Studies of water-supply businesses have traditionally focused on the economies of scale achieved through mergers between small- to medium-sized water utilities. For this reason, there have been almost no studies on the management of metropolitan water utilities that are already large enough to achieve economies of scale on their own. The majority of Japanese metropolitan water utilities are based in downstream river basins and are thus subject to influences from upstream, including wastewater flows from residences. This renders improvement of raw water quality difficult. Thus, the supply of quality tap water requires further enhancement of water-purification technologies. At the same time, in metropolitan areas, where water-supply systems were introduced earlier than in other parts of the country, the primary water infrastructure (e.g., water treatment plants and pipelines) is becoming increasingly old and decrepit. Renovating this infrastructure is also an urgent task. Given the declining revenues resulting from shrinking populations and water-saving efforts on the part of users, it is becoming more and more difficult for metropolitan water utilities to continue to achieve sustainable development and growth by sticking to their traditional management practices, which they developed and implemented on their own. Metropolitan water utilities are now required to enhance cooperation with stakeholders located along the same rivers, thereby building up new business models that enable them to overcome management problems which they cannot solve by themselves.
