After 40 years of use the KfW decided
to completely renovate its four office
towers. For the drainage of the total of
19 floors special attention was paid on a
very economical use of freshwater.

sanitation technology reduced the
freshwater consumption significantly
Due to the high number of users the
ROI for the ROEDIGER® sanitation
system was reached after three
years only !
