Pure Water San Diego: Engineering the Water Cycle

San Diego is undertaking an ambitious integrated infrastructure programme in the city’s history. Titled Pure Water San Diego, the programme aims to transform the water system into the complete water recycle in order to increase local water supply by 2035.

Pure Water San Diego will eventually deliver 83 million gallons of water per day (MGD) and will be completed in two phases. Phase one will see an additional 30 MGD added by 2025, and Phase two adding an additional 53 MGD by 2035.

The programme will reuse and recycle treated wastewater from the Point Loma Wastewater Treatment Plant. California’s State Water Resources Control Board has also approved direct potable reuse regulations to accelerate the development of systems to develop treatment systems.
