In hotel rooms, air conditioning condensate is taken to the nearest drain point which is generally adjacent to the toilets.
Therefore, Encore uses the condensate far quicker as it only has a short distance to travel. Large-scale collection systems, however, direct all the greywater and condensate to tanks in hotel basements.
This requires a large amount of space within the hotel and a significant financial outlay – typically in the region of £100,000 for a 250-bed hotel. The water and condensate then goes through an extensive purification process as it passes through large, expensive equipment including collection tanks, purifiers and filtration tanks before powerful electrical pumps (which use a lot of energy) send it back through the building to be reused.
This process also duplicates the amount of pipework and drainage required. With Encore, it is a shorter process, more energy efficient and cheaper financially.
