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, will be constructed to protect local waterways by addressing aging infrastructure.
Rachel, our tunnel boring machine (TBM), was lowered in sections about 100 feet below ground using the access shaft in Carson.
After being assembled and tested underground, she will start tunneling.
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.
Highlights of the April 15th launch event of the Clearwater tunneling machine are shown in this 2-minute video. To see the entire event and the virtual tour that followed, click here.
A new 5-minute video that provides an overview of the Clearwater Project including what the project is, why it is needed, and how it will be constructed.
