"Rachel" Unveiled: Clearwater Project Begins

Clearwater Project (1)

The Clearwater Tunnel Machine Launch Event on April 15

The L.A. County Sanitation District's (LACSD) Clearwater Project is underway. This important project will protect local waterways by addressing critical aging infrastructure. Treated water from the Joint Water Pollution Control Plant in Carson is discharged out of two tunnels that are 60 and 80 years old. They've been in continuous operation since the 1950's. These tunnels are connected to our waterways, and there are now many concerns about the age and location of these tunnels. The LACSD concluded that buliding a new 18-foot tunnel is the best way to address these concerns. The new tunnel will run from the plant to existing ocean outfalls. The Clearwater Project will address our aging infrastructure, will make our system more reliable, and protect our local waterways. 

On April 15, the Sanitation Districts hosted a virtual event to unveil "Rachel", the tunnel boring machine (TBM) for the Clearwater Project.  At the event, they also recognized the student finalists in its TBM naming and art contests. Rachel will spend the next 3.5 years tunnelling slowly deep underground to create a new tunnel that will be more reliable and functional, and will better protect our precious waterways. This is a once-in a lifetime project that we are pleased to share with you as the tunnel boring machine begins its work. Learn more about the Clearwater Project here.
