South San Francisco Bay. Regulating pollutants entering the storm drain system is an important function of the Industrial Waste Inspectors in the Pretreatment Program. They do this by inspecting industrial and commercial facilities to identify illegal discharges or conditions that could allow pollutants to enter storm drains. The inspectors educate business operators about the requirement to implement appropriate Best Management Practices (BMP's) (pdf) to reduce or eliminate pollutants entering storm drains.
The Industrial Waste Inspectors also respond to reports of spills or dumping into the storm drain system, provide education regarding the separation of storm drains and sewer systems, and take enforcement action in cases of noncompliance with regulations.
