新河岸川水循環センター, Water treatment facility in Wako, Japan
The Shingashigawa Water Circulation Center is a wastewater treatment facility in Wako that processes water from surrounding municipalities in Saitama Prefecture. The plant uses multiple treatment lines to clean the water before it returns to the Arakawa River.
Wastewater treatment operations at this facility began in April 1981 to address growing environmental needs in the region. Since then, it has served the surrounding municipalities of Saitama Prefecture.
The facility contributes to public health education through organized tours, allowing visitors to understand water treatment processes and environmental protection.
Visitors can join a guided tour of the facility that lasts about 60 to 90 minutes and requires advance registration. The nearby Asaka Station connects conveniently through a community shuttle service.
One of the five treatment lines is specially equipped for removing nitrogen and phosphorus from the water. This advanced processing allows for higher water quality when returning it to the river.
