The North City Pure Water Project is the first phase of the City of San Diego's Pure Water Program. The project is designed to augment Miramar Reservoir, which is a source of domestic drinking water supply, with purified water produced at the future North City Pure Water Facility. This Title 22 Engineering Report describes the City’s plan for compliance with the California Code of Regulations (CCR) Title 22 Water Recycling Criteria, including Surface Water Augmentation regulations (CCR, 2017, in progress). This report is prepared in fulfillment with the State Water Resources Control Board, Division of Drinking Water requirements. The draft report and notice of public hearings are available at the links below.

• Recycled Water Study Final Report (July 2012) (PDF)

In January 2004, the San Diego City Council authorized a comprehensive evaluation of all viable options to maximize the usage of recycled water. The study also included analysis and research on the health effects of reuse options and a public participation process. The Reuse Study's stakeholders identified Reservoir Augmentation at the City's San Vicente Reservoir to be their preferred strategy. In October 2007, the San Diego City Council also recognized the North City-3 strategy, also known as San Vicente Indirect Potable Reuse, as their preferred alternative.

Study Mission: To pursue opportunities to increase local water supply and reliability, and optimize local water assets, through a comprehensive study of recycled water.

Study Objective: To conduct an impartial, balanced, comprehensive and science-based study of all recycled water opportunities so the City of San Diego can meet current and future water supply needs.
