The Clearwater Project was approved after a multi-year evaluation of the main sewer system serving nearly half of Los Angeles County. A new 7-mile tunnel, a key component of the project, is being constructed to protect local waterways by addressing aging infrastructure.
Take an up-close look at how Rachel, our tunnel boring machine (TBM), works. In this short video, we explain how the parts of the TBM work.
This 5-minute video provides an overview of the Clearwater Project including what the project is, why it is needed, and how it is constructed.
