Water consumption significantly reduced since 2010

EVVA’s headquarters are located in a water conservation area, which is why it is important to us to use this resource sustainably. EVVA does not recirculate water, but consumes it outright. We need water for production processes that have not yet been converted to clean production, i.e. currently for approx. 20% of production facilities, as well as for electroplating (surface treatment of products) and personal hygiene.

EVVA has continuously reduced water consumption at the headquarters in order to conserve this resource as much as possible. In 2010, EVVA's water consumption still stood at 7,153 m³ of water. In 2024, demand fell to 4,191 m³ (measurement data for 2025 will only be available in the course of 2026). Water consumption is almost entirely related to personal care/hygiene, with only 6 m³ attributable to electroplating. Thanks to the vacuum evaporator (see below), EVVA requires almost no water for electroplating, and consumption is minimised to 250 litres per 100-hour cycle.

EVVA has thus managed to reduce water consumption by over 40% since 2010 through wastewater recovery and optimisation measures. 
 
Lower fresh water consumption

Reasons for water savings in recent years:

• 

  EVVA uses many clean production machines that do not require water 


• more efficient manufacturing and water treatment processes in electroplating (for the surface treatment of our products). Among other things, this was made possible by a new, modern wastewater treatment plant.
   
• New valves in the shower/washing facilities that regulate the water supply in a more resource-efficient way
   
• A vacuum evaporator treats the wastewater from the electroplating process 100% and returns it to the production cycle. This means that only the waste water used for personal hygiene (washbasins, showers, toilets) flows into the public sewer system, but not the waste water from electroplating – this is completely recycled via the vacuum evaporator!
