Tokushima Prefecture, Kamiishi Town.
The wastewater treatment plant located in the suburbs.
Furukawa Toda is the inspector here, and his daily job is to check and maintain equipment, inspect the site environment and conduct safety checks, as well as record data related to equipment operation, water quality testing, and handling of anomalies.
In the afternoon, while at work, Furukawa held a record form and walked to the edge of the Sedimentation Pool.
This Sedimentation Pool has always been under his responsibility.
The wastewater delivered from the town's pipes undergoes preliminary treatment here. As the water enters the Sedimentation Pool, it is left to stand, allowing gravity to cause suspended solids to settle at the bottom.
Since this is the area for preliminary treatment, the water quality here is undoubtedly the worst.
Murky and mixing with nauseating solid debris, the water color is eerie, and the smell is extremely unpleasant.
Tap, tap.
