Water Intake Management Enhanced by Installing Groundwater Purification Services

Hitachi Astemo, Ltd.
2020

The Hitachi Astemo Atsugi No. 1 Plant manufactures automotive components such as pistons and continuously variable valve lift systems. The plant previously used groundwater in its production process and tap water alone for drinking, handwashing, and in the cafeteria.

In fiscal 2013, the plant introduced groundwater purification services in order to reduce the amount of tap water used. This has made it possible to use groundwater for drinking, handwashing, and in the cafeteria as well. This measure has reduced the amount of tap water used at the Atsugi No. 1 Plant from 68,262 m³ in fiscal 2012 to 6,500 m³ in fiscal 2020 — a reduction of more than 90% (61,762 m³).

Maintaining two systems to supply drinking water has the additional benefit of strengthening the plant’s Business Continuity Plan. During water supply outages, an emergency generator can be used to pump ground water. This gives the plant a system that helps supply water to local residents in times of emergency.
