Conservation of Water Resources

Basic Approach to Water Resources

The Nabtesco Group does not require a large amount of water nor water of a certain quality for its business operations. However, since we regard the control of water resources as an important challenge in environmental conservation, we conduct water usage control and water quality control, as well as preventive measures and risk analysis relating to the outflow of hazardous substances.

The amount of water used and discharged at each base are measured every month, and the Group data are accumulated through the environmental information management tool. As for bases where the amount of water per month fluctuates greatly, we conduct surveys to identify contributing factors for the increased water usage, and implement measures to reduce the water use as necessary. As for water quality control, we continuously monitor through monthly voluntary tests and regular inspections by external experts.

In addition, in FY2012 we began controlling global water usage, including that of overseas group companies* Although water usage at our overseas group companies is only 10% of the usage of the Nabtesco Group as a whole, we will continue to implement controls in order to address global water risks.

The Nabtesco Group has collaborated with external initiatives to reduce water usage, responding to CDP Water since FY2014. In FY2018, these initiatives and disclosures were recognized internationally, and the company was named on the CDP A List 2018 for water security.

  • * CDP Water is a CDP program that asks companies about risk awareness and response strategies regarding water risk.

Water Use and Water Discharge Management in Japan

The Nabtesco Group uses groundwater mainly to cool test stands and melt snow in snowy regions (Yamagata and Gifu). We discharge the used groundwater to rivers under the strict water quality control criteria set by the Group. In FY2018, there were no cases wherein used groundwater did not meet the water quality control criteria.

The total volume of water used by the Nabtesco Group in FY2018 amounted to 700,000m3, slightly lower than that used in the previous fiscal year.

Due to heavy rain falls caused by recent climate change, the risk of rainwater flooding our plants is increasing. The Nabtesco Group uses oil-based type and water-soluble type cutting fluids in its business operations and recognizes the risk of hazardous substances contained in these cutting fluids discharged to rivers if rainwater floods the manufacturing facilities. To prevent this, we have been making capital expenditure to install oil-water separation tanks and oil recovery equipment.

In FY2018, we spent around 2.86 million yen to enhance the rainwater discharging function, install drainage pipes, and make our facilities more water-resistant.

Addressing water risks

In FY2014, water-related risks in the areas where the Nabtesco Group’s seven plants (Yamagata, Gifu, Tarui, Tsu, Kobe, Seishin, and Konan Plants) are located were evaluated using the Aqueduct tool provided by the World Resources Institute and referencing the “water vision” announced by the local municipalities. We later increased the number of subject plants and evaluate them every year. The evaluation results confirmed that our Group has low water-related risks. We also began a similar evaluation of our overseas plants in FY2016.

The FY2018 survey confirmed that the overseas plants that have high water risks are those in the Beijing and Shanghai areas of ​​China. Because risks related to regulations and reputations in the local area are the major concerns, wecontrol such risks through ESH audits and monitoring of laws and regulations. In China, we also confirmed risks related to water quality. However, we concluded that water-related risks were low on the whole in light of the low impact of water quality on our production.

In addition, to further promote CSR activities through the supply chain, we are conducting surveys on water use (water intake, wastewater, water quality, etc.) of Tier-1 suppliers in Japan and overseas, and evaluation of water risks using AQUEDUCT. Each supplier is analyzed and evaluated, with the results provided in the form of written feedback. We also visit specific suppliers directly and conduct interviews. This serves to enhance communication with suppliers while supporting knowledge sharing regarding environmental management and improved environmental stewardship. As well as engaging with suppliers, we actively participate in environmental and water related regional councils, exchanging information and conducting activities related to water conservation in order to maintain harmony with the local community.
