In August of 2009, the City of San Diego formally commenced exploring options for water reuse and initiated the Recycled Water Study. The city formed a cooperative agreement with San Diego Coastkeeper and the San Diego Chapter of Surfrider Foundation. The study sought to “identify opportunities within the City’s system to maximize recycling and reclamation of wastewater for potable and non-potable uses.” The city recently published the Final Draft Report.
Interest in water reuse is driven in tandem by both water supply as well as wastewater treatment costs and environmental effetcs. San Diego imports 80 percent of its water, making the city vulnerable to price increases and supply interruptions. The city operates Point Loma Wastewater Treatment plant under a modified NPDES permit, which extends until 2015.
