Water Usage

Goal

Reduce water consumption at all global production sites by 6% vs. FY2015 result as of FY2020.

Our Stance

As usage of water increases worldwide due to economic development and population increase, there are growing global concerns regarding water risk. OMRON is committed to reducing its water intake in order to effectively use limited water resources.

FY2017 Overview

Since fiscal 2014, OMRON has kept track of water resource data based on CDP’s water program.

In fiscal 2017, water intake at all production sites worldwide was down 5.9% compared with fiscal 2015, as a result of efforts at the sites.

In fiscal 2017, OMRON set environment-related social issues to address, together with the company's identified sustainability issues and long-term goals. Accordingly, all of its production sites worldwide have been working to make more effective use of water resources.

Yasu Office's Initiatives for Water Use Reduction

Yasu Office in Japan requires a large amount of water for the manufacturing of semiconductors, and utilizes groundwater as an intake source.
As groundwater is high in metal, salt, and other impurities, the office uses iron/ manganese removal and ion-exchange devices to filter the water.
As repeatedly used, filters accumulate dirt and require regular backwashing and cleaning.
The office previously discharged all of the treat water used for cleaning to sewerage, but changed its water treatment process in order to reuse rather-clean treat water, except for the water used for early-stage cleaning.
As a result, the office realized to cut groundwater intake by 5,300m3 a year.

Addressing Water-related Risks

OMRON assessed and identified sites with water-related risks by using WRI's Aqueduct, which is a CDP Water Program's evaluation tool, together with a water risk analysis service provided by a risk management consulting company.

High-risk sites are situated in Dalian, China and Bekasi, Indonesia, and the amount used in fiscal 2017 was 165,000m3. These sites have not yet received instructions from administrative authorities to reduce the amount of water taken in or to improve quality of wastewater. However, OMRON Group sites in these areas are implementing voluntary measures to preserve water resources.
