Soil and dead leaves are deposited in the gutter around the parking lot. When cleaning, can I just drain it to the rainwater pipe?　Also, if it is useless, do I have to treat it as industrial waste?

If the gutter is a personal property, its management will be performed by the owner.

Soil and dead leaves that were cleaned during cleaning may cause clogging, so please do not flush them into rainwater pipes.

In addition, earth and sand and dead leaves during cleaning become general waste.
The disposal method of general waste differs between household and business, so please contact the Resources and Waste Recycling Bureau office for details.

If the gutter is a facility in Yokohama City, the city will clean it, so please contact Public Works Office in each ward.
