Norman water treatment plant improvements enter Phase II: The city council, acting as the Norman Utilities Authority, will consider approving a $1.5 million contract with Carollo Engineers for Phase II improvements at the water treatment plant located in northeast Norman. The improvements follow studies conducted in 2006 and 2007. Carollo performed a chlorine pilot study, an ozone pilot study and a detailed electrical evaluation, according to city staff reports.
The first phase rehabilitated the electrical infrastructure “to allow the future installation of an ozone unit to be used as a primary disinfectant and to control taste and odor,” according to staff reports. Capacity was increased from 14 to 17 million gallons per day, and other equipment was upgraded, including the installation of a new solids contact clarifier, replacement of the filter media and replacement of lime feed and carbon dioxide systems.
Phase II will include an eight-month ozone pilot test, a Hydrologic Engineering Center River Analysis System study of the creek located on site and design services. This water treatment plant project addresses the city’s drinking water needs at the plant located in north east Norman.
