About Sakae Public Works Office Sewer

From the Yokohama City Sewerage and Rivers Bureau website

We live with clean water. Using water means dirtying the water. It is our duty to clean the dirty water and return it naturally. The sewer protects beautiful rivers and seas.

The drawbacks of the pumping toilet - It is opened from bad smells and the hassle of pumping. Clean and odorless flush toilet can be used in any household.

Many modern cities, including Yokohama, are developing in lowlands. As a result, drainage cannot be performed smoothly, such as during heavy rains, and often suffers from flooding. Sewers play a role in preventing rainwater from accumulating, just like rivers and waterways.

The Dob River causes odors, flies and flies. By improving the sewer system, such Dob River and dirty puddles will be eliminated. It is not only beautiful but also useful for creating a hygienic city.

The method of sending sewage and rainwater to a water reclamation center in separate pipelines is called a "separate sewer". It has the advantage that rainwater can flow directly into rivers and the sea even if heavy rain falls.
Currently, about 70% of Yokohama City's sewerage systems account for 70%.

⇒The sewer in Sakae Ward is almost a separate sewer.

The method of transporting sewage and rainwater used at home to a water reclamation center in one pipeline is called "merged sewer". It is efficient because there is only one pipeline, but there is a problem such as when heavy rain falls, some water must be drained from the pumping station to the river or the sea without sufficient treatment.

In Yokohama City, we are working to improve the water quality of rivers and the sea by developing rainwater reservoirs.
