Smile Water

Protecting life
and creating smiles with water.
The social contribution efforts of Sumitomo Electric.

The severity of global water problems continues to escalate,
brought on by the growing world population, modernization of emerging countries,
and water shortages due to climate change. Despite its abundant water resources,
threats to vital water supplies due to floods caused by heavy rains, earthquakes, and natural disasters is increasing every year.
Sumitomo Electric is developing emergency water regeneration system, as part of the business continuity plans of office buildings, hospitals and local governments.
Our goal is to create a society with zero-water-supply risk.
Our challenge is endless.

Corporate social responsibility activities that contribute to the achievement of Sustainable Development Goals
The Sustainable Development Goals (SDGs) adopted by the United Nations in September 2015 are a master plan to achieve a sustainable society by 2030 by achieving 17 global goals and 169 targets.
Sumitomo Electric's Water Processing Division is using projects connected with the SDGs and its corporate social responsibility activities to contribute to three areas: Goal 6. Clean Water and Sanitation, Goal 9. Industry, Innovation and Infrastructure, and Goal 14. Life Below Water. Our aim is sustainable development of communities and societies around the world, and we are making steady and innovative efforts in pursuit of this aim.
  1. SDGs
    Case Study

    Responding to water quality regulations for domestic wastewater

    Hunan Province, China

    In many rural areas of China, domestic wastewater is discharged into rivers, creating an environmental pollution problem. In 2015, the government enforced strict water quality regulations on wastewater.

    Sumitomo Electric introduced wastewater treatment equipment that uses the POREFLON (MF/UF) Membrane Module in agricultural villages and conducted field tests. Highly praised for its excellent treatment capability, durability and stable long-term operability, this wastewater treatment equipment is now in service in more than 70 villages. We will continue to promote water treatment and maintenance projects in various regions to ensure that more people have access to clean water. We will work on activities to preserve our oceans, rivers and other natural environments.

    Goal 6: Clean Water and Sanitation, Goal 14: Life Below Water
  2. SDGs
    Case Study

    The challenge of reusing industrial wastewater

    Kaohsiung, Taiwan

    In southern Taiwan, where rainfall is low and water shortages are becoming severe, businesses must reuse 85% or more of their industrial wastewater.

    Sumitomo Electric took part in a wastewater purification project at a large-scale refinery. Through repeated on-site demonstration tests and improvements, Sumitomo could achieve high and consistent quality of treated water, excellent operation performance with less energy consumption as well as high recovery rate. By implementing a water treatment facility with a focus on the environment, we were able to help improve the water reuse rate in an area with limited water resources.

    Goal 9: Industry, Innovation and Infrastructure
  3. SDGs
    Case Study

    Reusing injection water in oil field drilling

    Texas, U.S.

    In oil fields with low-pressure oil reservoirs, water is injected into the oil field to push oil to the surface and increase production. This hydraulic injection produces large amounts of water with oil and sediment into the groundwater, which contaminates the domestic water supply.

    Sumitomo Electric developed a wastewater treatment and reuse system for hydraulic injection, and successfully demonstrated treatment of large amounts of oil-contaminated wastewater. We also promote activities that help ensure communities have access to clean water and protect the natural environment.
