Important Public Notice About Your Drinking Water


Catalina Island

Safely providing electricity, water, and gas to Catalina Island is our top priority. Below is helpful information about these services for Catalina Island's 4,100 residents, its commercial and industrial customers, and its one million annual visitors.

For more information on the recent 60-year utility anniversary, view the Energized story.

Catalina Island Water Services

Since 1962, we’ve been providing water service to Catalina Island through water storage, wells, water treatment and distribution, and, more recently, desalination. For information on desalination's 30-year Catalina anniversary, view the Energized story.

On Oct. 30, 2020, SCE filed a General Rate Case application with the California Public Utilities Commission to increase water rates. For more information, view the Notice of Application and Energized story.

Effective February 2, 2023, Stage 1 Mandatory Water Conservation is no longer in effect

The January 2023 series of rain events have resulted in a significant increase in the Middle Ranch Reservoir (MRR) level, from 456.41 acre-feet on January 9, 2023 to 737.5 acre-feet on January 30, 2023. With residual recharge expected in the coming months and operation of the desalination plant(s) to supply drinking water to customers in Avalon, water supplies are sufficient to meet the normal demands of the system and deactivate Stage 1 mandatory water conservation on Catalina Island. Stage 1 had been in effect since July 2022, after the Reservoir dropped below the 600-acre-foot level. If you would like to monitor the Middle Ranch Reservoir’s water level status, please visit the City of Avalon website for the latest update.  

On February 2, 2023, SCE submitted a Tier 1 Advice Letter 135-W with the California Public Utilities Commission (CPUC) to deactivate Stage 1 of SCE’s Schedule 14.1 Staged Mandatory Water Conservation and Rationing Plan (Water Rationing Plan) for the Catalina Island water system.

SCE provided community updates of Stage 1 deactivation in February 2023, including a newspaper ad (Catalina Islander) and Avalon City Council presentation. Customers are encouraged to maintain voluntary water conservation to support a sustainable water supply on Catalina Island.

We will continue to make water conservation devices available to customers. You can pick up low-flow shower heads, kitchen and bath faucet aerators and automatic shut-off hose nozzles at our Pebbly Beach office located at 1 Pebbly Beach, Avalon, CA 90704 or City Hall.

We strongly encourage you to conduct a personal household water audit. An audit will help you assess how and where you use water, how much you use, and find opportunities to save. Refer to for more information on how a household water audit can help you save both water and money.

We guarantee that we’re providing you with a safe and dependable supply of drinking water by regularly monitoring the water supply. We’re required to test for a number of different contaminants in the water system, with the timing of the sampling varying based on the state’s requirements, from daily to annually. The company conducts more than 2,300 tests for over 150 drinking water contaminants.

In order to ensure that water is safe to drink, the U.S. Environmental Protection Agency and State Water Resources Control Board, Division of Drinking Water, established regulations that limit the amount of certain contaminants in water provided by public water systems. Monitoring results are routinely submitted to the Division of Drinking Water and are subject to review and inspection by the agency.

For more information about what we test for and how it compares to California water quality standards, please refer to our annual Consumer Confidence Report | en ESPAÑOL

Catalina Island Gas Services

We also provide commercial and residential customers on Catalina Island with gas services. Below are answers to some questions you may have related to your gas service.

Catalina Gas Services: Frequently Asked Questions

If you smell propane gas or suspect a leak has occurred, follow these important rules:

  • Do not touch, breathe, or make contact with leaking propane gas
  • Get everyone out of your home or building, and open doors and windows to ventilate the area
  • If outside, leave the area immediately by walking into the wind and away from the propane gas
  • Do not light a match, start an engine, use a cell phone, or do anything that may create a spark as the leaked propane gas can ignite
  • Turn off machinery and equipment, but never approach equipment that is surrounded by a gas cloud
  • Provide a description of the propane leak and its location
  • Warn others to keep away

Propane gas is supplied to our customers via a pipeline system- the safest, most reliable and most efficient way of distributing propane gas. Pipeline failures on Catalina Island are rare because our pipeline system is designed, installed, tested, operated, and maintained according to strict standards used by us, the pipeline industry and those required by local, state, and federal government agencies.

We continuously monitor the pipeline system through a combination of safety programs:

  • Patrols of the pipeline system
  • Visual ground inspections and leak surveys
  • Computerized system reports and records of line pressure 24 hours a day
  • Construction practices that help prevent rusting and minimize corrosion

Everyone can contribute to the safety and security of the pipeline system on Catalina Island. Any activity near or on a pipeline route—even something as simple as planting a tree or building a fence—can potentially damage a pipeline.

A gouge, scrape, dent or crease to a pipeline or its coating may cause a break or a leak in the future. If you plan to dig, drill, or engage in any other activity that could damage a pipeline, call Dig Alert at 1-800-227-2600 at least 48 hours before you dig or excavate.

When you call Dig Alert, our personnel will come out and mark the pipeline route for you. When excavating near propane gas piping, the excavation must be done with hand tools until the propane gas line is found.

If you know of even minor damage to a pipeline, please contact us immediately at 800-367-8851 so we can investigate.

Usually, an underground “main” pipeline located in the middle of the street in front of your home or business supplies propane gas. Additional underground piping runs from the main pipeline to the propane gas meter that supplies propane gas to your home or business. In open areas, main pipelines are marked with aboveground signs to indicate the general location, our contact information, and that the pipeline contains propane gas. Markers do not provide information on the depth or number of pipelines in the vicinity and the markers do not indicate the exact position of the pipeline.

Pipeline routes must be kept free from structures and other obstructions. If a pipeline crosses your property, please do not plant trees or high shrubs along the route. Also, do not store or place anything on or near the pipeline route without first contacting us so we can explain the company’s construction guidelines to you. Call us during normal business hours at 800-367-8851 if you have any questions.
