Is There a Difference Between a Storm Drain and a Sewer Drain?
Yes. The sewer system and the storm drain system are two completely separate drainage systems. The sewer system, or sanitary wastewater system, takes all household wastewater from toilets, showers and sinks, and routes it through your plumbing system into the City of Los Angeles’ Hyperion Treatment Plant. Once there, it receives 3 levels of filtration treatment before being discharged 5 miles out into the ocean. The stormwater system, was intended to route rainwater quickly off the streets during a heavy storm, but unfortunately takes all urban runoff along with it. Chemicals, trash and debris from lawns, parking lots and streets, either intentionally or accidentally spilled, goes straight into the ocean.
