The city of Norman operates sewage treatment works that serve the city and the University of Oklahoma. Major problems include: (1) a treatment facility that is inefficient and cannot meet state and Federal standards for effluent quality; (2) an existing collection system that cannot accommodate existing flows; and (3) inadequate collection and treatment capacity for future growth. Alternatives to accommodate expected flows to the year 2000 were analyzed. Based on environmental analysis and public participation, the following appears to be the most cost-effective alternative: new interceptors, lift stations and collection lines; upgrading of the present treatment plant using bio-discs to provide secondary treatment; and sludge facilities for anaerobic digestion followed by wet-injection disposal. Principal impacts of this alternative would be: facilitation of the conversion of about 600 acres of environmentally significant agricultural lands to urban land uses; support of orderly, environmentally sound growth in compliance with the city's land use plan (COMPLAN); approximately a 3 percent increase in pollutant loadings to Lake Thunderbird; improved water quality in the South Canadian River; reduction of odors and elimination of overflows within the collection system; and lifting of the hookup moratorium in the Bishop Creek area.
