In considering San Diego’s long-range water resources planning, ensuring a reliable water source is essential. Due to limited local water supplies, the City of San Diego is exploring water purification as a potential water supply for San Diego. At the City’s Advanced Water Purification (AWP) Facility, recycled water is purified using microfiltration/ultrafiltration, reverse osmosis, and advanced oxidation with ultraviolet light and hydrogen peroxide. While water purification is a proven technology in some areas, California lacks regulations for certain water purification scenarios. Water purification is part of the City of San Diego’s water resources strategy, as established in the Long-Range Water Resources Plan (2002-2030), that includes planning, conservation, recycled water, water reuse, and watershed resource protection to help meet future water needs.

Guests will learn about San Diego’s water supply source and challenges, the science of water purification, and how it can provide a reliable drinking water supply for the San Diego community. Guests will then take a guided walking tour through the AWP Facility, where they will see the equipment up close and will view the resulting purified water. Guests will also view a video of the Orange County Groundwater Replenishment System’s water purification process that is currently in operation. Following the tour, a panel of experts will answer questions from the audience on technical, regulatory, policy and outreach issues associated with the City’s water purification efforts. This conversation will delve into more detail on the safety of the purified water and constituent removal, how San Diego is leading the way in developing a regulatory pathway and necessary policy for water purification scenarios, how public outreach has played a key role in gaining public acceptance, and potential planning, environmental and economic benefits and impacts of a successful program.  Additional information on Pure Water San Diego is available at: www.purewatersd.org.
