Water footprint of a flow controller by NEOPERL GmbH

Water scarcity is a local but serious problem that affects around 1.6 billion people around the world. NEOPERL GmbH products, such as flow and jet regulators, help save water. Water savings also save energy and reduce greenhouse gas emissions required for extraction and treatment. Since these positive environmental effects have so far been assessed and communicated qualitatively, but not quantitatively, the project aims to answer the following questions:

  • Which methods and tools are available to measure the water consumption (or water savings) of a product and evaluate its local consequences?
  • How high are water consumption (or water savings) and resulting ecological / health impacts (or positive effects) along the life cycle of a flow regulator by NEOPERL GmbH?
  • Which changed ecological and health impacts result from the water consumption of a similar production method used by competitors in China, where there is a much greater water scarcity than in southern Germany?
  • How high are the energy consumption and greenhouse gas emissions along the life cycle of a Neoperl flow controller? Especially taking into account the costs for production and disposal as well as less water used for treatment and during use?
