Catalina Desalination Storage and Distribution Project Wrigley Reservoir, 9MG, 1425 Elevation, Reach 1 Start Station A, 1145 Elevation, Reach 3 Start Station E, 295 Elevation, Reach 5 End
Project Description Desal Storage & Distribution System: New Booster Pump Station Enhanced Bi-Directional Flow Pipeline (roughly 2,000 feet upgraded, 26% of pipeline infrastructure) Extend Desal Distribution to Hamilton Cove (incremental ~5% of Catalina water demand) Enhance Desalination Storage from <1 MG to 9 MG by connection to existing Wrigley Reservoir
Project Outreach Ongoing presentations of major milestones to the community at City Council Meetings (2017-2019), including summaries of the 2017 Catalina Desalination Feasibility Study, 30% project design and grant applications. Letters of Support obtained by: City of Avalon, City Manager Denise Radde Tony Budrovich, President and CEO, Catalina Island Conservancy Jim Luttjohann, President and CEO, Catalina Island Chamber of Commerce Janice Hahn, Supervisor, 4th District, County of Los Angeles Alan Lowenthal, Member of Congress, Congress of the United States, House of Representatives, 47th District, California Ben Allen, California State Senator, 26th Senate District Patrick O Donnell, Assemblymember, 70th District, California Legislature Ricardo Lara, Senator, California State Senator, 33rd District Prior outreach and updates have been made available by the City of Avalon on their website, this would span to include future, long-term project messaging and reporting benefits.
Funding Details Funding: Total Project Cost: $4,170,000 Grant Request: $1,500.000 (36%) Matching Funds: $2,670,000 (64%) Matching Funds Sources: Pending, state funds may be $0 to $1,460,0001 O&M costs per year: Pending Partners: Southern California Edison, City of Avalon 1. The project scope is currently included in a proposal to DWR s Water Desalination Grant Program with an expected decision coming in Q3/2019. Depending on award and amount, the project s matching funds and sources may be impacted. Absent a grant, and provided the permit and/or conditions do not materially change the scope, the project is expected to move forward with alternative funding sources that may include local/third party contributions and/or utility customers. It is the intent to mitigate a utility customer bill impact. Matching funds (including sources) will be more definitively known prior to construction start (Q2/2020).
Program Preferences Project is located ~22 miles from California mainland (~30 miles Avalon to Long Beach), No undersea pipeline; water that is not produced domestically needs to be barged Over 1 Million visitors to the island; approximately 81% from CA, 27% from LA County Historically, island has depended upon fresh water sources (82%) compared to desal (18%); in Avalon fresh water dependency is 77% and desal is 23% Climate trends, rain dependency, and fresh water systems have been problematic in meeting island water demand; 7 of the last 10 years have experienced water use restrictions Southern California Edison and City of Avalon are interested in pursuing water projects to strengthen resource adequacy while mitigating impacts to the community Proposed project contributes to regional water self-reliance; it allows a incremental drought resilient water source by increasing the capacity factor of on island desalination Project innovatively leverages existing infrastructure to unlock additional value Project improves water quality for customers in Avalon Project reduces reliance on instream flows, especially in periods of drought; this results in significant local ecosystem benefits Expected Useful life 30 years CEQA and Permit Completion expected within 12 months of final award
Benefits Increases water supply by increasing the capacity factor of the existing desalination treatment plant via storage improvements and greater distribution connectivity. Nominal % of System Capacity Avg. (10 Year) 9% AF/Year MG/Year Capacity 38.24 12.5 Drought ('13-17) 11% 6% Extends desal distribution connection from 75% of customers to 81%; also a prerequisite to further connectivity with remaining remote systems Adds 9 MG of desal storage without construction of new tank or reservoir (instead: upgrade 2,000 feet of pipe, add booster station) Avalon, is located within Los Angeles County, although is completely isolated from mainland California water systems and infrastructure.
