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 ensure a reliable wastewater system that protects our waterways and serves our growing population.


Welcome to Our New Website

The Sanitation Districts of Los Angeles County are excited to launch the Clearwater Project website, your online resource for construction information and other important events.

Construction will begin late 2018 in Carson and is expected to end at Royal Palms Beach in San Pedro in 2025. In keeping with the Districts' tradition, we will continue to be good neighbors for the communities in the South Bay.
