Confirmation of drainage equipment plan

Drainage equipment is a facility for drainage that you maintain and manage.
If you look at the ground around the building (easy to find in a newly built house for sale), there are lids made of concrete or vinyl chloride (it may be a square iron lattice lid for rainwater only). Is called "masu" of drainage equipment. It is basically connected by a pipe between the masu, and at the end it is connected (such as a round made of vinyl chloride, etc.) to the public sewer.

It is your duty to provide drainage facilities, and before the maintenance of the drainage system requires The Mayor of Yokohama to confirm that the plan complies with laws and regulations concerning the installation and structure of drainage facilities.
What you create to obtain confirmation is the "Drainage Equipment (wash toilet remodeling) plan confirmation application".
In the case of detached houses, the application will be submitted to the Public Works Office of each ward.
The application form includes "original" and "duplicate", and after confirmation, the "duplicate" stamped with the confirmed seal will be returned to the applicant.
Construction of drainage facilities can only be performed by a designated construction shop for drainage facilities. (The designated construction shop posts a “Drainage Designated Construction Shop Certificate” in an easy-to-see place of the sales office.)

From then on, the explanation of the drainage equipment plan confirmation application ("exclusion").
Please read the "Yokohama City Drainage Equipment Manual" carefully and contact Public Works Office or Environmental Planning Bureau Sewer Management Division if you have any questions.　The page display in the text is the number of pages of "Yokohama City Drainage Equipment Handbook (Revised in 2006) (partially revised in July 2014)".
