About the Treatment Plants
LA Sanitation operates four treatment and water reclamation plants that serve over four million people within two service areas containing over 600 square miles.
The main purpose of these treatment facilities is to remove potential pollutants from Los Angeles’ sewage in order to protect our river and marine environments and the public’s health.
The organic and inorganic particles that are removed make up less than 0.1% of the incoming sewage, yet the plants remove over one million pounds of debris, grit, and organic solids every day.
