Pasadena Firm Awarded Water-Treatment Contract: Ralph M. Parsons Co. will perform final design assistance on the Metropolitan Water District’s Oxidation Retrofit Program. The $200-million project will retrofit two of MWD’s water-treatment facilities with a preozonation process, which uses ozone instead of chlorine to disinfect drinking water. This process is said to result in cleaner drinking water with significantly fewer disinfection byproducts. About 750 million gallons of water per day will be treated with ozone at the Joseph Jensen Filtration Plant in Los Angeles County.
