Overview of the Clearwater Program


The Sanitation Districts of Los Angeles County (the Sanitation Districts) manage a wastewater system that serves over 5 million people. The system provides wastewater conveyance, treatment and reclaimed water management. We are committed to protecting public health, the environment and precious water resources.

The Clearwater Program is the Sanitation Districts’ new facilities planning effort that looks at the future infrastructure and wastewater management needs for the Joint Outfall System through the year 2050. The Master Facilities Plan will ensure the continuation of the wastewater system's high level of service, provide the ability to serve our growing population, evaluate aging infrastructure, and help our facilities to continue meeting state and federal environmental regulations.

The Facilities Plan has identified the need for a new tunnel and ocean outfall to convey effluent from the Districts' largest treatment plant to the ocean.After evaluating 50 potential alignments for a tunnel and locations for shaft sites (to access and work in the tunnel), four feasible alignments have been identified.The Sanitation Districts and the U.S. Army Corps of Engineers are evaluating the potential impacts of each of the four alignments in an environment impact report (EIR) and environmental impact statement (EIS), respectively.

The Clearwater Program will benefit residents and businesses in 73 cities, including portions of the city of Los Angeles, and unincorporated areas of the county - all part of the Sanitation Districts' Joint Outfall System.

Your participation in the Clearwater Program is very important to us.We invite you to register here for bulletins and updates and to contact us with your comments, suggestions or questions.

Update:  Draft EIR/EIS to be released in February 2012 for public review and comments.
