San Diego's Water Future: Rising Costs and Local Initiatives

San Diego County Water Authority officials anticipate that wholesale water rates could increase by as much as 150% over the next decade. This projection is largely due to the agency's difficulty in selling its water supply, exacerbated by the implementation of the billion-dollar Pure Water project, which aims to recycle sewage into potable water. According to a draft of the authority's long-term financial plan, volumetric water rates could rise from approximately $2,000 per acre-foot next year to between $3,500 and $5,000 per acre-foot by 2035. San Diego City Councilmember Stephen Whitburn emphasized the need for strategies to mitigate the impact of these rate hikes on residents and businesses.

The Pure Water San Diego Program is expected to provide nearly half of the city’s drinking water by 2035, significantly reducing the need for wholesale water purchases. This shift is projected to lead to a 25% to 40% decline in water sales for the Water Authority, further straining its financial model. Lindsay Leahy, a representative on the water authority's board, warned that without successful out-of-state sales, local communities could face higher costs as the authority compensates for reduced revenues.

Water Authority General Manager Dan Denham noted that a recent settlement with the Metropolitan Water District of Southern California has facilitated potential out-of-state sales, which could help alleviate future rate increases. The financial plan also suggests that factors such as lower interest rates and increased grants could moderate the anticipated rate hikes.

Marco Gonzalez, executive director of the Coastal Environmental Rights Foundation, criticized Jim Madaffer, a city representative on the Water Authority board, for undermining the city's water independence efforts. Gonzalez argued that Madaffer's public statements against the Pure Water initiative contradict his responsibility to advocate for San Diego's interests. He called for a representative who would support local control and sustainability in water policy.

While the Water Authority's financial plan outlines a structured approach to managing rate increases, there are concerns about the long-term viability of its revenue model given the anticipated drop in water sales. Critics argue that the authority's reliance on external sales may not be sufficient to offset the financial impacts of the Pure Water project.

As the Pure Water project progresses, the Water Authority plans to gradually increase wholesale rates throughout the 2030s to manage the financial impact on consumers. The agency is also expected to provide updates on its efforts to secure out-of-state water sales by spring 2026, which could play a crucial role in stabilizing future rates. The ongoing debate over local representation and water policy will likely continue to shape the region's approach to water management in the coming years.
