Preserving Water Resources
The Anritsu Group believes that water is a precious resource that supports life and society, and that its circulation and maintenance of water quality are essential for creating a sustainable future. In order to continue our business activities in harmony with nature, we will work to conserve water resources, with a focus on the following activities.
- Prevention of water pollution and compliance with laws and regulations
To preserve water quality, we will strive to minimize pollution risks from wastewater and other sources by establishing voluntary management standards that exceed legal requirements, in addition to complying with all laws and regulations. - Reduction of hazardous chemicals
We will achieve a safer water environment by reducing the use of hazardous chemicals as much as possible with the aim of discontinuing their use. - Management and reduction of water withdrawal
To protect the local water cycle and the health of ecosystems, we will continue to manage and reduce water withdrawal at our business sites and will not use more water than necessary. - Conservation of freshwater ecosystems
By thoroughly implementing the above initiatives, we will strive to maintain the balance of ecosystems in rivers and inland freshwater environments, thereby coexisting in harmony with nature.
Target・Progress
| Target | Result for 2024 |
|---|---|
| Reduce the total amount of water withdrawal by the Domestic Anritsu Group, Anritsu Company (U.S.), and Anritsu EMEA Limited (U.K.) by 2.2% or more compared to FY2019 by FY2026
(A reduction of at least 5.0% by FY2030) |
24.3% reduction |
Activities and Achievements
Effective use of water
The Anritsu Group conducts the following activities to make effective use of water.
■ Reducing Water Withdrawal
Water is mostly used for toilets and washing hands in the domestic group. We have reduced water consumption through efforts such as leakage inspections and upgrading to water-saving toilets. Circulated water is used at production facilities.
At the Hiratsuka Site, the rinsing water used by the facility to degrease metallic materials is reused by circulating it through filters and ion-exchange resins, which reduces annual water consumption by approximately 40 m3. In FY2020, Anritsu Company (U.S.A.) started its thin-film device manufacturing business, requiring large amounts of water for cleaning, and will work to reduce water consumption by circulating the cleaning water.
These efforts resulted in water consumption of 61,233 m3 in FY2024, a 24.3% reduction from the base year of FY2019.
Water-saving toilets
■ Consideration for Water Resources
At the Atsugi Site, groundwater is used for flushing in some toilets. We are replacing the toilets with water-saving ones to reduce the amount of water pumped from underground aquifers to prevent groundwater depletion. With the exception of toilet flushing water, all water used is city water (tap water) supplied by a third party. At the Global Headquarters Building, we have installed a rainwater permeation basin to prevent road flooding and river flooding.

■ Identifying Water Risks at Development and Manufacturing Sites
The Anritsu Group is working to assess the risks and make effective use of water resources at the Atsugi Site, the Tohoku Site, Anritsu Company (U.S.A.), and Anritsu EMEA Limited (U.K.), all of which have high water consumption.
According to Aqueduct, Luton, UK, where Anritsu EMEA Ltd. is located, has high water stress*, and both Koriyama in Fukushima Prefecture, where the Tohoku Site is located, and California, where Anritsu Company is located, are expected to have high water stress by 2030. In order to make effective use of water resources, GLP2026 has set a target to reduce the total amount of water used by the Domestic Group, Anritsu Company, and Anritsu EMEA Limited.
* Water stress: A state in which the amount of water usable per person per year is less than 1,700 tons and in which people feel that their daily living is inconvenienced. A very high level of water stress means that the shortage of water in a region is so severe that more than 80% of its population has no sufficient access to water for agricultural, household, or industrial use.
Water consumption
The Anritsu Group consumes water through evaporation in cooling towers for air conditioning, boilers for humidification in clean rooms, and watering of plants. Consumption in FY2024* was about 15% of the total water withdrawal for the entire group.
* Consumption: Total amount of water withdrawn that is not discharged into sewers or rivers. In the case of Anritsu Group, there is no water incorporated into products. Evaporated and transpired water, and water used for irrigation of plants, etc. is considered equivalent.
Water intake source
At the Atsugi Site, groundwater is used for flushing in some toilets. All other water is purchased from third parties such as local governments, which use surface water as their water source.
