I want to remodel the toilet

When the public sewer is maintained and designated as a treatment area, those who have a building in the treatment area will be abolished as a flush toilet and the human waste septic tank will be abolished within three years from the designated date. Is required to be discharged directly.
To discharge water from toilets and kitchens directly, it is necessary to install drainage facilities and apply for confirmation of drainage equipment plan. Construction cannot be performed unless it is a designated construction shop in Yokohama City. In addition, there is a subsidy and loan system for construction work.

If drainage pipes (drainage facilities) in residential lands are not installed based on laws and regulations, it will not only hinder the maintenance and management of public sewerage, but will also damage the drainage facilities of houses. Please ask the designated construction shop in Yokohama City.

※Designated construction shops are introduced by Yokohama City Pipe Works Cooperative.
