Mesa Water Celebrates 60 Years of Serving our Community Safe, Affordable, Reliable Water

COSTA MESA, Calif.; August 18, 2020 — Mesa Water District (Mesa Water®) is celebrating its 60th anniversary, a tremendous milestone in the organization’s history. Founded in 1960, the top-performing public water agency provides its community with safe, affordable, reliable water that is 100% sourced from local groundwater supplies – a unique accomplishment in Orange County.

“For the past 60 years, Mesa Water has provided pure, plentiful and affordable water to a region best known for some of Orange County’s top businesses and landmarks, including the OC Fair & Event Center, Segerstrom Center for the Arts, Orange Coast College, and Vanguard University," said Mesa Water Board President Shawn Dewane. “We look forward to the next era of innovation, efficiency and service as we continue to satisfy our community’s water needs.”

From its early roots when the community’s water came from natural underground springs via artesian wells, to the present, when Mesa Water provides clean, safe water to businesses and more than 110,000 residents in today’s bustling service area, the award-winning agency has an eye to the future with key initiatives underway.

As part of its Capital Improvement Program, Mesa Water is investing in its water system and facilities, including:

  • constructing two new wells to increase local water production capacity;
  • ongoing pipeline integrity testing to ensure economical and timely replacement of infrastructure for continued reliable service of high-quality water to customers; and,
  • renovating the Mesa Water Reliability Facility (MWRF), with the addition of a state-of-the-art water education center.

The MWRF ensures that Mesa Water is more than equipped to meet future water needs. Mesa Water supplements its groundwater with water from the MWRF. Source water for the MWRF is pulled from deep below ground, with an amber tint from ancient redwoods. This amber-tinted water is safe to drink and of higher quality than more expensive water imported from Northern California and the Colorado River. Mesa Water uses state-of-the-art nanofiltration technology to remove the amber tint and adds the clear, purified water to its water supply.

Mesa Water has received numerous accolades throughout the decades, including its recently renewed AAA credit rating from S&P Global Ratings and Fitch rating agencies -- the highest achievable by an organization. The coveted ratings reflect Mesa Water’s operational effectiveness and efficiencies, including excellent financial management practices.

Additionally, Mesa Water won the first place 2020 California Municipalities Utilities Association Resource Efficiency & Community Service Award for Mesa Water’s Pipeline Integrity Program (PiP). The PiP successfully addresses the industry-wide issue of renewing and replacing water system pipelines in an economical, effective and timely manner. Mesa Water uses a condition-based approach to determine a pipeline’s useful life by conducting nondestructive and destructive testing. Through PiP testing data, Mesa Water successfully demonstrated the useful life estimate of its pipelines is actually 142 years, saving the district and its ratepayers an estimated $230 million dollars over the next 30 years.

As one of the most efficient water agencies in Orange County, and with its deep commitment to excellent customer service and investment in infrastructure,      Mesa Water is positioned to continue to successfully serve its community for generations to come.
