Phase 1 - North City

Phase 1 MapPhase 1 of the Pure Water Program includes several projects that will clean recycled water to produce 30 million gallons per day of high-quality purified water, reducing the City’s dependence on imported water. The purified water will blend with the City’s imported and local water sources and be treated again at the Miramar Water Treatment Plant and distributed to the public. The projects include the Morena Pump Station and Pipelines, the North City Water Reclamation Plant Expansion, the North City Pure Water Facility and the North City Pure Water Pump Station and Pipeline.

To view the pipeline routes and facilities, please visit our Phase 1 interactive map.

Phase 1 Distribution Area

The purified water will blend with imported and local water sources before it is treated again at the existing Miramar Water Treatment Plant and distributed to the public. The purified water distribution area will include the portion of the City of San Diego that receives potable water from the Miramar Water Treatment Plant in addition to the City of Del Mar.

Miramar Reservoir Tracer Study

The City of San Diego Public Utilities Department conducted a tracer study at Miramar Reservoir in mid-July 2019 as part of the Pure Water Program. The results of the tracer study will be used to confirm the accuracy of a hydrodynamic model of Miramar Reservoir. The model will show how water moves through the reservoir. Below is more information on the tracer study:

Phase 1 Working Groups

On April 10, 2018, the San Diego City Council voted unanimously to move forward with Phase 1 of the Pure Water Program by certifying the Pure Water San Diego North City Project Final Environmental Impact Report/Environmental Impact Statement (EIR/EIS) and approving two construction management contracts for the Phase 1 projects. As part of the approval, the City Council directed the Public Utilities Department to create project area Working Groups whose members would provide informed input and feedback regarding opportunities to avoid, minimize or mitigate potential construction impacts and assist the City with implementing the conditions that are part of the approved site development permit. Four Working Groups are currently being convened, one for each of the major construction segments: 1) Bay Park/Morena, 2) Clairemont, 3) University City and 4) Scripps Ranch/Miramar. Below are the meeting schedules and handouts provided at each meeting.
