Providing an abundance of local, reliable, clean, safe water. THE BOARD OF DIRECTORS
Mesa Water® is governed by a five-member Board of Directors.

THE PURPOSE OF MESA WATER DISTRICT (Mesa Water®)

THE SERVICE AREA
Mesa Water® provides water service to 110,000 customers in an 18-square-mile area. The service area includes the City of Costa Mesa, parts of Newport Beach, and some unincorporated sections of Orange County, including the John Wayne Airport. The service area is divided into five divisions. One individual from each division is publicly elected to serve a four-year term as a Director. THE SOURCE
The District provides water that is a blend of local ground water. Groundwater, or well water, is pumped from Orange County's natural underground reservoir, or groundwater basin, via Mesa Water's eight wells. Mesa Water® supplements its groundwater with water from the Mesa Water Reliability Facility (MWRF). The MWRF is designed to process amber-colored groundwater from a deep aquifer and was re-opened in January 2013. The facility was completed under budget. The MWRF helps Mesa Water® provide 100 percent of the water it serves from local water supplies, achieving a long-time goal of its Board of Directors. THE MISSION
Mesa Water District, a local independent special district, manages its finances and water infrastructure, and advocates water policy, while reliably providing an abundance of clean, safe water to benefit the public’s quality of life.

You count on water being there when you need it. Keeping it reliable takes ongoing work.
Reliable water service depends on a connected system working together. Wells bring groundwater to the surface, treatment facilities prepare it for drinking, reservoirs store it, and pipelines carry it to homes and businesses. 💧

Mesa Water maintains 317 miles of pipeline along with the facilities that support your daily water supply. Routine inspections and proactive maintenance help identify problems early, while planned improvements keep equipment and infrastructure ready for continued service.

It’s the ongoing work behind the water you count on every day.

Reliable water service takes financial planning, too.

Two independent financial agencies, Fitch and Standard & Poor’s, have given Mesa Water their highest possible rating: AAA. Think of it as a top-grade report card for how well we manage our finances. It also means we can borrow at lower costs when we repair and upgrade the pipes, wells, and facilities that bring water to your tap.
