Industries

  • Wastewater Treatment

    The goal of waste water treatment is to produce treated water that meets environmental regulations and can be safely released into bodies of water or reused for purposes like irrigation or industrial processes.

  • Water & Wastewater

    All water, regardless of its source, has value. However, with water resources being finite, a focus on "One Water" is necessary to maximize every drop within the water system, ensuring a stable supply of clean and safe water.  As we consider current and future needs, planning and implementation are critical for long-term resilience and reliability, meeting both community and ecosystem demands. Yokogawa believes water is a human right for all. Thus, contributing to a sustainable water cycle is one of our Sustainable Development Goals (SDGs).
