Low Flow Diversion

A low flow diversion is a structure that captures dry-weather urban runoff and routes it into a sanitary sewer for treatment and discharge offshore. The purpose of a low-flow diversion is to protect beachgoers, swimmers, etc, from coming in contact with polluted urban runoff that has been related to illnesses.

Low flow diversions are not intended to handle wet-weather stormwater runoff.

Currently, there is one low-flow diversion project, the Thornton Avenue Storm Drain, under operation within the City of Los Angeles near Venice Beach.

There are currently plans to build several more structures pending City Council approval.
