Located in the agricultural fields of the Central San Joaquin Valley of Northern California, the cities of Woodland and Davis—and the University of California, Davis (UC Davis)—previously depended entirely upon groundwater wells as the source of their potable water supply. This became a challenge, as the reliability and quality of the diminishing groundwater supply had declined and many of the groundwater wells were old. Faced with these problems and increasingly stringent wastewater discharge regulations, it became important for these communities to diversify their water supply.
