Water Reclamation Plants

LA Sanitation (LASAN) operates four water reclamation plants that serve over four million people within two service areas covering 600 square miles. These plants effectively remove pollutants from the sewage to produce recycled water, protecting our river and marine environments as well as public health. Together, they have a combined capacity of 580 million gallons of recycled water per day. The water can be used in place of potable water for industrial, landscape and recreational purposes in addition to other beneficial uses.

Biosolids, a byproduct of wastewater treatment, can be used as a fertilizer and soil amendment for agricultural and landscape applications. Another byproduct of the plant operation is energy. Biogas from Hyperion is converted into electricity and used to run the plant.

From the initial process of screening and removing large items to the chemicals we add to clean the water, there is a very specific and organized way in which we must follow the steps used during the treatment process to ensure safety and best results.
