Yokohama City Sewerage Business Medium-Term Management Plan 2022

The "Yokohama City Sewerage Business Medium-Term Management Plan 2022" is an implementation plan that advocates the direction of measures, business management, and financial management for four years, and specific initiatives for sustainable sewerage management.
The sewerage business of Motoichi is managed with independence as a public enterprise based on the "principle of independent accounting system" and the "principle of rainwater public expenses and sewage private expenses". In order to balance the promotion of measures and financial soundness, we have formulated a medium-term sewerage business management plan, and since the previous plan "Yokohama City Sewerage Business Medium-Term Management Plan 2018" was completed in 2021 (Reiwa 3), We have formulated the following "Yokohama City Sewerage Business Medium-Term Management Plan 2022".
This plan is consistent with the “Yokohama Medium-Term Plan” and is positioned as a “management strategy” that the Ministry of Internal Affairs and Communications requires public enterprises to formulate.
