Water Quality Projects

The last three years have seen a dramatic increase in efforts to curb the impacts of urban runoff through collaborative planning processes and regulatory and legislative mandates. OC Flood has made a commitment to do its part to improve water quality in the region. The Division uses a variety of best management practices (BMPs) in its flood control system to improve water quality. Low flow diversion systems are used in its channels to divert water pollutants to the sanitary sewer system for treatment. Trash booms are used to trap floating items before they reach Orange County's beaches. OC Flood coordinates with OC Watersheds which implements water quality and watershed planning, and coastal resources management.
