Recycled water is a vital, drought-proof source of water that has been safely treated for reuse after going down the drain. While it is not used for drinking, it is an abundant, affordable and reliable part of the Irvine Ranch Water District’s (IRWD) diverse water supply portfolio. It is used for watering shared community spaces, cooling office buildings, flushing toilets, mixing concrete, industrial uses and fighting regional wildfires.

Recycled water helps us prepare responsibly for the future as demand for drinking water is growing, droughts are more common and recurring, and wildfires are becoming bigger and more frequent. That’s why it is important that we increase our recycled water supply and ability to store it for times of high demand.

The Syphon Reservoir Improvement Project is an investment to expand the existing recycled water storage reservoir. The project will help to reduce our dependence on costly imported water, making us more self-sufficient by allowing us to swap out an expensive source of water for one that is less expensive and more reliable, ensuring we use the right water for the right purpose.

Syphon Reservoir Improvement Project: Investing in Our Future

The Syphon Reservoir Improvement Project is an investment to increase the capacity of an existing recycled water reservoir from 578 to 5,000 acre-feet or 188.3 million to 1.6 billion gallons. By doing so, we can store more recycled water to meet seasonal and future needs. By making more recycled water available, we will reduce our dependence on costly imported water and make our community more self-sufficient.

Safety

IRWD will go above-and-beyond required safety standards. The project will modernize and upgrade the reservoir so that it continues to meet and exceed the latest federal and state safety standards.

The project will be peer reviewed through a rigorous process overseen by a technical advisory panel made up of respected reservoir experts. No rivers or streams feed into this reservoir, which allows IRWD to directly control the flow of recycled water in and out of the reservoir.

Environmental Review Process and Timeline

The project will be subject to a rigorous state environmental review process, including extensive opportunities for public input and stakeholder engagement. The environmental review process is expected to be completed by summer 2020. Construction is expected to take 2–3 years.

Project Benefits

The Syphon Reservoir Improvement Project will help IRWD meet the community’s need for increased recycled water storage. By increasing our ability to store more recycled water, the project:

Meeting Community Water Needs

Why Lose It When We Can Use It?

Drinking water is limited, especially here in Southern California. So how does Irvine Ranch Water District keep our communities so green and beautiful without depleting the drinking water we depend on in our homes and businesses?
The answer is recycled water—an abundant, affordable and drought-proof source of water ideal for many uses. Just not for drinking.

Every gallon of recycled water we use for these purposes saves a gallon of drinking water. And that adds up to 28 million gallons daily.

How The Recycled Water System Works

We have one of the most robust and technologically advanced recycled water systems in the nation .

The Water Balancing Act

Managing our water supply is a balancing act. Recycled water is produced and used every day, but the community’s need for it grows during the dry months of summer. In the wet winter months, when demand is low, our recycled water reservoirs fill up, and excess recycled water goes to waste. Without more room to store recycled water for times of high demand, we will have to use expensive imported water to meet our future needs.

How Important Is Recycled Water?

Recycled water is a crucial reliable source in our diverse water supply and a forward-thinking solution for the future of our community. It’s all about using the right water for the right purpose.

Safety: Always Our Top Priority 

Public safety is our top priority – nothing is more important to us. IRWD is an experienced reservoir operator with a strong track record in reservoir construction, maintenance, performance, safety and facilities construction. IRWD operates five reservoirs, including Syphon Reservoir. The reservoirs are inspected by the state and meet all requirements for safe use. Currently, we monitor all five dams daily and conduct monthly inspections. 

As part of the Syphon Reservoir Improvement Project, IRWD will go above-and-beyond required safety standards. The project will modernize and upgrade the reservoir so that it continues to meet and exceed the latest federal and state safety standards. The proposed project will be peer reviewed through a rigorous process overseen by a technical advisory panel made up of respected reservoir experts.
