Introduction of water reclamation centers, etc.
Last Updated September 20, 2024
The sewerage facilities in Yokohama City include the Water Reclamation Center, which cleans domestic wastewater, etc., the Sludge Recycling Center, which recycles sludge, and the pumping station, which relays domestic wastewater and drains rainwater to rivers and the sea. There are three main types of facilities.
Over the course of 23 years, 11 facilities were constructed at the Water Reclamation Center, including the Chubu Sewage Treatment Plant in 1962. To make it easier to collect sewage, the city is divided into nine parts according to the terrain and the sewage in the city is cleaned.
In 2005, the sewage treatment plant was renamed the Water Reclamation Center.
The Sludge Recycling Center started operation in 1978 by the Southern Sludge Treatment Center, the first incineration facility in Yokohama City, and the Northern Sludge Treatment Center, which changed the treatment method to sludge intensive treatment in 1987, started operation. In 1989, the Southern Sludge Treatment Center was changed to sludge intensive treatment and has a full-scale system of two centers.
This was also renamed from the sludge treatment center to the sludge recycling center in 2005.
Since the Shimo-Nodani Temporary Pumping Facility started operation as a rainwater pumping station in 1952, 12 relay pumping stations and 14 drainage pumping stations have been operating to the Kusu pumping station, which started operation in 2004. .
In addition, as a countermeasure against flooding of heavy rain in recent years, the construction of an enhanced pumping station is being promoted.
This leaflet introduces the mechanism of water treatment at the Water Reclamation Center.
