President’s Message—Strengthening O.C.’s Water Reliability
The Orange County Water District (OCWD) operates a complex system of more than 25 recharge facilities so it can continue to provide a reliable water supply for the 2.4 million people it serves.
On October 27, OCWD and the Orange County Flood Control District (OCFCD) dedicated Fletcher Basin to increase recharge to the Orange County Groundwater Basin while strengthening flood control for the region.
Fletcher Basin, the 4.8 acre project site located near Fletcher Avenue and Batavia Street in the city of Orange, was formerly used to retard stormwater flow prior to discharge into the Santa Ana River. OCWD manages the Orange County Groundwater Basin and uses a series of basins in Anaheim and Orange, including the new Fletcher Basin, to replenish groundwater supplies. It is extremely cost beneficial to construct and maintain a means of capturing rainwater while gaining more control of our local water reliability. Read More…
GWRS Final Expansion Agreement Passes
The collaboration between OCWD and the Orange County Sanitation District (OCSD) dates back to the mid 1970s when OCSD provided treated wastewater to OCWD for its Water Factory 21, the first plant in the world to use reverse osmosis to purify wastewater to drinking water standards.
The two agencies then went on to jointly build the Groundwater Replenishment System (GWRS) in 2008. The world’s largest advanced purification facility was expanded in 2015 to produce 100 million gallons of water per day.
Building on nearly 50 years of collaboration, OCWD and OCSD staff recently completed a Joint Exercise of Powers Agreement for the final expansion of the GWRS. Both boards of directors unanimously voted to enter into the agreement, which outlines each agency’s responsibilities for each of the projects that make up the GWRS Final Expansion Project.

California Groundwater Basin Boundaries Change
The California Department of Water Resources (DWR) released final 2016 modifications to California’s groundwater basin boundaries, completing a critical step in the implementation of the state’s Sustainable Groundwater Management Act (SGMA). DWR presented the final basin boundaries to the California Water Commission, which approved them. Included in the approved boundary modifications were changes proposed by the Orange County Water District to DWR’s Basin 8-1, the Coastal Plain of Orange County Groundwater Basin. Read More…
Draft Alternative to Groundwater Sustainability Plan Ready for Public Review
Formal groundwater management in California can be traced back to 1934 when the Department of Water Resources (DWR) mapped and numbered the state’s groundwater basins. In Orange County, the basin was named Basin 8-1, the Coastal Plain of Orange County Groundwater Basin. Since that time, jurisdiction over groundwater basins remained a local concern and management programs evolved to varying degrees. Recent drought conditions and, in some places the over-drafting of groundwater basins, demonstrated the need to enhance management of these important water supplies. Read More…
OCWD Experts Present at Korea International Water Week
OCWD Advanced Water Quality Assurance Laboratory Director Lee Yoo and Recharge Planning Manager Adam Hutchinson were invited to participate in Korea International Water Week (KIWW).
Yoo provided a presentation titled “Water Supply and Quality Management in Orange County, California” at a World Water Cities Forum—a part of KIWW.
The importance of the Forum was to discuss and to share leading practices and identify factors that will enable the implementation of innovative and practical solutions for sustainable water supply. Yoo also presented to environmental engineering students at Keimyung University, Daegu, Korea. Read More…
Midge/Mosquito Eradication Program Underway
OCWD has more than two dozen recharge basins in the cities of Orange and Anaheim. The water in the basins is “moving”—in some cases, up to five feet a day or more percolates into the groundwater basin. Except for twice a year when the basins are drained and cleaned to maximize stormwater capture, water is replenished and does remain in the basins. The basins can become breeding locales for pesky midges and mosquitos.
The District implements an effective and safe method of eliminating them. Read More…
Marcom Award Recognizes OCWD Presentation
The Orange County Water District received the Gold Award in the Video/Audio category by MarCom Awards. OCWD was recognized for its 40 minute animated PowerPoint presentation titled “Water Manufacturing Process,” which is used at the start of each Groundwater Replenishment System (GWRS) tour.
“The District’s Public Affairs team took a serious subject, added creativity and made it extremely interesting. It’s become a great way to educate our guests prior to their GWRS tour,” said OCWD President Cathy Green.
The PowerPoint presentation includes dimensional animations the District co-created with Linda Macpherson of New Water ReSources and Peter Swanson of Global Visions and Associates. They demonstrate the groundwater basin geology and the California water network, among others.
MarCom Awards judges reviewed more than 6,000 entries from throughout the world for its 2016 creative competition for marketing and communication professionals. Winners were selected from over 300 categories in print, web, video and strategic communications.
Lab Hosts IC User Group
OCWD’s Advanced Water Quality Assurance Laboratory hosted an Ion Chromatography (IC) User Group meeting with Thermo Fisher. OCWD tests water samples with three different IC systems to detect chloride, sulfate, and bromide that would indicate potential seawater intrusion, nitrate, fluoride, inorganic disinfection byproducts, as well as toxic emerging contaminants like hexavalent chromium and perchlorate. The instruments are used every day, and are vital to many inorganic analyses.
The attendees came from both commercial and public entities throughout Southern California, and included a number of District laboratory staff. Discussion topics covered included IC theory, ion chromatography tandem mass spectrometric (IC-MS/MS) for low level detection of perchlorate and haloacetic acids (HAAs) without a time consuming derivatization process, new analytical technology, and a demonstration of the Chromeleon software eWorkflow for easier methods development. The seminar was well received by all in attendance and facilitated a technical information exchange between District laboratory staff and external colleagues.
OCWD-UCR Collaborate on GWRS Research
The Groundwater Replenishment System (GWRS), the world’s largest water purification system for indirect potable reuse utilizes a three-step method: microfiltration, reverse osmosis, and ultraviolet light with hydrogen peroxide for advanced oxidation. A University of California, Riverside (UCR) researcher has recently been awarded $300,000 from the National Science Foundation (NSF) to compare the addition of chloramines to the UV/peroxide advanced oxidation process (AOP) and will partner with OCWD to do so.
For the NSF project, UCR Assistant Professor of Chemical and Environmental Engineering Haizhou Liu will team with OCWD Principal Scientist Ken Ishida (pictured) to investigate UV/chloramine AOP and the impact chloramine compounds have on the UV/peroxide AOP commonly utilized for water purification.
