Description

In addition to a number of other stores, the new "Weide Park" retail park in Kranenburg also included a new REWE supermarket. From now on, numerous products will be offered here on an area of more than 2,000 square meters.

Under the motto "Marketplace of Freshness", the store manager is relying on green and blue building technology for his operation. As a green building, the store is to receive DGNB gold certification. In addition to natural sunlight for lighting, the store also relies on the use of rainwater to conserve drinking water.

A PURAIN HD200 with DN250 inlet and outlet, as well as an almost 8,000-liter cistern built into the ground, ensure flawless flush water for toilets and urinals. This type of sustainable construction demonstrates how simple it can be to implement resource-saving techniques in relation to water.
