I'd like to replace it because the lid of my house has broken. Where should I ask?

Use the following procedure to replace “lids” such as sewage masu and rainwater masu, which are drainage facilities in residential lands.

1.I'll check the current situation. (Creating photos and sketches will help you when purchasing.)

• Manufacturer, part number
• Materials (made of concrete, resin or PVC, iron, etc.)
• Shape (circular, square, etc.)
• Dimensions (diameter, vertical, horizontal, thickness, etc.)
• Mounting status of lid and masu

2.Purchase and install lids at home centers and building materials stores.

3.If you are unable to purchase it at a home center or if you do not know how to exchange it, please consult with the Yokohama City Drainage Equipment Designated Construction Shop designated by The Mayor of Yokohama.

• If the lid cannot be replaced because there is no stock due to discontinuation of production, etc., construction may be performed to replace it with a new masu or drainage pipe.
  When requesting replacement of lids or construction from a Yokohama City Drainage Equipment Designated Construction Shop, consult with us in advance about the contents and costs before contracting.

(Reception hours 8:30-17:00) However, the union will only introduce it.
