Centre, which is equipped with building automation, security
and fire safety solutions from Siemens.
In our global water R&D center in Singapore, Siemens scien-
tists are working in close cooperation with other experts
to develop solutions that will help supply the city with clean
drinking water.
Steffen Endler “Singapore is a sophisticated
pilot customer. That’s why the
cooperation with the city is very
important for us.”

The commonly used systems today for sea water desali-
nation need around . kWh/m for sea water to desalt.
The best available technologies today need roughly . to
4.0 kWh/m3, but we now have a development project which
is aiming for 1.5 kWh/m3. Over the past two years, we have
been developing this new desalination technology, and
since December 2010, we have been operating a pilot unit
at one of the PUB water plants. It will take a little more time
to upscale it to a fully commercial-sized application, but
once ready, this techno l ogy will be relevant and applicable
all around the globe. Besides desalination, we have other
technologies which we develop here in our global R&D
center. For instance, we are looking into advanced biolog-
ical waste water treatment. We can generate energy while
treating nutrient-rich wastewater. So eventually, we are
aiming to perform wastewater treatment with zero energy
consumption.
