Our Approach

Due to the increasing global population, among other factors, total household use of water has increased sixfold since 1960. ^*1 In 2024, 2.1 billion people did not have access to safely managed drinking water, ^*2 and an estimated 5 billion people will face water shortages globally by 2050.^*3

To realize the circular economy outlined in LIXIL’s Environmental Vision 2050, we have designated water sustainability as one of our focus areas. As a leading company in water technology, we are advancing efforts towards global water sustainability today and for generations to come, so everyone can fully enjoy the benefits of bountiful water: actively pursuing the responsible use of water in our business processes, or providing safer and better-tasting water.

To achieve our goals, we are taking a comprehensive strategic approach and pursuing mid-term targets through all three phases: Our Operations, Our Value Chain, and Expanding Our Impact. Going beyond simply fulfilling our corporate responsibility to minimize the environmental burden of our business and products, we aim to create new value in the environmental field together with all stakeholders in order to have an even greater positive impact on the global environment and society.

Our Operations

LIXIL promotes responsible water use in our operations globally, and has set targets to improve water use efficiency (water intake/production output) by 20% at our business sites by FYE2031 (vs. FYE2019). In FYE2025, we increased our water use efficiency across the company by 33.3%. In addition to reducing water usage at sites that use water in manufacturing processes, we are working to identify related business risks in each region at sites that use water for manufacturing to take appropriate steps to recycle and manage wastewater, particularly at sites that suffer from water shortages, in efforts to improve efficiency.

Improving Water Use Efficiency

We are advancing efforts to utilize recycled water in order to manage our water resources effectively. In FYE2025, we used approximately 630,000 m³ of recycled water. We also reduced water consumption at our plants through initiatives such as discontinuing water sprays for cooling roofs by applying thermal insulation coating to rooftops, and upgrading toilets with better water-saving performance. At our plants in the Asian and North American water-stressed regions, we are implementing more progressive initiatives to increase the use of recycled water and reduce water consumption.

Managing Wastewater

LIXIL's plants have established legal standards or stricter voluntary standards in each country to conserve water sources in their catchments and to carry out thorough wastewater management. Wastewater containing chemical substances is strictly controlled and purified through membrane filtration and biological treatment at the wastewater treatment plant to a level well below the standard values. In addition to the daily monitoring performed by each plant, LIXIL conducts third-party inspections to confirm water quality standards.

Initiatives at Sites with Water Risks

Water Risk Assessment Process

To better understand local conditions and introduce appropriate measures to address the problem of increasingly scarce global water resources, LIXIL is conducting annual surveys to identify water risks at all production sites that use water in their manufacturing processes. Our risk assessment process starts with creating a geographical risk profile using the international WWF Water Risk Filter assessment tool. We then conduct surveys of sites that are revealed to be high-risk. This approach enables us to perform comprehensive water risk assessments.

In addition, we have been participating in the Corporate Engagement Program run by the Science Based Targets Network (SBTN) since FYE2023 and have been contributing to the establishment of guidelines related to water risk assessment at SBTN. In FYE2024, we assessed water quality risks in addition to water shortage risks using the LEAP approach, TNFD's assessment methodology. In FYE2025, we conducted a Water Impact Assessment to evaluate the impact of our business activities' water usage on natural capital. Based on the assessment results of each site, we will continue to explore more concrete countermeasures and monitor water-risk sites by conducting interviews to understand the actual state of physical risks, countermeasures, and regulatory risk trends.

At our factory in Thailand, where the risk of water shortages is high, we adopted a water circulation system for recycling rainwater and factory wastewater. We have continually optimized our water consumption at our sites and reduced our annual industrial water usage by approximately 196,700 m³ in FYE2025 (vs. FYE2024).

Responsible Water Use at Sites with Water Risks

We are advancing initiatives to reduce water intake and manage wastewater for responsible water use in our business processes. At LIXIL India Sanitaryware Plant in Andhra Pradesh, India, we have achieved 100% on-site water recycling by implementing a Zero Liquid Discharge (ZLD) system. A ZLD system treats wastewater from the manufacturing process, converting impurities into solid waste and recirculating the treated water into the manufacturing process. This plant also recycles domestic wastewater from toilets and the cafeteria, achieving zero wastewater discharge from the facility. This system not only helps reduce water intake but also contributes to water pollution prevention.

Our Value Chain

LIXIL will continue our efforts to contribute to a global reduction of two billion m³ per year through various products and services such as water-saving faucets and water-saving toilets, extending the target year from FYE2025 to FYE2031. We help end-users reduce water consumption through our products and services, and prevent water leakages with our IoT-enabled smart controllers.

Expanding Our Impact

LIXIL is working to reduce the risk of groundwater contamination by increasing access to safely managed sanitation services and safer water. We strive to ensure water sustainability by introducing water purification faucets and cartridges in areas with access to tap water to provide safer and better-tasting water.

LIXIL Public Partners (LPP) Water and Sanitation Initiatives

LIXIL Public Partners (LPP) is an organization that seeks to strengthen cooperation between the public and private sectors in water, sanitation, and hygiene. LPP is currently conducting trials to introduce wastewater treatment facilities and water-efficient fixtures and fittings in rural areas of the US without access to public sewage systems. Through these trials, we are working to reduce the risk of groundwater contamination by increasing access to safely managed sanitation services and safer water, while accelerating the expansion of the public-private partnership model globally in the future.
