Abstract: This paper investigates the technical efficiency of Japanese water supply and sewerage services using data envelopment analysis (DEA). We then apply regression analysis to explore the interactions between the efficiencies of water supply and sewerage services on both their own prices and those of the other service. All other things being equal, the results indicate a positive relationship between the efficiency of water supply services and the prices for sewerage services, but no relationship between the efficiencies of sewerage services and the prices of water supply services.
