The aim of SANIRESCH (SANItaryRecycling ESCHborn) is the treatment and recycling of the urine, brown- and greywater collected at the headquarters of  German Technical Cooperation (GTZ) GmbH in Eschborn, Germany.

Technologies for the treatment of wastewater streams (MAP precipitation, membrane bioreactors) as well as reuse in agriculture will be developed further within this project. Moreover, important questions regarding the further development of sanitary equipment and installtions, the operation and maintenance, the user acceptance, the environmental and health risks of the reuse, the economics and resource efficiency as well as the legal conditions and the transferability of such technologies to other countries will be investigated.

The GTZ implemented a system for the separate collection of urine and brownwater during the renovation of its headquarters (Building 1) in Eschborn. This system consists of urine-diversion flush toilets, waterless urinals, separate piping systems for urine, brownwater and greywater and tanks for urine storage.

SANIRESCH is financed by the Federal Ministry of Education and Research from July 2009 till June 2012. The project partners are the University of Applied Siences Gießen-Friedberg, the German Technical Cooperation GmbH, Huber SE, Roediger Vacuum, RWTH Aachen, and the University of Bonn.
