Graton’s New Eco-Friendly Wastewater Treatment Plant Graton will soon have a new disinfection system for its wastewater treatment plant. We have picked a pasteurization process to do this, the same heating process used to kill dangerous bacteria in milk and other dairy products. It will meet the state and federal water quality standards, and it means we no longer have to use chlorine, a dangerous and toxic greenhouse gas, for the final stage of wastewater treatment.
