McDonald's branch opts for rainwater
Double rainwater application for system gastronomers in Dortmund / Germany / 2008
Rainwater harvesting and attenuation
RAINMASTER Favorit, PURAIN Filter
Today McDonald's is the global market leader in system catering. There are now over 1,361 branches with approx. 60,000 employees. At the newly opened branch in Dortmund, Kleyer Weg, an intelligent rainwater utilisation system was installed in addition to a large rainwater retention system. The rainwater from part of the roof area is cleaned in a 10 m³ concrete cistern with PURAIN DN150 filter and stored for flushing the toilet facilities. For reasons of supply security, a double pump system was required. The optimal solution: RAINMASTER Favorit Duplex - two high quality rainwater plants with speed control and Bluetooth control. This means a significant reduction in energy and noise, a significantly higher life expectancy and the best operational reliability with redundancy.
