McCarthy Building Companies has started work on a project for North Texas Municipal Water District, constructing new ozone facilities for the existing water treatment plant in Wylie, Texas. The $112-million project will include the installation of ozone generation equipment and construction of two buildings to house this equipment. McCarthy will also install liquid oxygen storage and feed equipment, which will supply oxygen for ozone generation.
The ozone water treatment process reduces disinfection byproducts as well as taste and odor compounds. As part of the project, McCarthy will construct 11 ozone contactors and install side stream injection systems, ozone-quenching and filter backwash chemical feed systems.
The current water treatment facility has a capacity to treat 770-million gallons of water per day and serves more than 1.6 million residents in North Texas. The engineer on the project is Black and Veatch of Dallas. The project is scheduled for completion in January 2014.
