Project: Greater Los Angeles: Goldsworthy Desalter Expansion

Description: Goldsworthy Desalter Expansion project is located in the City of Torrance in Los Angeles Co. The project will expand capacity of an existing desalting facility and construct two new saline plume groundwater extraction wells to provide additional water supply for desalination. The construction project will double the treatment facility’s current capacity to produce 5 mgd of potable water from local brackish groundwater, and over time will remediate a saline plume contaminating the Silverado Aquifer. The existing treatment facility was designed with space to accommodate a second reverse osmosis train to allow for this treatment capacity increase. The project work includes upgrading the existing facility with new RO equipment and infrastructure, expanding the treatment capacity of the facility, drilling and developing new wells, and constructing pipelines.

Reference Number: 3860-PM-1297

Implemented By: City of Torrance, Los Angeles County Flood Control District

Objective: Project will help alleviate drought impacts and assist local public agencies to meet long-term water supply needs, protection of water quality, and augment/restore environmental conditions. The project objective is to create a new local water source in Southern California and improve local water supply reliability. It will reduce reliance on imported water which currently makes up 93% of source water for Torrance Municipal Water. The project will desalinate local groundwater at twice the current rate and, over time, will help remediate a saline plume that contaminated the Silverado Aquifer underlying Torrance.
