A small, simple invention that reuses the water used to cool ice machine compressors
has allowed the Hilton Cebu Resort & Spa to recycle hundreds of thousands of litres of
water each year and created huge savings on the hotelís water bill.
The invention, a simple piping system, is attached to three ice machines in the hotel,
capturing the water used to cool the compressors and then sending this Ďgrey waterí to
be reused in the hotelís flushing tanks, rather than simply washing down the drain.
The system was created as part of a water saving project led by Hilton Cebuís Chief
Engineer Antonio Dizon and team members Junar Penalosa and Gaspar Pasucal, who
were looking at ways to boost the resortís environmental efforts.
General Manager Harald Feurstein said the engineering teamís effort was a victory for
Hilton Cebuís efforts to be more eco-friendly and it had been well received by guests as
well as hotel staff.
ďBy just not letting that water disappear down the drain we are saving and then reusing
around 32,400 cubic meters of precious water in a year, and that in turn saves the hotel
approximately US$20,000 per year,Ē said Mr. Feurstein.
Special meters attached to the piping system revealed the project had saved Hilton
Cebu the initial setup cost of US$1,000 in just 20 days of operation and the system has
now been adopted as part of Hilton Hotels Groupís best practice for all its properties
around the world.
Mr. Feurstein said, ďLocated on a private beach overlooking the pristine, azure waters
surrounding Cebuís Mactan Island we are very concerned with preserving our
environment as it is a huge part of our business. However any hotel, anywhere in the
world can see the excellent improvement this has made to our bottom line and consider
both the economic and eco-friendly benefits of saving an important resource such
