Santa Rosa wastewater treatment plant on Llano Road undergoing energy upgrade

Cleaning wastewater requires huge amounts of energy.
It has to be moved with pumps, blasted with pressurized air and zapped with ultraviolet lights. Even after it’s cleaned, it has to be pumped to local farms and soccer fields or piped 40 miles to be injected into the Geysers steam fields.
All that makes the Llano Road wastewater treatment plant, operated by the City of Santa Rosa, one of the largest energy users in Sonoma County, absorbing between 3 and 7 megawatts of electricity daily.
