Veolia Japan with the Joint Venture “Mizu Partner JOYO” has been selected as the preferred negotiating party for the “comprehensive outsourcing contract for Joyo City’s drinking water and waste water services” and has signed a contract of 3,800,000,000 yen (excluding tax) for the next 10 years with Joyo City, located in Kyoto prefecture, on September 30, 2025.
This Joint Venture, which was named "Mizu partner JOYO", is composed of five companies: Veolia Jenets Co., Ltd.; Fuji Surface Information Co., Ltd.; Japan Maintenance Engineering Co., Ltd.; West Japan Railway Company; and Asia Air Survey Co., Ltd. They are joining forces to provide drinking water and sanitation services to more than 73,000 residents.
This project adopts a new contractual scheme promoted by the Japanese government called "Water PPP Level 3.5" (which includes private company support for equipment renewal planning in the scope of work).
This new contractual scheme was created to address a range of challenges faced by the Japanese water infrastructure sector, such as declining revenues from water tariffs due to population decrease, increased facility renewal costs from the aging infrastructure, and difficulties securing skilled engineers.
The new contract in Joyo City entrusts the Mizu Partner JOYO joint venture with the comprehensive management of drinking water and wastewater services, covering everything from water volume management and facility maintenance to customer service (billing, meter reading, technical support, and revenue collection). It also includes essential functions such as crisis management, after-hours support, and the preparation of renewal plans for water and wastewater infrastructure, as well as cross-cutting tasks like public communication, training, and process improvement for the city. The goal is to ensure comprehensive, stable, and sustainable operations of Joyo City’s water services, tailored to the structural challenges facing Japan’s water sector.
All companies in the Mizu Partner JOYO Joint Venture will collaborate closely with Joyo City by holding discussions and facilitating handovers to prepare for the project's scheduled launch in April 2026.
