I want to install a disposer, what should I do?

We ask that you refrain from installing a single disposer (direct input type disposer).

If the kitchen garbage is crushed and drained into the sewer pipe, it may accumulate on the sewer pipe or increase the load on the water reclamation center, which may reduce the processing function.

Also, in the combined sewer area, crushed materials may flow out into rivers and seas on rainy days.

Based on the above, we ask for self-restraint, but based on the “Disposer Wastewater Treatment System Performance Standards for Sewerage (Draft) (March 2013) created by the Japan Sewerage Association. About thing which we did, we can install.

This system is a system that crushes kitchen garbage, treats wastewater, and then drains it into the sewer system. Many manufacturers have certified products.

In addition, in order to install this system, appropriate maintenance based on the "Yokohama City Disposer Wastewater Treatment System Handling Guidelines" is required with the submission of the "Drainage Equipment Plan Confirmation Application" based on the Yokohama City Sewerage Ordinance.

For more information, please contact Environmental Planning Bureau Sewer Management Division.
