The storm drain system moves all of the water from outside homes and businesses (storm water and urban runoff) and carries the untreated water straight to local rivers, wetlands and eventually the ocean.
The sewer system is a network of pipes which moves all of the water from inside homes and businesses (water from sinks, bathtubs, toilets, etc.) to a waste water treatment facility, where the water is cleaned before being released into the ocean.
The sewer system can become clogged, causing sewage to spill out of sewer manholes in the street or sewer clean outs at homes and businesses. The untreated sewage then flows into the street, storm drain system, and eventually the ocean. Sewer spills impact residents, businesses and the environment.
Fats, Oils and Grease or FOG is a leading cause of sewer spills. FOG collects in the pipes sewer system, until it causes a blockage and sewage over flows. Learn more about preventing FOG blockages.
