Induction of private sector partnership into a municipal wastewater treatment facility of the local government of Daegu City, South Korea was studied. Performance of the plant operated by a private party following the management contract for the period of three years (1998-2000) was examined Quality control parameters determined throughout pre and post-privatization periods were analyzed. Efficiency of the plant in term of operational cost based on per capita removal of bio-solid material was evaluated. Under the private management, influence flow rate was increased by 5% in the year 2000 compared to pre-privatization period, BOD and COD in the incoming flow were reduced to 30.4% and 20.5% respectively.  While those in outgoing flow were reduced to 26% and 14.6%, respectively. Approximately 40.7% of TSS was reduced at influent level, presumably due to improvement in drainage system. Work force was reduced to 29% which proportionally increased the per capita removal of bio-solid materials by 41%. In spite of the fact that the consumer price index was increase by 18.8% treatment cost per ton was reduced to 11.5%. Increases in the hydraulic loading rate over and above optimizing expenditures of the plant. Successful running of the partnership during the trial period recommended the city government of Dargu, South Korea that ownership of the facility could be handed over to the private operator probably under a concession type contract for a period of 25-30 years.
