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.
Take a close-up look at how Rachel, our tunnel boring machine (TBM), was lowered to its starting depth and assembled.
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.
