Mesa Water has made significant investments to ensure that primary, standby, and backup systems are in place to provide a reliable, safe water supply for our customers and local fire authorities. Mesa Water has the following resources in place to support Costa Mesa Fire & Rescue in its work to protect life and property in our community: Nearly 3,500 fire hydrants that are tested and maintained annually; Backup natural gas-fueled generators to support the water production system, if electricity was cut off or failed for other reasons; Two new groundwater wells, which increased our pumping capacity by 8,000 gallons per minute; and Two of our reservoirs, that hold a total of 28 million gallons of water, are fully operational while being upgraded to increase usable capacity by 11 million gallons during peak demand. Ā In addition to our infrastructure, we operate an emergency notification system called Mesa Water Notify. In the event of a water emergency, we will send customers a notification via email and text. All customers are automatically opted in when they establish an account, as long as we have a current email address or mobile phone number in our customer information system. To confirm we have your correct email address and mobile phone number, please call Customer Service at 949.631.1200. Additionally, Mesa Water routinely coordinates with the City of Costa Mesa and Costa Mesa Fire & Rescue to ensure we are working together on emergency preparedness and response.
