ECO Grey Water Reuse System

The ECO Grey Water Reuse System saves up to 250 liters of potable water per flight.**

** estimated for a state-of-the-art aircraft, e.g. Boeing 787, operating on long range missions, e.g. London-Los Angeles, with average operating hours of 4.100 h per year

When integrating the ECO Grey Water Reuse System, the operating take-off weight of an aircraft can be reduced by 220 kg.**

** estimated for a state-of-the-art aircraft, e.g. Boeing 787, operating on long range missions, e.g. London-Los Angeles, with average operating hours of 4.100 h per year

With the reduced operating weight of 220 kg, we can estimate a fuel saving of 28 tons per aircraft per year.

This fuel saving can be converted into a CO2 emission saving of 90 tons per aircraft and per year.**

Sustainable water technology - our contribution for a clean environment

Future lavatories on board of an aircraft will be able to reduce the consumption of potable water and CO2 emissions substantially. The ECO Grey Water Reuse System collects the hand wash water and utilizes it for flushing the toilet. In general, the system enables a potable water saving of up to 25%, for example at a Boeing 787, this relatively simple method can save up to 250 liters of potable water per flight. Thanks to this weight saving, the CO2 emissions of a state-of-the-art widebody aircraft under typical operating conditions, can be reduced by up to 90 tons per year and thus reduced operating costs as well.

Diehl Aviation’s innovative design stands for clean and future-proof lavatory solutions and has integrally taken all challenges of hygiene technology into consideration. The entire system has less than 3 kg in weight per lavatory and is very reliable along with the safety regarding bacteria and odors.
