Alvarado Water Treatment Plant New Ozone Disinfection Process
Change to Ozone Disinfection – June 2010
An important part of the Alvarado Water Treatment Plant Upgrade and Expansion Project is to change the water disinfection method from chlorine to ozone. This change will meet new water quality requirements for the plant.
Ozone disinfection is a highly effective way to eliminate any germs and viruses in water. This method has been used at drinking water plants for more than 100 years. Often, customers report improved taste and odor in water disinfected by ozone, as compared to chlorine.
Chlorine will still be used at the plant. Before the ozonated water leaves the treatment plant on its way to storage tanks and pipelines throughout the city, chlorine will be added to provide a disinfectant "residual." This keeps the water disinfected in the delivery system before it is used by customers.
