In most of Asian countries, recent urbanization causes, coupled with weak governance, serious impediments for public infrastructure services and serious water pollution problems. The effective countermeasures are requested world-wide. The UN's proposal on Millenium Development Goals is one of them. ODA is a main engine to promote technical transfer with capacity building generally leading to unsuccessful results so far.
Hereupon, the authors intend to propose a new approach based on integral basin management systems (BMS), which have been applied successfully for every water-related problems including heavy water pollution in Japan. It consists of mainstay structural measures (centralized sewage works) and supplementary non-structural measures (on-site sanitation systems). Firstly, an analysis is made on the workability of BMS approach under rapid urbanization process during the high economic growth period in Japan. Then, an analysis is made on BMS application models for two Asian mega-city cases to verify how it could realize appropriate and flexible solutions in those basins.
