Application for general sewerage self-financing construction

When constructing at your own expense on the assumption that it will be handed over to the city as a general sewerage facility in the waterway floor, it is necessary to submit a “general sewerage self-financing construction application” to each ward Public Works Office and obtain approval from the general sewerage manager (The Mayor of Yokohama). The details of the construction may be reviewed at the River Management Division and Public Works Office, and conditions for construction may be granted. For details, please contact the Public Works Office of each ward. In addition, please submit construction start notice and construction completion notice to each ward Public Works Office.
Please refer to the Sewer River Bureau Sewer Management Division page for approval and application forms and various forms such as registration form.
