San Diego relies heavily on imported water that is vulnerable to drought, climate change and environmental regulations. With demand expected to rise as the city grows, the San Diego Public Utilities Department (SDPUD) partnered with CDM Smith to strengthen reliability and local resilience.

Dozens of potential water supply options were reviewed to identify strategies that balance cost, reliability and feasibility.
A stakeholder advisory committee representing various community groups shaped objectives and ensured broad public alignment.
A 1-mgd demonstration project was built to support community education and strengthen confidence in future programs.
The resulting long-range plan provides a flexible roadmap that SDPUD will update every 5 to 10 years as conditions evolve. It positions the city to expand conservation, boost local groundwater use and adopt purified wastewater for indirect potable reuse. “Planning for climate uncertainty is an important part of remaining a resilient city,” says deputy director Marsi Steirer, underscoring the city’s commitment to reliable, cost-effective and environmentally responsible water service
