Our concerted approach to cooperation between government and private sector
As a business partner with comprehensive capabilities
Domestically, measures must be taken immediately to address the elements of financial difficulties and engineer insufficiencies seen by local governments operating water supply and sewerage projects, the aging of facilities and equipment that were improved during Japan’s period of rapid economic growth, major earthquakes and torrential rain, and so on against the backdrop of a decreasing population.
Since the PFI Act went into effect in 1999, there has been an increase seen in terms of public-private partnership projects involving the utilization of private funds, technologies and know-how for public infrastructure improvements. In addition, since the revision of the Water Supply Act in 2018, the outsourcing of project operations to private sectors (including concessions) has been drawing attention. While expectations of private companies are rising, we are steadily expanding project areas and accumulating know-how.
Track record for public-private partnership participation in the areas of domestic water supply and sewerage
In addition to projects involving the PFI method and DBO method and which entail the comprehensive entrustment of processes spanning from design and construction to operational and maintenance management, we are also recently engaged in projects which include project plan establishment support, asset management, and fee collection. We have participated in various public-private partnership projects.
Realization of management suitable for specific facilities by leveraging lots of know-how
Track record for major public-private partnership projects entrusted to the METAWATER Group
Track record for PFI/DBO projects entrusted to the METAWATER Group
At each site, much experience and know-how are accumulated through daily operations and technological capabilities are enhanced by sharing that experience and know-how.
