I want to remodel the toilet

When the public sewer is maintained and designated as a treatment area, those who have buildings in the treatment area will use the flush toilet and the human waste septic tank to the public sewer within three years from the designated date. It is mandatory to release it directly.
In order to discharge water from toilets and kitchens directly, it is necessary to install drainage equipment and apply for “drainage equipment plan confirmation”. Construction can only be performed by a designated construction shop in Yokohama City. There is also a subsidy and loan system for construction, so please use it.

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 sewers, but also damage the drainage facilities of houses. Please ask the designated construction shop in Yokohama City for construction.

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