ABSTRACT
Climate change impacts, such as higher average temperatures and prolonged drought conditions, have affected regional and local water supply reliability. The City of Santa Monica has long been a leader in promoting sustainability and is implementing several innovative water supply projects to develop alternative water supplies—including stormwater, dry weather urban runoff, and municipal wastewater—to provide a diverse, sustainable, and drought-resilient local water supply. The City is developing the first MBR (Membrane Bioreactor) system and cartridge filtration system to receive log removal credits for potable reuse in the State of California, the first stormwater treatment project in the State of California that will augment groundwater supplies via direct injection, and the first municipal flow reversal RO (Reverse Osmosis) system in the United States. Collectively, these alternative water supplies sources will reduce the City’s reliance on imported water supplies and meet as much as 99% of its water demands through local water resources.
KEYWORDS
