Argo Drain Sub-Basin Facility Project

The project includes construction of underground diversion facilities to capture storm water from LAWA Airside Operations Area and LA County storm drains, conveying and pumping the water through two tunnels using the jack and bore method.  Water is collected from the Argo flood channel located inside LAX and from various LA County storm conveyance facilities.

The stormwater is captured and conveyed in tunnels to a deep underground pump station that lifts the water up to an 8-million-gallon underground tank with an open bottom to allow for infiltration and recharge of groundwater aquifer. PMCS is overseeing the project and providing change management oversight, schedule oversight, review of payment requests, review of RFIs / Submittals, and assistance on resolving technical issues.
