Use of the WFF 300 vortex fine filter
Object data
Eiffel Palace, Budapest | 2014
Project information
In the heart of Budapest, the restoration of the Eiffel Palace combined stylish historical architecture with sustainable building technology. The result is an impressive office building, playfully romantic and at the same time clearly modern. It is awarded with two certifications for ecological building, LEED and BREEAM, which is to a certain extend due to the implementation of rainwater harvesting.

Certification
The certification according to LEED (Leadership in Energy and Environmental Design) with the "Gold" award and the "Very Good" award according to the BREEAM standard (BRE Environmental Assessment Method) elevate the Eiffel Palace with this double award to the building with the highest awards for sustainability in Hungary.
Rainwater harvesting
One component of the ecological building technology is the rainwater harvesting system that supplies the numerous toilets with flush water. Of the 2500 square metre roof, an approximately 1400 square metre metal area is available for the collection of rainwater. The remaining roof area is designed as a green roof. The rainwater enters a concrete storage tank with a useful volume of 250 cubic metres via two self-cleaning WISY vortex fine filters connected in parallel. Two pumps installed in the storage tank provide the necessary volume flow and operating pressure for the toilet flushes. A mains water feed with a convenient control system ensures the operation of the rainwater harvesting system and informs the building services technician about various operating parameters of the system.
The special installation situation of the rainwater storage tank on the 5th basement level within the underground car park required additional planning measures for the drainage. The dirty water separated by the vortex fine filters is collected in plastic containers and lifted into the public sewage system by means of four pumps.
Through the installation of the rainwater harvesting system, the annual saving amounts to approx. 700 cubic metres of mains water for the building.
