Highlights from August 2023
President's Message:
Maximizing Stormwater Capture to Increase
Local Drinking Water Supplies
In a month that historically gets 0.1 inches of rain, August brought a surprising 2.56 inches to Orange County. Due to decades of sound planning, regional partnerships, and investments in infrastructure, OCWD maximized stormwater capture efforts, ensuring not a drop of water was lost to the ocean. The District has also increased water storage behind Prado Dam to more than 3.4 billion gallons of water.

The arrival of Tropical Storm Hilary bolstered our drinking water supply as the rain received was captured in our managed aquifer recharge system, which will eventually percolate into the Orange County Groundwater Basin – a vital resource managed by OCWD that serves 2.5 million people.

Through a historic cooperative agreement with the United States Army Corps of Engineers, a large volume of water can be stored behind Prado Dam and released at rates that the District can capture, further expanding use of local water resources. The amount of storage currently held behind the dam is enough to serve 100,000 people for one year and is valued at an estimated $12.6 million, equivalent to the cost of imported water. This reinforces the need to invest in reliable, local water sources.

OCWD is well positioned to maximize water supply for the region, during wet or dry times. Our long history of active water management and investments have ensured a sustainable groundwater basin that will serve generations to come.
National Water Quality Month
We couldn't let National Water Quality Month go by without highlighting the amazing work of OCWD staff who provide safe, clean water to its communities. OCWD is committed to providing exceptional water quality to the 19 cities and retail water districts it serves in north and central Orange County. Given its commitment to manage and protect the Orange County Groundwater Basin, OCWD implements rigorous water quality sampling, monitoring and testing programs to ensure that when water is delivered to you, it meets all state and federal drinking water standards.

Our state-of-the-art lab, the Philip L. Anthony Water Quality Laboratory, tests for more than 500 compounds, many more than what's required by state and federal laws and regulations. It tests water from approximately 1,500 locations throughout the basin, analyzes more than 20,000 samples each year and reports more than 400,000 results. Our expert staff also monitor constituents of emerging concern, which helps us identify potential water quality issues and allows us to act quickly and proactively to address them.

Next time you’re ready to quench your thirst, look no further than your tap, and take a moment to appreciate the breadth of monitoring and testing that’s done on every drop so you can enjoy a refreshing, high-quality taste of H2O! 💧

Recent Happenings
OCWD in the News
The Groundwater Replenishment System (GWRS) was featured in the Spectrum News 1 story "California seeks to introduce purified wastewater to drinking supplies". Join Executive Director of Operations Mehul Patel, as he takes viewers on a tour of the world's largest water recycling facility.

Recharge Planning Manager Adam Hutchinson spoke with the San Francisco Chronicle and Director of Recharge and Wetland Operations Ben Smith interviewed with KCAL 9/CBS 2 about OCWD’s stormwater capture efforts. The District has more than 3.4 billions of water stored behind Prado Dam. This water eventually gets released at rates that the District can capture and recharge into the Orange County Groundwater Basin.
OCWD Staff in the Community
Lisa Haney, OCWD's Executive Director of Planning and Natural Resources, was invited to speak at the California Miss Earth Pageant. She presented OCWD’s mission of creating a sustainable groundwater supply for drinking water while protecting the environment and how these young women can use specific outreach efforts to enhance the impact of their platforms. The purpose of the pageant is to empower young women to speak on environmental issues that inspire them by developing an environmental platform, promoting civic leadership, and competing for educational scholarships.
GWRS Wins Statewide Award for Expanding Water Reuse
The GWRS final expansion project won the 2023 Capital Project Award at the annual California Association of Sanitation Agencies (CASA) conference. A joint project of OCWD and OC San, the GWRS was recognized for recycling 100% of OC San’s reclaimable wastewater flows, which produces up to 130 million gallons of water a day. That's enough to serve nearly one million people in north and central Orange County.

“The completion of the GWRS reflects a decades-long effort to invest in a more resilient water supply,” said OCWD Board President Cathy Green. “We appreciate the ongoing partnership we have with OC San and look forward to continued collaboration in the future.”
North & South Basin Quarterly Update Published
OCWD is committed to working with the community to solve threats to groundwater. We've published our July 2023 Quarterly Groundwater Cleanup Update, featuring activities in and around the North Basin (affecting portions of Fullerton, Anaheim, Placentia, and Buena Park) and South Basin (affecting portions of Santa Ana, Tustin and Irvine).
Missed our AI in Water Webinar?
There is a lot of buzz around artificial intelligence (AI) and machine learning (ML) these days, with a broad range of tools available to use. These applications can help water utilities improve predicative analytics, insights, and data management and ultimately optimize day-to-day operations and long-term planning.

OCWD is proactively engaged in this subject matter and currently researching and piloting areas where AI can support District operations.
We recently hosted a webinar all about AI and its potential risks and challenges, and emerging technology and opportunities that can be implemented in the water sector. Thank you to our wonderful speakers, Megan Plumlee, Ph.D., P.E., Research Director, OCWD; Kate Newhart, Ph.D., Assistant Professor of Environmental Engineering, United States Military Academy West Point; and Kyle Thompson, Ph.D., P.E., Reuse Lead Technologist & National PFAS Lead, Carollo Engineers who shared great insights and input into this exciting topic.

If you missed it or would like to watch again, please take a look at the recording. 👀💻

(Spoiler alert: AI is here to support enhanced water operations, not take over our jobs)

Sustainably Managing the OC Groundwater Basin
OCWD is one of the few groundwater management agencies able to track the groundwater basin’s “water budget” on a monthly basis. This information allows the District to make more informed management decisions about future water supplies and pumping. View the infographic below to see the groundwater basin’s storage, recharge, and pumping levels, through the end of July 2023.
