Evoqua Water Technologies announced that it was chosen to provide water treatment solutions and services to Paso Robles, Calif.
As the historic drought in California continues, the city of Paso Robles faces significant water supply challenges. In the past, the city relied entirely on groundwater, drawn from a large aquifer. To diversify and improve the integrity of its water supply, the city launched the Lake Nacimiento water project and secured a supplemental 4,000 acre-ft per year water entitlement. The use of the Lake Nacimiento water will enable the city to reduce its dependency on the Paso Robles Groundwater Basin and provide a reliable long-term water supply. Evoqua Water Technologies was retained to design, manufacture and install a granular activated carbon adsorption system as a part of the new treatment plant.
The new treatment plant is utilizing Evoqua’s UltraCarb 1240AW granular activated carbon media to treat the Lake Nacimiento water supply for removal of total organic compounds. By utilizing this carbon, the city of Paso Robles expects to treat more water per lb of carbon than would otherwise be possible using standard coal-based carbons. This will reduce the life cycle cost of treatment and save the city of Paso Robles and its water users money over time.
