Sewage Plant, Japanese Style
Atami City needed a new sewage treatment plant. But, as in all of Japan, land is scarce. And as a sightseeing spot and hot spring resort, Atami City wanted neither to mar its natural beauty nor to pollute its air. So, the city decided to build an underground sewage treatment plant topped with a hotel and amusement complex. The plant occupies 2.5 acres and has a 9.5 million gallons per day maximum treatment capacity. Plant efluent is discharged through an outfall line into the ocean and does not harm the bathing area. The exhaust, deodorized with ozone, 108 is discharged from atop the cliff. Bulletin, Welsbach Corp.
