Kosuzume Purifiction Plant Kosuzume Recreation Plant
Kosuzume Purifiction Plant uses the Sagami River, which runs through the center of Kanagawa Prefecture. Construction was completed in 1965 as co-operated facility in Yokohama City (water supply and industrial water supply) and Yokosuka City, and after two expansion work, the current water treatment capacity is 820,000 m3 per day (about 2.5 cups of Yokohama Stadium). The purified water is supplied mainly to the southern areas of Konan Ward, Asahi Ward, Isogo Ward, Kanazawa Ward, Kohoku Ward, Totsuka Ward, Sakae Ward and Izumi Ward in Yokohama, and also to Yokosuka. It is responsible for about one-third of Yokohama City as a whole and about one-half of Yokosuka City as a whole.

Kosuzume Purifiction Plant Floor Plan
1 Central Management Office
It is the heart of the water purification plant and operates and monitors all facilities 24 hours a day.
2 Pumping Pump
Pump raw water arriving at a point 40 meters below the ground to the ground. Three of the six units are power-saving, reducing power consumption.
3 Sinking Pond
Remove suspended matter in raw water.
Photovoltaic panels prevent the growth of algae and at the same time make effective use of electricity.
4 filtration pond
It removes fine suspended matter through layer of sand. Photovoltaic power generation is performed using a cover to prevent foreign material contamination.
5 Reservoir (No. 2)
We store tap water and send water to the city as needed. The upper part is used by citizens as a sports park.
6 Reservoir (No. 6)
It is a cylindrical ground reservoir. In addition to water supply to the city, it is also used for washing water for filtration ponds.
7 Water Quality Meter
In order to always send safe water, we constantly monitor the water quality of each water treatment process.
8 Drainage Pond
After purifying wastewater is concentrated here, it is sent to the Nambu Sludge Treatment Plant of the Sewerage River Bureau for treatment.
9 Hybrid Outer Lights
We have installed three external lights that turn on only electricity generated by solar and wind power. This is one of the measures to reduce environmental impact.
10 Electric cart
If you are worried about walking around a large area, we will guide you with an electric cart that does not disturb the environment.
