SAN DIEGO — A California brewing company made beer using recycled sewage water from the Pure Water San Diego program.
The beer, called the Full Circle Pale Ale, was created by the Stone Brewing company. San Diego May Kevin Faulconer was among the first to drink the newly brewed beer and called it “delicious,” KGTV reported.
The Pure Water San Diego program recycles the wastewater leaving homes and business The wastewater are treated in steps including ozonation, where ozone gas destroys disease-causing microorganisms; biological activated carbon filtration, where the water is filtered through coal and crushed sand; membrane filtration, in which micro-porous separating layers filters the finest particles before the water goes through reverse osmosis and UV/Advanced Oxidation.
Currently, about 85% of San Diego’s water supply came from the Colorado River and Northern California Bay Delta. The rest comes from local runoff and rainwater. The Pure Water project aims to turn enough wastewater into drinking water to supply one third of the city’s needs by 2035.
