Project: Southern California Edison Catalina (Avalon) Desalination Plant 2

Description: The project consists of design, construction, and operation of the Desalination Plant 2 (Plant 2), which is located adjacent to the existing location of Catalina’s Desalination Treatment Plant 1 (Plant 1). Plant 2 is a standalone and permanent treatment plant -- built in 2016 as a response to recent emergency drought condition faced by Catalina Island. Desalination Plant 2 includes pre-treatment, reverse osmosis (RO) treatment, and post-treatment systems in order to produce potable water per drinking water standards. The new plant has a typical operating capacity of 0.23 MGD and also provides treatment redundancy and system reliability to accommodate future expansion and maintenance.

Reference Number: 3860-P01-342

Implemented By: Southern California Edison

Objective: The objective of this project is to achieve a drought resilient system and mitigate the rate impact to mitigate the impact on the DAC and improve water supply reliability, improve water quality, provide public health benefits, strengthen drought resiliency, and reduce adverse environmental impacts by lessening fresh groundwater withdrawals. The project estimates to add 66 AF of desalination production per year and increase the desalination capacity to achieve 61% of the average customer demand.
