Source of Water in Fukuoka, Japan
Fukuoka’s tap water comes mainly from rivers and reservoirs in the Fukuoka region, including the Chikugo River, Kyushu’s largest river. The city also receives water from a network of dams and other water-resource facilities.
The water is treated at Fukuoka City’s purification plants, where it is filtered and disinfected before entering the distribution system. It then travels through underground pipes to homes and businesses throughout Fukuoka.
