To prevent water pollution, we thoroughly manage not only the water used in our plants but also rainwater drainage.
Reductions in the amount of water used and purification of drainage water
- Water used
- We aggressively reuse water within our operations, and try to reduce the total volume of water used. Wastewater undergoes high-level processing in our wastewater treatment facilities before being released into rivers or elsewhere.
- Rainwater drainage
- In preparation for unexpected occurrences such as the discharge of oil in rainwater, we have installed sensors to detect irregularities and a system to stop effluent from leaving our sites.
At the Oppama Plant, for example, a system was introduced to strengthen our water pollution prevention efforts. Water quality sensors were attached to the discharge ports of the wastewater treatment facility, and discharge of water outside the grounds is automatically suspended if water quality problems are detected.
