San Diego County's New Sewage Recycling Systems: A Response to Drought and Water Independence

1/26/2026, 11:07:42 AM

Overview of the Sewage Recycling Initiatives

In response to prolonged drought conditions and rising water costs, San Diego County is set to launch three sewage recycling systems: Pure Water Oceanside, East County Advanced Water Purification, and Pure Water San Diego. These projects, which began planning over a decade ago, aim to transform sewage into potable water, addressing both immediate water supply concerns and long-term sustainability issues. The systems are expected to produce a combined total of approximately 47.5 million gallons of purified water per day by the end of 2027.

Motivations Behind the Projects

Local leaders cite multiple motivations for these initiatives. El Cajon Councilmember Steve Goble emphasized the desire for water independence, stating, “We wanted to be more in control of our water supply and our water rates.” Oceanside Mayor Esther Sanchez highlighted the need to keep water rates affordable for the city's low-income residents, noting that purified sewage costs less than imported water. A recent analysis indicated that Pure Water San Diego will produce water at $2,100 per acre-foot, compared to $2,600 from the San Diego County Water Authority.

Financial Implications and Challenges

The financial burden of these projects is significant, with Pure Water San Diego costing $1.3 billion, East County Advanced Water Purification at $950 million, and Pure Water Oceanside at approximately $160 million. However, the San Diego County Water Authority faces challenges as it may need to raise rates due to reduced sales from member agencies implementing sewage recycling. The authority is contractually obligated to purchase more water than needed, complicating its financial structure.

Environmental Considerations

Environmental groups support these recycling efforts, arguing that they will reduce sewage discharge into the ocean, which can harm marine ecosystems. Former San Diego Mayor Kevin Faulconer noted that the city was also motivated by potential legal action from environmental groups regarding the under-treatment of sewage at the outdated Point Loma Wastewater Treatment Plant. Upgrading this facility would have cost an estimated $3 billion, making the recycling systems a more viable option.

Implementation Timeline and Storage Solutions

The timeline for these projects varies, with Pure Water Oceanside expected to complete a major expansion by the end of 2023, producing 6 million gallons per day. The East County project is scheduled to begin operations in fall 2026, generating 11.5 million gallons daily, while Pure Water San Diego is set to start in early 2027, ramping up to 30 million gallons per day. A notable challenge for the East County project is the need for above-ground storage, as it will be the first instance in California where purified sewage is stored above ground, specifically in Lake Jennings.

Criticism and Public Perception

Despite the progress, there are concerns regarding public perception of sewage recycling, often referred to as "toilet to tap." Faulconer actively countered this narrative by promoting the safety and necessity of the projects, having personally endorsed the concept after visiting a similar facility in Orange County.

Conclusion

The launch of these sewage recycling systems represents a significant step for San Diego County in addressing water scarcity and ensuring a sustainable water supply. As the projects near completion, they will not only provide a new source of drinking water but also reshape the region's approach to water management amidst ongoing environmental challenges.
