Expertise – storing and using rainwater underground

Environmental protection and resource conservation are becoming increasingly important. That is why more and more people want to use rainwater instead of expensive drinking water. With our many years of experience in rainwater utilisation, we support our customers in all questions concerning the installation of a cistern.
At www.zisterne.info we offer cisterns and rainwater tanks in all sizes and shapes.

Expertise – Decentralised rainwater infiltration

Due to increasing urbanisation, the infiltration of rainwater on site is becoming more and more important. Due to the sealing of surfaces, intelligent solutions are required to return surface water to the soil and groundwater. BRAUN supports its customers in all questions of infiltration and offers suitable solutions at www.sickerschacht.com.

Our customers can find further information such as dimensioning of infiltration systems, legal framework conditions and differences between the various systems at www.versickerung.org
