Response to Biodiversity

Contributing to Biodiversity Through Business Activities

METAWATER's wastewater systems are used to treat and regenerate water that has been polluted by humans and return (discharge) it to the river.
Insufficient treatment, or the discharge of untreated wastewater at this time, can contaminate rivers and even the sea into which the river water flows, affecting the fish and waterfowl that live there. METAWATER conducts its business activities with the awareness that its technologies are compatible with biodiversity.
In the Tama River in Tokyo, water pollution increased due to an increase in domestic and industrial wastewater flowing into the river during a period of rapid economic growth. The river was foaming, and the oil ball floating in Tokyo Bay became a social issue. However, now that wastewater systems have proliferated, and wastewater technology has become more advanced, the water quality of the Tama River has improved, and sweetfish have returned.
