Bad Hersfeld Hospital

The hospital in Bad Hersfeld has long experience in rainwater harvesting - an ecological commitment that saved about € 13,500 in 2007.

For 2008, pond and irrigation were estimated with 40 m³ demand of water. Additionally the toilet flushing was estimated with 1,801 m³ per year. In addition, 1,107 m³ of softened mains water could be saved for cooling vacuum pumps. Thus, the contribution of rainwater harvesting had a volume of 2,948 m³ of water.

The rainwater storage tank built in 1995 is made of steel, the additional battery of 8 plastic tanks was installed in 2001. Both cisterns are connected to each other and are fed with rainwater in parallel. One vortex fine filter from WISY AG is installed in front of each storage tank. Particles are automatically flushed into the wastewater pipe without clogging the filter or having to be disposed of. This results in high efficiency and a long service life, i.e. safe and effective operation.
