      Positive Climate Impact - A Cleaner Alternative to Trucked Water

      Supplying clean water by trucking is costly, fuel-intensive, and carbon-heavy. OPUS® One provides a dramatically cleaner and more sustainable alternative.

      Massive CO₂ Savings

      Water trucking typically requires:
      • Diesel-powered transport
      • Long driving distances
      • Frequent return trips
      • Heavy vehicle operation with high emissions per liter delivered
      With OPUS® One:
      • Zero fuel use
      • Zero electricity
      • Zero emissions at the point of use
      • Local purification means no transport emissions
      • No need for plastic water containers or bottled water

      A community using OPUS® One instead of trucked water can reduce annual CO₂ emissions by several tons, depending on distance and frequency.

      Climate-Resilient Water Security

      As climate change increases droughts, floods, and infrastructure failures, OPUS® One ensures rural and vulnerable communities remain water-secure even when logistics collapse.

      Advanced Five-Stage Purification

      At the heart of OPUS® One is an advanced five-stage purification system designed to transform contaminated surface water into safe, high-quality drinking water. Each stage plays a specific role, progressively removing debris, suspended particles, harmful chemicals, heavy metals, bacteria, viruses, and other waterborne contaminants. By combining proven filtration media with advanced UVC-LED disinfection, the system delivers reliable purification without the use of electricity or chemical additives. Together, these five stages ensure consistent performance, maximum water quality, and dependable access to clean drinking water—even in the world’s most challenging environments.

      Depending on the quality and type of contamination in the source water, stages 2, 3, and 4 can be configured with different filter media to achieve optimal purification. This flexible design allows OPUS® One to address a wide range of water quality challenges, including suspended solids, organic pollutants, heavy metals, ammonia, and harmful microorganisms. By selecting the most suitable filtration combination for local conditions, the system delivers efficient, reliable, and application-specific water treatment in virtually any environment.
