Rules for Using the Sewage System in a Comfortable Way
Inquiries: Public Relations Service Section, General Affairs Division, Bureau of Sewerage, Tokyo Metropolitan Government
●Do not pour gasoline or kerosene down the drain
Pouring volatile, combustible items down the drain may cause serious accidents, such as an explosion.
●There are various items that should not be poured down the drain
If you flush disposable diapers and paper that does not dissolve in water down the toilet, this could cause clogged pipes.
In addition, do not dispose of chopsticks and plastic sheets down the kitchen or bathroom sink.
●Let hot water cool down before pouring down the drain
Pouring hot water down the drain as is, may damage the pipes.
●Do not pour oil down the drain
If you pour used cooking oil, such as leftover oil from stir-fried or deep-fried items, down the sink in your kitchen, it could clog the sewage pipes and cause odors as well. Take care of leftover oil by using it up completely, wiping the pan before washing, or absorbing the oil in cloth or paper.
●Be careful of torrential storms during the rainy season and typhoon season
When rainfall is heavy, rainwater from surface streets can easily flow into semi-basements and basements, creating a danger of flooding.
Since opening the door may become difficult due to the pressure of water flowing in, it is wise not to go into semi-basements and such areas.
