Helping the City of San Diego complete their water cycle
Due to limited local sources, 85 percent of the City of San Diego’s fresh water is imported from the Colorado River and California State Water Project. A lack of control over its own supply makes San Diego more vulnerable to drought, seismic events, and climate change. And, the cost of this water has almost tripled in the last 10 years.
In contrast, 92 percent of the wastewater leaving homes and businesses is treated then discharged into the ocean. Always a forward-looking community, San Diego saw this resource as an opportunity. The Pure Water Program transforms the city’s water system into a complete water cycle. At full implementation in 2035, it will provide one-third (83 million gallons per day) of San Diego’s water supply locally and reduce ocean discharges by approximately 50 percent.
Stantec is leading the team providing program management services for this multi-billion-dollar effort. Our involvement includes creating a program-wide delivery strategy and robust program governance structure with associated procedures, plans (e.g., risk, quality), controls, business processes, and reporting requirements. We developed preliminary designs of all projects (including 30 percent design for the North City Pure Water Facility), and are providing independent review of final designs, construction planning, and operation and maintenance readiness planning. The Stantec Team also provides the city with extensive regulatory support.
Phase 1 of the program will deliver 30 million gallons per day of purified water to the Miramar Reservoir; the purified water will then be blended with imported and local sources before being treated again at the Miramar Drinking Water Plant, then distributed to the public.
