How is dirty water treated? What will happen if it is discharged into the river?
If we discharge dirty used water into the river, it will make the river and the sea dirty. So, dirty water is purified in purification tanks and other facilities before being discharged into the river.
Higashihiroshima City also has facilities to purify dirty water. At the Higashihiroshima Water Purification Center in Saijo Cho Taguchi, water used in houses, schools, and factories is gathered through the sewage system and purified before being discharged into the river.
