Napa, CA will install advanced ozone treatment in the new water treatment plant in Jamieson Canyon. The plant is undergoing a $35 million upgrade and expansion to handle more water from the State Water Project for city of Napa customers. There is still money in the project’s $3.5 million contingency account to pay for additional ozone injection equipment. More ozone treatment will cost $1 million to $1.5 million. The new equipment will enable the plant to meet future water treatment requirements, while improving the taste of the water, she said.
Ozone is widely used for taste and odor control in drinking water.
