Argo Drain Sub‐Basin Water Infiltration Facility
LAWA and Los Angeles Bureau of Sanitation (BOS) entered into a Memorandum of Understanding documenting potential drainage basin solutions to develop the Argo Drain Sub‐Basin Water Infiltration Facility. The Facility will be located on LAWA property, north of Westchester Parkway, between Falmouth Avenue and Pershing Drive. The Facility will accommodate a watershed area of approximately 2,200 acres. The Argo Drainage Channel will transport storm water via gravity to a detention/retention basin. The flow will be pumped into underground infiltration galleries to recharge the groundwater basin. The Facility will improve water quality in the Santa Monica Bay by diverting polluted water that would flow into the Santa Monica Bay to the infiltration facility. LAWA and the BOS worked in close collaboration to select the appropriate site, obtain funds, and plan for the project. LAWA issued the Concept Approval Letter to the Bureau of Sanitation (BOS) and the Bureau of Engineering (BOE) on December 17, 2015. BOE/ BOS are currently in the design development phase.
